Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Some of the wind farms instead sit in clusters more than 100 kilometers out at sea.

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. California draws more than 20% of its electricity from solar and approximately 7% from wind, with more VRE coming online rapidly. —Drake Hernandez.

BNEF: EV company fundings bright spot as clean energy investment slips in Q3 quarter; 3 China EV companies raise $1.9B

Green Car Congress

The slip in the July-September quarter leaves clean energy investment for the year so far running a modest 2% below that in the first nine months of 2017—leaving open the possibility that 2018 as a whole will end up matching last year’s total, particularly if a few more multibillion-dollar offshore wind deals are concluded before Christmas.

Bosch on importance of renewable synthetic fuels to reach climate goals; e-fuels

Green Car Congress

First, apply electricity generated from renewable sources to obtain hydrogen from water. As their name suggests, renewable synthetic fuels are made exclusively with energy obtained from renewable sources such as the sun or wind. Present studies suggest that a pure fuel cost of between €1.20 Then add carbon. Finally, combine CO?

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.).
