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.


Investigation of Hydrotreated Vegetable Oil as fuel –
HVO passes first test procedures

10th May 2016 – Hydrotreated Vegetable Oil (HVO) is partially admixed to diesel fuel nowadays. The Institute for Energy Process Technology and Chemical Engineering (IEC) of the Technische Universität Bergakademie Freiberg and the OWI Oel-Waerme-Institute GmbH investigated within a joint research project, whether HVO represents a complement to the offer of conventional and biogenic fuels in the heating market. They concluded that from a technical point of view HVO is in principle suitable as an admixture to fuels such as low-sulfur heating oil for oil heating. … More

IGCS Winter School 2016 –
The sustainable production of liquid biofuels and their application

28th April 2016 – How can biodiesel be produced in efficient manner, environmentally friendly and cost-effectively? Which chemical-physical properties are relevant for the storage and stability of biodiesel? Which aspects of the sustainability in respect to the production and utilization of biodiesel need to pay a special attention? During the IGCS Winter School at the Indian Institute of Technology Madras (IIT Madras) in Chennai (February 22 – March 4, 2016), 30 students became familiar with these and other questions. The key issues were the production, characterization and utilization of liquid biofuels, particularly in relation to biodiesel as well as the related technological challenges and political aspects. … More

Heating with pyrolysis oil –
EU-Project aims to use biomass residues in residential heating market

25th April 2016 – The objective of a recently started EU research project called “Residue2Heat” is to use various streams of biomass waste for residential heat generation. The aim is, by means of a liquid fuel produced in a sustainable manner from agricultural and forestry biomass residues to considerable reduce the CO2 emissions in the heating market compared to fossil fuels. This 2nd generation bio-fuel, is being produced employing the fast pyrolysis process using a wide variety of biomass residues as feedstock. An international consortium of research institutions and SMEs involving Oel-Waerme-Institute will examine the standardization and the use of FPBO in the heating market and optimize a condensing heating system for the use of this new kind of fuel. … More

Test of the no-harm-criteria of additives –
Studies on effectiveness and on minimum requirements

19th April 2016 – Within the scope of a research project, the Oel-Waerme-Institut examines the effectiveness of mineral oil additives and their fulfillment of minimum requirements (no-harm-criteria) in additized fuels. Additives serve quality assurance and fulfill specific functions, for instance by improving the oxidation stability of mineral oil products or by protecting metallic surfaces against corrosion. The focus is on the question to what extent the increasing diversification and aging processes of fuels during their storage affect the effectiveness of additives or even have negative effects due to unexpected interactions. … More

Thermal power stations could become more efficient and economic –
New reformate gas engine technology increases electrical efficiency by at least 10 %

15th February 2016 – Small combined heat and power (CHP) plants in the power range of 50kW electric could be driven more economically in the future. This is possible due to the reformer technology, which produces energetically higher quality fuel gas from natural gas and steam, in parallel to the combustion engine’s operation. The principle origins from the steam reforming of diesel fuel and was transferred to the reformate gas engine. The created fuel gas (reformate) consists of hydrogen, methane, carbon dioxide and carbon monoxide and is fed directly into the engine. By that, less fuel is needed and the system’s electrical overall efficiency increases significantly. The highlight of the reformate gas engine is, that no additional external power is necessary, because the required heat for the reforming process is taken from the hot engine exhaust. … More
