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 ...

Crypto`s quest for power - bridging the crypto-mining and natural gas sectors
The last few months have changed a great many things in a great many ways. Industries of all kinds have been struggling in ways that they could not have foreseen, but one sector that seems to continue to thrive is crypto-mining and the crypto asset market. The challenge is that as crypto [or digital assets] rise in prominence and value, its appetite for power grows. If only there was a potential ...

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 ...

Green Investment Bank - good or bad for the Carbon Trust?
The response to the setting up of a new Green Investment Bank has raised questions over the future of the Carbon Trust, but everyone seems happy - even the Carbon Trust. FTSE launched new indices that rate the carbon strategies based on their exposure to climate change-related risks, reports Envido. FTSE Group this week launched new indices designed to help investors track firms" ability to ...

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 ...

Industrial decarbonisation: How to reduce your carbon footprint?
Decarbonisation is a crucial stake for all companies, given that the industrial sector is responsible for 19% of greenhouse gas emissions in the UK. In 2021 it was directly responsible for emitting 9.4?Gt of CO2, accounting for a quarter of global emissions. While progress has been made in this sector since the 1990s, the manufacturing industry (part of the industrial sector) alone produced 78.4 ...

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 ...

Comparison of Gas and Water Pycnometry of Coal Mine Wastes
Coal mine washery wastes comprise two major components whose specific gravities differ markedly. Consequently, their specific gravity is much more variable than that of natural soils and is determined relatively frequently. The specific gravity of coal mine wastes is determined more rapidly and efficiently by gas pycnometry than by water pycnometry. However, the two methods give significantly ...

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 ...

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 ...

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 ...

On-Vehicle Exhaust Gas Cooling in a Diesel
ABSTRACT A diesel emissions control system built and tested on an industrial forklift truck is described. The system utilizes a pleated media type diesel soot filter. The temperature limit of the filter material is well below the temperature of the exhaust gas. Therefore, cooling of the exhaust gas is necessary. A finned-tube heat exchanger is included in the system to cool the exhaust gas to ...
