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. Renewable energy sources are central to the energy transition toward a more sustainable future.

Electrovaya launches Li-ion residential energy storage system; 3 kWh – 20 kWh

Green Car Congress

The battery stores power from the grid or from solar panels and stores it for later household use. For consumers subject to time-of-use charges, the EnergyBlock can be used to store off-peak power to be used later during peak times, lowering the amount of peak-rate costs for the user.

Swansea team develops faster, greener way of producing carbon spheres

Green Car Congress

A fast, green and one-step method for producing porous carbon spheres—a component for carbon capture technology and for new ways of storing renewable energy—has been developed by Swansea University researchers. It uses a cheap and safe feedstock which is readily available in the market. It is a rapid and safe procedure.

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

Green Car Congress

Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. The technology could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and sun far more economical and reliable. Background.

UT and ORNL researchers develop new class of pseudocapacitor; anion-based intercalation pseudocapacitance

Green Car Congress

Unlike other devices, the team’s is the first to utilize oxygen anions (negatively-charged ions) instead of cations (positive ions) to store its energy. The device uses a perovskite material (LaMnO 3 ), a structure containing vacant sites where oxygen anions can be stored, making these advancements a possibility.

KU Leuven team creates solar panel that produces hydrogen from moisture in air

Green Car Congress

The hydrogen gas produced in the summer will be stored and converted into electricity and heat in the winter. The hydrogen gas produced in the summer can be stored in an underground pressure vessel until winter. We’re using cheap raw materials and don't need precious metals or other expensive components. —Johan Martens.
