Greenhouse reduction

Therefore, there is no energy efficiency gain or greenhouse reduction effect using CO2 reforming of methane for the production of hydrogen. 

Dealing with CO2 emissions. If CO2 emissions are of concern because of the greenhouse effect, then there are only two ways in which reductions can be made ... 

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...

Nitrous oxide has received increasing attention the last decade, due to the growing awareness of its impact on the environment, as it has been identified as an ozone depletion agent and as a Greenhouse gas [1]. Identified major sources include adipic acid production, nitric acid and fertilizer plants, fossil fuel and biomass combustion and de-NOx treatment techniques, like three-way catalysis and selective catalytic reduction [2,3]. 

The annual impact of shifting all the pig herd in Denmark to a phytase supplemented diet instead of MCP supplemented would be a reduction in greenhouse gases by 27 kT CO2 equivalent, reduction in acidification by 450 T SO2 equivalent, reduction in nutrient enrichment by 1200 T phosphate equivalent, and avoiding mining of 20 kT phosphate bearing rock.

Developing countries like India are listed under Kyoto as Annex II countries, and they are not obliged to make any cuts in greenhouse emissions reduction yet. But as they raise living standards their emissions will obviously increase India s have risen by more than 52% since 1990. Under Kyoto, they will have to accept reduction targets in a few years from now. The protocol s architects say it is fair to allow them a grace period, because the problem has been caused by the industrialised countries. But India, with more than 1 bn people, will soon be a major polluter. 

Taking this into account I look forward to a productive NATO Summer School with new motivation to shift to energy conservation techniques of the new millennium in meeting Kyoto Targets for the reduction of greenhouse gas emissions in order to combat climate change.
