Going Carbon Neutral and Carbon Negative through Thermochemical Conversion of Biomass

Dear Colleagues,

A viable alternative to fossil fuels is represented by biomass, which is an abundant and dispatchable source of renewable energy. Moreover, this energy source enables a net-zero carbon balance, since the amount of carbon dioxide produced during the combustion process is virtually entirely used for oxygen production during photosynthesis. Additionally, capturing CO₂ during the production of energy or energy vectors from biomasses enables carbon removal because the carbon dioxide that is absorbed during growth is not re-released but, instead, captured and removed from the natural carbon cycle.

Encouraging ways to transform biomass into energy and energy vectors are pyrolysis and gasification processes, which have been demonstrated to be efficient and environmentally friendly methods.

For this Special Issue, we invite papers that consider the various aspects of converting biomass waste by means of pyrolysis and gasification into valuable products, with special attention to experimental and simulation works that investigate new processes and technologies at relatively high technological readiness levels (industrial and pilot scales) as well as the pretreatment and upgrading processes realized to enhance the productivity and efficiency of thermochemical conversion.

Topics of interests include but are not restricted to:

• biomass pyrolysis and upgrading processes;
• integrated pyrolysis systems;
• hydrogen from biomasses;

• advanced biomass pretreatment (e.g., hydrothermal carbonization, torrefaction);
• advanced cleaning and conditioning (e.g., plasma-enhanced catalytic oxidation, membranes);
• gas treatment and carbon capture processes;
• advanced/integrated electrical/thermal energy cogeneration (e.g., chemical looping gasification; carbon capture, storage, and use; power to gas);
• techno-economic assessment studies for optimization of the integrated system and life cycle assessment;
• modeling, thermodynamics, and process simulation.

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 250 words) can be sent to the Editorial Office for assessment.

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.
