Special Issue Information

Dear Colleagues,

Biogas upgrading, utilization, and storage have become critical components in the global transition towards sustainable energy systems. Recent advances have focused on enhancing the efficiency, cost-effectiveness, and environmental performance of biogas technologies. Biogas upgrading involves the removal of impurities such as carbon dioxide (CO2), hydrogen sulfide (H2S), moisture, and siloxanes to produce biomethane with a high methane (CH4) content, suitable for grid injection or use as vehicle fuel. Emerging technologies, including membrane separation, cryogenic distillation, and advanced adsorption techniques, are driving improvements in energy efficiency and process reliability.

The utilization of upgraded biogas spans various sectors, from electricity and heat generation to transportation and industrial applications. Innovations in combined heat and power (CHP) systems, fuel cells, and bio-LNG (liquefied biomethane) are expanding the versatility and economic viability of biogas.

Storage solutions are equally crucial, addressing the intermittent nature of biogas production and demand. Advances in high-pressure storage, underground storage, and chemical conversion to synthetic natural gas (SNG) are enhancing the flexibility of biogas and its integration into energy networks.

This Special Issue will explore the latest technological developments, current challenges, and future perspectives in biogas upgrading, utilization, and storage, emphasizing the role of these technologies in achieving energy security and reducing greenhouse gas emissions.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Renewable energy sources (RES) are the foundation of the ongoing energy transition in Poland and worldwide. However, increased use of RES has brought several challenges, as most of these sources are dependent on weather conditions. The instability and lack of control over electricity production lead to both overloads and power shortages in transmission and distribution networks. A significant advantage of biogas plants over sources such as photovoltaics or wind turbines is their ability to control electricity generation and align it with actual demand. Biogas produced during fermentation can be temporarily stored in a biogas tank above the digester and later used in an enlarged CHP unit to generate electricity and heat during peak demand periods. While demand-driven biogas plants operate similarly to traditional installations, their development requires navigating regulatory and administrative procedures, particularly those related to the grid connection of the generated electricity. In Poland, it has only recently become possible to obtain grid connection conditions for such installations, following the adoption of the Act of 28 July 2023, which amended the Energy Law and certain other acts. However, the biogas sector still faces challenges, particularly the need for effective incentive mechanisms and the removal of regulatory and economic barriers, especially given its estimated potential of up to 7.4 GW.
