ICP2019 Flyer 1st Announcement (PDF) CONFERENCE OUTLINE The main objective of the polygeneration concept is to create a sustainable energy society based on a combination of energy savings, efficient use of fossil fuels and increasing the use of renewable energy. The polygeneration approach focuses on the basis of delivering more than one form of energy to the final user. The energy supplied to the system could be provided by conventional sources, including fossil fuels, renewable energy or a combination of them. For example: electricity, heating, cooling and dehumidification can be simultaneously delivered from one polygeneration plant. Polygeneration are highly energy integrated systems covering conventional cogeneration, trigeneration, as well as technologies for producing fuels and other valuable sub-products such as potable water and dry air, among others. SCOPE The fifth International Conference on Polygeneration, (ICP 2019) primarily aims at bringing together scientists and experts in polygeneration systems based on both renewables and conventional fuels. In addition to these systems, the following related technological advancements are included: fuel cells, heat pumps, sorption systems as well as other energy conversion and/or storage systems. Furthermore, common concerns including materials reactivity, heat and mass transfer, durability, stability under high-temperature and severe conditions, and system economic analysis, will be considered. The scope is to provide researchers with different aspects of multi-dimensional processes in energy conversion and to promote a multidisciplinary interexchange of ideas across subjects. CALL FOR PAPERS Extended abstract(s) related to the above topics are invited and the submission deadline is November 15, 2018.
