New method converts hot water into electricity
Climeon AB has developed a novel method for the extraction of electrical energy from waste heat. The company is granted a conditional loan of 14,081,000 kronor from the Swedish Energy Agency for the implementation of pilot installations.
Climeons technique based on a new type of "chemical engine" that converts hot water into electricity in a low-pressure process. The method has a significantly better efficiency than the other existing commercial practices.
- The loan will be used to develop the innovation into a product for commercial use through the implementation of pilot installations with customers in three application areas, says Boris Gyllhamn, Business Developer at Energy Agency.
The technology has the potential to cost-effectively produce electricity from waste heat, geothermal heat and solar energy. The company expected to gain market share in the areas of industrial and marine waste heat and geothermal heat, which could contribute to an annual increase of electricity supply by up to 23 TWh in a global perspective.
Climeon AB is led by CEO Thomas Ostrom, formerly at SAAB Aerospace, Vice President Product Development at Micronic Laser Systems AB. Technical Director Joachim Karthäuser, has previously worked at Royal Dutch / Shell, NKT and AGA / Linde Gas. Executive Chairman Sven Lofquist is co-founder of Micronic Laser Systems AB and member of the IVA.
If the technologyThe technology is designed from the ground up to the economic way of producing electricity from heat at low temperatures and small temperature differences. The method creates a closed thermodynamic cycle with the help of a carrier fluid release and bind carbon dioxide. This creates a gas expansion in the process that is used to drive a turbine that generates electricity. It is precisely the special absorber - that the chemical composition of the carrier fluid - which is the basis for Climeons technology. Features and speeds the process is controlled by carrier fluid composition.
One can thus produce viable electric power from the heat down to 80 ° C. A major advantage is that the whole process is working under a low pressure, and used working medium including carbon enables a secure, flexible and cost effective system.
The process was developed in close collaboration with KTH, Stockholm University, Chalmers Industrial Technology and Lund University with support from the Swedish Energy Agency.
