The system will provide district heating to the city of Kankaanpää in western Finland. It has 100 kW of heating power and 8 MWh of energy capacity.

The new world record was independently certified by the National Renewable Energy Laboratory (NREL) in the United States.

Salient Energy developed the water-based zinc-ion battery to have the same power, performance, and footprint as lithium-ion systems without the safety risk.

Thin-film cadmium telluride panels may have a $0.02 to $0.04 per watt carbon cost advantage over traditional polysilicon, said the National Renewable Energy Laboratory in an analysis of embodied carbon, embodied energy, and energy payback.

Developed by Chinese manufacturer Enerack, the carport can host all types and sizes of solar panels and relies on waterproof technology for rain protection.

The heat storage tank is 45 m high and has a capacity of 56 million liters. It will store district heating water at a temperature of 98 C and, according to Vattenfall, will use heat produced with renewable electricity coming from the grid.

Japanese scientists built a near-invisible solar cell based on indium tin oxide (ITO) and tungsten disulfide (WS2) as a transparent electrode and a photoactive layer, respectively. The cell has the potential to achieve a transparency of 79%.

Indian developer Acme will set up a green hydrogen and ammonia project in Tamil Nadu with 1.5 GW of electrolysis capacity and 1.1 million tons of ammonia synthesis, powered by a 5 GW solar plant.

US researchers find that placing agrivoltaic installations along highways to power EV charging stations can reduce both carbon emissions and range anxiety.

According to a third-party study, the projected output over the 40-year warranty period of Maxeon solar panels exceeds the energy demand of manufacturing them by over 100-fold. Plus, more details from the Maxeon 2021 sustainability report.
