Industrial Energy Efficiency
Optimising energy use, reducing waste, and cutting emissions in industrial operations.
Overview
Industrial facilities are among the largest energy consumers in the economy, with significant potential for efficiency gains. Clarke Energy delivers integrated low carbon energy solutions that connect power generation, heat recovery, cooling, and process systems to maximise efficiency and minimise waste.
By combining high efficiency generation technologies with process integration and advanced controls, we help manufacturers, processors, and large commercial sites reduce operating costs, improve reliability, and meet carbon reduction targets without compromising production performance.
Combined Heat and Power (CHP) Integration
Clarke Energy’s CHP systems produce electricity on site while capturing waste heat for process use, significantly reducing reliance on separate boilers and grid power.
Benefits:
• Total system efficiencies above 80%
• CO₂ reductions of up to 30% compared to separate heat and power (and near zero with renewable fuels)
• Increased energy resilience with on site generation
Trigeneration for Integrated Power, Heat & Cooling
Where simultaneous cooling demand exists—such as in food processing, pharmaceuticals, or electronics—trigeneration (CCHP) can convert recovered heat into chilled water.
• Reduces electrical load on chillers
• Improves system efficiency and reduces OPEX
• Maintains process reliability during grid disturbances
Electrical and Thermal Microgrids for Industry
Clarke Energy designs industrial microgrids that integrate electrical and thermal energy systems into a coordinated, self sufficient network.
Electrical Microgrids
Thermal Microgrids
Electrical Microgrids
• Combine on site generation (CHP, renewable gas engines, solar PV) with Battery Energy Storage Systems (BESS)
• Provide island mode and black-start operation during grid outages to maintain production
• Enable peak shaving and demand response participation for cost savings
• Optimise renewable integration while ensuring stable voltage and frequency
Thermal Microgrids
• Distribute recovered heat or chilled water across multiple facilities or processes
• Can connect to district heating or district cooling networks for broader decarbonisation impact
• Reduce reliance on individual boilers and chillers, improving system efficiency and lowering emissions
• Enable heat cascading, matching high and low temperature heat streams to specific process needs
By linking electrical and thermal flows within a microgrid, industrial sites can maximise energy reuse, reduce emissions, and improve resilience while lowering total operating costs.
Smart Controls & Process Integration
We deploy advanced control systems and SCADA platforms to ensure optimal performance:
• Load following operation to match generation to process demand
• Peak shaving to lower electricity costs and demand charges
• Real time performance monitoring for maximum efficiency
Contribution to the UN Sustainable Development Goals (SDGs)
Clarke Energy’s industrial energy efficiency solutions support:
• SDG 7 – Affordable and Clean Energy: Delivering efficient, clean energy to industry
• SDG 9 – Industry, Innovation and Infrastructure: Modernising plants with sustainable energy systems
• SDG 12 – Responsible Consumption and Production: Maximising energy reuse and reducing waste
• SDG 13 – Climate Action: Cutting emissions from industrial processes
Waste Heat Recovery & Waste Heat to Power (WH2P)
Renewable Fuels for Industrial Decarbonisation
Waste Heat Recovery & Waste Heat to Power (WH2P)
Many industrial processes produce surplus heat that is often vented to atmosphere. Clarke Energy designs recovery systems to:
• Preheat feedwater for steam generation
• Supply hot water or space heating
• Drive absorption chillers for process cooling
• Integrate with heat pump systems
Recovering and reusing waste heat increases overall efficiency and lowers emissions.
Renewable Fuels for Industrial Decarbonisation
Our systems are fuel flexible and can operate on:
• Biogas from anaerobic digestion of organic waste
• Biomethane (RNG) upgraded from biogas for grid injection or on site use
• Green hydrogen from renewable electrolysis and blue hydrogen integrating carbon capture
This capability future proofs industrial energy systems and supports compliance with tightening carbon regulations.
Frequently Asked Questions about Energy Efficiency
How can my business improve energy efficiency?
By integrating CHP, waste heat recovery, and process optimisation to capture and reuse energy that would otherwise be wasted.
Can Clarke Energy systems provide cooling as well as heat?
Yes. Using trigeneration, recovered heat can power absorption chillers to provide process or comfort cooling.
What fuels can your systems operate on?
Natural gas, biomethane, and green hydrogen.
How does this support decarbonisation?
By reducing fossil fuel use, increasing efficiency, and enabling the switch to renewable fuels.
