Small-scale biogas upgrading : feasibility study of small-scale biogas upgrading in Iceland and possible methods
Methods for upgrading biogas to vehicular standards, to reduce the need for petrol and diesel, are examined if feasible for small-scale upgrading. Water Scrubber adsorption and Membrane biogas separation where found feasible. The water scrubber system was found the only available option for …

Gas diffusion transport characteristics and mathematical description of membrane systems with application for biogas upgrading.
… that could remedy the situation - channelling biogas for use as a renewable energy source using membrane technology. The study began with observing the behaviour of biogas components as they travel selectively through the membrane support. This was done by conducting gas permeation tests to …

Technical and economical evaluation of Power-to-Methane technologies, based on green H2 and biogenic CO2
… (BHM), employing the CO2 resulting from the biogas upgrading in anaerobic digestion plants. Two different solutions have been analysed: a BHM process with the injection of CO2 and H2, and a BHM process with the injection of Biogas and H2. Evaluation of the optimal location for the …
