Power generated from methane gas in disused mines in England
Type HOFGAS®-IPM/C 2500 Performance 2’500 Nm³/h / 520mbar dP Location England (GB) Situation Mine gas is released when coal is extracted. This gas is sourced not only from working coal mines but also from those that were closed down long ago. Because large quantities of coal remain in the mine after it has ceased production, mine gas is released afterwards. The high proportion of ...

Coal sorption characteristics and coal surface tension
Underground coal mining in the Bulli Seam of Sydney Basin, Australia encounters the problems of coal and gas outburst as the coal contains high concentration of CO 2 , where certain parts of the seam have been found to be especially hard-to-drain. In order to better understand these problems, the influence of temperature and moisture on sorption capacity of bituminous coal was investigated at ...

Toxicity of sediments potentially contaminated by coal mining and natural gas extraction to unionid mussels and commonly tested benthic invertebrates
Sediment toxicity tests were conducted to assess potential effects of contaminants associated with coal mining or natural gas extraction activities in the upper Tennessee River basin and eastern Cumberland River basin in the United States. Test species included two unionid mussels (rainbow mussel, Villosa iris and wavy‐rayed lampmussel, Lampsilis fasciola, 28‐d exposures), and the commonly ...

The bottom line series: Carbon taxes
Climate policy debates often feature discussions about the role of a carbon tax, either as an alternative or a supplement to a cap-and-trade program. This fact sheet describes the similarities and differences between the two policy approaches and answers other common questions about a tax on carbon. What is a carbon tax? A carbon tax is a fee imposed on fossil fuels, and other primary products ...

Bolivar wastewater treatment plant cogeneration facility to be Installed by Clarke Energy - Case Study
The Bolivar Wastewater Treatment Plant (WWTP) is the largest wastewater treatment plant in the Adelaide region, processing almost 70% of Adelaide’s metropolitan wastewater. The South Australian Government has approved a $25.8 million project for SA Water to optimise the energy utilisation on the site. This project will provide a major upgrade to the WWTP power supply by the installation of ...

How do we create an ethical grid?
So much of what’s discussed in offices these days – and forever really – focuses on this: What’s best for the company? How do we increase profits? That’s totally understandable, given that a primary responsibility of any for-profit enterprise is to benefit its owners and investors. Still, as individuals, and I would argue, as part of the capitalist system, we have ...

Outlook palls for fossil fuel investments
Like most central bank governors, Mark Carney, the Governor of the Bank of England, chooses his words carefully. So the financial community – and government policy makers − sat up and took notice earlier this month when Carney, addressing a World Bank seminar on corporate reporting standards, said he was concerned about investments in fossil fuels. “The vast majority of ...

Generation using gas-fuelled engines in South Africa – an overview
Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, cogeneration and, even, trigeneration units to optimise energy utilisation in the fuel ...

Methane De-Gassing in a Coal Mine
Aardvark Packers are used in coal mines to enhance operations and safety. They are used to de-gas, vent and direct methane gas away from new mine faces prior to mining to ensure as safe work environment. A typical 4-1/2” diameter hole in the face or in the ribs will be drilled. Sometimes, gel is injected into the borehole to isolate the gas. An Aardvark inflatable packer is inserted into ...

Coallercoaster: As U.S. coal production drops, international demand rises
According to a recent report from the U.S. Energy Information Administration, the number of new and reactivated coal mines in the U.S. hit a 10-year low in 2013 — down nearly 67 percent from 2008. Total coal production in the U.S. was also down during the same time period. The drop was driven by a number of factors, including regulatory pressure, reduced investment, shifting demand toward ...

Building New Industries and Creating New Jobs in a Plan B Economy
Building a new economy, one that can sustain economic progress, involves phasing out old industries, restructuring existing ones, and creating new ones. This new economy will be powered by renewable sources of energy, will have a more diverse transport system--relying more on rail, buses, and bicycles, and less on cars--and will recycle everything. For example, coal use will be phased out, ...

Huge success in photovoltaics through 20 years of the EEG
20 years EEG. For many this is a reason to celebrate, for opponents it is a reason to swear. No matter what the respective EEG assessment looks like: The success of the EEG in photovoltaics is enormous and will change the world for good: Solar power is already the cheapest energy source in the world and is readily available. Blog together with Carsten Pfeiffer, who was actively involved in the ...
