Abstract:
As methanol is taking the lead in the path towards a sustainable energy market, providing its building blocks in a renewable way becomes fundamental to allow a completely green product. Methanol can be obtained starting from hydrogen (H2) and carbon monoxide (CO). Implementing solid oxide electrolysis (SOE) cells, H2 as well as CO can be formed from water (H2O) and carbon dioxide (CO2) during co-electrolysis. Moreover, thanks to the nickel catalyst present in the cells, it is also possible to perform internal reforming of methane, producing additional hydrogen. This set of characteristics can play a significant role in obtaining syngas directly from biogas, a renewable source which mainly consists of methane and carbon dioxide.
A mathematical model is developed to simulate the temperature profile across the SOE cells, comprehending both the reforming mechanism of methane and the electrochemical reactions of steam and carbon dioxide. The model can also be operated in AC:DC operation, a Dynelectro ApS’s patented technology. This tool can provide a strategy to heat up the cells when working at an endothermic operating point, in order to have more flexibility to reach thermal equilibrium. After the initial theoretical work done via the modelling, at Dynelectro’s laboratory experiments are being carried out to verify and prove these ideas, as well as to validate the mathematical model. A solution to explore is represented also by considering other solid oxide cells compositions (e.g., nickel-free cells, GDC cells).
The research will then switch from the cell level to the system level. In fact, a system model will be built to address the performance of the electrolyser when coupled to the auxiliary equipment necessary to operate the plant in its totality. This model will be first based on the current design of the Dynamic Electrolyser Unit (DEU) under construction at Dynelectro. Then it will be upgraded to include biogas conversion and methanol production. This will give the basis for a later design and construction of a new DEU site.
Finally, the results of the models and the experiments could be examined to perform a techno-economic analysis. This would help to evaluate the benefits that this solution may have compared to state-of-the-art plant designs.
