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.,

NSF awards UCSD team $39M to improve integration of distributed energy resources into grid; EV batteries also

Green Car Congress

Solar panel output depends on the weather, for example, as do wind turbines. At the other end of the grid, electric vehicles need charging for only a certain amount of time every day, and when not in use could be used as temporary batteries to store energy from renewables.

Wind Explorer EV crosses Australia for less than $15 of electricity; kite-assisted

Green Car Congress

Evonik Corporation is featuring the Wind Explorer—a lightweight, electric vehicle that crossed Australia on less than $15 of electricity—at its administrative center in Parsippany, N.J. The Wind Explorer took advantage of crosswinds by using large, steerable kites to cover hundreds of miles. Click to enlarge.

Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

For the implementation of a sustainable energy economy, the greatest challenge is the weather-depending, fluctuating electricity production of wind and solar power plants. To store the green electricity in a highly scalable way, it must be converted into chemical energy. Energy Environ. doi: 10.1039/D0EE03659E.

New electrocatalyst converts CO2 into ethanol, acetone, and n-butanol with high efficiency

Green Car Congress

Excess energy produced by photovoltaics and wind energy could be stored through the electrocatalytic production of fuels from CO 2. Conversion into liquid fuels would be advantageous because they have high energy density and are safe to store and transport. These could then be burned as needed. and Xiong, Y.
