On the occasion of the 10th Clean Energy Ministerial and 4th Mission Innovation Ministerial, a new international partnership has been established to help expand the deployment of energy storage and bring new technologies to developing countries’ power systems. The Energy Storage Partnership (ESP) comprises the World Bank Group and 29 organizations working together to help develop energy storage solutions tailored to the needs of developing countries.

Energy transitions are underway in many countries with a significant increase in the use of wind and solar power. To integrate these variable renewable resources into grids at the scale necessary to mitigate climate change, energy storage will be key. The increased use of wind and solar power with storage can help decarbonize power systems; expand energy access; improve grid reliability; and increase energy systems’ resilience.

The requirements of developing countries’ grids are not yet fully considered in the current energy storage market – even though these countries may have the largest potential for battery deployment. The current battery market is driven by the electric vehicle industry and most mainstream technologies cannot provide long duration storage or withstand harsh climatic conditions and low operation and maintenance capacity.

There is a clear need to catalyze a new market for batteries and other energy storage solutions that are suitable for electricity grids for a variety of grid and off-grid applications and deployable on a large scale. To enable the rapid uptake of variable renewable energy in developing countries, the WBG is convening an Energy Storage Partnership (ESP) that will foster international cooperation on:

  • Technology Research Development & Demonstration, Applications
  • System Integration and Planning Tools
  • Policies, Regulations and Procurement
  • Enabling Systems for Management and Sustainability

By connecting stakeholders and sharing international experiences in deploying energy storage solutions, the ESP will help bring new technological and regulatory solutions to developing countries, as well as help develop new business models that leverage the full range of services that storage can provide. The ESP will take a holistic, technology-neutral approach by including all forms of energy storage, including batteries. The ESP will help expand the global market for energy storage, leading to technology improvements and accelerating cost reductions over time.

“The fast growth we’re seeing in the electric vehicle market is exactly what we need for energy storage in power systems around the world. We want to see batteries connected to the grid, serving mini-grids, and enabling much more use of renewable power from the sun and wind,” said Riccardo Puliti, Senior Director for Energy and Extractives, World Bank. “This is why we are convening the Energy Storage Partnership and we are honored to work with the partners who have joined this initiative. We’re looking forward to having more partners join the effort.”

Mission Innovation was born out of a global commitment to accelerate clean energy innovation, to make clean energy widely affordable and accessible. We recognize that this cannot be done by Mission Innovation alone and that we need strong partnerships with organizations like the World Bank to be successful,” said Frank Des Rosiers, Chair of the Mission Innovation Steering Committee. “This Energy Storage Partnership with the World Bank aligns with a key innovation opportunity that Mission Innovation members have identified through our Smart Grid Innovation Challenge.”

Power systems are undergoing rapid change. Policy makers and regulators need to actively identify options to increase the flexibility of power systems in their jurisdictions; this not least to accommodate the integration of increasingly larger shares of intermittent renewable generation and distributed energy resources,” said Christian Zinglersen, Head of Secretariat, Clean Energy Ministerial. “This is the focus of several areas of CEM work where storage is an area of increasing interest amongst CEM governments and other partners. Policy and regulatory design will remain key in order for storage-based solutions to contribute cost efficiently to the needs of a changing power mix. Hence, partnerships such as this targeting real-world, deployable solutions are very valuable.”

The ESP will be hosted at the World Bank’s Energy Sector Management Assistance Program (ESMAP) and will be developed and implemented in partnership with other organizations. The ESP will complement the WBG’s  $1 billion battery storage investment program announced in September 2018 to significantly scale up support to battery storage projects and raise an additional $1 billion in concessional finance.

Energy efficiencies of EU waste incinerators are appallingly low

A new study published today by Zero Waste Europe (ZWE) finds that efficiences of electricity generation of existing EU waste incineration facilities are appallingly low.

The study “Debunking Efficient Recovery: the Performance of EU Incineration Facilities” done by Equanimator found that typical efficiencies of generation of energy, especially when generating electricity only, are around the mid-20’s % in the best cases. This compares poorly with the figures of around 35% for coal-fired electricity generation, and 55% for combined cycle gas turbine (CCGT) plants. 

The situation is somewhat better, comparatively, as regards heat generation, but even here, performance is no better than that of domestic gas-fired boilers. The situation worsens – the emissions effectively double, both for electricity and for gas – when emissions of non-fossil CO2 from waste incineration are considered.

Moreover, the study questions the rather arbitrary basis for distinguishing between disposal (D10) and recovery (R1) incineration. The energy efficiency threshold set under the R1 formula that was established to draw a distinction between waste disposal and recovery incinerators is one which is far too easily met. The R1 threshold could be achieved at efficiencies of as low as 16.5% net efficiency. The report thus recommends abandoning the meaningless distinction between D10 and R1 incineration. 

Janek Vähk, ZWE’s Climate, Energy, and Air Pollution Programme Coordinator, says: “The report provides evidence that burning waste for energy is a very inefficient process and as such the energy recovery aspect of it is often overemphasised by some stakeholders. Moreover, the ongoing decarbonisation makes it increasingly difficult to consider waste as a suitable source of energy, thus the need to recover energy from waste which led to the R1 formula is outdated.“

Dominic Hogg, Director of Equanimator: “The case for distinguishing between ‘recovery’ and ‘disposal’ on grounds of energy efficiency is always questionable. Incinerators are required, by law, to recover heat as far as is practicable, and any meaningful distinction would have excluded a significant proportion of operating facilities. Instead, according to EU data, some 98% of all municipal waste incinerated is dealt with at facilities that qualify as ‘recovery’. That suggests the ‘efficiency threshold’ has been designed to be too easily met. Given the diminishing benefits from incineration as energy systems decarbonise, it’s time to dispose of this distinction, and reclassify all incinerators as disposal facilities.”

The low generation efficiency of incineration leads to greenhouse gas emissions per unit of electricity are almost double of those associated with natural gas generation.

With the above in mind, ZWE calls on the European Commission in the upcoming revision of the Waste Framework Directive:

  • to remove the R1 formula in Annex II of the Waste Framework Directive so that municipal waste incineration is no longer able to be classified as ‘recovery’;
  • establish a mixed (residual) municipal waste generation target of 100 kgs per capita by 2035, to shift the focus from the disposal of waste to addressing the mixed waste generation in the first place.

Offshore wind farms move ahead full sail with underwater help

By MICHAEL ALLEN

Off the coast of Portugal, a team of underwater robots is scanning the base of turbines on a wind farm and looking for signs of damage while aerial drones check the blades. The activity is part of a project to reduce inspection costs, keep wind turbines running for longer and, ultimately, reduce the price of electricity.

Wind power accounted for more than a third of the electricity generated from renewable sources in the EU in 2020 and offshore wind energy is expected to make a growing contribution over the coming years. Denmark became home of the world’s first offshore wind farm in 1991 and Europe is a global leader in the field.

Still, running wind farms in seas and oceans is expensive and adds to the overall cost of such clean power. Furthermore, Asian companies in the sector are gaining ground, increasing the European industry’s need to retain a competitive edge.

Lower costs

‘Up to 30% of all operation costs are related to inspection and maintenance,’ said João Marques of the INESC TEC research association in Portugal.

Much of this comes from sending maintenance crews out in boats to examine and repair offshore-wind infrastructure.

The EU-funded ATLANTIS project is exploring how robots can help on this front. The ultimate goal is to cut the cost of wind energy.

Underwater machines, vehicles that travel on the water surface and aerial drones are just some of the robots being tested. They use a combination of technologies – such as visual and non-visual imaging – and sonar to inspect the infrastructure. Infrared imaging, for instance, can identify cracks in turbine blades.

Research carried out by the project suggests that robotics-based technologies could increase the amount of time that maintenance vessels can work on wind farms by around 35%.

Higher safety

Expense is not the only consideration.

‘We also have some safety concerns,’ said Marques, who is a senior researcher on the ATLANTIS project.

Having people transfer from boat to turbine platforms, dive beneath the waves to inspect anchor points and scale turbine towers is dangerous.

It is safe for people to transfer from boats to turbine platforms only when waves are less than 1.5 metres high. By contrast, robotic inspection and maintenance systems can be deployed from boats in seas with waves of up to 2 metres.

In addition, easier and safer maintenance will increase the amount of time that wind farms can be fully operational. In winter, it is often impossible to carry out offshore inspection and maintenance, which must wait for better weather in spring or summer.

‘If you have a problem on a wind farm or on a particular turbine in a month where you cannot access it, it needs to be stopped until someone can reach it,’ said Marques.

Being able to work in higher waves means that causes of wind-farm shutdowns can be tackled more quickly.

First of its kind

The project’s test site is based on a real offshore wind farm in the Atlantic Ocean, 20 kilometres from the northern Portuguese city of Viana do Castelo. It is the first of its kind in Europe.

‘We need somewhere to actually test these things – somewhere where people can actually develop their own robotics,’ Marques said.

In addition to its own robotic technologies, ATLANTIS aims to help other research teams and companies develop their own such systems.

European researchers and businesses active in this cutting-edge sector should be able to book time to use the facilities starting early this year.

Damage prevention

Another way to cut maintenance costs is reducing damage and the need for repairs in the first place. The recently concluded EU-funded FarmConners project sought to do just that through the widespread use of a technology called wind farm control, or WFC.

When hit by wind, a turbine extracts energy from the air flow. As a result, the flow behind the turbine has a reduced energy, a phenomenon known as shadowing. Because of this uneven distribution of energetic load on blades and towers, some turbines get damaged more than others.

WFC aims to balance out the distribution of wind energy throughout the farm, according to project co-coordinator Tuhfe Göçmen of the Technical University of Denmark.

There are several ways to mitigate the effects of shadowing. One is to misalign turbines. Instead of facing straight into the wind, a turbine can be turned slightly so that the shadow effect is steered away from turbines behind.

The pitch and the rotational speed of the turbine’s three blades can also be changed. While this cuts the amount of energy the turbine produces, it leaves more for the turbines behind to harvest.

Grid-friendly

As well as reducing wear and tear and maintenance costs, WFC can make wind farms more productive and help them generate power in a way that is easier for the electricity grid to handle.

Renewable energy including wind power is often produced in peaks and troughs. Sometimes the peaks, or surges in power, can overload the electricity grid.

With the turbines working together, power production can be levelled out to provide more consistent and stable input to the grid, according to Göçmen.

‘If we control turbines collectively, it is simply more efficient,’ he said.

Research has shown that such wind-farm control could increase the power output of all wind farms in the EU by 1%.

That’s equivalent to twice the output of a 400 megawatt wind farm, which would cost around €1.2 billon to build, according to Gregor Giebel, a FarmConners co-coordinator also at the Technical University of Denmark.

This technology is also simple to implement as most wind turbines can be controlled and adjusted to act in the ways needed by WFC. The wind farms need simply to update their control software.

There is a lot of commercial interest in WFC technology, making it a promising way for Europe to expand its use of wind energy, according to Göçmen,

It is ‘low-cost and potentially high-gain,’ he said.

Green Energy and Global Integration Will Sustain Positive Economic Outlook

Published

Recent economic signals have given experts reasons for hope, if not complacency about the outlook for 2023. Signs of declining inflation, resilient consumer spending and strong labour markets, among others, suggest that growth could be rebounding in the short term.

“My message is that it is less bad than we feared a couple of months ago, but that doesn’t quite get to us to being good,” said Kristalina Georgieva, Managing Director of the International Monetary Fund.

The threat of rising inflation seems to have abated in many parts of the world, thanks in part to interest rate increases from some central banks. While many decision-makers have expressed determination to sustain rates, there is a risk that recent improvements could cause leaders to ease rates.

“The greatest tragedy in this moment would be if central banks were to lurch away from a focus on assuring price stability prematurely and we were to have to fight this battle twice,” said Lawrence H. Summers, Professor at Harvard Kennedy School of Government.

A major economic priority worldwide for 2023 involves accelerating decarbonization. Recent legislation in the United States to support green energy will provide billions of dollars in funding but has provoked concerns of launching a subsidy war between Europe and the US over decarbonization technology. On the one hand, competition to promote green energy could accelerate progress for the benefit of all. On the other hand, the risks that nations will block technological developments and turn inward would deter global progress.

“I hope very much that this subsidy race we are hearing about is not going to be a race for the bottom,” said Christine Lagarde, President of the European Central Bank. A negative repercussion of Europe-US competition would be overlooking the imperative to finance the green energy transformation in the developing world, which is the most vulnerable to the impacts of the climate crisis.

Competition over green energy could amplify other risks of fragmentation in global trade as many nations prioritize national security over global integration. “Over the last three years, we have entered a new era of globalization. We have shifted from market-driven globalization to politically powered globalization,” said Bruno Le Maire, France’s Minister of Economy, Finance and Industrial and Digital Sovereignty.

Fragmentation poses numerous risks to the world economy, such as higher costs associated with reorganizing supply chains. For example, Europe and the US have focused recently on increasing domestic production of silicon chips. There is a risk that such turning inward will impede global cooperation on trade and climate goals.

The easing of pandemic restrictions in China raises questions for the 2023 economic outlook. One potential concern involves rising energy costs worldwide, as Chinese consumption rises.

In Japan, inflation remains a concern, but the nation has seen recent improvements in job creation. “We made that change I should say mainly due to increased labour participation of women,” said Kuroda Haruhiko, Governor of the Bank of Japan.

In terms of the most pressing risks for 2023, economic experts focused on the ongoing war in Ukraine not only as a geopolitical and humanitarian crisis but also as a concern for economies around the world. Likewise, experts expressed uncertainty about whether inflation would continue a downward trajectory and about the continued threat of mutations of COVID-19. Despite recent signs of improvement, “relief must not become complacency,” Summers noted.
