Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of natural gas.. Common ways for refining synthetic fuels include the Fischer–Tropsch conversion, [better source …
Technologies for hydrogen (H 2) production fall into three main categories:. Thermal Processes: Some thermal processes use the energy in various feedstocks (natural gas, coal, biomass, etc.) to release the H 2 that is part of their molecular structure. Other thermal processes known as thermo-chemical processes use heat in combination with a closed chemical cycle to …

Shale gas was first extracted as a resource in Fredonia, New York, in 1821, in shallow, low-pressure fractures. Horizontal drilling began in the 1930s, and in 1947 a well was first fracked in the U.S.. Federal price controls on natural gas led to shortages in the 1970s. Faced with declining natural gas production, the federal government invested in many supply …
Carbon dioxide (chemical formula CO 2) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas.It is a trace gas in Earth's …
2003: Core Energy/South Chester Gas Processing Plant in Michigan. Carbon dioxide is captured by Core Energy from natural gas processing for EOR in northern Michigan with over 2 million MT captured to date. 2008: Snøhvit Carbon Dioxide Storage offshore of Norway. Carbon dioxide is captured from an LNG facility on an island in the Barents Sea.
The world's electricity supply is dominated by fossil fuels. Coal is by far the biggest source, supplying 37% of electricity; gas is second and supplies 24%. Burning these fossil fuels for electricity and heat is the largest single source of global greenhouse gases, causing 30% of global emissions. 3 The chart here shows how the electricity prices from the long-standing …
The health and environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products.In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste products annually, including fly ash, bottom ash, and flue-gas …
There are the block of gas producing boreholes and the block of air-given boreholes and the block of coalbed methane recovery boreholes. The essence of this unconventional …
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of …
A 2011 MIT study calculated that increased utilization of existing natural gas power plants to displace coal-fired power could reduce the electric sector's carbon emissions by 22 percent in the near term . Natural gas' contribution to electricity generation is growing rapidly: from only 17 percent in 2001 to 30 percent in 2012 .
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to …
Learn how emissions reductions, advancements in fuels and fuel economy, and working with industry to find solutions to air pollution problems benefit human and environmental health, create consumer savings and are cost effective.

In addition to gasification, the main thermal process technology which is available for production of H 2 is steam reformation of natural gas. It is a well established technology that …
Coal is the most abundant fossil fuel on the planet, and widely used as the source of energy in thermal power stations and is a relatively cheap fuel. Coal is an impure fuel and produces more greenhouse gas and pollution than an equivalent amount of petroleum or natural gas. For instance, the operation of a 1000-MWe coal-fired power plant results in a nuclear …
The concept of sustainable development can be traced to the energy (especially fossil oil) crisis and environmental pollution concerns of the 1960s and 1970s. The Rachel Carson book, "Silent Spring", published in 1962, is considered to be one of the first initial efforts to describe sustainable development as related to green building. The green building movement …

Fracking (also known as hydraulic fracturing, hydrofracturing, or hydrofracking) is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create …
