Biogas CHP unit for small scale anaerobic digestion claims 5.7m ROI over 20 years
A sub 200kwth combined heat and power (CHP) unit has been launched by ENER-G for small scale anaerobic digestion, which the company claims maximises financial returns on both the highest rate Renewable Heat Incentive (RHI) and Feed in Tariffs (FIT). Designed for smaller farms and dairies, the E200 biogas CHP unit provides a thermal output of 195kWth (qualifying for a RHI of 7.5p per kWth), together with an electrical output of 205kWe - at a total efficiency rating of 77.1%. The company claimed this unit will “accelerate the pay back on investment - making anaerobic digestion feasible for smaller farms and other sites”. A MAN engine is used in the unit, with the cooling level of exhaust gases being reduced to achieve a sub 200kWth heat output. In a press release, the company said: “At current rates, a typical farm or dairy operating the E200 on a 24-hour cycle at 92% availability would receive annual payments of £167,361 for FITs and £117,866 for RHI - amounting to a total guaranteed 20-year income of up to £5.7 million.” Laurence Stephenson from ENER-G said: "Many pre-accredited anaerobic digestion projects are stalling because of finance issues, particularly due to FIT digression. But with guaranteed higher rate returns from RHI, a typical small scale anaerobic digestion project should offer a payback within four years, providing a guaranteed profit stream thereafter.” ### Read more 48,000 tpa Anaerobic Digestion plant in Bucks earns PAS 110 for digestate Biomethane cleaning plant £2.3m investment at Gloucestershire anaerobic digestion project Food waste throughput could be doubled at AD biogas plants with autoclave pre-treatment
