Energy Storage

Altech Batteries, a battery tech company in Western Australia, has included “game-changing” sodium chloride technology in its new battery 1 MWh GridPack. It said it expects the new systems to be up to 40% cheaper to produce than dominant lithium-ion alternatives.

Storage specialist Fluence has launched Ultrastack, a battery energy storage system (BESS) for storage-as-transmission assets (SATA). It is designed to help network owners and operators to manage renewables curtailment, increase the use of power lines, and limit congestion.

RWE has revealed that it has received alkaline electrolyzers from Sunfire for a pilot project in Germany, while the European authorities have reached a deal on the continent’s renewable energy directive.

Property developer Steenoven and an undisclosed construction contractor have started drilling a borehole for a new thermal energy storage system in the historic city of Bruges, Belgium.

Much has been said about the benefits installing solar and batteries can offer to businesses but, as companies face mounting input cost inflation, is the upfront investment too much to bear or have volatile electricity costs made the decision a no-brainer?

Australian battery manufacturer Redflow has signed a deal that will see it supply its “non-lithium” energy storage technology to clean energy outfit Ameresco which is looking to develop integrated solar and zinc-bromine flow battery solutions for its customer base throughout North America and Europe.

While it initially had a chilling effect on the Polish residential solar market, the transition from net metering to net billing has also resulted in positive changes, such as better sizing of rooftop PV systems and a higher rate of self-consumption, says Instytut Energetyki Odnawialnej (IEO), a Polish research body.

iDM has developed a modular air-source heat pump that uses propane (R290) as the refrigerant. It can produce between 2 kW and 24 kW of heat and domestic hot water up to a temperature of 70 C. A larger version can produce between 10 kW and 50 kW of heat.

The International Renewable Energy Agency (IRENA) told Berlin Energy Transition Dialogue participants this week that $5.4 trillion of annual investment is needed to support the global shift to renewables. Kenyan President William Ruto, meanwhile, called for a fair energy partnership between Europe and Africa.

The minigrid space continues to attract a lot of attention from development partners in Africa. Minigrids can actually generate profits, so there is no doubt that commercial finance players will eventually jump on the bandwagon, according to the Africa Solar Industry Association (AFSIA).
