Overview, Challenges and Current Trends in H₂ Energy, Gasification, Waste and Biomass

Dear Colleagues,

Hydrogen (H₂) energy, gasification, waste, and biomass are all areas of increasing interest due to the need for cleaner and more sustainable energy sources. H₂ energy involves the use of hydrogen as a fuel, either through combustion or in fuel cells, to generate electricity. Hydrogen is also used as a reductant and valuable precursor for chemical industries. Gasification involves the conversion of solid or liquid fuels into syngas that can be used for energy production or chemicals. Waste and biomass involve the use of organic materials, such as municipal solid waste or plant matter, to generate energy.

However, there are several challenges associated with the use of H₂ energy, gasification, waste, and biomass. Among the many current technological challenges is the cost of implementing these technologies, as they often require significant investment in infrastructure and equipment. In addition, these technologies can be relatively inefficient, particularly in the case of gasification and waste-to-energy, which can result in relatively high emissions. Another challenge is the need for reliable sources of feedstock, particularly in the case of biomass, which requires a steady supply of plant matter or other organic materials.

Despite these challenges, there are several promising trends in the field of H₂ energy, gasification, waste, and biomass. One of the most significant trends is the increasing use of renewable energy sources, such as wind and solar power, to generate the electricity needed to produce hydrogen. In addition, there is a growing interest in the use of waste and biomass as feedstock for energy production, as these materials are often readily available and can be used to generate energy in a relatively sustainable manner. Finally, recent research into the development of more efficient and cost-effective technologies for H₂ energy production, gasification, waste, and biomass could help us to overcome some of the challenges associated with these approaches.

We urge researchers around the world to contribute to this Special Issue by submitting high-quality research.

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. 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.
