National Grid is forging ahead with 14 pilot schemes to generate power from gas pressure as it moves through the supply network. Natural gas is driven through pipes under pressure, which must be reduced before being delivered to users. This could be achieved using turbine generators, which would generate electricity. National Grid is in a joint venture with geo-pressure energy company 2OC. Investment in the first eight sites will total up to £60M. The first two will be near the 2012 Olympic site in east London.
