ESS eyes African power market for all-iron flow batteries

All-iron flow battery system manufacturer Energy Storage Systems (ESS) has outlined plans to expand into the African market, targeting microgrid and utility-scale projects.

Oregon-based ESS has become the first flow battery manufacturer to join the US-backed Power Africa programme, which works with governments, agencies and private companies to develop power-generating infrastructure in electricity-starved sub-Saharan Africa.

South Australia in new Tesla deal for home batteries

South Australia has done a fresh batteries deal with Tesla— this time to provide the US firm’s Powerwall 2 units free to up to 50,000 homes to create the “world’s largest virtual power plant”.

The state government will provide one of the 13.5kWh lithium-ion batteries to each home as part of the solar-energy storage project.

New Jersey adds zinc hybrid battery to microgrid

New Jersey energy utility PSE&G has installed a 250kW/1MWh Eos Aurora battery system, using zinc hybrid cathode technology, for a solar microgrid project.

The zinc hybrid battery system, developed by US firm Eos Energy Storage, has been deployed at a wastewater treatment plant— to act as “a central component” of PSE&G’s on-site solar-plus-storage microgrid to keep the facility running during extended power outages.
