Climeon is a public company, listed on the Stockholm Nasdaq Stock Exchange. The company is located in Stockholm, Sweden and has 90+ employees. Climeon has customers and partners all over the world and in various industries.

Climeon was founded by Thomas Öström and Joachim Karthäuser in 2011.


Climeon is a clean-tech vendor, providing a technology that uses the energy in waste heat from industries and low-temperature geothermal heat to generate electricity. The company received its first order in 2015 and has since then established a customer base consisting of Viking Line, Virgin Voyages/Fincantieri, Varmaorka and SSAB, among others. The product is protected by patents and offers a market-leading performance within its areas of application.

Waste heat and geothermal energy (below 120°C) jointly comprise a vast energy source that is largely untapped today due to limitations of existing technologies. Climeon's product is the first waste heat recovery system which is able to utilise this previously unexploited source of energy to efficiently produce electricity. Climeon is currently focusing on four segments: maritime, steel, gensets (generators) and geothermal energy.

Doing good for the environment has been a central part of Climeon since the company was founded, and achieving the objective by enabling profitable business for the customer has served as a guiding principle throughout the development of Climeon's Heat Power system. The environmental benefits consists of:

Significant energy savings

A Climeon Heat Power module (150kW) can generate enough clean electricity per year to provide up to 263 typical Swedish detached houses with household electricity. With 100 000 modules installed, the emissions of up to 98 million tonnes CO2 would be avoided annually. A forest the size of Denmark would be required in order to absorb the same amount of CO2 annually.

Minor environmental impact in the manufacturing process:

All renewable energy technology impacts the environment negatively during manufacturing. For example, large amounts of steel and energy are used to manufacture a wind farm. The power plant needs to be in operation a certain amount of time to compensate for the negative impact the manufacturing has had on the environment - what is known as the environmental payback time. For renewable energy technologies such as wind and solar power, the environmental payback time is around six and 18 months, respectively. The production of Climeon Heat Power system requires approximately 40 000 kWh (kilowatt hours) of energy. Hence the module needs up to 15 days to compensate for the amount of energy used in production, resulting in an environmental payback time of less than two weeks.


Climeon has received several awards for the positive impact the Heat Power system has on the environment. The World Wildlife Fund named Climeon a Climate Solver in 2016. The World Wildlife Fund stated that if Climeon could convert ten percent of all waste heat from industries and merchant ships into clean electricity 2026, the world's annual CO2 emissions could be reduced by 21.6 million tonnes. This equals an installed base of approximately 25 000 Climeon Heat Power modules globally. The industry experts Frost & Sullivan deem the system to be the best in the world in its category, and expects the Climeon Heat Power system to take off in the maritime industry. The system also received the E-prize 2016 in the renewable energy category. E-prize is hosted by E.ON and Veckans Affärer, and is the largest energy competition in Sweden. The Swedish Energy Agency also called the system "The greatest energy innovation in 100 years". 


Asset 3-8

In the illustration above, the physical footprint of a 17 MW windfarm and 13.5 MW solar power park is compared to a 5.4 MW installation, where all three respectively output 46 400 MWh electricity per year.
The illustration demonstrates that the physical area needed per MWh is considerably lower for the Heat Power system than for a solar or wind park.
