Orcan Energy

We upcycle heat to clean electricity.

Our simple and flexible products convert unused energy from engines and industrial facilities into clean electricity that you can use right away. Without any extra investment or extra work. Now.

Save costs

As resources become ever scarcer, energy is becoming an increasingly valuable commodity. Harness your unused energy now and convert it into clean electricity. You will also benefit from lower energy costs and can make a valuable contribution to protecting the environment.

Reduce CO2 emissions

We have a duty to our children and grandchildren to protect our planet and find alternative ways to cover our immense energy needs. But instead, we are still wasting our resources. In industry, for example, up to 50 percent of input energy is lost as waste heat. Orcan Energy provides simple and flexible second-generation ORC solutions that turn this waste heat into valuable electricity.

Increase efficiency

We improve what is already there. Our simple products recycle energy that previously went to waste, without affecting the combustion engine. From industry and shipping to construction and transport, Orcan Energy offers the perfect combination of economy and ecology.

Munich, 19.08.2020 – Orcan Energy, leading manufacturer of solutions for the use of waste heat, is now expanding its area of application and, together with its cooperation partner E.ON, is installing six efficiency PACKs for the first time at a geothermal energy plant of FG Geothermie GmbH in Kirchweidach in Bavaria.


Our second-generation ORC solutions take waste heat from various processes and applications and turn it into clean electricity. They are used above all in the industrial, marine and power generation sectors where they can make the greatest contribution to a better world.


Our products significantly increase energy efficiency in industrial processes. They help slash carbon dioxide emissions and reduce electricity costs to an astonishingly low level. Find out more.


Our efficiency PACKs reduce fuel consumption on ships by six to nine percent and ensure a significantly better Energy Efficiency Design Index (EEDI). Harmful emissions of carbon dioxide, nitrogen oxide, sulfur oxide and soot particles are substantially reduced.


Our efficiency PACKs use hot engine exhaust gases and cooling water to generate a significant amount of extra electricity. They require little maintenance and work fully independently. Fuel consumption is also considerably reduced.


Efficient, flexible and cost effective – with over 250 units sold and over 2 Mio. operating hours, our products contain know how from 10 years of continuous development and refinement. Our patented efficiency PACKs let you generate zero-carbon electricity from heat – from engines, industrial- or cooling processes. On-site and at incredibly low electricity costs. Installation is simple – plug and play. Standardized and proven industrial components, and intelligent control algorithms ensure highly reliable, low-maintenance operation and optimal electricity generation. Wherever you are in the world.
