Concerns about global climate change have prompted interest in reducing or eliminating the carbon dioxide (CO2) emissions of fossil fuel-fired power plants. Here’s a guide to the technology and economics of three CO2 capture methods: postcombustion separation Of CO2 from flue gas (applicable to existing plants), and oxygen-fired combustion and precombustion capture (suitable for new coal-fired capacity, including IGCC plants).

Impact of electric power generation on green house gas emissions in Europe: Russia, Greece, Italy and views of the EU Power Plant Supply Industry - a critical analysis

Hammons, TJ


This paper analyses the impact of electric power generation on greenhouse gas emissions in Europe (including the Asian part of Russia) with reference to Russia, Greece, Italy, and views of the EU power plant supply industry in respect of the Kyoto protocol. The outlook of power industry development in Russia in the 21st century is first considered and its impact on Russia’s greenhouse gas emissions is examined. Forecasts for developing Russia’s economy and electric power industry in the first half of the 21st century are presented. Possible structural change in the electric power industry in Russia together with dynamic changes Of CO2 emissions from fuel combustion in power plants are examined. It is shown that CO2 emissions from fuel combustion at power plants in Russia may increase 2.7-fold in 50 years. Calculations depict that specific CO2 emissions in Asian Russia exceed greatly that of the European part. It then reviews measures to limit greenhouse gas emissions in Greece. Impact of the currently adopted measures and initiatives to reduce emissions in the Greek energy system for the period up to 2030 is discussed with emphasis on the current decade. Under the scenario for environmental policy, the additional commitments and measures to limit CO2 emissions towards the Kyoto targets are discussed. The paper summarizes a possible Italian strategy for implementing Kyoto protocol mechanisms to meet commitments of the EU Emission Trading Draft Directive, the Italian strategy in the Ministerial documents, and final considerations. It then examines clean power generation technology for the 21st Century and gives a perspective from the EU power plant supply industry. A perspective is presented with respect to impact of global climate change on product development strategy. Fossil fuel based power generation technologies will continue to play an important part of the energy mix in the foreseeable future and different parts of the world will require different technologies to meet their local specific requirements. It will be necessary to continue to develop clean technologies and to promote their use world-wide. (c) 2006 Elsevier Ltd. All rights reserved.
