Partnership to research the fuel-cell market, visiting manufacturers and installations in the UK and Germany, before carrying out further studies and computer thermal modelling to define suitability.

The fuel cell chosen, manufactured by UTC in the


US and supplied by Logan Energy, was chosen for its technical capability, commercial readiness and electrical and heat output. Technical support for the project from an experienced contractor, through the design and installation phase, was also a key factor. For TfL the choice of a fuel cell was logical, mirroring the technology used in the hydrogen buses TfL ran on

one of its routes in central London in 2006. A new fleet of fuel cell buses are due to hit the London streets this Autumn. The technology is also relatively mature in Europe and the US, with the number of installations running into the hundreds. As TfL found in its research, a wide range of building types are appropriate for fuel cells, which are present in hospitals, manufacturing plant, data centres and commercial buildings.


Ease of installation The fuel cell system at Palestra presented few installation challenges, says Stanton. ‘It was fairly straightforward, much the same as any building services installation such as a large gas boiler or conventional CHP, with connections to gas, water, electricity supplies and building monitoring systems all fairly standard. ‘The challenges were mainly around physically


installing a piece of plant in an existing building, and as usual with building services projects, integrating metering and building management systems.’ The installation was simplified by locating it at


ground-floor level in a reinforced-glass unit known as the ‘pod’ because of its organic curved shape. The opportunity to create a public display energy centre
