Improve Your Bottom Line and the Environment

Our energy efficiency solutions have been in development since 2005. Countless hours of testing, successful demonstrations, happy customers, as well as learning from our successes – and shortcomings – have allowed us to develop an Organic Rankine Cycle (ORC) solution with the lowest-in-class heat requirements (as low as 70°C) and industry-leading efficiencies (up to 10%).

Converting Heat Into Clean Electricity
The Future of Energy Efficiency

We use an Organic Rankine Cycle (ORC) along with proprietary technologies to convert waste heat and geothermal heat into clean electricity – with no additional fuel consumption or emissions. Our low temperature waste heat recovery solutions use hot water as a thermal medium to power a closed-loop system, providing up to 150 kWe in addition to reducing the parasitic load.

Reduce Costs

Our solutions increase efficiency by converting unused heat into clean electricity while simultaneously reducing or eliminating the cooling load, further offsetting energy demand.

Operators benefit from lower energy costs and are typically eligible for incentives promoting energy efficiency, cogeneration, geothermal generation, and 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, generate clean electricity, and mitigate emissions. A win-win-win.

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 providing a dependable electrical supply.

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 newly available net-zero cooling solution is capable of offsetting cooling loads while generating electricity. Low temperature waste heat recovery 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


Our systems utilize heat sources above 70°C to convert thermal energy into clean electricity. Higher temperatures correlate to higher power output thereby achieving a quick return on investment. Other variables that play a role in determining power output are the ambient temperature, flow rate, and hot/cold water temperature differential.


Some units run all the time, and some are only used intermittently. There are 8760 hours in a year, the more of these an application is operational the faster the return on investment.


The electricity generated by ElectraTherm’s ORC systems can be sold to the grid or used to offset power demand – serving as a revenue stream for many years to come. The higher the value of power, the faster the return 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 at remote sites, ElectraTherm’s solutions provide a range of benefits.


Applicable fluid heat sources are between 70°C – 150°C (158°F – 302°F).
Heat sources above 150°C (302°F) – 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 use the available heat to generate clean electricity while simultaneously reducing the cooling load up to 100%. This results in an increase of efficiency up to 10% - with no additional fuel consumption or emissions.


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 tremendous amounts of heat, most of which goes unused and vented to the atmosphere or dumped into our bodies of water. With ElectraTherm, this low temperature waste heat can be used to generate clean electricity - improving your bottom line and the environment.


Oil and Gas

ORC oil and gas applications provide operators with numerous ways to benefit from the utilization of waste heat such as: the generation of clean electricity while achieving net-zero cooling, increasing engine efficiency up to 10%, providing baseload power in remote areas, exceeding 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 power. This opens the door for new geothermal heat recovery projects across the globe. 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) along with easy installation and access to hot water.
