Natural gas and efficient technologies: A response to global warming

PDF Version Also Available for Download.

Description

It has become recognized by the international scientific community that global warming due to fossil fuel energy buildup of greenhouse CO{sub 2} in the atmosphere is a real environmental problem. Worldwide agreement has also been reached to reduce CO{sub 2} emissions. A leading approach to reducing CO{sub 2} emissions is to utilize hydrogen-rich fuels and improve the efficiency of conversion in the power generation, transportation and heating sectors of the economy. In this report, natural gas, having the highest hydrogen content of all the fossil fuels, can have an important impact in reducing CO{sub 2} emissions. This paper explores natural ... continued below

Description

It has become recognized by the international scientific community that global warming due to fossil fuel energy buildup of greenhouse CO{sub 2} in the atmosphere is a real environmental problem. Worldwide agreement has also been reached to reduce CO{sub 2} emissions. A leading approach to reducing CO{sub 2} emissions is to utilize hydrogen-rich fuels and improve the efficiency of conversion in the power generation, transportation and heating sectors of the economy. In this report, natural gas, having the highest hydrogen content of all the fossil fuels, can have an important impact in reducing CO{sub 2} emissions. This paper explores natural gas and improved conversion systems for supplying energy to all three sectors of the economy. The improved technologies include combined cycle for power generation, the Carnol system for methanol production for the transportation sector and fuel cells for both power generation and transportation use. The reduction in CO{sub 2} from current emissions range from 13% when natural gas is substituted for gasoline in the transportation sector to 45% when substituting methanol produced by the Carnol systems (hydrogen from thermal decomposition of methane reacting with CO{sub 2} from coal-fired power plants) used in the transportation sector. CO{sub 2} reductions exceeding 60% can be achieved by using natural gas in combined cycle for power generation and Carnol methanol in the transportation sector and would, thus, stabilize CO{sub 2} concentration in the atmosphere predicted to avoid undue climate change effects. It is estimated that the total fossil fuel energy bill in the US can be reduced by over 40% from the current fuel bill. This also allows a doubling in the unit cost for natural gas if the current energy bill is maintained. Estimates of the total net incremental replacement capital cost for completing the new improved equipment is not more than that which will have to be spent to replace the existing equipment conducting business as usual.
