Conversion of power generation plants to biomethane

The conversion of power plants to biomethane production, like any expansion or upgrading project, requires a complex study that is not limited to the selection and costing (capital + operating costs) of the upgrading unit, but includes the following integral parts:

1. The interconnection of the new upgrade unit with the existing anaerobic digestion unit which also includes the internal management of self-consumed energy.
2. The study of the optimal solution for providing self-consumed energy (electric + thermal), which is the most important factor in shaping the cost of the final product. In addition, the origin of self-consumed energy has a significant contribution to the plant’s carbon footprint, which in turn affects the revenue from the sale of emission rights.
3. The study of ensuring, at the lowest possible cost, the thermal energy required for the proper operation of the digesters, pasteurization, desulphurization and other thermal loads that, in the case of electricity production, weighed on the thermal energy co-produced in the CHP.
4. The optimal solution for driving the final energy product towards disposal – consumption so as to ensure not only the minimum cost of injection / transportation, but also to facilitate the adaptation to the current demand (long-term or seasonal) and the possibility of choosing alternative commercial solutions, depending with the future development of the market.

The company Agromethane GREECE can undertake and perform the entire range of activities required for the conversion of a biogas-to-electricity unit into a pure biomethane or hybrid unit. These activities at the study level ensure the minimization of costs, the design of the relevant systems, preliminary site studies and, of course, the documentation of technical and economic feasibility.For the licensing of the project, it can undertake the review of the environmental impact studies or the re-drafting of the environmental impact study, construction and production permits, where they are required. For the execution of the project, it undertakes the implementation studies of the new projects, the provision of coordination and supervision services of suppliers and construction contractors of the facility as well as the commissioning during the initial period.
