Largest fuel cell in UK to generate greener energy at Transport for London

Transport for London (TfL) has inaugurated the UK’s largest hydrogen fuel cell housed in a building, at the Palestra building in Southwark. The 200 kW combined heat and power (CHP) power plant – which features a UTC Power PureCell® 200 phosphoric acid fuel cell unit – will generate cleaner, low-carbon energy onsite, with significant savings on energy costs.

Transport for London has installed the £2.4 million (US$3.7 million) CHP plant, including the UTC Power fuel cell system, at the Palestra building. It is estimated that the fuel cell power plant will cut carbon emissions by up to 40 percent and generate £90 000 (US$140 000) in annual cost savings.

A permanent multimedia exhibition display has been created, to communicate the benefits of hydrogen and the fuel cell to people passing and visiting the building. The display will be powered by the energy generated onsite.

The hydrogen fuel cell system, funded by the £25 million (US$38.7 million) TfL Climate Change fund, will provide electricity, heating, and cooling to the building. In addition, the hot water supply will be heated by the fuel cell.

At times of peak energy use, the building will generate a quarter of its own power, rising to 100 percent off-peak. The waste heat from power generation will be pumped into a unit on the roof, which will work to keep the building cool and supplement the building’s six electric chillers.

TfL also jointly announced with the London Development Agency (LDA) that all their head office buildings will participate in the 10:10 campaign, with the aim of reducing carbon emissions by 10 percent, and providing an estimated £400 000 (US$620 000) in annual cash savings.
