Softbank Group’s SB Energy subsidiary is among investors that contributed to a successful US$30 million Series C funding round for ESS Inc, a US-headquartered manufacturer of iron flow batteries that use a proprietary saltwater electrolyte.
At 4:52pm on Friday 9 August 2019, the UK suffered its first wide-scale blackout in more than a decade. More than 1.1 million consumers were plunged into the dark as rail lines screeched to a halt, traffic lights failed and even airports reported problems. Liam Stoker looks at the root causes, and how battery storage came to the rescue.
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.
Approval has been given to the compliance plans of two more US RTOs and ISOs to be filed under FERC Order 841, the ruling set by the US Federal Energy Regulatory Commission (FERC) designed to open up regional grid operators’ wholesale markets to electricity storage.
The Nobel Foundation recognised not only the role of lightweight, portable battery technology for mobile phones, laptops and latterly electric vehicles, but also that it “can also store significant amounts of energy from solar and wind power, making possible a fossil fuel-free society”.
Batteries are increasingly widely used in grid balancing, but there are many more applications where a battery can play an important role. With electric grids requiring periodic maintenance, batteries can stand in for the grid during downtime in order to reduce the impact on industry and households, writes Dieter Castelein.
British battery storage system manufacturer Powervault is backing a recent agreement with energy tech platform Kaluza to help expand its reach in its home market.
Inverter manufacturer Sungrow, which is rapidly becoming also known for its energy storage systems (ESS), will be supplier for Stem Inc.’s forthcoming large-scale solar-plus-storage projects in Massachusetts.
New technologies and designs aimed at driving down the cost of energy storage facilities are currently the focus of intense industry R&D. Sara Verbruggen reports on DC coupling, an emerging system architecture that many believe will soon become the industry standard.
Reports of Eos’ aqueous zinc battery being paired with small modular nuclear reactors (SMNRs) in a joint venture (JV) with Holtec appear to have been greatly exaggerated, according to an Eos representative.
