Energy Storage

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.

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.

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.

While electric companies in the Global North wrestle with how to keep the lights on as ever bigger solar and wind park capacities come online, developing-world utilities are experimenting with new ways of working and transforming the relationship between themselves and millions of new customers.

A US-Mexican research team has investigated how linking heat pumps with solar thermal collectors may help reduce the surface needed to deploy the collectors themselves. The scientists found the proposed solution may not only significantly reduce the footprint of solar thermal systems but also provide a lower levelized cost of energy compared to fossil fuels.

Anda-Olsen launched new LiFePo4 batteries that come with a built-in heating elements that reportedly makes them safe to use even in freezing temperatures. The manufacturer offers the new product in two versions with a nominal capacity of 100 Ah and 200 Ah, respectively.
