In the past, coal was converted to make coal gas, which was piped to customers to burn for illumination, heating, and cooking. High prices of oil and natural gas led to increased interest in "BTU Conversion" technologies such as gasification, methanation and liquefaction.
Underground product gas is an alternative to natural gas and potentially offers cost savings by eliminating mining, transport, and solid waste. The expected cost savings could increase given higher coal prices driven by emissions trading , taxes, and other emissions reduction policies, e.g. the Australian Government's proposed Carbon Pollution ...
The typical gaseous carbonaceous feedstocks used are natural gas and reducing tail gas, while the typical solid carbonaceous feedstocks used are coal and biomass. The feedstocks are partially oxidized to generate syngas using metal oxide oxygen carriers as the oxidant. The reduced metal oxide is then oxidized in the regeneration step using air.
Aug. 13—PETERSBURG — The Petersburg Power Generation Station has a new lease on life following an announcement by AES of a $1.1 billion investment to convert the plant from coal to natural gas.
In the United Kingdom the discovery of large reserves of natural gas, or sea gas as it was known colloquially, in the Southern North Sea off the coasts of Norfolk and Yorkshire in 1965 [8] [9] led to the expensive conversion or replacement of most of Britain's gas cookers and gas heaters, from the late 1960s onwards, the process being completed ...
Here are three companies making the switch from coal to natural gas. Duke EnergyDuke Energy is hard at work on a $9. Source: Dominion Resources. The energy world is changing fast, and utilities ...
H. R. Milner Generating Station is a coal and natural gas-fired power station owned by Maxim Power, located near Grande Cache, Alberta, Canada. H.R. Milner is currently undergoing conversion from coal to natural gas as the power station's fuel source and is expected to be complete by April 2020. [1] [2]
Substitute natural gas (SNG), or synthetic natural gas, is a fuel gas (predominantly methane, CH 4) that can be produced from fossil fuels such as lignite coal, oil shale, or from biofuels (when it is named bio-SNG) or using electricity with power-to-gas systems.
