Solar and Battery Companies Rattle Utility Powerhouses

Cars That Think

It's being marketed as the " Tesla Energy Plan ," and is available to any individual household in this region of 24 million people that has a solar panel system, a grid connection—and a Tesla powerwall, the Palo Alto firm's gigafactory-made 13.5 kWh battery wall unit. For bigger national grids it gets more complicated.

ORNL demos 20 kW bi-directional wireless charging on UPS PHEV truck; 11" air gap, >92% efficiency

Green Car Congress

With its bi-directional design, the system also supports use of the vehicle’s batteries for energy storage. Doing so would give energy flexibility to a fleet owner’s business, and help better manage on-site generation such as solar power. —Mike Whitlatch, vice president of Global Energy and Procurement for UPS.

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

Green Car Congress

As the fraction of electricity generation from intermittent renewable sources—such as solar or wind—grows, the ability to store large amounts of electrical energy is of increasing importance. With a whole field of turbines or a large solar farm, one could imagine a few very large storage tanks.

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

Green Car Congress

Global public support now totals about $1 billion per year, leveraging many times that amount in private funds. 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. Transition issues.

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. Until recently most power stations relied on coal and gas to power generators. 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. Gas is the only answer. Climate Change.

Study Finds Bioelectricity Better Option Than Liquid Biofuels for Transportation Output and GHG Emissions

Green Car Congress

The authors point out their study looked at only two criteria, kilometers travelled and greenhouse gas offsets, but did not examine the performance of electricity and ethanol for other policy-relevant criteria such as water consumption, air pollution or economic costs. “We
