According to the latest assessment report from the Intergovernmental Panel on Climate Change, a considerable reduction in CO2 emissions is required to limit the consequences of climate change. Producing fuel from renewable sources such as waste wood and straw or renewable electricity would be one way to reduce carbon emissions from the area of transportation. This is an area which is being addressed by researchers at the Technical University of Munich (TUM).
Ethanol is usually produced through the fermentation of sugars from starchy raw materials such as corn, or from lignocellulosic biomass, such as wood or straw. It is an established fuel that decarbonizes the transportation sector and can be a building block to reduce emissions of CO2 over the long term. In collaboration with the Lappeenranta-Lahti University of Technology (LUT) in Finland, researchers at the Straubing Campus for Biotechnology and Sustainability of the Technical University of Munich (TUM) have developed a new process for the production of ethanol.
In this context, offcut materials from the area of forestry are used together with hydrogen. The hydrogen is produced by separating water into hydrogen and oxygen with the use of electricity – in other words, with the use of water electrolysis. In the future, this will allow the excess electricity to be used for the production of ethanol.
“The overall process mainly consists of technically mature sub-processes. However, the composition of the process steps and the final step – the hydrogenation of acetic acid to produce ethanol – are new,” explains Daniel Klüh, a doctoral student at the Professorship of Renewable Energy Systems at the TUM Straubing campus.
