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.
Taunton (/ˈtɔːntən/) is the county town of Somerset, England. It is a market town and has a minster church. Its population in 2011 was 64,621.[2] Its thousand-year history includes a 10th-century monastic foundation, Taunton Castle, which later became a priory.[clarification needed] The Normans built a castle owned by the Bishops of Winchester. Parts of the inner ward house were turned into the Museum of Somerset and Somerset Military Museum. For the Second Cornish uprising of 1497, Perkin Warbeck brought an army of 6,000; most surrendered to Henry VII on 4 October 1497.[3][4] On 20 June 1685 in Taunton the Duke of Monmouth crowned himself King of England in a rebellion, defeated at the Battle of Sedgemoor. Judge Jeffreys led the Bloody Assizes in the Castle's Great Hall.[5]
The Grand Western Canal reached Taunton in 1839 and the Bristol and Exeter Railway in 1842. Today it hosts Musgrove Park Hospital, Somerset County Cricket Club, is the base of 40 Commando, Royal Marines, and is home to the United Kingdom Hydrographic Office on Admiralty Way.[6] The popular Taunton flower show has been held in Vivary Park since 1866, and on 13 March 2022, St Mary Magdalene parish church was elevated to the status of Taunton Minster.[7]
