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. An open-access paper on the work is published in the journal Energies.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

Cheesecake is part of a cohort of companies trying to meet a growing need for alternative forms of energy storage. As countries transition away from fossil fuels to green sources of energy like wind and solar, there will be natural lulls in energy production due to weather conditions.

ICL researchers develop new membrane-based system for cheap, efficiently made biofuels

Green Car Congress

Our new technology could help to drive down the cost of biofuels so that they eventually replace fossil fuels in transport and aviation—a much happier situation for the environment and one we are all working towards. —Kim et al. —Professor Andrew Livingston of Imperial’s Department of Chemical Engineering.

Utility solar dethrones coal as the cheapest power source in Asia

Baua Electric

Photo: China News Service Renewable energy costs in Asia last year were 13% cheaper than coal and are expected to be 32% cheaper by 2030, according to a new study. This is significant because it marks a shift toward making renewables increasingly competitive with coal, a mainstay in APAC’s energy mix.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones. —Huskinson et al.
