Industrial Waste Heat Recovery Systems
Reducing emissions-intensity for industry by developing profitable, clean energy projects with waste heat recovery systems.
Waste Heat to Power Solutions
Terrapin develops waste heat to power projects for industrial clients seeking to lower their emissions-intensity. We offer a turnkey solution that maps and evaluates their waste heat resource and converts it into useable and valuable energy.
The electricity generated from these projects can be used to:
Offset client grid electricity consumption
Replace power currently being produced on-site from diesel gen-sets or natural gas units
Sell back to the grid, generating revenue from electricity prices and future capacity market payments
Businesses that make their own power from their waste heat resources would reduce their scope 2 emissions and squeeze the most value out of their existing processes - a compelling ESG story for stakeholders.
Why Innovators Are Turning To Waste Heat Recovery
Rising emissions and ESG pressures, carbon pricing, renewable portfolio standards and a new Investor Tax Credit are transforming waste heat into the next clean energy source.
Oil and gas and heavy industry can reduce their emissions-intensity in an economic way as they transition to a net-zero future by converting their waste heat into power.
What Is Waste Heat Recovery?

No industrial equipment nor process is 100% efficient. Inefficiencies are often in the form of waste heat losses. Depending on the temperature of this waste heat, it can be reused locally for preheating purposes, or converted to an emission-free source of power.
In a waste heat to power project, a waste heat recovery system extracts the thermal energy from the exhaust gas of an industrial plant to power the Organic Rankine Cycle (ORC) module via the intermediate fluid to turn waste heat into electricity. The intermediate fluid, which is usually oil, pressurized water or steam, transfers heat to the organic fluid in the ORC evaporator, where the organic fluid vaporizes. The vaporized fluid then passes to the turbine. The vapour expands, causing the turbine to spin and creating electricity through the generator. The vaporized organic fluid then continues through the cycle to the condenser where it returns to a liquid state. It then passes through the pump before beginning the cycle again.

In Western Canada, we have exclusive rights to develop projects using Exergy International’s Organic Rankine Cycle technology – a cutting-edge innovation in the waste heat to power space that uses a radial outflow turbine to effectively capture and convert waste heat into emission-free, baseload electricity.

Terrapin's Partnership Development Model
Before proceeding with a waste heat to power project, Terrapin evaluates the quality of the waste heat resource by temperature, flow rate and operational uptime. Terrapin also assesses the site location and access to the waste heat resource to ensure the safe integration of the project with the client's existing assets.
Beyond the heat source and site, Terrapin considers the jurisdiction's power market, carbon offset market, policies, and regulations to evaluate the potential economic value of the project. If it does not generate economic value for the client, Terrapin does not pursue it.
Upon checking all the boxes, Terrapin launches the pilot project development and explores opportunities for duplication across client's portfolio of assets to maximize the waste heat recovery for the client. Through Terrapin's Partnership Development Model, the entire project line is financed by third-party capital.
By integrating this waste heat to power project with the compressor station, the client harnesses residual heat from the natural gas turbine to be used as an energy source. Heat that would have otherwise been vented into the atmosphere is utilized on-site to generate emission-free, baseload electricity for the client, reducing their environmental footprint.
