Utility Scale Storage

Stryten Energy is planning to begin commercializing its vanadium redox flow batteries in January 2025. Meanwhile it has deployed a 20 kW/120 kWh pilot-sized version of the storage system at a facility operated by Snapping Shoals EMC, an electricity cooperative in Georgia, United States.

H2FLY claims that a recent three-hour test flight, entirely powered by liquid hydrogen, could lead to sustainable long-range flights fueled by liquefied, cryogenic hydrogen. Solaris, meanwhile, has started selling hydrogen buses in Italy.

With battery storage such a crucial aspect of the energy transition, lithium-ion (li-ion) batteries are frequently referenced but what is the difference between NMC (nickel-manganese-cobalt), LFP (lithium ferro-phosphate), and LTO (lithium-titanium-oxide) devices and their underlying chemistry?

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%.

Researchers found out that the cheapest way to reach a net-zero system in Europe includes a power grid expansion and a hydrogen network. Meanwhile, Lhyfe signs a PPA for its hydrogen facility in Bretagne, and Nortegas reaches 15% of hydrogen in replica of its distribution network in Spain.

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%.

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 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.

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.

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.
