International Workshop for Sustainable Energy Conversion Systems 2024

organized by The Heat Transfer Society of Japan.


The Heat Transfer Society of Japan will hold "The International Workshop on Sustainable Energy Conversion Systems (IWSEC) 2024" co-located with The 61st Japan Heat Transfer Symposium (May 29 - 31, 2024, Kobe). This workshop will focus on emerging sustainable energy conversion systems, including de-carbonized energy careers, fuel cells, water electrolysis, secondary batteries, and thermal and chemical energy storage systems. We will share cutting-edge research and development and discuss future perspectives.

Call For Papers


In this workshop, we invite the research community in heat and mass transfer to submit works related to the sustainable energy conversion systems, revolving around the following topic areas:

The list above is by no means exhaustive, as the aim is to foster the debate around all aspects of the suggested sutainable energy converstion systems.



Papers should be formatted according to the The 61st HTSJ Symp. formatting guidelines and submitted as a single PDF file. We welcome submissions across the full spectrum of theoretical, experimental and practical work including research ideas, methods, tools, simulations, applications or demos, practical evaluations, and surveys. Submissions that are 1 page long and more (including references and appendices) will be considered for an oral or poster presentation.

Authors who are willing to make a presentaiton must be registered by Jan 26 19 , 2024 via a Google Form


Note: ID and password for registered participants is needed for the access.
