Closed-loop pumped hydro energy storage (PHES) has fewer emissions associated with its development, construction and use than other leading options for large-scale energy storage.

More news in brief from around the world in energy storage, featuring vanadium redox flow batteries (VRFBs), bankruptcy for a thermal storage startup and a new integrated lithium tech.

News in brief from around the world in energy storage.

Study conducted by the Massachusetts Institute of Technology Energy Initiative has found energy storage can be a key enabler for the clean energy transition.  

Andy Colthorpe speaks to Maria Skyllas-Kazacos, one of the original inventors of the vanadium redox flow battery, about the origins of the technology and its progression.

As energy system modernisation and decarbonisation progresses, energy storage could represent between 10% and 25% of India’s total installed power capacity by 2050, while other countries in South Asia including Bangladesh, Nepal and Bhutan also have “significant opportunities” for energy storage.

The rapid acceleration in energy storage deployment expected over the coming years will require innovation in the quality and safety standards underpinning new battery and associated technologies. VDE’s Jan Geder looks at the technical work underway to ensure the coming storage boom has firm bankability and insurability foundations.

A study co-written by industry figures has put forward new claims of the cost-competitiveness of European solar-plus-storage, amid predictions that grid parity will unfold continent-wide by 2025.

The UK’s power system could become greener and more efficient if excess generation, typically from renewable sources, was used to create hydrogen, a national association of engineers has said.

While energy storage can be considered “critical” to Australia’s transformation to a distributed, low carbon energy mix, a lack of investment and planning for the technology could have negative consequences for the network.
