Bitcoin energy use – mined the gap

Published

on

Of all the potential implications of blockchain for the energy sector, the energy use of cryptocurrencies – and bitcoin in particular – has captured the most interest.

As the price of bitcoin skyrocketed in 2017, attention turned to the cryptocurrency’s energy and environmental footprint. High-profile news articles reported that electricity use of the bitcoin network had equalled that of medium-sized countries and was on track to consume as much electricity as the United States in 2019 and all of the world’s energy by 2020. A widely reported article in Nature Climate Change warned that Bitcoin emissions alone could push global warming above 2°C.

With bitcoin value tripling in recent months and Facebook announcing its new Libra coin, interest in the energy use of cryptocurrencies is again on the rise.

In this commentary, we explain why and how bitcoin uses energy; dig into published estimates of bitcoin energy use and provide our own analysis; and discuss how these trends might evolve in the coming years.

Why does bitcoin use energy?

In order to understand why and how bitcoin uses energy, we first need to understand its underlying technology: blockchain. Blockchain offers a new way to conduct and record transactions, like sending money. In a traditional exchange, central authorities (e.g. banks) verify and log transactions. Blockchain removes the need for a central authority and ledger; instead, the ledger is held, shared, and validated across a distributed network of computers running a particular blockchain software.

The lack of a centralised, trusted authority means that blockchain needs a “consensus mechanism” to ensure trust across the network. In the case of bitcoin, consensus is achieved by a method called “Proof-of-Work” (PoW), where computers on the network – “miners” – compete with each other to solve a complex math puzzle. Each guess a miner makes at the solution is known as a “hash,” while the number of guesses taken by the miner each second is known as its “hashrate.” Once the puzzle is solved, the latest “block” of transactions is approved and added to the “chain” of transactions. The first miner to solve the puzzle is rewarded with new bitcoins and network transaction fees. The energy use of the bitcoin network is therefore both a security feature and a side effect of relying on the ever-increasing computing power of competing miners to validate transactions through PoW.

How does bitcoin use energy?

The energy use of the bitcoin network is a function of a few inter-related factors (some of which respond to the changing price of bitcoin):

  1. mining hardware specifications, notably power consumption and hashrate;
  2. network hashrate, the combined rate at which all miners on the network are simultaneously guessing solutions to the puzzle;
  3. difficulty” of solving the puzzle, which is adjusted in response to the network hashrate to maintain the target block rate of one block every 10 minutes; and
  4. energy consumption by non-IT infrastructure, such as cooling and lighting.

The rising price of bitcoin, particularly as it rose to all-time highs in December 2017, drove huge increases in hashrate and difficulty, and the development and deployment of more powerful and energy efficient mining hardware.

The IT infrastructure for bitcoin and other cryptocurrencies has evolved rapidly over the past decade. In the early days of bitcoin (2009), hobbyists used standard central processing units (CPUs) to mine bitcoin. By October 2010, miners started to use more powerful graphics processing units (GPUs) as mining difficulty increased. By June 2011, miners – increasingly large and more industrial operations – used more powerful (but less energy-efficient) field-programmable gate array (FPGA) hardware, and a year later, moved to application-specific integrated circuits (ASICs).

ASICs are purpose-built chips, in this case, to mine bitcoin. The latest ASICs are both more powerful and more energy efficient – around 50 million times faster (H/s) and a million times more energy efficient (H/J) in mining bitcoin than the CPUs used in 2009.

How much energy is bitcoin using today?

Diverse methodologies, limited data availability, and highly variable conditions across the industry (e.g. mining hardware used; electricity costs; cooling needs) make estimating bitcoin energy use extremely challenging (Koomey, 2019). Therefore, all estimates must be interpreted with caution.

Recent published estimates of bitcoin’s electricity consumption are wide-ranging, on the order of 20‑80 TWh annually, or about 0.1-0.3% of global electricity use (Bendiksen & Gibbons, 2018; Bendiksen & Gibbons, 2019; Bendiksen, Gibbons & Lim, 2018; Bevand, 2018; BNEF, 2018; De Vries, 2018; Digiconomist, 2019; Krause & Tolaymat, 2018; Morgan Stanley, 2018; Rauchs et al., 2018; Stoll et al., 2019; Vranken, 2017).

These figures can appear large when compared to countries like Ireland (26 TWh) or emerging technologies like electric vehicles (58 TWh in 2018), but small when compared to other end-uses like cooling (2 020 TWh in 2016). Nonetheless, bitcoin mining is a highly mobile industry, allowing it to migrate quickly to areas with cheap electricity. Localised hotspots and electricity supply issues can emerge quickly, generating strong backlash from regulators and the public.

Bitcoin has also been compared on a per-transaction basis to VISA payments, the broader banking system, and gold mining. However, comparisons on a per-transaction basis are not meaningful in the context of PoW blockchains, particularly because the energy required for the networks to function is independent of the number of processed transactions. A recent peer-reviewed article compared the energy intensity of mining bitcoin (17 MJ/USD) to the mining of other metals like aluminium (122 MJ/USD) and gold (5 MJ/USD).

Comparing methodologies

By far, the most frequently cited estimate in news media is the Bitcoin Energy Consumption Index (BECI), which uses a top-down approach that assumes miners spend (on average) 60% of their revenues on electricity at a rate of 0.05 USD/kWh. These key assumptions have been criticised to overestimate electricity consumption; indeed, BECI estimates represent the high range of published estimates to date.

Bendiksen, Gibbons (2018; 2019) & Lim (2018) also use a top-down approach, but undertake significant data collection efforts on existing mining hardware and mining locations to inform their assumptions and analysis. They also conduct sensitivity analyses around key uncertainties, including electricity costs and capital depreciation schedules. Under their central assumptions, they estimate that the bitcoin network consumes between 35 TWh (May 2018) and 41 TWh (November 2018; June 2019) per year.

Other researchers have calculated lower-bound estimates using a bottom-up approach (e.g. Deetman, 2016; Morgan Stanley, 2018; Valfells & Egilsson, 2016). This approach assumes that all miners are using the most efficient mining hardware to achieve the network’s hashrates (TH/s). The Bitmain Antminer S9 series (0.1 J/GH), used by two-thirds of miners worldwide, is typically used as a benchmark.

Using this approach, we can estimate that thebitcoin network (excluding cooling) consumed 31 TWh in 2018. Based on data collected from mining facilities in China, cooling and other ancillary demands accounts for 30% of electricity use overall, thereby adding another 42% to the lower-bound estimate. Therefore, we estimate that bitcoin mining consumed around 45 TWh in 2018, which aligns well with the latest peer-reviewed estimate of 45.8 TWh as of November 2018 (Stoll et al., 2019).

With the recent run up in price and hashrate, energy consumption is expected to be much higher in 2019. Through the first six months of 2019, bitcoin mining has already consumed an estimated 29 TWh.

While these early estimates provide a rough indication of bitcoin energy use today, it is clear that researchers need more data, in particular from mining facilities, to develop more rigorous methodologies and accurate estimates.

Bitcoin and climate change

Headlines concerning the environmental impacts of bitcoin re-emerged last October, when a commentary article from Mora et al. in Nature Climate Change concluded that “…projected Bitcoin usage, should it follow the rate of adoption of other broadly adopted technologies, could alone produce enough CO2 emissions to push warming above 2°C within less than three decades”.

A closer look reveals serious issues in the study’s methodology and assumptions, notably around bitcoin adoption rates, the efficiency of mining hardware, and the assumed electricity mix (Masanet et al., 2019, Nature Climate Change, In Press). Crucially, the use of country average (and in some cases, world average) emissions factors inflates the GHG estimates, since bitcoin mines are typically concentrated in renewables-rich states and provinces.

Indeed, the selection of mining locations depend on a balance of several key factors, including access to low-cost electricity, fast internet connections, cool climates, and favourable regulatory environments. For these reasons, China, Iceland, Sweden, Norway, Georgia, the Pacific North West (Washington State, British Columbia, Oregon), Quebec, and upstate New York are key bitcoin mining centres.

Around 60% to 70% of bitcoin is currently mined in China, where more than two-thirds of electricity generation comes from coal. But bitcoin mining facilities are concentrated in remote areas of China with rich hydro or wind resources (cheap electricity), with about 80% of Chinese bitcoin mining occurring in hydro-rich Sichuan province. These mining facilities may be absorbing overcapacity in some of these regions, using renewable energy that would otherwise be unused, given difficulties in matching these rich wind and hydro resources with demand centres on the coast.

Electricity generation in other key bitcoin mining centres are also dominated by renewables, including Iceland (100%), Quebec (99.8%), British Columbia (98.4%), Norway (98%), and Georgia (81%). Globally, one analysis estimates that the bitcoin is powered by at least 74% renewable electricity as of June 2019. Another analysis of data from 93 mining facilities (representing 1.7 GW, or about a third of global mining capacity) estimates that 76% of the identified energy mix includes renewables.

Based on these analyses and data from IPO filings of hardware manufacturers and insights on mining facility operations and pool compositions, bitcoin mining is likely responsible for 10‑20 Mt CO2 per year, or 0.03-0.06% of global energy-related CO2 emissions.

Outlook for bitcoin energy use and emissions

Apocalyptic headlines that bitcoin would consume all of the world’s energy by 2020 echo back to warnings from the late 1990s about the internet and its growing appetite for energy, including one Forbes article in 1999 that predicted that “[…]half of the electric grid will be powering the digital-Internet economy within the next decade”.

Since then, researchers have collected real-world data and developed and refined methodologies to establish rigorous estimates of the energy use of data centres and the global ICT sector, including by the IEA. The dire predictions about the energy use of the internet failed to materialise despite exponential growth in internet services, largely because of rapid improvements in the energy efficiency of computing and data transmission networks.

The outlook for bitcoin energy use is highly uncertain, hinging on efficiency improvements in hardware, bitcoin price trends, and regulatory restrictions on bitcoin mining or use in key markets. Bitcoin prices in particular are extremely volatile: between December 2017 and 2018, its value fell by 80%, but has nearly tripled since.

It is important to recognise that bitcoin is just one cryptocurrency, which is one application of blockchain, which is itself one example of distributed ledger technology (DLT). Ethereum (ETH), the second largest cryptocurrency by market value, processes more than twice as many transactions as the bitcoin network while using only about one-third of the electricity consumed by bitcoin. ETH also operates on a Proof-of-Work (PoW) consensus mechanism, but its founder has announced plans to move to Proof-of-Stake (PoS) in an effort to reduce its energy intensity. PoS and Proof‑of‑Authority (PoA) could help reduce energy use while also addressing scalability and latency issues. Other DLTs like Tangle and Hashgraph similarly offer the promise of lower energy use, scalability, faster transactions, and no transaction fees compared to blockchain.

Over the coming years, other applications of blockchain – including those within the energy sector – are likely to garner more attention. As the scope and scale of blockchain applications increases, these trends combined are likely to materially reduce the future energy footprint of its technology.

Sensational predictions about bitcoin consuming the entire world’s electricity – and, by itself, leading our world to beyond 2°C – would appear just that…sensational. That said, this is a very dynamic area that certainly requires careful monitoring and rigorous analysis – particularly, a careful monitoring of local hotspots.

The energy use of bitcoin and blockchain is just part of the blockchain and energy story. In our next commentary, we’ll look at how blockchain is already impacting the energy sector, dive into some of the most promising applications, and explore the technological, regulatory or market design challenges that await.

Oil and the new world order: China, Iran and Eurasia

Published

on

The world oil market will undergo a fundamental change in the future. Choosing petrodollars or oil wars is no longer a question that can be answered. With the Strategic Agreement on the Comprehensive Economic and Security Partnership between China and Iran officially signed by the Foreign Ministers of both countries in Tehran on March 27, 2021, the petrodollar theorem is broken and the empire built by the US dollar is cracked.

This is because the petrodollar has not brought substantial economic development to the oil-producing countries in the Middle East during over half a century of linkage to the US dollar.

The Middle East countries generally have not their own industrial systems. The national economies are heavily dependent on oil exports and imports of cereals and industrial products. The national finances are driven by the US dollar and the financial system that follows it.

If the Middle East countries wanted to escape the control of the dollar, they should face the threat of war from the United States and its allies – things we have seen over and over again. Just think of Saddam Hussein being supported when he was fighting Iran and later being Public Enemy No. 1 when he started trading oil in euros.

The West has always wanted the Middle East to be an oil ‘sacred cow’ and has not enabled it to develop its own modern industrial system: the lack of progress in the Middle East was intended as long-term blackmail.

In the Western system of civilisation based on exchange of views and competition, the West is concerned that Iran and the entire Middle East may once again restore the former glory and hegemony of the Persian, Arab and Ottoman empires.

China is facing the exploitation of the global oil market and the threat of its supply disruption. Relying on industrial, financial, and military strength, Europe and the United States control the oil production capital, trade markets, dollar settlements, and global waterways that make up the entire petrodollar world order, differentiating China and the Middle East and dividing the world on the basis of the well-known considerations. You either choose the dollar or you choose war – and the dollar has long been suffering.

Just as in ancient times nomadic tribes blocked the Silk Road and monopolised trade between East and West, Europe and the United States are holding back and halting cooperation and development of the whole of Asia and the rest of the planet. Centuries ago, it was a prairie cavalry, bows, arrows and scimitars: today it is a navy ship and a financial system denominated in dollars.

Therefore, China and Iran, as well as the entire Middle East, are currently looking for ways to avoid middlemen and intermediaries and make the difference. If there is another strong power that can provide military security and at the same time offer sufficient funds and industrial products, the whole Middle East oil can be freed from the dominance of the dollar and can trade directly to meet demand, and even introduce new modern industrial systems.

Keeping oil away from the US dollar and wars and using oil for cooperation, mutual assistance and common development is the inner voice of the entire Middle East and developing countries: a power that together cannot be ignored in the world.

The former Soviet Union had hoped to use that power and strength to improve its system. However, it overemphasised its own geostrategic and paracolonial interests – turning itself into a social-imperialist superpower competing with the White House. Moreover, the USSR lacked a cooperative and shared mechanism to strengthen its alliances, and eventually its own cronies began to rebel as early as the 1960s.

More importantly – although the Soviet Union at the time could provide military security guarantees for allied countries – it was difficult for it to provide economic guarantees and markets, although the Soviet Union itself was a major oil exporter. The natural competitive relationship between the Soviet Union and the Middle East, as well as the Soviet Union’s weak industrial capacity, eventually led to the disintegration of the whole system, starting with the defection of Sadat’s Egypt in 1972. Hence the world reverted to the unipolarised dollar governance once the Soviet katekon collapsed nineteen years later.

With the development and rise of its economy, however, now China has also begun to enter the world scene and needs to establish its own new world order, after being treated as a trading post by Britain in the 19th century, later divided into zones of influence by the West and Japan, and then quarantined by the United States after the Second World War.

Unlike the US and Soviet world order, China’s proposal is not a paracolonial project based on its own national interests, nor is it an old-fashioned “African globalisation” plan based on multinationals, and it is certainly not an ideological export.

For years, there has been talk of Socialism with Chinese characteristics and certainly not of attempts to impose China’s Marxism on the rest of the world, as was the case with Russia. China, instead, wishes to have a new international economic order characterised by cooperation, mutual assistance and common development.

Unlike the Western civilisation based on rivalry and competition, the Eastern civilisation, which pays more attention to harmony without differences and to coordinated development, is trying to establish a new world economic order with a completely different model from those that wrote history in blood.

Reverting to the previous treaty, between the US dollar and the war, China has offered Iran and even the world a third choice. China seems increasingly willing to exist as a service provider. This seems to be more useful for China, first of all to solve its own problems and not to get involved in endless international disputes.

It can thus be more accepted by all countries around the world and unite more States to break the joint encirclement of the “democratic” and liberal imperialism of Europe and the United States.

Consequently, China and Iran – whose origins date back almost to the same period – met at a critical moment in history. According to the Strategic Agreement on Comprehensive Economic and Security Partnership between China and Iran, China will invest up to 400 billion dollars in dozens of oil fields in Iran over the next 25 years, as well as in banking, telecommunications, ports, railways, healthcare, 5G networks, GPS, etc.

China will help Iran build the entire modern industrial system. At the same time, it will receive a heavily discounted and long-term stable supply of Iranian oil. The Sino-Iranian partnership will lay the foundations for a proposed new world order, with great respect for Eastern values, not based on some failed, decadent and increasingly radicalising principles.

Faced with the value restraint and the pressure of sanctions from the United States and Europe, China is seeking to unite the European third Rome, Indo-European Iran, the second Rome and the five Central Asian countries to create a powerful geoeconomic counterpart in the hinterland of Eurasia.

The stages and choices of energy production from hydrogen

Published

on

There are three main ways to use hydrogen energy:

1) internal combustion;

2) conversion to electricity using a fuel cell;

3) nuclear fusion.

The basic principle of a hydrogen internal combustion engine is the same as that of a gasoline or diesel internal combustion engine. The hydrogen internal combustion engine is a slightly modified version of the traditional gasoline internal combustion engine. Hydrogen internal combustion burns hydrogen directly without using other fuels or producing exhaust water vapour.

Hydrogen internal combustion engines do not require any expensive special environment or catalysts to fully do the job – hence there are no problems of excessive costs. Many successfully developed hydrogen internal combustion engines are hybrid, meaning they can use liquid hydrogen or gasoline as fuel.

The hydrogen internal combustion engine thus becomes a good transition product. For example, if you cannot reach your destination after refuelling, but you find a hydrogen refuelling station, you can use hydrogen as fuel. Or you can use liquid hydrogen first and then a regular refuelling station. Therefore, people will not be afraid of using hydrogen-powered vehicles when hydrogen refuelling stations are not yet widespread.

The hydrogen internal combustion engine has a small ignition energy; it is easy to achieve combustion – hence better fuel saving can be achieved under wider working conditions.

The application of hydrogen energy is mainly achieved through fuel cells. The safest and most efficient way to use it is to convert hydrogen energy into electricity through such cells.

The basic principle of hydrogen fuel cell power generation is the reverse reaction of electrolysis of water, hydrogen and oxygen supplied to the cathode and anode, respectively. The hydrogen spreading – after the electrolyte reaction – makes the emitted electrons reach the anode through the cathode by means of an external load.

The main difference between the hydrogen fuel cell and the ordinary battery is that the latter is an energy storage device that stores electrical energy and releases it when needed, while the hydrogen fuel cell is strictly a power generation device, like a power plant.

The same as an electrochemical power generation device that directly converts chemical energy into electrical energy. The use of hydrogen fuel cell to generate electricity, directly converts the combustion chemical energy into electrical energy without combustion.

The energy conversion rate can reach 60% to 80% and has a low pollution rate. The device can be large or small, and it is very flexible. Basically, hydrogen combustion batteries work differently from internal combustion engines: hydrogen combustion batteries generate electricity through chemical reactions to propel cars, while internal combustion engines use heat to drive cars.

Because the fuel cell vehicle does not entail combustion in the process, there is no mechanical loss or corrosion. The electricity generated by the hydrogen combustion battery can be used directly to drive the four wheels of the vehicle, thus leaving out the mechanical transmission device.

The countries that are developing research are aware that the hydrogen combustion engine battery will put an end to pollution. Technology research and development have already successfully produced hydrogen cell vehicles: the cutting-edge car-prucing industries include GM, Ford, Toyota, Mercedes-Benz, BMW and other major international companies.

In the case of nuclear fusion, the combination of hydrogen nuclei (deuterium and tritium) into heavier nuclei (helium) releases huge amounts of energy.

Thermonuclear reactions, or radical changes in atomic nuclei, are currently very promising new energy sources. The hydrogen nuclei involved in the nuclear reaction, such as hydrogen, deuterium, fluorine, lithium, iridium (obtained particularly from meteorites fallen on our planet), etc., obtain the necessary kinetic energy from thermal motion and cause the fusion reaction.

The thermonuclear reaction itself behind the hydrogen bomb explosion, which can produce a large amount of heat in an instant, cannot yet be used for peaceful purposes. Under specific conditions, however, the thermonuclear reaction can achieve a controlled thermonuclear reaction. This is an important aspect for experimental research. The controlled thermonuclear reaction is based on the fusion reactor. Once a fusion reactor is successful, it can provide mankind with the cleanest and most inexhaustible source of energy.

The feasibility of a larger controlled nuclear fusion reactor is tokamak. Tokamak is a toroidal-shaped device that uses a powerful magnetic field to confine plasma. Tokamak is one of several types of magnetic confinement devices developed to produce controlled thermonuclear fusion energy. As of 2021, it is the leading candidate for a fusion reactor.

The name tokamak comes from Russian (toroidal’naja kamera s magnitnymi katuškami: toroidal chamber with magnetic coils). Its magnetic configuration is the result of research conducted in 1950 by Soviet scientists Andrei Dmitrievič Sakharov (1921-1989) and Igor’ Evgen’evič Tamm (1895-1971), although the name dates back more precisely to 1957.

At the centre of tokamak there is a ring-shaped vacuum chamber with coils wound outside. When energized, a huge spiral magnetic field is generated inside the tokamak, which heats the plasma inside to a very high temperature, which achieves the purpose of nuclear fusion.

Energy, resources and environmental problems urgently need hydrogen energy to solve the environmental crisis, but the preparation of hydrogen energy is not yet mature, and most of the research on hydrogen storage materials is still in the exploratory laboratory stage. Hydrogen energy production should also focus on the “biological” production of hydrogen.

Other methods of hydrogen production are unsustainable and do not meet scientific development requirements. Within biological production, microbial production requires an organic combination of genetic engineering and chemical engineering so that existing technology can be fully used to develop hydrogen-producing organisms that meet requirements as soon as possible. Hydrogen production from biomass requires continuous improvement and a vigorous promotion of technology. It is a difficult process.

Hydrogen storage focused on the discovery of new aspects of materials or their preparation is not yet at large-scale industrial level. Considering different hydrogen storage mechanisms, and the material to be used, also needs further study.

Furthermore, each hydrogen storage material has its own advantages and disadvantages, and most storage material properties have the characteristics that relate to adductivity and properties of a single, more commonly known material.

It is therefore believed that efforts should be focused on the development of a composite hydrogen storage material, which integrates the storage advantages of multiple individual materials, along the lines of greater future efforts.

The advantages of hydrogen and Israel’s warnings

Published

on

Hydrogen is the most common element in nature. It is estimated to make up 75% of the mass of the universe. Except for that contained in air, it is primarily stored in water in the form of a compound, and water is the most widely distributed substance on earth.

Hydrogen has the best thermal conductivity of all gases – i.e. ten times higher than most of them – and it is therefore an excellent heat transfer carrier in the energy industry.

Hydrogen has good combustion performance, rapid ignition, and has a wide fuel range when mixed with air. It has a high ignition point and rapid combustion rate.

Except for nuclear fuels, the calorific value of hydrogen is the highest among all fossil and chemical fuels, as well as biofuels, reaching 142.35 kJ/kg. The calorie per kilogram of hydrogen burned is about three times that of gasoline and 3.9 times that of alcohol, as well as 4.5 times that of coke.

Hydrogen has the lightest weight of all elements. It can appear as gas, liquid, or solid metal hydride, which can adapt to different storage and transport needs and to various application environments.

Burning hydrogen is cleaner than other fuels –  besides generating small amounts of water – and does not produce hydrogen azide as carbon monoxide, carbon dioxide (harmful to the environment), hydrocarbons, lead compounds and dust particles, etc. A small amount of hydrogen nitride will not pollute the environment after proper treatment, and the water produced by combustion can continue to produce hydrogen and be reused repeatedly.

Extensive use practices show that hydrogen has a record of safe use. There were 145 hydrogen-related accidents in the United States between 1967 and 1977, all of which occurred in petroleum refining, the chlor-alkali industry, or nuclear power plants, and did not really involve energy applications.

Experience in the use of hydrogen shows that common hydrogen accidents can be summarized as follows: undetected leaks; safety valve failure; emptying system failure; broken pipes, tubes or containers; property damage; poor replacement; air or oxygen and other impurities left in the system; too high hydrogen discharge rate; possible damage of pipe and tube joints or bellows; accidents or tipping possibly occurring during the hydrogen transmission process.

These accidents require two additional conditions to cause a fire: one is the source of the fire and the other is the fact that the mixture of hydrogen and air or oxygen must be within the limits of the possibility of fires or violent earthquakes in the local area.

Under these two conditions, an accident cannot be caused if proper safety measures are established. In fact, with rigorous management and careful implementation of operating procedures, most accidents do not theoretically occur.

The development of hydrogen energy is triggering a profound energy revolution and could become the main source of energy in the 21st century.

The United States, Europe, Japan, and other developed countries have formulated long-term hydrogen energy development strategies from the perspective of national sustainable development and security strategies.

Israel, however, makes warning and calls for caution.

While the use of hydrogen allows for the widespread penetration of renewable energy, particularly solar and wind energy – which, due to storage difficulties, are less available than demand – Israeli experts say that, despite its many advantages, there are also disadvantages and barriers to integrating green hydrogen into industry, including high production costs and high upfront investment in infrastructure.

According to the Samuel Neaman Institute’s Energy Forum report (April 11, 2021; authors Professors Gershon Grossman and Naama Shapira), Israel is 7-10 years behind the world in producing energy from clean hydrogen.

Prof. Gideon Friedman, actingchief scientist and Director of Research and Development at the Ministry of Energy, explains why: “Israel has a small industry that is responsible for only 10% of greenhouse gas emissions – unlike the world where they are usually 20% – and therefore the problems of emissions in industry are a little less acute in the country.”

At a forum held prior to the report’s presentation, senior officials and energy experts highlighted the problematic nature of integrating clean hydrogen into industry in Israel.

Dr. Yossi Shavit, Head of the cyber unit in industry at the Ministry of Environmental Protection, outlined the risks inherent in hydrogen production, maintenance and transportation, including the fact that it is a colourless and odourless gas that makes it difficult to detect a leak. According to Dr. Shavit, hydrogen is a hazardous substance that has even been defined as such in a new regulation on cyber issues published in 2020.

Dr. Shlomo Wald, former chief scientist at the Ministry of Infrastructure, argued that in the future hydrogen would be used mainly for transportation, along with electricity.

Prof. Lior Elbaz of Bar-Ilan University said that one of the most important things is the lack of laws: “There is no specific regulation for hydrogen in Israel, but it is considered a dangerous substance. In order for hydrogen to be used for storage and transportation, there needs to be a serious set of laws that constitute a bottleneck in our learning curve.” “Israel has something to offer in innovation in the field, but government support will still be needed in this regard – as done in all countries – and approximately a trillion dollars in the field of hydrogen is expected to be invested in the next decade.”

Although the discussion was mainly about Israel’s delay in integrating clean hydrogen into the industry, it has emerged that Sonol (Israel’s fuel supplier ranking third in the country’s gas station chain) is leading a project, together with the Ministry of Transport, to establish Israel’s first hydrogen refuelling station. “We believe there will be hydrogen transportation in Israel for trucks and buses,” said Dr. Amichai Baram, Vice President of operations at Sonol. “Hydrogen-powered vehicles for the country – albeit not really cheap in the initial phase – and regulations promoted in the field, both for gas stations and vehicles.”

Renewables account for only 6% of Israel’s energy sources and, according to the latest plans published by the Ministry of Energy and adopted by the government, the target for 2030 is 30%.

This is an ambitious goal compared to reality, and also far from the goal of the rest of the countries in the world that aim at energy reset by 2050.

The authors of the aforementioned report emphasize that fully using the clean hydrogen potential is key to achieving a higher growth target for Israel.

According to recommendations, the State should critically examine the issue in accordance with Israel’s unique conditions and formulate a strategy for the optimal integration of hydrogen into the energy economy.

Furthermore, it must support implementation, both through appropriate regulations and through the promotion of cooperation with other countries and global companies, as well as through investment in infrastructure, and in research and development, industry and in collaboration with the academic world.

There are countries in Europe or the Middle East that have already started green energy production projects, and finally it was recommended to work to develop Israeli innovations in the field, in collaboration with the Innovation Authority and the Ministry of Energy.
