Advanced Power Systems for Waste Heat Recovery

Dear Colleagues,

It is widely recognized that one of the most effective strategies in the short term to fight climate change is to promote energy efficiency by limiting fuel consumption and enhancing self-producing electricity with the final goal of reducing the carbon footprint of human activities. Waste heat recovery for power production is one of the key assets in this energy transition process towards a more sustainable society and can be applied to several sectors: from very large industries to small-scale on-board and domestic applications. Differently from other solutions for process decarbonization, like carbon capture, the implementation of waste heat recovery improves the overall system efficiency rather than involving a performance penalization while at the same time contributing to lowering the stress on the electrical grid thanks to self-production and self-consumption of electricity.

Several technologies are commercially available today for waste heat recovery at different scale and temperature levels and are mainly based on Organic Rankine Cycles, steam cycles and gas cycles. This Special Issue aims to present and disseminate the most recent advancements related to the theory, design, modeling, control and operation of advanced waste heat recovery power plants that would represent a step ahead with respect to the existing state-of-the-art in terms of performance, affordability, flexibility or operability. Topics of interest for publication include, but are not limited to:

• Non-conventional Organic Rankine Cycles (ORC) power plants;
• Supercritical carbon dioxide (sCO₂) power plants;
• Non-conventional steam Rankine power plants;
• Non-conventional open or closed gas cycles;
• Adoption of mixtures of fluids and their optimization;
• Adoption of thermal energy storage for power plant integration;
• Turbomachinery design for WHR plants;
• Volumetric expanders designed for WHR plants;
• Heat exchanger design for WHR plants;
• Optimal design methodologies;
• Advanced modeling approaches;
• System control and transient simulations;
• Real plant monitoring and performance assessment;
• Detailed cost structure and technoeconomic analysis.

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.
