IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. While there are many effective solutions for daily energy storage, the most common being batteries, a cost-effective long-term solution is still lacking. Dabek, P.B.,

Researchers use quantum computing method to optimize molecular photoswitches for solar energy harvesting

Green Car Congress

Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. The procedure was based on a dataset of more than 400,000 molecules, which the researchers screened to find the optimum molecular structure for solar energy storage materials.

BMW iX5 Hydrogen in final winter testing close to the Arctic Circle

Green Car Congress

Under these cold conditions, the hydrogen fuel cell drive system displays the same everyday usability as a conventional internal combustion engine. The hydrogen it uses as an energy source is stored in two 700-bar tanks made from carbon-fibre-reinforced plastic (CFRP). Full system power quickly comes on tap.

RINA awards Freudenberg e-Power Systems type-approval for methanol-powered fuel cell system

Green Car Congress

Freudenberg has received Type Approval by the international classification society RINA for its methanol-powered fuel cell system for ocean-going shipping. Converting commercial ships on the high seas to CO 2 -neutral drive systems is a huge challenge. One important factor is the range requirement of the individual ship types.
