National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow MEETING THE CHALLENGE OF CLIMATE CHANGE THROUGH GREEN MANUFACTURING TECHNOLOGIES OF ENERGY Mrinal K. Ghose Asian Development Bank in Vietnam, 113 Regent Estate, Kolkata -700092 Energy security means ensuring that a country can supply lifeline energy to all its citizens at an affordable cost. The paper focuses on the consumption of different primary energy sources and it identifies that coal will continue to remain as the prime energy source in foreseeable future. However, direct use of coal leads to environmental pollution. This paper emphasizes the need to develop green manufacturing technologies where coal can be refined in coal refineries to obtain different fractionated products having different quality – grade – class (QGC) of fuels. Liquefaction of coal affords liquid fuels from coal for further refining for reducing the import of petroleum. The use of ultra clean coal in gas turbines directly will enhance the efficiency of power generation to 52-55% from the existing efficiency of pulverized coal power generation of 33 - 38%.It discusses the mechanisms that are driving global climate change. It highlights the impact of climate change on energy sector and its engineering solutions like clean development mechanism through efficient technologies in terms mining technologies, extraction of coal bed methane and underground coal gasification are discussed in this paper. Challenge lies in de-linking economic growth and environmental degradation. Power plant performance improvement is required to support public and private power plant operators. To reduce green house gas emission it has become important to justify the use of nuclear energy. The danger of radiation due to the damage cased by earthquakes and tsunamis are discussed. The Renewable Energy Potential like solar energy, energy from agricultural wastes, wind energy, carbon sequestration, integrated gasification combined cycle, fuel cells are also discussed in this paper. The paper concludes that green manufacturing technology as proposed here can meet the energy security of a country in a sustainable manner. 56
National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow CO 2 SEQUESTRATION TECHNOLOGY FOR MANAGING CARBON IN THE ATMOSPHERE Malti Goel Jawaharlal Nehru University, New Delhi email: malti_g@yahoo.com The Carbon Capture and Storage (CCS) is providing new paradigms in research in inter-disciplinary areas for tackling environment pollution. It aims at reducing atmospheric CO 2 concentrations, either through reduction of emissions by the use of clean technologies or capture of excess CO 2 from the atmosphere. The technology for CO 2 sequestration is fast developing and a lot of activity to launch pilot and demonstration projects in CCS is taking place globally. The Carbon Capture and Storage (CCS) is based on capturing CO 2 from its large point sources and safely storing in underground reservoirs so that it does not enter the atmosphere again. The CO 2 storage is not yet acceptable and favored approach unlike most of the other CO 2 neutral energy technologies. Increased understanding of earth processes is required through simulations and observations to address some of the issues and concerns arising out of CO 2 storage. In this paper we enumerate current status of CCS projects worldwide, provide glimpses of CCS research in India and examine the opportunities. A brief summary of capacity building programmes on carbon capture and storage held with a focused goal of dissemination of knowledge among its stakeholders from industry and academia is also presented. SUSTAINABLE FARMING FOR SUSTAINABLE WORLD Chandra Kumar Sharma 40 Arjun Marg, DLF City, Phase 1, Gurgaon, Haryana email: conengr@gmail.com We wish to live in a green world. While we live, we pollute. We are 6.5 billion along with 56 billion animals. We must ensure the availability of food for everyone. This is possible through organic process which is here to rescue the mankind. In organic farming earnings are retained in the rural area. It is not transferred to the town/cities. The village becomes the centre of rural development. 57
