Global warming gases

In order for hydrogen fuel cell vehicles to reduce global warming gases, the electrolysis process will need to become more efficient, and the electric power will need to be produced from a higher percentage of low-to zero-carbon sources (renewables or coal with carbon capture and storage). 

Carbon dioxide is one of the maj or global warming gases. The ocean acts as a reservoir for carbon dioxide and therefore will slow the effects of this gas on global warming. How is this air-water transfer rate dependent on the rate of reaction of carbon dioxide with liquid water to form H2CO3 ... 

For other emissions, such as potential global-warming gases, the norm will depend on the time horizon of the application. If the application is foreseen for a long time horizon, say, 50 years, then the global-warming gas emissions should be reduced by a factor of 4-10 compared to the present (27). 

Compared with the United States, the European Union has been significantly more aggressive in its production reduction to date and scheduled reduction of HCFC production, and it is considering restrictions in the use of HFCs in compliance with Kyoto Protocol goals to limit the emissions of global warming gases. 

The results indicates that the nylon alternative has certain advantages from an environmental point of view. Resource consumption in the form of energy and material, global warming gases (CO2 and N2O) and consumed landfill volume all speak in favour of the ZYTEL alternative. Only the contributions to acid rain (NO and CO2) are approximately equal for the two materials. 

Our goal is to further reduce global-warming gases by an additional 12% by 2016.

But for power station applications, the thermal efficiency is not the only measure of the performance of a plant. While a new type of plant may involve some reduction in running costs due to improved thermal efficiency, it may also involve additional capital costs. The cost of electricity produced is the crucial criterion within the overall economics, and this depends not only on the thermal efficiency and capital costs, but also on the price of fuel, operational and maintenance costs, and the taxes imposed. Yet another factor, which has recently become important, is the production by gas turbine plants of greenhouse gases (mainly carbon dioxide) which contribute to global warming. Many countries are now considering the imposition of a special tax on the amount of CO2 produced by a power plant, and this may adversely affect the economics. So consideration of a new plant in future will involve not only the factors listed above but also the amount of CO2 produced per unit of electricity together with the extra taxes that may have to be paid. 

One of the main benefits from future use of biofuels would be the reduction of greenhouse gases compared to the use of fossil fuels. Carbon dioxide, a greenhouse gas that contributes to global warming, is released into the air from combustion. Twenty-four percent of worldwide energy-related carbon emissions in 1997 were from the United States. Carbon...
