The HiGradeGas project

The consortium behind the project HiGradeGas consists of five research institutions – Technical University of Denmark (DTU), University of Southern Denmark, Stockholm University, Luleå University of Technology and Sintef – together with four companies from Denmark, Sweden and Switzerland –  Danish Power Systems, Rambøll Danmark, NeoZeo og EngiCer. The project is managed by senior researcher Andreas Kaiser from DTU Energy. Read the press release (in Danish) from Innovation Fund Denmark here.
By upgrading biogas from manure and other sources it can be used in the form of methane as fuel for heavy vehicles. Novel nanostructured materials will make this upgrade economically viable, even in small facilities. Now, Innovation Fund Denmark invests in an ambitious project, led by DTU Energy, which will demonstrate the concept in practice.

The project HiGradeGas will develop new methods to upgrade and store biogas in the form of methane. The key concept is to use nanostructured materials which absorb methane, to realise commercially competitive units on a smaller scale than today. In this way biogas from agriculture may enter the transport sector to a much higher degree than is presently the case.

Biogas is a sustainable energy source which will play a decisive role in the transition to a society independent of fossil fuels. This is in particular the case for Denmark and other countries with a large agricultural sector. One of the reasons that the market for biogas has not yet taken off, is that it is difficult to clean the biogas of CO2 and other impurities, and to store the gas for later use either for transport or in the gas grid.

This is the challenge which the HiGradeGas consortium led by senior researcher Andreas Kaiser from DTU Energy has set out to solve. They will develop novel nanomaterials, both for the removal of CO2 from the biogas and for the absorption of methane from the gas. However, good materials are not enough. An important task in the project is to develop processes to control the structure and the shaping of the materials to ensure the optimum performance. Here, both advanced electro-spinning methods and more traditional ceramic processes will be pursued. The project will end in the design, construction and test of a unit demonstrating the promise of the concept in practice. Finally, a life-cycle assessment of the technology and its integration in the overall energy system will be performed.
