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.


Research radar Germany 2017 –
Exemplary projects to production of greenhouse gas-diminished fuels

12th December 2017 – Liquid fuels and heating oil’s make an essential contribution to an assured and economic energy supply in the sectors of mobility and domestic heating. In future, their contribution to the climate protection should clearly increase. Hence, the research has been intensely working on the production of reduced greenhouse gas reduced liquid fuels in order to use their resources in future also. … More

Energy transition only with liquid carbon neutral fuels –
OWI and TEC4FUELS support technically mature developments

6th December 2017 – Possible ways to successful implementation of the energy system transition, for the purposes of CO2 reduction of 80% to 95%, are an objective of the topical political discussion. The discussion was complemented with two current studies of the German Energy Agency (dena) and the Prognos AG with new facts. The first intermediate result from the dena pilot study “integrated energy transition” deliver important arguments for a technology-open design of the energy transition. Therefore, a future wide technology mix would be clearly favorable and more robust, than scenarios which intend a high degree in electrification. Explicitly, the studies highlight all examined scenarios that the achievement of the climate protection goals is possible only with the help of synthetic fuels produced on basis of renewable raw material. Hence, Germany should support the market launch of the suitable technologies. … Weiterlesen

Vegetable oil as a fuel in the agriculture –
Retrofitting of tractors for multi fuel application

11th October 2017 – In the agriculture the widening of the application of vegetable oil as a fuel in tractors could contribute to more sustainability and climate protection in the framework of a resource-friendly bio-economy. However, the compatibility of fuel-leading components with vegetable oil fuel must be checked, so that the operational safety and lifetime duration of tractors and other agricultural machinery can be guaranteed. In order to utilise vegetable oil from rape as a part of a Multi-Fuel application strategy, a research project investigates in particular the interaction between fuels and diesel injectors. … More

OWI – Successful with a new structure and future fuels

28th August 2017 – The OWI Oel Waerme Institute latest review on its new adjustment was very positive. With incoming orders of more than two million euros in 2017 for public funded research projects for the development and use of liquid energy sources the non-profit research institute sees itself very well positioned. For 2018 incoming orders in similar order are expected. „The new adjustment bears the fruit we expected “, says OWI managing director David Diarra. „The current discussion about climate and environmentally friendly mobility leads to a demand for OWI´s competences in the area of sustainable liquid fuels“, explains Diarra. … More

Biooils from waste materials –
Innovative liquid fuels for the domestic heating market?

31st May 2017 – Within the turnaround of energy policy liquid regenerative energy sources would have to be put on a broader raw material base, to make increasing contribution to climate protection. Up to now the use of waste materials (used cooking oil, pyrolysis oil, tall oil, etc.) for the production of synthetic fuels by means of hydrogenation is an option that is little studied. The hydrogenation of vegetable oils is an increasingly significant process for the production of high-quality fuel components and fuel components from renewable raw materials. Their properties are very similar to those of diesel and fuel oil. The aim of research and development activities is to produce a fuel (hydrogenated bio oil, HBO) at the technical level of fuel oil which then could be added to the fuel oil and be used as a supplement in the domestic heating market.  … More

Optimizing a biogas gas engine for thermal power stations –
Power yield is to rise

11th May 2017 – Combined heat and power (CHP) plants convert regenerative generated biogas into power and heat, which can be fed into power or district heating grids. Due to technical reasons the production of heat is higher than power. A new research project aims to increase the share of generated power at the expense of heat. Thus electric efficiency of CHP units with biogas engines rises. The concept intends to integrate a reforming unit into the CHP plant. … More
