GE using Large Eddy Simulation on Sandia’s Red Mesa to lay groundwork for quieter wind turbine blades with better power yield

Green Car Congress

Transition of flow to turbulence on a wind-turbine airfoil; isosurfaces of vorticity from a Large Eddy Simulation (LES). A 1 decibel quieter rotor design would result in a 2% increase in annual energy yield per turbine. Aeroacoustic noise is more difficult to mitigate, and is the dominant noise source on modern wind turbines.

World Bank Group: mineral production to soar as demand for clean energy increases

Green Car Congress

It estimates that more than 3 billion tons of minerals and metals will be needed to deploy wind, solar and geothermal power, as well as energy storage, to achieve greenhouse gas emission reductions sufficient to achieve a below 2°C future.

IISA study proposes using airships for efficient cargo or hydrogen transportation

Green Car Congress

Their use in cargo and passenger transport was however quickly discontinued for a number of reasons, including the risk of a hydrogen explosion (for which the Hindenburg disaster of 1937 served as a stark case in point); their lower speed compared to that of airplanes; and the lack of reliable weather forecasts.

Toshiba to participate in 4-year power-to-gas hydrogen fuel project in Scotland

Green Car Congress

Toshiba Corporation will participate in the Levenmouth Community Energy Project in Fife, Scotland, a major 4-year project to investigate the potential of hydrogen as a future fuel. Electricity generated by wind and solar power will be used to power a hydrogen-producing water electrolysis system.

Nissan unveils new EV, plans for battery gigafactory at Sunderland in UK; potentially up to 35 GWh

Green Car Congress

Designed for global markets, UK production will be exported to the European markets traditionally served by Nissan’s Sunderland plant. The new crossover will be built on the Alliance CMF-EV platform, with a forecasted production capacity of up to 100,000 units to be installed. Plant competitiveness and environmental improvements.

Bosch to begin developing electrolyzer components; €500M investment by end of decade

Green Car Congress

Ideally, the electricity for this purpose is generated from renewable sources such as wind or photovoltaic power, in which case the result is known as “green hydrogen”. Bosch firmly believes in hydrogen as a future fuel, and is also working on both stationary and mobile fuel cells. jovice (Czech Republic).
