High-energy, membrane-free organic redox flow battery
US researchers have developed a new high-voltage, membrane-free, nonaqueous lithium-based organic redox flow battery. They say that the elimination of the membrane decreases the upfront costs of the battery by as much as 30%.
Shell looking to sell Sonnen
Shell, which acquired Sonnen four years ago, is now actively seeking a majority shareholder for the Germany storage system specialist.
Distributed PV, battery storage curtailment in low-voltage networks
University of New South Wales (UNSW) researchers have looked at energy losses in South Australia and have identified average curtailment of 1.5% for distributed PV sites and 0.2% for distributed PV coupled with batteries, but some locations experience generation losses of up to 25%.
PV-powered heat pumps with thermal, electrical storage
Italian researchers have looked at the potential of thermal and electrical energy storage to improve self-consumption rates in buildings when coupled with PV-powered heat pumps. They have concluded that such an approach could yield self-consumption rates of more than 80%.
EnerVenue launches new metal-hydrogen battery variant
EnerVenue has developed a new metal-hydrogen battery. The US startup says the battery’s efficiency ranges from 80% to 90%, depending on the cycle rate, and claims that its energy density per square foot is equal to or even better than lithium-ion batteries.
India approves viability gap funding scheme for battery storage development
India aims to develop 4 GWh of battery energy storage systems (BESS) by 2030-31 through its viability gap funding (VGF) scheme. The selection of BESS developers for VGF grants will undergo a transparent, competitive bidding process.
Anode-less redox flow batteries capable of fast cycling
Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm−2, without short circuit or voltage instability.
Coremax unveils 100Ah lithium iron phosphate for rooftop PV
The Chinese manufacturer said its new storage system is intended for use in residential and small commercial PV systems. It features a storage capacity of 30 kWh and a nominal voltage of 51.2 V.
Akuo to deploy 200 MWh of battery storage in New Caledonia
Akuo plans to deploy 200 MWh of battery storage in New Caledonia, supplying 50 MW for three hours per day over 12 years. The facility will primarily support the operation of nickel mines.
Israel’s Teralight secures 23-year PPA for 108 MW/433 MWh of solar, storage
Teralight has signed a 23-year power purchase agreement (PPA) for 108 MW/433 MWh of solar-plus-storage capacity. It will sell electricity to Dalia Power Energies under a tariff linked to the Israeli Electricity Authority’s regulated production tariffs.
