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.

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. The analysis found that the energy requirements, the capital, and the operating costs of seawater desalination are marginal compared to those of water splitting.

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. Only when wind replaced coal itself did social costs decrease.

McMaster switched reluctance motor spinout Enedym closes $15M funding round

Green Car Congress

The Enedym team has developed a disruptive way to design electric motors at a fraction of the time and cost of existing methods. In a switched reluctance motor, torque is produced by the magnetic attraction of a steel rotor to stator electromagnets; there are no permanent magnets, and the rotor carries no windings.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. The data revealed that all five battery technologies have high embodied-energy costs compared with pumped hydroelectric storage. Energy Environ.
