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.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The company is building these shipping container systems, which work like giant batteries that store energy as heat and pressurized air , rather than a chemical reaction (Cheesecake’s name is derived from a nerdy acronym for their technology.) Some companies have landed on thermal storage.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

It is a daunting question that a startup called Polar Night Energy, in the small and chilly nation of Finland (Figure 1), is attempting to answer. A Battery for Heat Made from Sand Noted chemical engineer Donald Sadoway is quoted as saying: “If you want to make a dirt-cheap battery, you have to make it out of dirt.”

UNSW, H2Store to develop hydrogen storage for renewables; residential and commercial P2G

Green Car Congress

Professor Kondo-Francois Aguey-Zinsou and his team at UNSW’s School of Chemical Engineering have developed a system that provides cheap storage and transportation of hydrogen which they expect will provide a new alternative for energy storage within two years. with a particle size below 10 nm).

Power-to-gas trial to inject hydrogen into Australia’s gas grid; A$5M award to AquaHydrex

Green Car Congress

The Australian Renewable Energy Agency (ARENA) announced a trial for a new type of electrolyzer which could see excess renewable energy stored in the gas grid and used to decarbonize Australia’s gas supply. In the future, there will be increasing amounts of surplus renewable energy when it is sunny or windy.

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.

It’s about one-twentieth the size of the minibus-scale geostationary satellites already in orbit, allowing for cheap and quick deployment. The world’s largest pumped-energy-storage station—a technique that stores energy by pumping it uphill to a reservoir—is set to complete phase two of its construction in 2023.
