Photovoltaic vs nuclear fusionWe write the year 2040. The resarch ober nuclear fusion has made the necessary progress for a commercial operation, but what is with the economy?Worldwide are 50 TW photovoltaic installed producing 75,000 TWh electric power per year. For the day/night balancing are 250 TWh lithium batteries world wide used. According to the knowledge from 2008, 10 million tons would be the greatest part of world wide reserves, but for luck at this high demand, some additional mines had been found.
In the summer time is such overflow from solar electric power, that there is supply of hydrogen created by electrolysis for the winter. The hydrogen produces in CCPP electric power in the winter. This power plants have to purchase 2.5 kWh electric power in the summer to produce 1 kWh electric power in the winter.
Today, it's estimated, that a nuclear fusion power plant is 3 times more expensive than a conventional fision power plant. New is the recognition about the low run time. In the summer time is no chance against solar electric power. But when electric power is only produced in winter, the high investition is distributed on to few run time hours. |
