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.

How Smart EV Charging Will Help Promote Renewable Power Generation

Wallbox

The proportion of grid electricity generated by renewables such as wind and solar energy fluctuates depending on how hard the wind is blowing or how strong the sun is shining. With grids increasingly powered by renewables, electrical demand has to follow supply. The EV as a mobile electricity storage device.

Mad Power thoughts

EV Info

Wind farms stand idle for days on end, a fire interrupts a vital cable from France, a combination of post-Covid economic recovery and Russia tightening supply means the gas price has shot through the roof – and so the market price of both home heating and electricity is rocketing. This was plain wrong.

UC Davis researchers suggest we may be at the beginning of a real hydrogen transition in transportation

Green Car Congress

Low-cost shale gas has improved the prospects for natural gas-derived hydrogen, especially in the United States, where it is a major force in the resurgence of federal interest in hydrogen energy. Global public support now totals about $1 billion per year, leveraging many times that amount in private funds.
