German Agency for Disruptive Innovation supporting development of high-altitude on-shore wind turbines

Green Car Congress

Among the projects being funded by the German Agency for Disruptive Innovation ( SPRIND ) is an effort by Horst Bendix to develop a high-altitude, on-shore wind turbine. The higher a wind turbine is installed, the more efficiently it will work, because the wind is much steadier and blows with greater force at altitude.

Proposed California Bill SB-233 Mandates Bidirectional Charging for EVs to Advance Grid and Climate Protection

Driivz

is evaluating legislation to mandate bidirectional V2G charging capabilities for all EVs and EV charging equipment sold in the state after January 1, 2027. Some are already available via partnerships between automakers, home EV charging manufacturers, and other participants. Most cars sit in parking lots during the day.

CESifo: EVs not the best option for reduction in on-road CO2 in Germany given power mix

Green Car Congress

Unfortunately, due to our grid situation, electric cars are still too early for this strategic goal in the sense of German climate protection efforts. The idea of providing the necessary storage of wind and solar energy with batteries is utopian, as the Leopoldina, Acatech and the Union of Academies of Sciences have emphasized.

Volkswagen striving to make production of the electric ID. carbon-neutral

Green Car Congress

Currently unavoidable CO 2 emissions are offset by investments in certified climate protection projects elsewhere. For charging, Volkswagen recommends the use of energy from renewable sources such as wind power and hydro-power. A savings potential of about 33% was identified for the first step alone by the end of 2019.

As this proportion grows, however, the basic dilemma associated with these renewable energy sources remains: first, electricity cannot always be supplied when it is required and second, on sunny days and in high-wind conditions, there is often a lack of capacity for storing the energy generated.

In generator mode, meanwhile, the alternating current is rectified for charging the battery. In this scenario the power electronics resemble in terms of their task a valve that lets the electrical current flow only towards the battery to be charged. If the battery is fully charged, no regenerative braking occurs. D1, D2, D3.
