Heat from sewers eyed to warm UK parliament

LONDON: London landmarks including the UK parliament could be warmed by low-carbon heat powered by the River Thames, the London Underground train system and even the sewer network under new government plans. Around 1,000 buildings could be in line to receive the alternatively sourced warmth.

Under the plans to develop the UK’s biggest heat network to provide decarbonised heat, pipes designed to carry excess heat taken from various sources would power hot water and central heating systems in the Westminster area of central London, where parliament is located. The 1.0-billion ($1.3-billion) low-carbon heating infrastructure project — initiated by Westminster Council and the government’s Department for Energy Security and Net Zero (DESNZ) — aims to harness waste heat from a small area and distribute it locally.

Such networks are considered the cheapest way to decarbonise compared to each building having its own air source heat pump. They are expected to play an increasingly important role in supplying UK energy over coming years as the government attempts to wean the country’s power grid off fossil fuel energy sources by the end of the decade.
