2021-06-23 Glass Fiber & Concrete Flywheel For Storage

This French company uses glass fiber reinforced flywheels for energy storage instead of steel. Quote: << Gennesseaux went on to say. “We are around 10 grams of CO2 per kWh, while lithium-ion batteries are around 40g CO2/kWh, at the same level as steel flywheels.”>> Initially the flywheel will store 10 kWh. It’s buried underground. Steel
