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.

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. Click to enlarge.

Leading UK scientists set out resource challenge of meeting EV targets by 2050

Green Car Congress

Over the next few decades, global supply of raw materials must drastically change to accommodate not just the UK’s transformation to a low carbon economy, but the whole world’s. Energy cost of metal production: This choice of vehicle comes with an energy cost too. million cars that requires 22.5

Baker Institute team explores hydrogen production via methane pyrolysis with co-generation and sale of carbon products

Green Car Congress

Hydrogen as a zero-carbon energy carrier has the potential to transform fundamentally the global energy landscape—but the production must benefit the environment, according to experts at Rice University’s Baker Institute for Public Policy. The largest markets for non-combusted carbon are carbon black (~10s MT), graphite (~0.1

DOE awarding $35M to 11 projects for hydrokinetic turbine development; ARPA-E SHARKS

Green Car Congress

These methodologies will significantly decrease the levelized cost of energy (LCOE) of the final HKT design. The National Renewable Energy Laboratory will expand its open-source Wind Energy with Integrated Servo- control (WEIS) toolbox to include control co-design capabilities of tidal and riverine hydrokinetic turbines.

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.).

UK study finds Bio-SNG could offer 90% reduction in lifecycle CO2; lower cost of carbon abatement than electrical solutions for transport applications

Green Car Congress

Cost of carbon abated for transport applications. Implementation of Bio-SNG will only take place with the appropriate tax, incentive and legislative environment. Cost of carbon abated. Strategically the UK needs to consider the most cost effective approach for decarbonizing, the report notes. Click to enlarge. Feedstocks.
