Organic Rankine Cycle for Energy Recovery System

Dear Colleagues,

Organic Rankine Cycle (ORC) is an emerging energy system for power production and waste-heat recovery. In the future, this technology can play an increasing role within the energy generation sectors, and it can aid the achievement of the carbon footprint reduction targets of many industrial processes. In particular, there is still a huge amount of un-used hot streams in various stationary power generators, and in several highly intensive industries, that could be recovered. Additional applications can come from the transportation sector, where engine-wasted heat in heavy vehicles can be used to achieve fuel savings. Moreover, low and high enthalpy flows from renewable sources (solar, geothermal, etc.) can be exploited in thermodynamic cycles based on Rankine architecture.

The ORC is already a well-proven option for large plants, but not all technological aspects are currently solved/optimized; the state-of-the-art still requires cost-effective improvements, in order to enlarge market opportunities. Meanwhile, the ORC is still developing in small-scale and/or micro-generation applications, in which efficient and low-cost components are not fully ready for the market yet and problems must be solved.

This Special Issue will focus on the current state-of-the-art and on cutting-edge research activities ongoing in ORC technology. Topics of interest for publication include, but are not limited to, the following:

• Waste-Heat Recovery applications
• Advanced thermodynamic cycles
• Combined heat and power generation
• Expanders for waste-heat recovery
• Renewable heat and low-enthalpy applications
• Experiments on micro ORC generators
• New organic fluids for power generation
• New integrations of ORC with other energy systems

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-anonymized 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.
