A British engineering firm is offering a ground breaking technology that allows its clients to generate electricity as well as heat from biomass boilers – while significantly increasing financial returns.
These returns could approach as much as £350,000 per year* for a 1.5MW biomass boiler (see chart, above).
Heliex Power manufactures and supplies patented steam expander systems that generate electricity and thermal energy from the waste heat and process steam often found in factories, distilleries and the agricultural industry.
The company is headquartered in East Kilbride, near Glasgow, and currently employs 26 people.
When integrated with a steam generating biomass boiler, the Heliex system creates a combined heat and power (CHP) solution, resulting in a significantly shorter payback period than if a biomass boiler were installed alone.
A UK client with an onsite 3.5MW steam raising biomass boiler has recently installed a Heliex system. It is now generating 100kW of electricity, which is used to power its plant room and is eligible for financial incentives.
Dan Wright, Chief Executive, Heliex Power, said: “Our award-winning technology can be used in a number of applications – but biomass is currently proving extremely popular with our clients as it allows them to really maximise their investment.
“Utilising a biomass boiler to generate electricity – as well as heat – provides a reliable supply of low cost electricity that can be used on-site or sold back to the grid and is eligible for payments through Renewable Obligation Certificates.
“Meanwhile payments from the Renewable Heat Incentive (RHI) scheme are much increased – in many cases doubled for the duration of the scheme.
“We typically expect a return on investment in a Heliex System of just under one year, which is exceptional.”
Introduced by the government in 2011, the RHI scheme offers financial incentives for the installation of heat generating technologies such as biomass boilers. Payments are guaranteed for 20 years, paid quarterly, and depend on the type of technology installed and how much heat is generated. ROCs are a financial support mechanism for UK renewable electricity projects.
Wright added: “Based on a steam screw expander, the Heliex System is a novel rotary device that recovers energy from different heat sources. Current clients include chemicals manufacturers, steel mills, glass plants and farms across Europe, although there is considerable potential in other industry sectors too.”
