Biogas and biomethane
Investing in biogas assets, particularly biomethane, is now – along with investments in solar and wind power – not only helping to reduce and, in the long term, become less dependent on natural gas imports from Russia, but is also an excellent way to contribute to slowing observed climate change by reducing CO2 emissions.
Kaplonosy Project
Our Group is currently constructing its first 1 MWe agricultural biogas plant in Kaplonosy, Lublin Province. The biogas plant is scheduled to start up in July 2024. The biogas plant will help reduce emissions of about 4,000 tons of CO2 per year by replacing fossil fuel energy with renewable energy.
The biogas production technology at the Doral biogas plant under construction is based on the process of anaerobic wet fermentation of agricultural feedstocks. The plant will use wet technology with the use of digesters, in which the process of mixing substrates and producing agricultural biogas due to biochemical transformations of organic matter will take place. The process will be conducted at temperatures in the range of 38 – 42℃ (mesophilic fermentation). The process of anaerobic decomposition of organic matter contained in biomass will produce biogas and liquid digestate, which has fertilizing properties characterized by a favorable concentration of mineral components compared to raw materials before fermentation and which is used in fertilizing agricultural fields. The fermentation process will take place in airtight tanks, with no harmful impact on the environment. The methane fermentation process consists of a series of biochemical processes occurring without oxygen. Biomass decomposes into less complex substances. The gas emitted in the process of biomass decomposition is collected in sealed domes above the process tanks then is purified in a biogas treatment plant and transported by pipeline to an engine that converts it into electricity and heat. Electricity will be supplied to the national power system, and heat will be used for the biogas plant’s own needs and in the dryer. This happens in one technological process. The biogas obtained is qualified as a source of renewable energy. The digestate will be stored in sealed storage tanks during the winter, and during periods of fertilization, it will be transported to agricultural fields. The technological process of biogas production is solved in such a way that the mass circulation is closed and does not cause emissions of substances, including odors into the atmosphere. An essential part of the technological process is the use of renewable raw materials, such as: substrates as by-products of agri-food processing, waste substrates, biomass or plant silage. For substrate storage, storage tanks and silos designed on the biogas plant site are used. For liquid feedstock storage, sealed process tanks will be used.
