Space-based Solar Power: A Great Idea Whose Time May Never Come

Cars That Think

The scene: A space-based solar power station called the Converter being commissioned some time in the Future. It’s pretty clear Asimov had no idea how a system like the Converter would actually work, except in the most basic terms. Harnessing the power of the sun in space is certainly an enticing idea. For example, U.K.-based

5 Big Ideas for High-Temperature Superconductors

Cars That Think

But the materials could show up sooner in a wide array of practical applications, including wind power, energy storage, and nuclear magnetic-resonance machines. HTS materials offer high power density and high efficiency in a compact and lightweight package.

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

Green Car Congress

According to a new study published by the ifo Institue Center for Economic Studies (CESifo) in Germany, EVs will barely help cut CO 2 emissions in the country over the coming years, as the introduction of electric vehicles does not necessarily lead to a reduction in CO 2 emissions from road traffic given the current power generation mix.

ARPA-E issues $5M funding opportunity to support upcoming grid optimization competition

Green Car Congress

The Advanced Research Projects Agency - Energy (ARPA-E) issued a funding opportunity announcement ( DE-FOA-0001952 ) of up to $5 million for research and development of algorithms to modernize the electric grid. If successful, awardees will participate in Challenge 1 of ARPA-E’s Grid Optimization (GO) Competition , set to launch in fall 2018.

New Fraunhofer membrane technology enables co-transport of hydrogen and natural gas

Green Car Congress

This technology makes it possible for the two substances to be routed through the national natural gas grid together and then isolated from one another at their final destination. If hydrogen is collected from renewable sources such as wind and solar power, there are no climate-damaging emissions.

Audi e-gas plant qualified to participate in balancing market to stabilize grid

Green Car Congress

The Audi e-gas plant in the city of Werlte in Lower Saxony ( earlier post ) produces CO 2 neutral-fuel (synthetic methane from water, renewable electricity and CO 2 ); it now also contributes toward stabilizing the public power grid. This has resulted in the plant being accepted under the direction of grid operator Tennet TSO GmbH.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

The technology could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and sun far more economical and reliable. Solid-electrode batteries maintain discharge at peak power for far too short a time to fully regulate wind or solar power output.
