“…In addition, it was shown in the work that already as a result of significant losses, primarily from nitrogen compounds, the composition of the digestate may be richer in these nutrients [136][137][138].…”

The use of methane fermentation in mesophilic conditions for the energy use of cow manure and additional co-substrates from the farm can bring a small dairy farm (140 dairy cows) financial benefits of up to EUR 114,159 per year. Taking into account the need to pay for emissions calculated as carbon dioxide equivalent, this profit could be reduced to EUR 81,323 per year. With the traditional direct use of manure, this profit would drop by as much as 60% to the level of EUR 33,944 per year. Therefore, the introduction of fees for emissions may significantly burden current dairy farms. As has already been shown, just compacting and covering the manure (which costs approx. EUR 2000 per year for 140 cows) would give almost twice as much profit—EUR 64,509 per year. Although an investment in a small biogas plant with a cogeneration unit on a family dairy farm may have a payback period of less than 6.5 years and a return of capital employed of 16%, most small farms in the world will not be able to afford its construction without external subsidies. At the same time, it would make it possible to reduce emissions by almost 270 times—from 41,460 to 154 tons of CO2eq per year—and the possibility of preserving valuable nutrients and minerals and supporting soil properties in the digestate. Therefore, it seems necessary for Europe to introduce a support system for small- and medium-sized farms with this type of investment in the near future in a much larger form than it has been so far.

“…However, generally speaking, mono-digestion has lower yields than co-digestion (see 4.1.2. for more details). Financially, the profitability of these plants is modest, with revenues predominantly covering operational expenses and profit margins resting around 10 to 20% 16 (Cucchiella et al, 2018;Czekała et al, 2023). While these plants showcase the potential of a circular economy through localised operations, their restricted nature can hinder growth and optimization opportunities.…”

This work provides an ecosystem analysis of the past, present, and future of the biogas industry, from its environmental implications, to market dynamics, and future market expansion prospects. It is structured in four main sections: context, historical roots, market transitions, and future growth.Context presents climate implications of waste-related emissions, introduces biogas as a potent solution, and dives into the present-day favourable market ecosystem for this industry.Historical Roots highlights early drivers and policy instruments that favoured the industry’s nascence, however, also shaped its development in a way that later hindered growth. Market Transitions dives into the industrialization of biogas, detailing key factors that stimulated a transition to market-based approaches. Previously unidentified barriers for non-fossil-fuel industry players are presented. It then outlines recent global events’ favourable influence on stimulating increased attention to this sector.Future Growth delves into the expanded valorization routes for the inputs and outputs of biogas, alongside the mandates that will stimulate exponential demand for this sector’s future. In this, we conclude with how biogas can provide a cost competitive pathway to hydrogen when compared to the electrolysis pathway, which is currently standing at the forefront of global energy transition policy.In sum, this manuscript offers an ecosystem analysis of the biogas industry through the lens of its evolution across time, from past to future, particularly focusing on legal and market perspectives, to highlight this industry’s pivotal role in meeting future energy demands.

“…Since mid-2021, there has been a reduction in the proportion of methane present in natural gas, which is largely attributable to a corresponding increase in the concentration of ethane [23]. Further changes in the composition of natural gas transported through the transmission grid are anticipated, particularly due to the injection of renewable gases such as biomethane and hydrogen into the grid [24][25][26][27][28]. In 2022, global demand for hydrogen increased to 95 million tons.…”

Thanks to investments in diversifying the supply of natural gas, Poland did not encounter any gas supply issues in 2022 when gas imports from Russia were ceased due to the Russian Federation’s armed intervention in Ukraine. Over the past few years, the supply of gas from routes other than the eastern route has substantially grown, particularly the supplies of liquefied natural gas (LNG) via the LNG terminal in Świnoujście. The growing proportion of LNG in Poland’s gas supply leads to a rise in ethane levels in natural gas, as verified by the review of data taken at a specific location within the gas system over the years 2015, 2020, and 2022. Using measurements of natural gas composition, the effectiveness of the steam hydrocarbon reforming process was simulated in the Gibbs reactor via Aspen HYSYS. The simulations confirmed that as the concentration of ethane in the natural gas increased, the amount of hydrogen produced, and the heat required for reactions in the reformer also increased. This article aims to analyze the influence of the changes in natural gas quality in the Polish transmission network caused by changes in supply structures on the mass and heat balance of the theoretical steam reforming reactor. Nowadays, the chemical composition of natural gas may be significantly different from that assumed years ago at the plant’s design stage. The consequence of such a situation may be difficulties in operating, especially when controlling the quantity of incoming natural gas to the reactor based on volumetric flow without considering changes in chemical composition.
