Estimates of the price of hydrogen as a medium for wind and solar sources

The rejection of hydrogen as a solution to global warming by becoming the medium of wind and solar was made when gasoline was priced at $1/gallon. ind, H2 would now cost (by electrolysis of water and steam) less than $3 for an amount equivalent in energy to that in a gallon of gasoline (“equivalent”). From solar photovoltaics (pv), H2 would be sinking in price between $8 toward $5 equivalent as the efficiency of solar pv increases toward 20%.11Calculated price estimates stated here include 25% profit and the cost of piping H2 1000 miles. Unless otherwise stated, prices are in 2006$. thermalʹs present prices offer about one-half the solar pv prices. tion of the maximum of the delivery rate of world oil is [Laherreʹs Oil Production Forecast, 1950–2150.

The common media will be hydrogen and electricity. These sources yield energy at around one-half the cost of nuclear fission. g corn to make alcohol involves a net loss of energy and need for a heating mechanism.22Growth of the plant fueled by solar light and CO2, forming alcohol involves a heating stage and numerous operatives use fossil fuels, thus introducing CO2. This ruins the “no CO2” process. However, it is pointed out in this paper that one could use an excess of the first stage biofuel to provide heat and this would run on CO2 and light, i.e., no net CO2 in burning. y increase the Greenhouse.
