Summit Power
Summit Power Group is a Seattle-based energy development company, responsible for developing electric power plants and other energy-related facilities, which are primarily natural gas-fired and wind-powered, with solar power recently added. Summit does not develop conventional coal-fired power plants without carbon capture. Summit's prospective IGCC/ CCS projects include the Texas Clean Energy Project, the Renewable Energy Corporation Project in Montana, and surface facilities for underground coal gasification Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an ''in-situ'' gasification process, carried out in non-mined coal seams using injection of oxidants and steam. The product gas is brought t ...

Integrated Gasification Combined Cycle
integrated gasification combined cycle (IGCC) is a technology using a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ( syngas). It can then remove impurities from the syngas prior to the electricity generation cycle. Some of these pollutants, such as sulfur, can be turned into re-usable byproducts through the Claus process. This results in lower emissions of sulfur dioxide, particulates, mercury, and in some cases carbon dioxide. With additional process equipment, a water-gas shift reaction can increase gasification efficiency and reduce carbon monoxide emissions by converting it to carbon dioxide. The resulting carbon dioxide from the shift reaction can be separated, compressed, and stored through sequestration. Excess heat from the primary combustion and syngas fired generation is then passed to a steam cycle, similar to a combined cycle gas turbine. This process results in improved thermodynamic efficiency compared to co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Capture And Storage
Carbon capture and storage (CCS) or carbon capture and sequestration is the process of capturing carbon dioxide (CO2) before it enters the atmosphere, transporting it, and storing it (carbon sequestration) for centuries or millennia. Usually the CO2 is captured from large point sources, such as a chemical plant or biomass power plant, and then stored in an underground geological formation. The aim is to prevent the release of CO2 from heavy industry with the intent of mitigating the effects of climate change. CO2 has been injected into geological formations for several decades for enhanced oil recovery and after separation from natural gas, but this has been criticised for producing more emissions when the gas or oil is burned. Carbon capture and utilization (CCU) and CCS are sometimes discussed collectively as carbon capture, utilization, and sequestration (CCUS). This is because CCS is a relatively expensive process yielding a product which is often too cheap. Hence, car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Texas Clean Energy Project
The Texas Clean Energy Project (TCEP) was a project developed by Summit Power Group, Inc intended to build of the world’s first Integrated Gasification Combined Cycle (IGCC) clean-coal power plant, a type of carbon capture and storage facility, located near Odessa, Texas (coordinates 31° 44' 46" N, 102° 35' 42" W). Background According to Summit, the future Texas Clean Energy Plant was designed for 90% carbon capture, which was projected to be 2.7 million tons of carbon dioxide per year. If accomplished, this would be more than any other power plant of commercial scale operating anywhere in the world. As a result, the company declared that TCEP’s projected carbon emissions would be far lower than those of any existing fossil-fueled power plant. The potential carbon captured by the plant would be used for enhanced oil recovery in the West Texas Permian Basin. Summit was selected by the U.S. Department of Energy (DOE) to receive a $350 million cost-sharing award ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underground Coal Gasification
Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an ''in-situ'' gasification process, carried out in non-mined coal seams using injection of oxidants An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or " accepts"/"receives" an electron from a (called the , , or ). In other words, an oxi ... and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide. Ratios vary depending upon formation pressure, depth of coal and oxidant balance. Gas output may be combusted for electricity production. Alternatively, the gas output can be used to produce synthetic natural gas, or hydrogen and carbon monoxide can be used as a chemical feedstock for the production of fuels (e.g. diesel), fertilizer, explo ...
