Biogas
Biogas is a gaseous renewable energy source[1] produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an anaerobic digester, biodigester or a bioreactor.[2] The gas composition is primarily methane (CH
4) and carbon dioxide (CO
2) and may have small amounts of hydrogen sulfide (H
2S), moisture and siloxanes. The methane can be combusted or oxidized with oxygen. This energy release allows biogas to be used as a fuel; it can be used in fuel cells and for heating purpose, such as in cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat.[3]
After removal of carbon dioxide and hydrogen sulfide it can be compressed in the same way as natural gas and used to power motor vehicles. In the United Kingdom, for example, biogas is estimated to have the potential to replace around 17% of vehicle fuel.[4] It qualifies for renewable energy subsidies in some parts of the world. Biogas can be cleaned and upgraded to natural gas standards, when it becomes bio-methane. Biogas is considered to be a renewable resource because its production-and-use cycle is continuous, and it generates no net carbon dioxide. From a carbon perspective, as much carbon dioxide is absorbed from the atmosphere in the growth of the primary bio-resource as is released, when the material is ultimately converted to energy.
Goole is a town, civil parish and inland port located at junction 36 off the M62 via the A614 and approximately 45 miles (72 km) from the North Sea at the confluence of the rivers Don and Ouse in the East Riding of Yorkshire, England, although historically within the West Riding of Yorkshire. Goole lies 19 miles (31 km) south of York and 29 miles (47 km) west of Hull.
According to the 2011 UK census, Goole parish had a population of 19,518,[1] an increase on the 2001 UK census figure of 17,600.[2] The port, which is the UK's furthest inland port, is highly versatile and capable of handling nearly 2 million tonnes of cargo per annum, making it one of the most important ports on the east coast of England.[3]
Goole is twinned with Złotów in Poland. Goole was informally twinned with Gibraltar in the 1960s; at that time, Gibraltar Court was named in Goole and Goole Court was named in Gibraltar.
