In addition to shale gas, other types of unconventional reservoirs include tight gas (low-porosity sandstones and carbonate reservoirs) and coal bed methane (CBM – gas produced from coal seams). Hydraulic fracturing is a known technology and has been used for at least 60 years. It has helped...
Interest in Botswana's gas potential is certainly rising, but its gas reserves take a very different form to those of most other countries in the Southern African Development Community (SADC) region, as they comprise coal bed methane gas. Gas brightens power outlook: Botswana could soon join th...
China has large resources of coalbed methane (CBM) and high coal production. A great deal of CH 4 is emitted from coal mines every year. More and more CH 4 will be emitted in future. It is necessary to do what we can to mitigate coalmine methane (CMM) emission in China. Chinese ...
Directors several years ago decided to expand the tent of renewables to include electricity produced by coal mine methane. Making use of methane: Aspen Skiing CO. finds unlikely ally in quest to reduce carbon footprint (c.) Methane from underground mines, which accounts for about 61% of coal...
reducing methane emissions in fossil fuel extraction; executing so-called transition solutions, such as a shift from coal to gas power; and implementing solutions, such as stopping deforestation, that both reduce emissions and positively impact na...
2) While improving physical property of coal seam around the well bore, reservoir fracturing brings about three disadvantages: ① it increases the formation pressure, which is inconsistent with the blowdown desorption gas production mechanism of coalbed methane, so this may cause large reduction in ...
Everyone has a carbon footprint: the amount of greenhouse gases produced from your everyday activities. Greenhouse gases include carbon dioxide, methane, nitrous dioxide, and chlorofluorocarbons. In the atmosphere, greenhouse gases contribute to thegreenhouse effect. ...
Globally, it has been evident that coal followed by gas is the largest source from which electricity gets produced. Which energy causes the least pollution? Solar energy causes the least air or water pollution or greenhouse gasses. Also, while in the process of harnessing and utilization, it le...
Water electrolysis is much cleaner if renewable electricity is used There is a better way: the method using electricity and water, where only hydrogen and oxygen are produced. This so-calledwater electrolysisis much cleaner than other production pathways if renewable electricity is used. Ideally, s...
What Is the Cheapest Form of Green Energy? The cheapest form of alternative energy is solar power, according to the International Energy Agency. In its 2020 World Outlook Report, the Agency found that photovoltaic solar energy is "consistently cheaper than new coal- or gas-fired power plants in...
