The potential for storage to help stabilise the grid has finally been recognised in the UK, where battery projects took all of the 200MW on offer in a recent frequency response tender. David Pickup looks at the evolving role of storage in the future grid and how further policy support can help it flourish.
The complexities of combining batteries and solar microgrids are explained by Sam Duby, who is co-founder and director of research and development at mini-grid technologies company SteamaCo Ltd and consults for TFE Consulting. TFE Consulting is a strategy consulting firm focusing on accelerating the energy transition in emerging markets and is active in Africa, India, Southeast Asia and Latin America.
The remote microgrid market is maturing regarding technology and financing. Now improved sales and marketing methods are needed to commercialise the huge potential on offer in this burgeoning market segment, writes Thomas Hillig.
Japan-headquartered NGK Insulators is the manufacturer of the NAS sodium sulfur battery, used in grid-scale energy storage systems around the world.
While Brexit – the impending departure of the UK from the European Union – looms, bringing uncertainty into the country’s economy and international relationships, the role energy storage will play in a decentralised, low(er) carbon and more flexible energy system at least seems a little more assured than it did before.
Increasing Li-ion demand will help to continue to lower energy storage costs, but also brings up an important issue: what should be done with the batteries after they are used in vehicles? Chris Robinson of Lux Research weighs up the pros and cons of recycling versus repurposing for second-life use.
To date, the vast majority of the entries into the energy storage market have depended on lithium-based battery chemistry, but, the idea that lithium-ion is the technological and economic front-runner in the stationary storage space is a myth that is in dire need of de-bunking, claims Ron Van Dell.
