MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. The key to this Ocean Renewable Energy Storage (ORES) system is the placement of 30-meter-diameter hollow concrete spheres on the seafloor under the wind turbines. Earlier post.).

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

When we turn up the heat in our homes and workplaces, we must balance our personal need for warmth with the global impact of burning fossil fuels like oil, gas, coal, and biomass. The hot air then flows back out of the vessel into a heat exchanger, where it heats water that is then circulated through building heating systems.

National Research Council Report on Americas Energy Future Highlights Vehicle Efficiency Technologies, Conversion of Biomass and Coal-to-Liquids Fuels, and Electrifying the Light Duty Fleet with PHEVs, BEVs and FCVs

Green Car Congress

Developing technologies for the conversion of biomass and coal-to-liquid fuels. By 2035, cellulosic ethanol and/or coal-and-biomass-to-liquid (CBTL) fuels with carbon capture and storage could replace about 15% of current fuel consumption in the transportation sector (1.7–2.5 emissions, according to the report.

How EVs Charge Your Sustainability Strategy

Blink Charging

This is why it’s a good idea to switch your fleet from internal combustion engine vehicles to EVs. The source of the electricity – whether renewable sources like wind, solar, or water, or nonrenewable sources like coal – is also important. However, emissions are about more than just the tailpipe.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

Some offset projects may provide further benefits, such as: (a) the promotion of sustainable development; (b) improvements in air or water quality; (c) the creation of new domestic and international economic opportunities; and (d) the incentivization of innovation as parties seek new methods of generating offsets. 2) Supplementarity.

How to Prevent Blackouts by Packetizing the Power Grid

Cars That Think

Spiking demand for electric heat collided with supply problems created by frozen natural-gas equipment and below-average wind-power production. Second, conventional coal and nuclear plants are being retired for economic and policy reasons, removing stable sources from the grid. unprecedented and deadly winter freeze.
