Study finds GWP of electrolyzed hydrogen to meet ORD’s fuel needs would be 2.5x that of fossil fuels with 2020 grid mix

Green Car Congress

However, the development of a fully renewable electrical grid in the US by 2035 is technically and socially viable, and if realized electrolyzed hydrogen can serve as a compelling zero-emissions solution for aviation. He looked at three different resources that forecast the future composition of the US electrical power grid.

Opinion: Reinventing fuel-based power for a more secure and resilient grid

Green Car Congress

It is, however, a challenge that is being made all the greater as we continue to decentralize power generation with more distributed, variable and inflexible sources, such as wind and solar. Our grid is changing, and so must the way we operate it. What are the mechanisms we need to balance a renewable grid?

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.

NREL researchers evaluating blockchain for transactive energy applications

Green Car Congress

The Congressional Research Service last year noted increasing interest among producers of distributed energy resources (DERs)—such as rooftop solar—to sell electricity to neighbors. The results highlighted the path for future research. Potential opportunities abound for the use of blockchain in the energy sector.
