Energy Storage: ‘Windgas’ could drive car industry

Bdlive.co.za | Horst Hamm | December 01 2015

FOR all the talk about the imminent end of the oil era, 99% of the cars, trucks and planes currently operating are still petrol-powered.

German Chancellor Angela Merkel has insisted that change is on the way: in 2011, she predicted that 1-million electric cars would be in use in Germany by 2020. Yet, as of January 1 this year, there were only about 19,000 electric cars registered in Germany...snip

..Superfluous ecoelectricity from wind turbines and solar panels can be used to produce hydrogen and relatively simple organic compounds, such as methanol and methane. These compounds can be used to power cars, either in a combustion engine, or with the use of a fuel cell that can transform the materials back into electricity.

This is precisely the alternative Audi has been exploring in Werlte, Lower Saxony, where it commissioned Etogas to build the first power-to-gas plant.

Power-to-gas is the process by which wind and solar power are transformed into hydrogen and methane, a technique developed at the Centre for Solar Energy and Hydrogen Research in Stuttgart...snip

E.ON Power-to-Gas facility in Falkenhagen with Hydrogenics technology

Dec 11, 2013

On August 28, 2013, E.ON inaugurated commercial operations at its Power-to-Gas (P2G) facility in Falkenhagen, Germany. The plant uses wind power and Hydrogenics' electrolysis equipment to transform water into hydrogen, which is then injected into the existing regional natural gas transmission system. The hydrogen, as part of the natural gas mix, can be used in a variety of applications including space heating, industrial processes, mobility, and power generation. The facility, which has a capacity of two megawatts, produces 360 cubic meters of hydrogen per hour.

1. *sigh*


Hydrogen is very poor bang for the buck. Yes, it can be used as a storage medium, but it is a pretty poor one. It realistically takes about 51kWHs of electricity to create, store and dispense a single kg of hydrogen (and this number is disputed). That kg of hydrogen is re-converted to electricity and can power a Hyundai Tucson for about 47 miles. However, if I use that 51kWh to charge my Nissan Leaf, I can drive about a 180 miles.

Absent some MAJOR tech breakthrough in making hydrogen, it is not an economical fuel.
