 A unique feature of the building was a sophisticated energy system, developed by TNEI Services Ltd. and the Pure Energy Centre, which both reduced the electricity demand of the operation of the building and the activities of its occupiers from the network and which will has the capacity to export electricity to the local electrical network.Electricity can be generated from a 225 kW wind turbine at the edge of the site, attached to an electrolysis unit which can convert some of the wind energy into hydrogen.The hydrogen is then be stored in composite cylinders and fed to a 30 kW fuel cell when required to provide electricity to the building during the day and potentially supplying the National Grid with surplus power.
