I’m interested in modeling an energy system that connects biogas plants, electrolysers and methanation plants. I’m thinking of the following components:
- Electrolyser: input: electricity from wind/pv or grid; output: H2, heat
- Biogas Plant: input: heat ; output: CO2, CH4
- Methanation Plant: input: H2, CO2, electricity; output: CH4, heat
At first, it’s sufficient to calculate the hourly and yearly production of CH4 (synthetic CH4 from methanation + CH4 from biogas) with the option of either just using pv and wind for the electrolysis and methanation or a mix of pv, wind and grid electricity. Second priority would be modeling the use of the waste heat supplied by the electrolysis and the methanation for the biogas plant. Generation costs would be great too, but at first I would keep it simple an calculate the costs in already existing excel tools, using the CH4 production and electricity consumption provided by the modeled energy system.
Is anyone working on something similar? As far as I know, electrolysis is already implemented as a transformer in oemof but so far, biogas plants and methanation transformers are not, right?
