Natural gas in the United States natural gas and natural gas liquids. The exploration for and production of natural gas and petroleum form a single industry, and many wells produce both oil and gas. Because of the greater supply, consumer prices for natural gas are significantly lower in the United States than in Europe and Japan. The low price of natural gas, together with its smaller carbon footprint compared to coal, has encouraged a rapid growth in electricity generated from natural gas. Between 2005 and 2014, US production of natural gas liquids (NGLs) increased 70%, from 1.74 million barrels per day in 2005 to 2.96 million
Direct carbon fuel cell Direct carbon fuel cell A Direct Carbon Fuel Cell (DCFC) is a fuel cell that uses a carbon rich material as a fuel such as bio-mass or coal. The cell produces energy by combining carbon and oxygen, which releases carbon dioxide as a by-product. It also called coal fuel cells (CFCs), carbon-air fuel cells (CAFCs), direct carbon/coal fuel cells (DCFCs), and DC-SOFC. The total reaction of the cell is C + O → CO. The process in half cell notation: Despite this release of carbon dioxide, the direct carbon fuel cell is more environmentally friendly than traditional carbon burning techniques.
