Reddit mentions of Solar Hydrogen: Fuel of the Future

Renewable hydrogen can be produced using solar and or wind energy. Here's a great book that lays it out http://www.amazon.com/gp/product/1849731950/

Here's what Germany is doing:
>To date, according to press material provided by Mercedes-Benz, Linde produces half of the hydrogen for existing fuelling stations from sustainable energy sources. The gas is obtained from crude glycerol, which is a by-product of biodiesel production. Biodiesel, as the name indicates, is a carbon-neutral fuel produced from plant life and other biological sources.

>Linde also splits water molecules by passing a current through the water, with the electricity procured from wind power generation. http://www.motoring.com.au/news/2014/mercedes-benz/germany-builds-more-hydrogen-filling-stations-46711

China does not think "all that h2 stuff is garbage". Quite the contrary, they are prioritizing hydrogen/fuel cells as detailed in the "Made in China 2025" paper. FC excerpt here: http://www.ihfca.org.cn/file/FCV%20Tech%20Roadmap.pdf

Hydrogen is how to store excess solar energy

>LA Times: California invested heavily in solar power. Now there's so much that other states are sometimes paid to take it http://www.latimes.com/projects/la-fi-electricity-solar/
