Future vision solar electric power plentifulness. Shortage of crude oil and biomass. The logical consequence: Biomass and crude oil refined by hydrogen from solar electricity.
Carbon makes hydrogen more easy to transport
With electric power from renewable energy split H2O and connect the hydrogen with carbon to make fuels from methan up to kerosene.
Coal, crude oil and biomass to deliver carbon
Even in a car is hydrogen very troublesomely, in the airplane practical unuseable.
Too much volume, the tanks to heavy. When there will be electric power from renewable energy in abundance, it is possible to produce hydrogen by electrolysis and to optimize the fuel production with it.
How much wood for 100km
1 kg wood contains, depending on sort, 0,4 to 0,5 kg carbon. This is enough to produce methan with 8,25 kWh bis 10,3 kWh. A Plug-in Hybrid medium sized car needs 15 kWh at the plug or 13,5 kWh from the range extender.
When it's possible to make a methan engine with 40% electrical efficiency, 33,75 kWh chemical energy are enough for 100km. This would be 3,3 to 4,1 kg wood for 100km. Additional the electric power to produce the hydrogen to make more methan with the wood.
Plug-in Hybrid with wood and hydrogen
At a distribution of 80% with electric power, 20% with range extender, there would be the following balance for a Plug-in Hybrid car.
12 kWh for 80km in electric drive modus
0,8 kg wood for 20km in range extender modus
8 to 12 kWh electric power to produce the hydrogen to make methan from wood
