Germany-based, Orcan Energy "harvests waste heat from small to medium sources & turns it into energy". To do so, the startup sells plug & play efficiency "PACK"(s), that can easily be integrated on existing flue gas, steam & thermal oil circuits as well as liquid heat (i.e. hot water) sources; these include furnaces in cement, zinc, metal & glass industry, as well as thermal afterburners in automotive, construction & wood processing and refineries. The startup's innovation is an "Organic Ranking Cycle" (ORC) inside the PACKs, which works as follows: an “evaporator” transfers the heat source into the PACK; that heat pressurizes a working fluid, which is then routed/ vaporized to drive an expansion machine/ generator...
