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. Dabek, P.B., Brandão, R., Patro, E.R., Leal Filho, W., van Ruijven, B.,

Cemvita demonstrates “gold hydrogen” production in situ, sets up subsidiary

Green Car Congress

Cemvita defines Gold Hydrogen as the biological production of hydrogen in the subsurface through the consumption of trapped or abandoned resources. Traditional methods of producing hydrogen without greenhouse gas emissions (green hydrogen) include electrolysis powered by renewable sources such as wind, solar, or hydro. billion in 2020.

CMU researchers find controlled charging of PHEVs can cut cost of integration into electricity system by 54-73%; higher benefits with wind power

Green Car Congress

The magnitude of these savings is ~5% to 15% higher in a system with 20% wind penetration compared to a system with no wind power, and the savings are 50–60% higher in a system that requires capacity expansion. Controlled charging can also take advantage of the high levels of wind generation that commonly occur at night in the US.

IIASA study proposes solid air hydrogen liquefaction as efficient addition to hydrogen liquefaction supply chain

Green Car Congress

The possibility of selling hydrogen could result in a further expansion of solar and wind power in developing countries, contributing to their economies. The hydrogen is liquefied where electricity is cheap. —Julian Hunt Resources Hunt, J., Also, SAHL can lower energy consumption for hydrogen liquefaction by 25 to 50%.

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

Green Car Congress

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. Solid-electrode batteries maintain discharge at peak power for far too short a time to fully regulate wind or solar power output. —Michael J.
