Special Issue Information
Dear Colleagues,
The fight against climate change has come to a turning point. The EU efforts to reach climate neutrality by 2050 encompass not only the reduction of greenhouse gas emissions, but also the removal of carbon dioxide from the atmosphere. Among the proposed actions, bioenergy with carbon capture and storage (BECCS) is the most relevant for the energy sector. Bioenergy, as well as waste-to-energy (WtE), already plays a relevant role in limiting GHG emissions under a “life cycle” perspective. In fact, the produced/recovered energy saves on consumption of conventional energy sources and the associated GHG emissions. Furthermore, with the introduction of carbon capture technologies, net negative emission levels may be reached, providing an essential contribution to achieving the “net zero” target.
Several ongoing projects concerning carbon capture in WtE are exploring the potentials and implications of different capture technologies, as well as investigating innovative techniques. Biogas upgrading to bio-methane, or even to green hydrogen, although mostly on limited scale, already includes carbon dioxide removal. Biomass-fired power plants can find in the generation of “carbon credits” a way for supporting carbon capture costs, while qualifying for green electricity subsidies. Many aspects of this picture are still unclear and need deep investigation.
This Special Issue aims at investigating such unclear aspects, with analysis of novel solutions, as well as review papers with state-of-the-art findings that can deliver a significant contribution in assessing the potentials and implications of BECCS technologies. Even though the Special Issue is open to all contributions related to bioenergy, waste-to-energy, and their impact on climate change, potential focus areas are summarized as the following:
- Carbon capture techniques applicable to bioenergy and waste-to-energy systems;
- Assessments of GHG impacts also through life cycle assessment (LCA);
- Comparative analysis of different options, also entailing economic implications;
- Technologies applicable to specific streams (e.g., residual biomass, food waste, sewage sludge, sanitary waste);
- Gasification and pyrolysis associated with pre-combustion carbon capture techniques;
- Oxygen based thermal processes (e.g., oxy-combustion, chemical looping);
- Upgrading and conversion of biogas;

Manuscript Submission Information
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. Energies is an international peer-reviewed open access semimonthly 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 2600 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.
