Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Only about 3% currently is generated from wind, solar, hydroelectric and other renewable sources, with most of the electricity produced in the United States currently coming from coal- and natural gas-fired power plants, followed by nuclear according to data from the US Energy Information Administration (EIA).

The Case for Nuclear Cargo Ships

Cars That Think

“At the same time, it’s becoming apparent that alternative-fuel solutions we’re looking at have big drawbacks, and that producing these fuels will take a lot of green power that will be needed to replace coal and gas on shore. The group has shortlisted three designs and plan to have picked one by the end of 2024.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

The WTW analysis focused solely on the fuel-motive power cycle, disregarding the vehicle cycle—i.e., the associated energy and emissions for the battery, power electronics, and auxiliary systems found only on battery EVs and for the CNG tank and auxiliary systems only found on natural gas vehicles.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

And the Norwegian company H2Carrier recently received approval in principle for its concept for an industrial-scale floating production unit to make green ammonia at sea. Airplanes, for example, won’t be able to fly long distances on battery power. The process emits about 10 tonnes of CO2 per tonne of hydrogen.

Volt for Real?

Plug In Partners

Even he recognizes that the Volt will make historians forget about the (in my opinion) entirely forgettable Dodge Viper he concocted at Chrysler, as well as the 1000 horsepower Cadillac Sixteen concept car of a few years ago. The Volt will even make people forget that it was Lutz who gave us the Pontiac Solstice and Saturn Sky.

Naysayer Alert – the hydrogen red herring

My Electric Car

The energy stored within hydrogen has been imparted from electrical energy through the electrolytic hydrogen production process or more likely in the refinement of fossil fuels such as coal seam (methane) gas – both are energy intensive processes in themselves. . So why haven’t FCEV becoming as prolific as other electric cars?
