Performance optimisation of the combined single flash binary geothermal power plant

In this paper, the optimal operating conditions of a hypothetical combined single flash-binary geothermal power plant are investigated and performance analyses are performed based on Aydin-Germencik field in Turkey. The relationship between flashing pressure, turbine inlet pressure of the binary cycle and total heat transfer area of the heat exchanger are determined for maximum power output of ...

Run cars on green electricity, not natural gas

With the dramatic increase in oil prices earlier this year translating into higher prices at the gas pump in the United States, concerns over US dependence on foreign oil are once again part of the national discussion on energy security. Combined with the growing understanding that carbon emissions from the combustion of fossil fuels are driving global climate change, the debate is now focused on ...

Landfills Expand Energy Output

HIGH fossil fuel prices and growing concern about global climate change are creating favorable conditions for landfill gas energy (LFGE) projects. Notably, endorsement of LFGE by Federal agencies and many states as a form of “green” power has enabled LFGE developers to earn premiums for electricity marketed through green power programs, and to benefit from expanded federal tax credits for ...
