Advantages
Our Competitive Advantage
Unlike most competing technologies, we have designed specifically with the typical cogeneration application in mind. Compared to Stirling cycle engines, our system is light and compact for ease of home installation. And unlike internal combustion engines, it is inherently quiet, has low exhaust emissions and requires almost no maintenance. In contrast to fuel cells, the technology is simple and affordable and ready for volume manufacture using conventional processes. We understand that home heating boiler replacement is often a distress purchase. It is thus critical that our system can slot straight in where the boiler came out. And even more importantly, it must cost not much more than a conventional boiler - otherwise the payback time will be unattractive. Our system meets these critical requirements with its simplicity. Our innovative approach to Rankine cycle engine design eliminates many moving parts and replaces them with electronic control and actuation. Our system uses water as the working fluid, basically making it a small steam engine, eliminating issues with exotic working fluids that require hermetic sealing and periodic replacement. High efficiency ensures that it generates enough electricity to pay for itself rapidly. Our domestic unit will produce 2.5kW of electricity whilst producing 11kW of heat, operating at an overall efficiency of over 90% (based on higher heating value). Even more importantly, unlike almost all other competing technologies, our system operates at high efficiency at part load. This is important, as heating systems are generally sized for the coldest day, so operate at part load most of the time.
Our technology is protected by a comprehensive intellectual property protection strategy. This includes patents that cover core aspects of the heat engine technology and the control system that allows us to connect directly to the grid without the need for a costly inverter. We also have one of the best technology development teams in the business. Our technical team has a proven track record at developing and commercializing technology
