Hydrogen from Natural Gas. The Office of Energy Efficiency and Renewable Energy (EERE) and the Office of Fossil Energy (FE) are working to reduce the cost of producing hydrogen via steam methane reforming. EERE is focused on innovative technologies for distributed hydrogen production from natural gas and bioderived feedstocks.

In contrast, conventional coal combustion technologies capture the pollutants after combustion, which requires cleaning a much larger volume of the exhaust gas. This increases costs, reduces reliability, and generates large volumes of sulfurladen wastes that must be disposed of in landfills or lagoons.
Coal is typically burned to create steam, which is then piped at high pressure over a turbine, causing it to rotate, producing electricity. This steam electric system is a common one also used with other fuel sources, including oil, natural gas, geothermal, biomass, and even some solarfueled systems.

Technologies for critical environments. Coalfired power plants produce electricity by burning coal in a steam generator that transforms water into high pressure and high temperature steam. The steam flows through a series of steam turbines which drive an electrical generator to produce electricity.

Natural gas. Natural gas is the gas component of coal and oil formation. It is used in industrial and commercial heating and cooking, and, increasingly, to fuel electricity generation. In a compressed form, natural gas can also be used as a transportation fuel. Natural gas is either found mixed in oil or is released from coal.
Retaining existing coalfired stations for a few more years can therefore make their direct replacement by lowercarbon technologies more likely. ... Burning coal produces high levels of greenhouse gas emissions. Carbon Capture and Storage (CCS) technology could present a possible solution, although it has not yet been proven to work on an ...
Today, almost all of the hydrogen produced in the United States is used for refining petroleum, treating metals, producing fertilizer, and processing foods. The primary challenge for hydrogen production is reducing the cost of production technologies to make the resulting hydrogen cost competitive with conventional transportation fuels.
ENVIRONMENTAL PROBLEMS WITH COAL, OIL, AND GAS. ... As the rate of burning coal, oil, and gas escalates, so too does the rate of increase of carbon dioxide in the atmosphere. ... it is impossible to know what pollution control technologies will be effective in averting them. The oftenheard statement "we can clean up coal burning" involves a ...
Coalbed methane (CBM or coalbed methane), coalbed gas, coal seam gas (CSG), or coalmine methane (CMM) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries.
The first is that producing hydrogen from coal using commercially demonstrated technologies is competitive with that produced from natural gas. One of the key impediments to deployment of coal gasification for H 2 production is the lack of demonstrated integration of .
