Summary
Biomethane is a gas consisting mainly of methane (CH4) that can be produced from agricultural and food waste or other organic materials at a low or even negative price. Since biomethane is almost equivalent to natural gas, it is seen as a possible functional substitute: biomethane can be used an energy carrier for excess renewable electricity and as a feedstock for chemical synthesis. It is possible to produce biomethane by means of various biochemical and bioelectrochemical reactors in which the main role is played by methanogenic micro-organisms that convert CO2 or other organic compounds into CH4. This project is dedicated to the development of two bio(electro)chemical reactors based on a trickle-bed reactor using raw biogas from an industrial anaerobic digester and hydrogen from an alkaline electrolysis for the synthesis of CH4. The main fundamental novelty of this project is the use of immobilized redox mediators (anthraquinone derivatives), which promote the rate of methanogenesis and thus increase the performance of the whole set-up. In the case of the bioreactor, carbon particles with immobilized redox mediators are used as the biofilm support material. In the case of the bioelectrochemical reactor, the same materials also act as colloidal electrodes. This approach is expected to significantly improve key characteristics such as methane conversion rate and power density, which will enhance the economic attractiveness of the technology. Also, the project will use zero-gap flow electrochemical cells for the first time to accelerate the screening of promising materials.
