20 years ago was the deep believe of the average builder of a house, fuel oil is eternal and cheap. He constructed his house in this belive, this is his current disaster. 1.-EUR for a litre fuel oil? Heresy!
2 kWh solar electric powrer instead of 1,67 kWh natural gas
A CCPP can produce with 60% efficiency from 1,67 kWh natural gas 1 kWh electric power. Solar electric power becomes cheaper, natural gas more expensive. First is solar electric power direct used. The next step is the day/night storage of solar electric power in lithium batteries. When there is still to much solar electric power, it's possible to make hydrogen out of it and to store the hydrogen in huge underground storages to balance the less solar power in the winter.
0,87 for large scale electrolysis * 0,95 for storage * 0,6 gives 50%
Dynamic electric power price
Always the same electric power price will not be possible. Solar electric power in the summer at a sunny day could be down to 8 Cent. A CCPP has to purchase 2 kWh to produce in winter 1 kWh. When natural gas is at 10 Cent per kWh, natural gas is in this case more expensive than hydrogen from excessive solar electric power.
At the German EEG energy delivery law will be solar electric power in 2020 only 0,1541 EUR. When natural gas is at 20 Cent per kWh, natural gas is in this case more expensive than hydrogen from excessive solar electric power.
Political responsibility or total failure
When natural gas is more expensive than hydrogen by excessive solar power, will we have the same stupid situation as today, or will we be able to have politicians with responsibility?
