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. In a new study led by the International Institute for Applied Systems Analysis (IIASA), an international team of researchers developed a novel way to store energy by transporting sand into abandoned underground mines.

IRENA sees renewable hydrogen at least cost-possible within decade

Green Car Congress

Hydrogen produced with renewable electricity could compete on costs with fossil fuel alternatives by 2030, according to a new report from the International Renewable Energy Agency (IRENA). For that, today’s manufacturing capacity of less than 1 GW would have to massively grow beyond 100 GW in the next 10 to 15 years.
