Energy Storage

There has been significant progress in the decarbonization of the electricity supply in Great Britain in recent years, underscored by a record run of 19 days of zero coal generation in May and June 2019. With National Grid’s stated aim of operating a carbon-neutral electricity system by 2025, the co-location of PV with battery storage could play a key role. The proposition offers the twin benefits of enabling increasingly high renewables penetration while simultaneously improving network stability. Adam Sharpe of Everoze explores the role of co-located PV and energy storage assets within the context of the UK’s future decarbonization plans.

The European Commission has approved state aid for the so-called European Battery Alliance to promote the development of a lithium-ion battery supply chain in the European Union.

As part of a series of interviews on renewable energy and geopolitics, Indra Overland – head of the Center for Energy Research at the Norwegian Institute for International Affairs – explains why some countries will take the lead in the energy transition. All of the countries in Africa, with the exception of a few oil exporters, will be part of the solar revolution, he said, noting the recent release of the GeGaLo Index. He also looks at why big economies such as the United States, Germany, China and Australia are not geopolitically well-situated for the energy transition, and why others, such as Japan, France and Spain, are positioned more favorably. In addition, Overland discusses why it is particularly important that nations under strong political pressure grasp the benefits of clean energy.

Greece’s largest international airport has set a goal to operate as a net zero carbon emitter by 2025, mainly via investing in on-site solar. Should the goal be met, the airport will be Europe’s first to rely on self-generated electricity and operate with net zero emissions.

The combination of pumped hydro with other storage technologies can increase renewables penetration, improve operational safety and reduce maintenance costs at large-scale hydropower plants, according to new research. The study also focuses on techniques to determine the optimal size of renewables-based pumped hydro storage systems. Costs for hybrid solar-pumped hydro projects currently range from $0.098/kWh to $1.36/kWh.

Mali is set to host one of the world’s largest off grid solar+storage projects, as a 30 MW solar plant will soon be coupled with a 17MW/15MWh storage facility to power the Fekola gold mine. Finland’s Wärtsilä will supply the battery.

Ofgem passed its long-awaited, controversial plan for network charges last week, despite earlier warnings against the move. The UK electricity market regulator’s Targeted Charging Review has provoked a backlash in the renewables sector, as many believe that the plan will damage the economics of distributed energy resources and unsubsidized onshore wind and solar development.

The project is an extension of the Hélio Boulouparis 1 installation, which was commissioned in May 2017 with 11.2 MW of capacity.

The project was realized by the i-DE distribution company of the Spanish electric utility. The large scale storage battery is intended to improve the quality of electricity supply with a focus on solar projects located nearby.
