Energy Storage

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.

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 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.

Sao Paulo-based Clean Energy Latin America says green hydrogen could be produced in Brazil at a levelized cost of hydrogen (LCoH) of $2.87 and $3.56 per kg in some strategic locations.

Researchers in China have summarized the technical issues hindering the development of hard carbon, which is regarded as the most promising anode for high-performance, commercial sodium-ion batteries.

Carrier, a US-based heating solutions provider, has introduced a new line of high-temperature heat pumps with capacities ranging from 30 kW to 735 kW, with hydrofluoroolefins as a refrigerant.
