Storing carbon: options for liability risk management, financial responsibility
The authors of this article say the technical complexity, economic impacts, social demand, and political challenges underpinning the deployment of carbon capture and storage technology to reduce greenhouse gas emissions from coal-fired electric power generation are daunting, but not unprecedented. In response to these challenges, the authors recommend the creation of a new “federal government ...

A long year in the life of the US coal industry
With concerns about climate change mounting, the era of coal-fired electricity generation in the United States may be coming to a close. In early 2007, a US Department of Energy report listed 151 coal-fired power plants in the planning stages in the United States. But during 2007, 59 proposed plants were either refused licenses by state governments or quietly abandoned. In addition, close to 50 ...

Difficult Complex Decisions For Coal-fired Power Plant Operators
Changing fuel prices, government regulations and technology all combine to make decision making difficult for operators and developers of coal-fired power generation facilities around the world. Power plant designers in developing countries face new local environmental regulations plus additional requirements stipulated by lenders such as the World Bank. In the developed world, the regulations ...

King Coal’s Climate Challenge
Coal is emerging as a major topic of conversation at the United Nations climate-change negotiations currently taking place in Warsaw – and rightly so. Indeed, it is a discussion that the world needs to have. The latest findings of the Intergovernmental Panel on Climate Change conclude that we are quickly using up our carbon “budget” – the amount of carbon that we can ...

Water Risks on the Rise for Three Global Energy Production Hot Spots
Energy runs on water. In fact, among industries, the global energy sector is the world’s largest water user. Almost all forms of energy production and power generation depend upon water for their operations. This tension causes stress in both the energy and water worlds. Three-quarters of energy respondents to a 2012 CDP Global Water Survey confirmed that they experienced water-related ...

CC-88 targets China’s oldest power plants for energy efficiency and pollution control
China made a “huge” move to convert it’s developing nation to a world leading economy. The “huge” move made was bringing electricity to the 100% of it’s 1.3 billion people. Now consumerism is taking hold of China’s 1.3 billion inhabitants. 1.3 people are buying rice cookers, refrigerators, TVs and Computers. China’s energy needs are at an all time ...

Closing the door on building new coal-fired power plants in America
Community opposition, legal challenges, and financial uncertainty over future carbon costs are prompting companies to rethink their plans for coal. Since the beginning of 2007, 95 proposed coal-fired power plants have been cancelled or postponed in the United States--59 in 2007, 24 in 2008, and at least 12 in the first three months of 2009. This covers nearly half of the 200 or so U.S. coal-fired ...

Cenospheres - Case Study
The problem: A cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, typically produced as a byproduct of coal combustion at thermal power plants. On average 0.5% of the fly ash generated in a coal fired power station boiler are Cenospheres. When fly ash is wet discharged in to ash ponds/lagoons cenospheres float on the water ...

Pressurised pulverised coal combustion ? a coal-based combined-cycle state of the cooperative project: cleaned flue gas matches specifications for use with gas turbines
A high efficiency of 60% in a combined-cycle power plant technology with fuels like gas or light oil is estimated to be achievable. On the other hand existing conventional coal-fired power plants based on steam generation have an efficiency of about 40?45%. A huge potential of improvement in efficiency could be achieved by the implementation of a simple and cost-effective technology: PPCC, a ...

Commercial Demonstration of a PEM Fuel Cell for Power Generation
The chlor-alkali industry, one of the largest chemical industries in India and growing at an annual rate of 3.3%, is expected to grow along with the growing Indian economy. This MW size proton-exchange membrane (PEM) fuel cell product captures hydrogen produced in the chlor-alkali industry to create on site electricity and provide plant operators up to 20% of electricity savings. The electricity ...

Even rebels like efficiency
Clean energy advocates favor a federal requirement that a certain amount of our electricity come from green sources, a concept known as a portfolio standard. No year in history has offered more promise for the policy. President Obama is pushing for at least 10% of our electricity to come from renewable sources by 2012, and 25% by 2025. Congressional Democrats have obliged by putting several ...

The international coal industry: comments on the paper by David Humphreys and Keith Welham
This comment discusses in more detail one of the primary messages in the paper by David Humphreys and Keith Welham, namely the fundamental shift in the steam coal industry away from security of supply concerns and national focuses towards an international and cost-driven perspective. On the supply side, this has meant an increased focus on mining productivity. By consulting recent research, this ...
