(Deutsch) Willkommen beim Oel-Waerme-Institut

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.


Electric mobility –
Further development of fuels for operation in Plugin Hybrid Electric Vehicles

13th April 2017 – Electric cars are the cars of the future. The share of vehicles which have an internal combustion engine, an electric motor and an external charging possibility for a battery (Plugin Hybrid Electric Vehicles, PHEV) increases. This affects the user’s fueling intervals due to the hybrid propulsion, which lowers the actual fuel consumption and leads to longer storage of the fuel in the tank compared to conventional engines. This results in a forced fuel degradation. By increasing levels of synthetic fuels and biofuels in the fuel the composition can vary even within existing norms. Hence, new questions arise regarding the fuel’s operability due to longer residence times in the fuel supply system which can be more than 6 months. … More

Successful commissioning –
Fuel cell system for ships produces electricity

2nd February 2017 – In the research project „Ship integrated fuel cell“ (SchIBZ) the developed power system on the basis of diesel fuel and SOFC fuel cells has started electricity production at the end of 2016. After the successful commissioning the system reached a power output of almost 30 kW with a maximum gross efficiency of 56 %. In comparison to the classical diesel generators which reach efficiencies up to 40 % the fuel cell power system is not only energy-efficient, but also clearly quieter and less pollutant. The reduction of harmful emissions is necessary in harbour areas as well as on coastal and river passages due to the increasing national and international legislations. … More

Fuels in automotive applications –
Technical solutions for fuels and fuel-handling components

3rd January 2017 – Technical developments of automotive applications are continuously encountered with new challenges. The most frequent objectives are to increase efficiency, reduce emissions of CO2 and other harmful substances and to extend the lifetime of components. OWI, the Oel-Waerme-Institut gGmbH, a non-profit affiliated institute of RWTH Aachen, and its parent company TEC4FUELS GmbH, support companies in their activities of research and development and testing. Working in the areas of fuels and technical components for fuel conveying parts, they offer intelligent technical solutions that help you to save time and money. … More

Fuels and lubricants in the focus –
OWI´s activity report 2014 / 2015 is published

28th October 2016 – The new activity report of the OWI Oel-Waerme-Institute provides an insight into its research and development activities. OWI is an affiliated institute to RWTH Aachen that deals with the energy efficient and reliable use of conventional and renewable energy carriers. The core subject of the current report is „fuels and lubricants“. A guest article of Prof. Dr. Christian Küchen, the managing director of the Association of the German Petroleum Industry, describes the state of tension between political goals in the field of climate protection and the great importance of petroleum products for the economy. Furthermore, possible future development pathways are shown. … More

Diesel and water are used to generate „clean“ power –
Milestone in the fuel cell-project „SchIBZ“

21st October 2016 – The OWI reformer technology enables the transformation of diesel fuel and water to a fuel gas with high hydrogen content. Such reformers can be integrated into fuel cell systems which generate electricity. In an ongoing research project a reformer of the OWI shall transform diesel and water into hydrogen for the operation of a fuel cell system. The hence generated electricity can be used in the future for the energy supply aboard of seagoing ships in a highly efficient and environmentally friendly way. … More
