Carbon free electricity – DRD Power Ltd
DRD Power Ltd has developed an innovative and cost effective technology that converts waste heat from manufacturing processes into carbon free electricity to help achieve decarbonisation and reduce operating costs. A 132kW generator has been designed and installed at Huntsman Tioxide Pigments at Hartlepool. The electric power generation unit utilises the low temperature process waste heat at 90°C and converts this directly into carbon free electricity. The unit reduces CO2 emissions by 400 tonnes/year and generates electricity worth £80,000/year.
DRD Power won a Shell Springboard award for this carbon reducing technology. The design of the unit is based on modern refrigeration technology and does not use any flammable or toxic substances. The modular power generation units are available in a range of sizes from 10kW – 200kW.
The technology can be applied to a wide range of process sectors including chemicals, refineries, distilleries, iron & steel, power generation, CHP engines, landfill site gas engines, anaerobic digestion plants, cement, glass & ceramics, waste to energy plants, hazardous waste incinerators, thermal oxidisers, crematoria, etc.
In the case where electric power generation is combined with biomass boilers used for process heating and in hotels, sports centres, spas, horticulture/garden centres, these usually qualify for the highly lucrative CHP–RHI (Combined Heat & Power – Renewable Heat Incentive) payments which are index linked and payable for 20 years.
We encourage our partners and supporters to share their examples of good practice in tackling the climate emergency, reversing ecological collapse and delivering a just transition. NEECCo does not undertake to quality assure these case studies, and inclusion of a case study on this website does not imply endorsement of the project by NEECCo or by its partners.
Some case studies will feature organisations who are involved in fossil fuel industries, or who are open to challenge on other aspects of their performance in relation to our objectives. NEECCo recognises that if we are to reach our ambitious objectives, all organisations and individuals within the north east will need to adapt their behaviour and actions. We want our case studies to encourage this process. Our commitment to achieving a just transition from a carbon-based economy to a green economy requires us to encourage positive steps wherever they are to be found.
We are interested in your views on the case studies so please choose to like/ dislike each case study.
