Are aviation biofuels ready for take off?

Published

on

Air travel is booming, with the number of air passengers set to double over the next twenty years. Aviation demand is particularly evident in in the Asia Pacific region, where growing economic wealth is opening new travel opportunities.

Aviation accounts for around 15% of global oil demand growth up to 2030 in the IEA’s New Policies Scenario, a similar amount to the growth from passenger vehicles. Such a rise means that aviation will account for 3.5% of global energy related CO2 emissions by 2030, up from just over 2.5% today, despite ongoing improvements in aviation efficiency.

This expansion underscores the need for the aviation industry to tackle its carbon emissions. For now, liquid hydrocarbon fuels like jet fuel remain the only means of powering commercial air travel. Therefore, along with a sustained improvement in energy efficiency, Sustainable Aviation Fuel (SAF) such as aviation biofuels are key to reducing aviation’s carbon emissions.

The International Civil Aviation Organization (ICAO), which governs international aviation, has committed to reducing carbon emissions by 50% from their 2005 level by 2050. Blending lower carbon SAF with fossil jet fuel will be essential to meeting this goal. This is reflected in the IEA’s Sustainable Development Scenario (SDS), which anticipates biofuels reaching around 10% of aviation fuel demand by 2030, and close to 20% by 2040.

The aviation industry demonstrates a strong commitment to sustainable aviation fuel use

The first flight using blended biofuel took place in 2008. Since then, more than 150,000 flights have used biofuels. Only five airports have regular biofuel distribution today (Bergen, Brisbane, Los Angeles, Oslo and Stockholm), with others offering occasional supply. But the centralised nature of aviation fuelling, where less than 5% of all airports handle 90% of international flights, means SAF availability at a small number of airports could cover a large share of demand.

Another indication of aviation’s commitment to growing SAF use is the agreement of long-term offtake agreements between airlines and biofuel producers. These now cumulatively cover around 6 billion litres of fuel. Meeting this demand will require further production facilities, and some airlines have directly invested in aviation biofuel refinery projects.

Still, aviation biofuel production of about 15 million litres in 2018 accounted for less than 0.1% of total aviation fuel consumption. This means that significantly faster market development is needed to deliver the levels of SAF production required by the aviation industry and keep on track with the requirements of the SDS. 

Technology development is essential to increase aviation biofuel availability

Currently, five aviation biofuel production pathways are approved for blending with fossil jet kerosene. However, only one – hydroprocessed esters and fatty acids synthetic paraffinic kerosene (HEFA-SPK) fuel – is currently technically mature and commercialised. Therefore, HEFA‑SPK is anticipated to be the principal aviation biofuel used over the short to medium term.

Meeting 2% of annual jet fuel demand from international aviation with SAF could deliver the necessary cost reduction for a self-sustaining aviation biofuel market thereafter. Meeting such a level of demand requires increased HEFA-SPK production capacity. If met entirely by new facilities, approximately 20 refineries would be required. This could entail investment in the region of $10 billion. Although significant, this is relatively small compared to fossil fuel refinery investment of $60 billion in 2017 alone.

Ongoing research and development is needed to support the commercialisation of novel advanced aviation biofuels which can unlock the potential to use agricultural residues and municipal solid wastes. These feedstocks are more abundant and generally cost less than the waste oils and animal fats commonly used by HEFA-SPK, and can therefore facilitate greater SAF production. Furthermore, synthetic fuels produced from renewable electricity, CO2 and water via Power-to-Liquid processes may offer an alternative fuel source for aviation in the long term.

Improved aviation biofuel cost competitiveness with fossil jet kerosene is also needed

SAF are currently more expensive than jet fuel, and this cost premium is a key barrier to their wider use. Fuel cost is the single largest overhead expense for airlines, accounting for 22% of direct costs on average, and covering a significant cost premium to utilise aviation biofuels is challenging.

The competitiveness of SAF depends on its production cost relative to that of fossil jet kerosene (which varies with crude oil price). For all biofuels obtaining an economic feedstock supply is fundamental to achieve competitiveness, as feedstocks are the major determinant of production costs. For HEFA-SPK economies of scale could be realised by refineries designed for continuous production.

In the long term, airlines may include SAF consumption cost premiums within ticket costs. At current prices and today’s fleet average energy efficiency, the additional cost per passenger for a 15% blend of HEFA may not be high in comparison with other elements that influence ticket prices, such as seating class, the time of ticket purchase and taxation. However, due to the competiveness of the aviation industry customer price sensitivity is a core consideration for airlines.

Policy measures are crucial to stimulate sustainable aviation fuel demand

Impressive progress has been made in the utilisation of SAF since the first biofuel flight ten years ago. However, to fulfil aviation biofuels’ potential to reduce the climate impact of growing air transport demand, further technological development and improved economics are needed.

There is a key role for policy frameworks at this crucial early phase of SAF industry development. Without a supportive policy landscape, the aviation industry is unlikely to scale up biofuel consumption to levels where costs fall and SAF become self-sustaining.

Subsidising the consumption of SAF envisaged in the SDS scenario in 2025, around 5% of total aviation jet fuel demand, would require about $6.5 billion of subsidy (based on closing a cost premium of USD 0.35 litre between HEFA-SPK and fossil jet kerosene at USD 70/bbl oil prices). This is far below the support for renewable power generation in 2017, which reached $143 billion.

Other policy measures that could support SAF market development include:

  • Financial de-risking measures for refinery project investments (e.g. grants, loan guarantees).
  • Measures to provide guaranteed SAF offtake, e.g. mandates, targets and public procurement.
  • Other mechanisms that close the cost gap between SAFs and fossil jet fuel e.g. carbon pricing.

Countries have more control over policy support for domestic than international aviation, and the introduction of national policy mechanisms to facilitate SAF consumption is gathering pace. The United States, the European Union, the Netherlands, the United Kingdom and Norway have all recently established policy mechanisms which will support the use of aviation biofuels. To gain the confidence of policy makers and the general public, such support will need to be linked to robust fuel sustainability criteria.

The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), scheduled to be introduced in 2021, will be the principal mechanism to meet the ICAO’s long-term decarbonisation targets. SAF consumption and the purchase of carbon offsets are the two principal means to achieve CORSIA compliance, with the relative attractiveness of these to the aviation industry dependent on their cost per tonne of CO2 emissions mitigated.

Gas doom hanging over Ukraine

Published

on

The long history of gas transit across independent Ukraine began with Kiev’s initial failure to pay anything for Russian natural gas, both intended for transit to Europe and for domestic consumption, on the pretext of fraternal relations between the former Soviet republics. Later it cost the Ukrainians a meager $25 for 1,000 cubic meters of Russian gas, and that ridiculously small sum remained unchanged for quite some time. The sizeable amount of Russian gas provided at a discount price, plus domestically available oil resources, were distributed by the country’s greedy elite the following way: domestically produced gas was used on utilities, proceeds from the transit of Russian gas went to the state budget (minus the money that lined bureaucratic pockets), and Russian gas – to the industry (plus the corruption component).

Then came the Ukrainian revolutions and Kiev’s desire to join “Euro-Atlantic structures” and the desire to “get off the Russian gas needle and prevent the Kremlin from using energy as a weapon.” Ukraine has tried and is still trying to believe in all this by playing up to the collective West and hoping that the West will compensate Kiev for the losses caused by its revolutionary endeavors and anti-Russian antics. As a result, we see gas prices going through the roof, an energy crisis in Europe, and the completion of the Nord Stream 2 gas pipeline.

Those in power in Kiev hoped for the very last moment that the West valued their country more than it did the energy security of European countries. Much to their surprise (and only theirs), this is not so. It looks like the Europeans are interested in Russian gas supplies and are not so eager to keep Ukraine as the main transit country. Moreover, having “democratized Ukraine” to the state of an openly anti-Russian country, the West turned it into a country, whose leadership the Kremlin does not really want to talk to simply because it does not see any point in doing this. This is the reason why third countries care (or rather pretend to care) about Ukraine. Thus, in July of this year, there came out the “Joint Statement of the United States and Germany on Support for Ukraine, European Energy Security and Our Climate Goals.” According to it, Germany pledged to do everything in its power to make sure that the agreement between Moscow and Kiev on the transit of Russian gas across Ukrainian territory was extended for up to ten years. The statement came when it was already obvious that the construction of Nord Stream 2 would be completed, Germany resisted US pressure on this issue, Moscow paid no attention and Washington, exhausted by the battles of the presidential elections and the search for new strategies in the Old World, was trying to pit America’s European friends against Russia.

It has never been a secret that the West needs reliable transit, and this is something that Ukraine also insists on. However, Kiev has officially labelled  Russia as an “aggressor country,” which means that this very “aggressor” must ensure this transit and bring billions of dollars in revenues to the Ukrainian budget. This looks like a kind of “Euro-schizophrenia” where Ukraine is an anti-Russian country and simultaneously serves as a reliable transit country for Russian gas. Things do not work this way, however, and it looks like Europeans are beginning to realize this. Therefore, most of the European consumers support Nord Stream 2 even though they do not show this in public. Suffice it to mention the recent conclusion of a years-long contract for gas supplies to Hungary.

Vladimir Putin’s statement, made amid soaring gas prices and growing threats to European industry, came as an energy lifeline for all Europeans.

“Russian President Vladimir Putin supported the initiative of Deputy Prime Minister Alexander Novak to increase gas supply on the market amid rising energy prices in Europe… Novak said that Russia can stabilize the situation with prices by providing additional volumes of gas on the exchange, adding that this country’s main priority is to accommodate domestic demand,” Lenta.ru reported.

Commenting on the possibility of increasing gas supplies via Ukraine, President Putin recalled that Ukraine’s gas transport system had not been repaired “for decades” and that “something could burst” there any time if gas pressure goes up.

“At the same time, it is more profitable and safer for Gazprom to operate new pipeline systems,” he added. Putin thus confirmed what is already clear to all that Ukraine is an unreliable and, in fact, an extra link, and that Europe can get gas bypassing technically and politically unreliable Ukrainian pipes. He also pointed out that Gazprom would suffer losses from an increase in gas transit via Ukrainian territory, while new gas pipelines offer cheaper transit options. He added that Gazprom is saving about $3 billion a year by using new pipelines and that Russia was ready to increase gas supplies and make them cheaper for European consumers.

Gas shortages have already forced the Ukrainian government to freeze gas prices for household consumers, but prices for gas for industrial enterprises are rising along with those on European exchanges, where on October 6, they reached a very impressive $ 2,000 per thousand cubic meters and went down only after Putin’s statement came out.

Meanwhile, the head of Ukraine’s Federation of Glass Industry Employers, Dmitry Oleinik, said that this [rise in gas prices – D.B.] would lead to an inevitable rise in prices. However, producers will not be able to jack up prices indefinitely, because at some point buyers simply will not be able to cover production costs.

“The Ukrainian consumer will not even be able to cover the cost of production. Plants and factories will slowly shut down and people will lose their jobs – this is already very serious. Budget revenues will “plummet,” and expenses will skyrocket… The issue of bankruptcies is just a matter of time,” Oleinik warned.

If Ukraine continues to follow the chosen course, it will face de-industrialization. By the way, this will suit the West, but certainly not the Ukrainian industrial oligarchs, who have long been eyeing agriculture, including the prospect of turning themselves into land barons. However, the farming sector will not be happy about the high prices on gas that bakeries, sugar factories and greenhouses run on. There will be nowhere to run.

Apart from purely practical realities, the conclusions I can draw from the current energy situation in the world and Vladimir Putin’s statements regarding the Ukrainian transit, are as follows:

  • Gas supplies through Ukraine and to Ukraine are not solely an economic issue, given Kiev’s endless anti-Russian escapades;
  • This problem affects the energy security of Europe;
  • Since there are several angles to this problem, it must be solved in a comprehensive manner;
  • At the same time, this cannot be done exclusively in the interests of the West and Ukraine to the detriment of the interests of Russia.

As you can see, it is once again up to Kiev and its shadow patrons to decide. And winter is just around the corner…

Russian Energy Week: Is the world ready to give up hydrocarbons?

Published

on

In an official message to mark the opening of the Russian Energy Week international forum on 13-15 October in Moscow, Russian President Vladimir Putin stressed that there are numerous issues on the agenda related to current trends in the global energy market, including improvements to industry infrastructure and the introduction of modern digital technologies into its operation.

“The efficiency of energy production and consumption is the most important factor in the growth of national economies and has a significant impact on people’s quality of life. Many countries have already adopted policies to accelerate the development of clean energy technologies,” he wrote in the message to guest and participants.

“The forum business programme is therefore set to look in detail at the possibility of developing green energy based on renewable sources and the transition to new, more environmentally friendly fuels. I am confident that the events of the Russian Energy Week will allow you to learn more about the achievements of the country’s fuel and energy sector, and that your initiatives will be put into practice,” Putin said.

Leaders of foreign states have also sent greetings to the participants and guests. For instance, President of the Republic of Angola João Manuel Gonçalves Lourenço, Prime Minister of Vietnam Pham Minh Chinh, Crown Prince of Abu Dhabi Armed Forces Mohamed bin Zayed bin Sultan Al Nahyan, and Vice Premier of the State Council of China Han Zheng.

In their greetings, it generally noted the importance of the topics to be discussed at the forum as well as the need to build an international dialogue and consolidate efforts to achieve the sustainable development goals, including as regards climate change.

The programme covers a wide range of issues of transformation and development in the global energy market. In the context of energy transition, the issues of energy development are inextricably linked with the introduction of new technologies, and the transformation aimed at reducing greenhouse gas emissions into the atmosphere. Climate protection is a task that cannot be solved by one country; it is a global goal, which can be achieved through building dialogue and cooperation between countries.

The participants in the discussion will answer the question: Is the world ready to give up hydrocarbons? In addition, during the panel session, the participants will discuss whether oil, gas and coal are really losing ground in the global energy sector; whether the infrastructure will have time to readjust for new energy sources; how long will there be enough hydrocarbons from the field projects that are being implemented; and whether an energy transition using fossil fuels is possible.

The international climate agenda is forcing many countries to reform their carbon-based energy systems. For Russia, which holds a leading position in the global hydrocarbon markets, the transition to development with low greenhouse gas emissions presents a serious challenge, but at the same time it opens up new opportunities for economic growth based on renewable energy, hydrogen technologies, advanced processing of raw materials and implementing green projects.

The Climate Agenda included sessions dedicated to the operation of the Russian fuel and energy sector in the context of energy transition, the impact of the European green pivot on the cooperation between Russia and Europe, as well as the session titled ‘The Future of Coal in a World Shaped by the Climate Agenda: The End, or a New Beginning?’

Sessions of the ‘New Scenarios for the Economy and the Market’ track are dedicated to the global challenges and opportunities of the electric power industry; the impact of ESG on the Russian fuel and energy sector; the potential for the renewable energy sources; and other issues of the future of energy.

The Russian Energy Agency under the Ministry of Energy brings together experts from key international analytical organizations to discuss the future of world energy during the session titled International Energy Organization Dialogue: Predicting the Development of Energy and Global Markets.

The Human Resource Potential of the Fuel and Energy Sector, participating experts will discuss the prospects for developing the professional qualification system, and a session titled Bringing the Woman’s Dimension to the Fuel and Energy Sector. Optimizing regulation in the energy sector and organizing the certification and exchange of carbon credits in Russia are the basis of the Regulatory Advances in Energy. 

Anton Kobyakov, Advisor to the Russian President and Executive Secretary of the Russian Energy Week 2021 Organizing Committee, said “the level of various formats of international participation testifies to the importance of the agenda and Russia’s significant role in the global energy sector. We are a reliable strategic partner that advocates for building international cooperation based on the principles of transparency and openness. With the period of major changes in the industry, it is particularly important to engage in a dialogue and work together to achieve both national and global goals.”

The forum, organized by the Roscongress Foundation, the Russian Ministry of Energy, and the Moscow Government, brought together many local and foreign energy and energy-related enterprises. The speakers attending included  Exxon Mobil Corporation Chairman of the Board of Directors and CEO Darren Woods, Daimler AG and Mercedes-Benz AG Chairman of the Board Ola Kallenius, BP CEO Bernard Looney, and TotalEnergies Chairman and CEO Patrick Pouyanné.

World Energy Outlook 2021 shows a new energy economy is emerging

Published

on

A new energy economy is emerging around the world as solar, wind, electric vehicles and other low-carbon technologies flourish. But as the pivotal moment of COP26 approaches, the IEA’s new World Energy Outlook makes it clear that this clean energy progress is still far too slow to put global emissions into sustained decline towards net zero, highlighting the need for an unmistakeable signal of ambition and action from governments in Glasgow.

At a time when policy makers are contending with the impacts of both climate change and volatile energy markets, the World Energy Outlook 2021 (WEO-2021) is designed as a handbook for the COP26 Climate Change Conference in Glasgow, which offers a critical opportunity to accelerate climate action and the clean energy transition. The new analysis – which the IEA is making available for free online – delivers stark warnings about the direction in which today’s policy settings are taking the world. But it also provides clear-headed analysis of how to move in a well-managed way towards a pathway that would have a good chance of limiting global warming to 1.5 °C and avoiding the worst effects of climate change.

The WEO-2021, the IEA’s annual flagship publication, shows that even as deployments of solar and wind go from strength to strength, the world’s consumption of coal is growing strongly this year, pushing carbon dioxide (CO2) emissions towards their second largest annual increase in history.

“The world’s hugely encouraging clean energy momentum is running up against the stubborn incumbency of fossil fuels in our energy systems,” said Fatih Birol, the IEA Executive Director. “Governments need to resolve this at COP26 by giving a clear and unmistakeable signal that they are committed to rapidly scaling up the clean and resilient technologies of the future. The social and economic benefits of accelerating clean energy transitions are huge, and the costs of inaction are immense.”

The WEO-2021 spells out clearly what is at stake: what the pledges to reduce emissions made by governments so far mean for the energy sector and the climate. And it sets out what needs to be done to move beyond these announced pledges towards a trajectory that would reach net zero emissions globally by mid-century – the Net Zero Emissions by 2050 Scenario from the landmark IEA report published in May, which is consistent with limiting global warming to 1.5 °C.

As well as the Net Zero Emissions by 2050 Scenario, the WEO-2021 explores two other scenarios to gain insights into how the global energy sector may develop over the next three decades – and what the implications would be. The Stated Policies Scenario represents a path based on the energy and climate measures governments have actually put in place to date, as well as specific policy initiatives that are under development. In this scenario, almost all of the net growth in energy demand through 2050 is met by low emissions sources, but that leaves annual emissions still around today’s levels. As a result, global average temperatures are still rising when they hit 2.6 °C above pre-industrial levels in 2100.

The Announced Pledges Scenario maps out a path in which the net zero emissions pledges announced by governments so far are implemented in time and in full. In this scenario, demand for fossil fuels peaks by 2025, and global CO2 emissions fall by 40% by 2050. All sectors see a decline, with the electricity sector delivering by far the largest. The global average temperature rise in 2100 is held to around 2.1 °C.

For the first time in a WEO, oil demand goes into eventual decline in all the scenarios examined, although the timing and speed of the drop vary widely. If all today’s announced climate pledges are met, the world would still be consuming 75 million oil barrels per day by 2050 – down from around 100 million today – but that plummets to 25 million in the Net Zero Emissions by 2050 Scenario. Natural gas demand increases in all scenarios over the next five years, but there are sharp divergences after this.

After decades of growth, the prospects for coal power go downhill in the Announced Pledges Scenario – a decline that could be accelerated further by China’s recent announcement of an end to its support for building coal plants abroad. That move may result in the cancellation of planned projects that would save some 20 billion tonnes in cumulative CO2 emissions through 2050 – an amount similar to the total emissions savings from the European Union reaching net zero by 2050.

The differences between the outcomes in the Announced Pledges Scenario and the Net Zero Emissions by 2050 Scenario are stark, highlighting the need for more ambitious commitments if the world is to reach net zero by mid-century.

“Today’s climate pledges would result in only 20% of the emissions reductions by 2030 that are necessary to put the world on a path towards net zero by 2050,” Dr Birol said. “Reaching that path requires investment in clean energy projects and infrastructure to more than triple over the next decade. Some 70% of that additional spending needs to happen in emerging and developing economies, where financing is scarce and capital remains up to seven times more expensive than in advanced economies.”

Insufficient investment is contributing to uncertainty over the future. Spending on oil and natural gas has been depressed by price collapses in 2014-15 and again in 2020. As a result, it is geared towards a world of stagnant or even falling demand. At the same time, spending on clean energy transitions is far below what would be required to meet future needs in a sustainable way.

“There is a looming risk of more turbulence for global energy markets,” Dr Birol said. “We are not investing enough to meet future energy needs, and the uncertainties are setting the stage for a volatile period ahead. The way to address this mismatch is clear – a major boost in clean energy investment, across all technologies and all markets. But this needs to happen quickly.”

The report stresses that the extra investment to reach net zero by 2050 is less burdensome than it might appear. More than 40% of the required emissions reductions would come from measures that pay for themselves, such as improving efficiency, limiting gas leakage, or installing wind or solar in places where they are now the most competitive electricity generation technologies.

These investments also create huge economic opportunities. Successfully pursuing net zero would create a market for wind turbines, solar panels, lithium-ion batteries, electrolysers and fuel cells of well over USD 1 trillion a year by 2050, comparable in size to the current oil market. Even in a much more electrified energy system, major opportunities remain for fuel suppliers to produce and deliver low-carbon gases. Just in the Announced Pledges Scenario, an additional 13 million workers would be employed in clean energy and related sectors by 2030, while that number doubles in the Net Zero Emissions by 2050 Scenario.
