MIT researchers conclude fundamental changes in the US energy-innovation system are needed to meet challenges of climate change and energy supply

Green Car Congress

The conclusions of that study are detailed in a new book— Unlocking Energy Innovation (MIT Press, 2012)—by Richard Lester, the Japan Steel Industry Professor of Nuclear Science and Engineering at MIT, and David Hart, a professor of public policy at George Mason University. Innovation doesn’t just emerge out of thin air.

PHEVLERs are the Zero CO2 Clean Green Machines of the Future

Green Car Congress

That is, PHEVLERs can store electricity whenever sun and wind-generated electricity is plentiful, and then can send stored power back into the smart grid at times when more electric power is needed. PHEVLERs are better than BEVs in support of the electric grid. 23 ] , [ 24 ]. Advanced biofuels will be ZERO net CO 2 fuels.

Clearing the roadblocks to electrification of heavy-duty trucks

Charged EVs

Electric Island did what we hoped it would do, which was to kick off a movement towards knowing what was possible and what needed to be done. If you don’t build something like that, people can’t refer to it. It’s like gravity has changed for the utility industry. What happens when we plug in 1.2-megawatt megawatt chargers?

AQDSH 2 refers to the reduced form of AQDS. These features lower the capital cost of storage chemicals per kilowatt hour, which sets a floor on the ultimate system cost per kilowatt hour at any scale. Cell schematic. Discharge mode is shown; the arrows are reversed for electrolytic/charge mode. Huskinson et al. Click to enlarge.
