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

Green Car Congress

Renewable energy sources are central to the energy transition toward a more sustainable future. However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial.

Rolls-Royce mtu Kinetic PowerPack approved for renewable diesel

Green Car Congress

For HVO, waste vegetable and animal fats and used vegetable oils can be used as base materials, which are converted into hydrocarbons by means of a catalytic reaction with the addition of hydrogen. Power from the public grid drives the synchronous generator, which acts as an electric motor in this operating mode.
