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.

To Store or Not to Store: That is the Question

Green Car Congress

Typical daily grid demand. “ Why do you need energy storage on the grid, when the grid is full of power plants that generate all the energy that is needed? ” It would seem like a good question to ask and applies the same logic has been used for the past fifty years in determining grid strategy.

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.).

Role of Batteries in Clean Energy Transitions – ET Auto

Baua Electric

The Challenge of Intermittency and the Role of Batteries The transition to renewable energy sources such as solar and wind power is gaining momentum globally. For instance, during periods of reduced solar irradiance or wind speed, traditional energy sources such as coal often experience a surge in production to meet demand.
