Combined Heat and Power (CHP)

Improve your resilience and reduce energy spend with Combined Heat and Power (CHP), also known as cogeneration.

CHP is a highly efficient solution that captures the heat created through the electricity generation process, producing on-site heat and power simultaneously. A flexible and secure source of on-site generation, CHP has a typical payback period of 2-3 years and can cut your energy costs by up to 40%.

As the UK’s leading supplier and operator of Combined Heat and Power units, we have the expertise to design, deploy and maintain high performing units. We’re also developing a range of future-defining blended hydrogen and 100% hydrogen fuelled engines, making CHP a perfect option for all types of businesses and public sector organisations..

Benefits for your business

  • A highly efficient technology, by using waste heat, CHP plants can reach efficiency ratings in excess of 80%.
  • Assist with regulations and legislation, from BREEAM assessment to Part L of building regulations. 
  • Utilise captured heat, on-site for critical operations and processes.
  • Lower your electricity costs and reduce reliance on grid energy by generating your own electricity onsite.
  • Gain budget stability through predictable electricity costs and accurate forecasting of operating expenses.

Hydrogen fuelled CHP solutions

Our long-term partnership with combined heat and power (CHP) providers MTU and MAN continues to innovate around the future of this important on-site generation technology. We’re working to ensure our CHP solutions can meet the technical and commercial challenges of reaching net zero, with future-defining projects on blended hydrogen and 100% hydrogen fuelled engines.

We are developing a 20% blended hydrogen CHP solution across a large range of engines – with the switch achievable through minor changes to parts and software. Additional tests are being conducted in the 20-40% range to future-proof CHPs for potential adoption of national blended-hydrogen infrastructure.

Excitingly, our partnership with MTU is also already in single cylinder trials with 100% hydrogen fuelled CHPs – where it is anticipated engines electrical efficiency will operate at >40% – with an availability to customers post 2024.

How CHP works

CHP converts a single fuel into both electricity and heat in a single process at the point of use.

Single fuel for power and heat

Providing almost continuous operation, a CHP engine requires only a single fuel (typically gas) to function, simplifying your infrastructure requirements.

Electricity production

The engine, coupled to an alternator, generates power, which is then converted into usable electricity to meet on-site energy demands

Heat recovery

Simultaneously, heat is recovered from the engine exhaust, jacket and water/oil cooling circuit. The heat is then made available for redistribution on-site.
