Dear Colleagues,

There is a growing need to meet our energy demands through sustainable methods with minimal impact on our environment. In particular, ways to minimize carbon emissions are urgently needed. One potential route to achieve this, especially for transportation fuel, is to harness the power of algae biotechnology. Algae are photosynthetic microorganisms that can be used to convert solar energy into biological or chemical forms of energy, and develop processes that are potentially carbon neutral, or even those with a carbon deficit. Algae also offer viable routes for harnessing solar energy in the form of chemical energy that is suitable for storage and transportation. Whilst the more popular conceptual route to energy generation from algae has been using it to accumulate lipids and produce biodiesel, algae can potentially be employed to derive other forms of energy too. These include hydrogen production by cyanobacteria, and the use of algae biomass as a carbon neutral feedstock in biochemical conversion routes to produce biogas, bioethanol or biobutanol, or thermochemical conversion routes to produce bio-oil, syngas and combustible carbon. There are technological challenges in each of these routes, with respect to achieving economic and environmental sustainability in the process adopted to serve as a viable alternative to fossil fuel-derived energy. Challenges include maximizing carbon uptake by algae, maximizing yields of desired products, and engineering sustainable solutions. This Special Issue focuses on current technical advances in algal biotechnology that would bring the different options closer to the reality of sustainable energy generation.

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.
