Providing Waste Heat Recovery Solutions That Improve Energy Efficiency and Carbon Intensity

ElectraTherm’s heat to power and net-zero cooling to power systems convert sources of low temperature heat into clean electricity, ready immediately.

All you need is hot water.

Improve Your Bottom Line and the Environment

Our energy efficiency solutions have been in development since 2005. Countless hours of testing – and learning from both our failures and successes – have allowed us to develop an Organic Rankine Cycle (ORC) solution with the lowest-in-class heat requirements and industry-leading efficiencies.

Converting Heat Into Clean Electricity
The Future of Energy Efficiency

ElectraTherm’s simple and reliable products use an Organic Rankine Cycle (ORC) along with proprietary technologies to convert low-temperature heat into clean electricity, with no additional fuel consumption or emissions. Our waste heat recovery solutions use hot water as a thermal medium to power our closed-loop system, providing up to 150 kWe in addition to reducing the parasitic load. Our solutions align with many corporate sustainability and environmental milestones, making our solutions an ideal compliment to any company wishing to improve their bottom line and the environment.

Reduce Costs

Our solutions use an Organic Rankine Cycle (ORC) to increase efficiency by converting unused heat into clean electricity. This process also reduces the cooling load 70-100%, further offsetting energy demand. Operators benefit from lower energy costs and are typically eligible for incentives promoting energy efficiency, cogeneration, geothermal generation, along with other clean energy initiatives.

Reduce Emissions

Many power generation and industrial processes see approximately 60% of fuel energy lost as waste heat. By capturing this heat you prevent the waste of energy and generate clean electricity, which can be used to offset site energy demand. Our solutions are proven to decrease fossil fuel consumption and their related emissions, reduce or eliminate flaring, as well as reducing reliance on the grid by achieving a more circular economy.

Increase Efficiency

Capable of generating up to 150 kilowatts of clean electricity from waste heat, our systems increase efficiency up to 10% – either by reducing fuel consumption and emissions or by increasing power output. Our net-zero cooling solution, the Active Cooler, is capable of offsetting the cooling load while generating electricity. ORC heat recovery technology is the future of energy efficiency.


Waste Heat Recovery’s Role In ESG Strategy

What is ESG? Environmental, social, and governance (ESG) refers to a company’s set of standards in relation to sustainability, human and social capital, leadership, and compliance. These factors play an increasingly large role in business decisions as shareholders are becoming more concerned with how an organization’s (primarily) eco-social practices will…

The Potential of ORC Flare Elimination

The Reality of Flaring The flaring of methane is commonplace at many landfills, biogas and wastewater treatment plants (WWTP), and oil and gas well sites across the globe. Industries routinely flare to dispose of unwanted gases and to prevent pressure build up. Not only are these flares a waste of…

What is “Cooling to Power”?

As the heat load is reduced, this allows cooling to power systems to prioritize the generation of clean electricity. When the cooling load increases the system will automatically adjust power output to fulfill engine cooling requirements, maintaining engine cooling independent of the generator’s operating status.

Factors that make a successful application


The amount of heat available is the largest factor in determining if a heat source is viable for ORC heat recovery. While heat sources as low as 70°C can be used, heat sources above 100°C are considered ideal. Other variables that play a role in determining output are the ambient temperature, flow rate, and hot/cold water temperature differential.


The more time an application is operational, the more heat there is available to convert into electricity. There are 8760 hours in a year and suitable applications will experience 80% up-time.


Installing an ElectraTherm ORC comes with several benefits, one of those is increasing efficiency and reducing energy dependence on the grid. Projects located in areas with high costs of power see the fastest returns on investment.


Companies looking to leverage sustainable technology that actively supports ESG initiatives can do so with the help of our ORC systems. From recycling wasted thermal energy and reducing emissions to serving as a micro-grid component providing electricity to remote regions, ElectraTherm’s solutions provide a range of benefits.


Applicable fluid heat sources are between 70°C and 150°C.
Heat sources above 150°C – such as exhaust gases and thermal oils – can be utilized with the deployment of an additional heat exchanger.


Power Generation

Engines generate large amounts of heat and require cooling. By adding an ORC system to your engine you can easily produce clean electricity from the available heat, increasing efficiency up to 10% - with no additional fuel combustion or emissions. Maximize your efficiency by taking advantage of the exhaust gases or achieve net-zero cooling and power generation using the Active Cooler.


Methane Optimization

For industries dealing with natural gases - such as landfill gas production, biogas plants, and wastewater treatment - integrating an ORC heat recovery system can increase engine efficiency, generate renewable energy, or even eliminate flaring.


Industrial Waste Heat

Industrial processes generate loads of heat, over half of this thermal energy is lost as waste heat and ends up vented to the atmosphere or dumped into our bodies of water. With ElectraTherm this low-temperature heat from industrial processes can be used to generate clean power - improving your bottom line and the environment.


Oil and Gas

Oil and gas heat recovery applications provide operators with numerous ways to benefit from the utilization of waste heat. Those who integrate an ElectraTherm ORC system are able to generate clean electricity while achieving net-zero cooling, increase engine efficiency up to 10%, provide a baseload power supply in remote areas, exceed air quality standards through flare elimination, and even the ability to generate geothermal power.



With recent advancements in ORC technology, low-temperature sources of geothermal such as hot springs and co-produced fluids can now be used to generate profitable power - with minimal costs to the operator. Our scalable and robust ORC systems easily provide baseload power to projects that are either remote or require small footprints.


Biomass Systems

Projects incorporating biomass or biogas boilers for anaerobic digestion, drying, heating, or power generation are particularly attractive for use with our ORC systems due to reduced capital costs (i.e. the boiler), easy installation, and access to hot water.
