“…To meet the biomethane potential identified in this study, currently unused feedstock potential needs to be enabled for biogas production. The bulk of the resource potential is located near farms, which often lack sufficient funding, the required know-how, and bargaining power to engage in economically feasible biogas production [73]. According to Lyng et al [74], sizeable incentives are usually needed to make agricultural biomasses available for biogas production.…”

“…On regional and local levels, new business models are needed between energy producers and farms enabling better utilization of both biogas and digestate [75,76]. Careful planning of the whole supply chain has proven to be a key aspect for successful biogas systems in Danish conditions [73] but lags behind in Finland due to poor cross-sectoral co-operation between relevant actors [39]. However, encouraging examples such as that of the Biohauki company [77], suggest that local biomethane production from waste materials can indeed be feasible in Finland with proper planning and willing actors.…”

Electrification is a frequently discussed solution for reducing transport related carbon dioxide emissions. However, transport sectors such as aviation and heavy-duty vehicles remain dependent on on-board fuels. Here, biomethane is still a little exploited solution, and the case of heavy-duty vehicles is particularly underappreciated despite the recent technical advances and potentially notable emission reductions. This paper discusses the potential of biomethane in heavy-duty road transport in the case of Finland, where the utilization rate is low compared to the technical potential. To this end, the potential of biomethane production through both anaerobic digestion and gasification was calculated in three scenarios for the heavy-duty transport fleet, based on the literature values of biomethane potential and truck class fuel consumption. The authors find that approximately half of the heavy-duty transport in Finland could be biomethane fueled by 2030. The estimated production costs for biomethane (81-190 €/MWh) would be competitive with the current consumer diesel price (152 €/MWh). Utilizing the total biomethane potential in heavy-duty transport would furthermore decrease the respective carbon dioxide emissions by 50%. To accelerate the transition in the heavy-duty transport sector, a more comprehensive political framework is needed, taking into account both production and consumption.

“…Uhlemair et al [18] developed a mathematical model which is used for optimizing the economic component of bioenergy production (biogas) within a specific system (village, town, city, etc.). A similar model was developed by Jensen et al [19], which additionally included energy balances and technical aspects of bioenergy production. Some models consider only the environmental life cycle assessment of the plant [20].…”

Agriculture is one of the leading sectors on the global level contributing to greenhouse gas (GHG) emissions increase. With the utilization of biogas production technology within the agriculture sector, ecological benefits could be achieved, with immediate economic profit. Therefore, to retain economic profit and environmental sustainability, implementation of bioeconomy principles is of key importance. This paper examines four options of digestate treatment, which is identified as one of the highest operational cost for the biogas plant. A simple and robust model in Excel Solver was developed to determine the best solution for minimising GHG emissions and maximise profit for the biogas plant operator, through an upgrade of the plant with digestate treatment technologies. The model was implemented on a case of a Croatian biogas plant and the best solution in terms of GHG reduction and profit increase proved to be fertilizer production (Option 1), through a crystallization process of struvite within the digestate. This option obtains a significant reduction in GHG emissions compared to standard biogas production without additional upgrades (Option 4), by over 90%, and increase of profit for the biogas plant operator, which diversifies the income source and creates multiple positive impacts on the environment.

“…Therefore, the private economic competitiveness of biomethane can already be determined at the gate into the gas system: if the fuel costs including CO 2 -costs are sufficiently low, biomethane could compete with natural gas, which may favour upgrading [26,27].…”

“…In the case of for example straw, the closest substitute is wood chips. Biogas costs are estimated on the basis of production costs found by using a profit optimising plant model with an input combination of manure and straw [27]. The straw price is the same as used in the energy systems analysis.…”

The Danish government has set a target of being fossil fuel independent by 2050 implying that a high degree of inflexible renewable energy will be included in the energy system; biogas can add flexibility and potentially has a negative CO 2 -emission. In this paper, we investigate the socioeconomic system costs of reaching a Danish biogas target of 3.8 PJ in the energy system, and how CO 2 -costs affect the system costs and biogas usage.We perform our analysis using the energy systems model, Balmorel, and expand the model with a common target for raw biogas and upgraded biogas (biomethane). Raw biogas can be used directly in heat and power production, while biomethane has the same properties as natural gas.Balmorel is altered such that natural gas and biomethane can be used in the same technologies.Several CO 2 -cost estimates are investigated; hereunder a high estimate for the expected CO 2 -externality costs. We find that system costs increase with CO 2 -costs in most cases, while the biogas target becomes socio-economically cheaper. In the case of a very high CO 2 -cost, system costs decrease and biomethane becomes the primary fuel. Furthermore, biomethane functions as regulating power and the Danish fuel consumption increases due to a higher electricity export.
