Energos’ plant in the Isle of Wight has become the ‘first’ gasification facility to receive Renewable Obligation Certificates (ROCs).
Ofgem gave the facility full accreditation in October but Energos has now taken receipt of the ROC payment for the months October to December 2010.
An agreement on the fuel measurement system had to be reached before Ofgem would accredit the facility. This involved measuring the level of biomass content in the fuel and the gross calorific value (GCV) of the synthetic gas.
Ofgem will continue to issue the plant with ROCs, which approached an auction value of £50 in March.
Energos managing director Nick Dawber said: “Now we have reached an agreement with Ofgem and are receiving ROCs, we can press ahead with developing several small scale projects in the UK. Planning consent has been granted for seven more energy recovery facilities using Energos technology.”
ROCs are not available to incineration schemes, unless they generate both heat and electricity and meet CHPQA requirements, which is a quality assurance for combined heat and power. They are available to gasification and pyrolysis schemes as Advanced Conversion Technologies (ACT).
Energos’ gasification facility uses ACT. Fuelled on refuse-derived fuel, the biodegradable energy content has to be measured rather than being ‘deemed’ because it has been pre-treated. It was also the first plant to install a continuous calorimeter to measure the GCV of the syngas. Currently, the plant is producing in excess of the 4MJ/m3 GCV required for double ROCs.
