Starting from this year, the scheme will also be open to green hydrogen facilities that are directly linked to wind or solar parks, and industrial electrification projects based on hybrid glass furnaces.

Vattenfall, SSAB and LKAB have reached the halfway point in the construction of a rock cavern storage facility in a coastal city in northern Sweden. The 100-cubic-meter facility is being constructed 30 meters below ground and will begin storing green hydrogen next year.

An international research group has developed a solid oxide fuel cell that may be used in vehicles. The monolith device has an active cell area of around 18 cm2 and was built through common manufacturing processes. It was found to achieve a high power density of 5.6 kW/L, which the scientists said is comparable with that of the best performing fuel cells based on ceramic anodes.

Australia’s biggest power producer AGL has secured planning approval for a 500MW/2GWh grid-connected utility scale battery to be developed at the site of its coal-fired Liddell power plant in the New South Wales Hunter Valley.

A Dutch-Danish research group has provided a proof of concept for the use of Blatter radicals in electrochemical energy-storage applications. It tested these compounds in a small electrochemical cell that was found to remain stable over 275 charge/discharge cycles.

According to the new provisions introduced by the French government, owners of PV systems with a capacity of up to 500 kW will pay a grid fee that is 40% of the current rate. As for heat pumps, their owners will pay only 20% of the fee.

According to a study by CELA Clean Energy Latin America, there are currently approximately 10.7 GW of solar photovoltaic and wind projects under bilateral PPAs in the Latin American country.

Researchers in Sweden are currently testing three kinds of coatings — hydrophobic, superhydrophobic and slippery liquid-infused porous surfaces. The goal of the new technology is to halve ice adhesion compared to standard modular glass and ensure 96% light transmittance.

The agrivoltaic facility may have a capacity of 1 to 3 MW and will have to be designed to comply with landscape requirements and the agricultural practices of NeoruraleHub, which applies a blue economy model to agriculture.

For short-term storage in a 100% renewables grid, thermal energy storage located at concentrating solar power plants could compete with batteries, according to a new study using an idealized grid model. Seasonal storage needs could best be met with power-to-gas-to-power technology.
