OakTec is developing a range of industrial engine technologies that are optimised to produce the best combination of fuel efficiency with ultra low exhaust emissions to benefit air quality and reduce CO2 output. Our innovations in digital engine control and combustion strategies deliver a step change in the performance of small engines and bring gas engine technology into the 21st century. The small engine products we develop will be price competitive with high quality diesels of equivalent performance and will comply with all current global emission regulations. Products now in development for customer trials in our CAGE generators range from 2-50kW outputs. These trials will use the latest bioLPG fuels supplied by project partner Calor.
OakTec is developing engine technologies to overcome the many challenges of achieving efficient and reliable combustion of biogas in small engines. Innovation and R&D supported by the UK government through the Energy Catalyst program has now resulted in very effective solutions that enable an engine supplied with low quality biogas fuel containing around 50% CO2 to deliver the same performance as a diesel engine of equivalent capacity. The engines connect directly to the anaerobic digestor that produces the fuel. OakTec is working in partnership with Sistema Bio, global market leader in micro AD, to demonstrate world class biogas generators built in the UK by Sutton Power Engineering on off-grid farms in Kenya.
In response to the challenges set out in achieving a zero carbon economy OakTec built and tested three prototype hydrogen engines in 2019 using adaptations of our gas engine technology portfolio. The engines were tuned to eliminate all harmful emissions including NOx and one engine was successfully demonstrated powering a small vehicle. Hydrogen is a key direction for future development of OakTec’s gas engine technology platforms.
