Welcome to the Oel-Waerme-Institut

OWI provides research services investigating and developing concepts and new technologies for heat and power generation on a basis of fossil and renewable fuels. It aims at developing energy-efficient and environmentally friendly products which are marketable. At the same time, OWI cooperates closely with industrial partners and research institutes and sees itself as an mediator between fundamental and applied research. OWI is a non-profit organisation and an acknowledged institute affiliated to RWTH Aachen University.


Fuel cells produced in series -

Business network BiS-Net founded

24th September 2014 – Mass production of fuel cells in Germany is the goal of the newly founded cooperation network BiS-Net. In this network, which also includes the OWI Oel-Waerme-Institut as a research partner, ten small and medium-sized companies and research facilities work on the realization of portable and stationary applications for marketable and mass production suitable fuel cells. The market introduction of technical realizable systems is mostly hindered by high costs due to the applied materials and production engineering. … More

Intelligent energy supply with fuel cells -

Annual report 2013 of OWI published

17th June 2014 – “Reforming and fuel cell systems” is the main topic of the published annual report 2013 of OWI Oil-Heat-Institute. The affiliated institute of RWTH Aachen describes for one of its central research and development areas the technical potentials and application possibilities of portable, mobile and stationary fuel cell systems for power and heat generation. Fuel cell systems can be operated independently from the energy network by means of reforming liquid energy carriers, such as petrol, diesel or (bio-) methanol into hydrogen. … More

Could HVO complement fuels in the domestic heating market? –

Need for research for market launch

21st March 2013 – Due to its chemical-physical characteristics, hydrogenated vegetable oil (HVO) offers the potential to complement fossil and biogenic fuels in the domestic heating market. From a political point of view, HVO is interesting in respect of climate protection, because it could decrease greenhouse gas emissions. The large scale Production in stand-alone plants as well as the joint hydration of vegetable oil and the heating oil – diesel – fraction in conventional refinery processes (coprocessing) is technically possible and economically interesting. HVO produced in stand-alone plants is already available on the market. However, know-how about both production processes of vegetable oil and the application-specific characteristics of the resulting biogenic fuel must be expanded. … More

Doctoral candidates exchanged ideas -

Common colloquium of OWI and IEC

04th March 2014 – Mid February, the first corporately scientifically colloquium by the OWI “Oel Waerme Institut“ and the institute for energy process engineering and chemical engineering (IEC) at the TU mining academy Freiberg, took place in Herzogenrath. Doctoral candidates in the field of combustion engineering and fuel cell systems of the two institutes presented their works and discussed them with their colleagues. More

Joint research for rational use of energy -

Oel-Waerme-Institut and the University of Hamm-Lippstadt cooperate

9th December 2013 – The University of Hamm-Lippstadt (HSHL) and the Oel-Waerme-Institut (OWI), affiliated institute to RWTH Aachen University, agreed to deepen and to extend their research- and development projects on the basis of a formal cooperation. The complementary skills of HSHL and OWI are supposed to be combined and used in order to carry out joint R&D-projects. Both institutions see great potentials for rational use of energy in the field of heating, ventilation and air-conditioning technology with regard to building services and automotive. … Weiterlesen
