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.
Bridlington is a seaside town and civil parish in the East Riding of Yorkshire, England. It is on the Holderness part (Flamborough Head to the Humber estuary) of the Yorkshire Coast by the North Sea. The town is about 28 miles (45 km) north of Hull and 34 miles (55 km) east of York. The stream called Gypsey Race flows through the town and enters the North Sea at the harbour.
The Priory Church of St Mary and associated Bayle (or gate) are Grade I listed buildings on the site of an Augustinian Priory. As a sea-fishing port, the town is known for shellfish, and is the largest lobster port in Europe, with over 300 tonnes of the crustaceans landed there each year. It has been termed the "Lobster Capital of Europe".[3][4][5] Alongside manufacturing, retail and service firms, its main trade is summer tourism. It holds one of the UK's coastal weather stations.
