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 ...

Energy revolution: This is how intelligent technology supports upheaval
It is no longer a secret that fossil fuels such as hard coal and lignite are harmful to the environment. Germany would like to become greener and continue to rely on renewable energies as a result of the energy revolution. Intelligent technology in particular should support people in this and make power generation more eco-friendly. The problem of climate change Phasing out nuclear energy ...

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 ...

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 ...

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 ...

CSP technology advances crucial for cutting costs in South Africa
With some of the highest levels of Direct Normal Irradiance (DNI) in the world, CSP is positioned to play an immense role in South Africa’s energy landscape. Currently, four CSP technologies are being promoted internationally, parabolic trough, power tower, fresnel and dish stirling, but with the lack of operational data in South Africa the industry is still evaluating the suitability of ...

Efficiency analysis of coal-based thermal power generation in India during post-reform era
Coal-based thermal power stations are the leaders in electricity generation in India. This study employs the stochastic frontier production function methodology for panel data to measure the technical efficiency (TE) of coal-based thermal power plants in India during 1994-1995 to 2001-2002. Efficiency varies widely across plants and regions, while the TE is time-invariant. The average TE is ...

Value of nuclear power in the global energy system
With a global energy model which finds the minimum cost energy system over the time range of 1995-2055, the value of nuclear power is analysed. The model incorporates detailed descriptions of energy conversion technologies. For nuclear technologies, light water reactors and fast breeder reactors are taken into account with fuel cycle options. Major findings are: 1) the maximum introduction of ...

Fact Sheet: U.S. electricity markets increasingly favor alternatives to coal
The U.S. electric power system is gradually shifting toward cleaner forms of generation. One sign of this transition is the declining use of coal for electric power production. In 2011, use of coal for U.S. power generation dropped to its lowest level in more than a decade, according to the federal government’s independent U.S. Energy Information Administration (EIA). In fact, the EIA ...

Simplistic understanding of transitioning to renewables in Colorado
We have all heard that renewables are now cheaper than coal or gas, especially after the Xcel bid that was reported in 2018, with PV with battery storage at a median price of $38/MWh (3.8 C/kWh) and Wind at $19.3/MWh (1.9 c/kWh). If this is true, why don't we just replace everything with wind and solar right now? It is, of course, a bit trickier than that. These prices, listed above, are for ...

A just transition from coal to renewable energy in the Hunter Valley of New South Wales, Australia
The Hunter Valley, New South Wales, Australia is one of the world's climate change hot-spots. It is where 40% of Australia's electricity is generated from five coal-fired power plants, and is the source of 100 million tonnes of black coal exported annually to the global markets. A growing number of local residents of the Hunter Valley are questioning the sustainability of the region's coal ...
