Energy Storage

Indian renewable energy developer Greenko Group has partnered with Belgium’s John Cockerill to develop a green hydrogen electrolyzer factory with a capacity of 2GW per annum.  The partnership will also see the two companies jointly develop large-scale green hydrogen projects in India.

A new report by JMK Research and the Institute for Energy Economics and Financial Analysis (IEEFA) says India is likely to miss its ‘100GW by 2022’ solar target by about 27GW, mainly due to the underwhelming growth of rooftop solar. While utility-scale solar is on track to achieve nearly 97% of the 60GW installed capacity targeted by 2022, rooftop solar will be 25GW short of the 40GW mark.

Based in Gurugram, the plant will produce customized lithium battery packs for electric vehicles and stationary energy storage applications, including solar. The production capacity will be scaled up to 200MWh/annum by December end.

Swiss Clean Battery is set to start commercial production of its pure solid state batteries in Switzerland. The batteries are based on a protected electrolyte made of a solid ion conductor, which helps to maintain internal resistance and capacity. The fixed ion conductor is formed in the battery cell itself, similar to a multi-component adhesive.

The global battery energy storage market will grow to $10.84 billion in 2026, with around two-thirds of the demand concentrated in the Asia Pacific region. 

Bosch’s new solid oxide fuel cell prototype has an electrical efficiency of more than 60% and an overall efficiency above 85%. It also has a targeted power output of 10 kW and can produce up to 3 kW of thermal energy.

The agreement will see Powin supply and commission its advanced Stacks battery storage product lines for round-the-clock renewable energy projects undertaken by O2 Power.

US scientists have developed a battery that can retain 92% of its initial capacity over periods of 12 weeks, with a theoretical energy density of 260 W/hour per kg. It was built with an aluminum anode and a nickel cathode, immersed in molten-salt electrolyte.

Japanese investor Mitsui has signed the agreement to raise a 49% stake in ReNew Power’s 1.3GW hybrid renewable energy project supplemented with up to 100MWh of battery storage. The project will supply 400MW of round-the-clock power to the Solar Energy Corporation of India (SECI) under a 25-year power purchase agreement.

Germany’s Ostermeier H2ydrogen Solutions has developed an electrolyzer that works with tap water, with bottles to store hydrogen and a fuel cell or a Wankel engine to produce electricity. The system has a capacity ranging from 1kW to 100 kW, which corresponds to hydrogen production of 0.2-20 Nm3/h.
