Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.

Wind Turbine Blades Destined for the Afterlife

Cars That Think

This group of wind-turbine fan blades, fresh from Siemens Gamesa’s new RecycleBlade manufacturing process at England’s largest such factory, await shipment to the various points around the globe where they will serve 20- to 30-year stints generating electricity at wind farms before they’re recalled and reincarnated. What’s Next?

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 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.

Air France KLM signs 210M gallon SAF offtake agreement with DG Fuels

Green Car Congress

The feed-stock reduction is achieved primarily by supplementing the process with oxygen and hydrogen produced by water electrolysis units that are powered by clean wind and solar generated electricity. DGF replaces the coal gasification used by others with biomass gasification and natural gas reforming.

BMW Group plans to source steel produced with green power and hydrogen from H2GS in Sweden

Green Car Congress

From 2025 on, the company plans to source steel produced with up to 95% less CO 2 emissions and without requiring fossil resources such as coal. The company will use only green electricity from local wind and hydroelectric power to produce the battery cells.

Trestle Energy and Larksen partner to reduce CO2 from ethanol and coal power

Green Car Congress

Trestle and Larksen’s integrated approach furthers ethanol producers’ ability to scale up production of low carbon biofuels and allows existing power plants to generate electricity with the cost and reliability of coal and with carbon emissions similar to wind.
