Thames Water announces sewage-to-biogas project in West London - Bioenergy Insight Magazine

Thames Water has shared that they will use sewage sludge to heat up houses in West London in the early part of this year after finishing its second gas-to-grid project at the Mogden Sewage Treatment Works. Thames Water revealed that the Deephams STW biogas was turned into biomethane to heat up homes in Enfield and served as the blueprint for Mogden's project. Mogden STW caters to more than 2 million customers and has the capability of supplying gas to 4,000 homes in West London. Sewage sludge is produced as a byproduct of the sewage treatment procedure and is digested to produce biogas. Mogden STW is capable of generating electricity by using the biogas via Combined Heat and Power engines. Gas supplier SGN is set to oversee the Gas-to-Grid plant, where they plan to take a portion of this biogas and upgrade it to export quality by filtering, scrubbing, and compressing it so it can be utilized as heating and cooking gas. Thames Water's Mogden and Deephams STWs have set a notable example of environmental stewardship and innovation, said Anna Boyles, head of catchment for Mogden. Thames Water has had to deal with criticism concerning the frequency of times that they discharge raw sewage into rivers. The company is working on plans to invest £18.7 billion in enhancing its network, which has found it challenging to accommodate sewage during heavy rainfall. Thames Water sustainability director Richard Aylard said that the company plans to execute work at more than 250 of its sites within the next five years, with each project costing millions of pounds. Thames Water has said that water bills could go up by £14 monthly to finance this project, and Bioenergy Insight has reached out to the company to ask if higher bills will cover the upcoming project.
