Bio

Prof. Yunting Ge is a Professor of Building Services Engineering in the School of The Built Environment and Architecture at London South Bank University in the UK. He is also the Director of the Centre for Civil and Building Services Engineering (CCiBSE) at the University. Previously, he worked periodically as a lecturer, senior lecturer, reader, and professor at Brunel University London and the University of South Wales. He gained his BSc, MSc, and Ph.D. degrees from Xi’an Jiaotong University (BSc, MSc) and Tsinghua University (Ph.D.) in the field of Thermofluids, Energy, Hydrogen, and Built Environment.
 Prof. Ge has accumulated over 25 years of research and development experience in Built Environments, Energy Conversation Technology, Hydrogen, and Thermofluids. He has unique skills in modelling development for buildings, different energy systems, and components. He has also developed a CO2 transcritical compressor model which has been used by a famous commercial software ‘Energy Plus’. Many of his heat exchanger design software has been utilised by companies across the UK. In addition, he has developed a supermarket energy control system model which has been widely recongnised. He is currently leading some research projects funded by EPSRC & Innovate UK. As a principal investigator (PI), he has obtained more than £5.16m of research funding to support his various projects. As a Co-investigator, he has also contributed to and been involved in a number of funded research projects with total values above £11.3m. So far, he has supervised more than 11 Ph.D. students and several post-doctoral research fellows. Furthermore, he has published over 150 peer-reviewed scientific journals and conference papers. Externally, he is the President of IIR Commission E1 (International Institute of Refrigeration). He is an associated editor of an Elsevier Journal- Energy Report. He has been also a committee member of several international conferences.

Title

Performance analysis of high-temperature metal hydride heat pump

Abstract

In an energy-intensive industrial site such as a steel plant, there is plenty of medium and low-temperature waste heat that could be recovered for heating purposes with advanced and feasible technologies for example metal hydride (MH) heat pumps.   Compared to other heat pump systems such as those with compression and absorption cycles, the MH heat pump has some distinctive advantages including a low carbon system in terms of less electricity input and environmentally friendly working mediums, compactness, and most importantly achievable heat output with relatively high temperature.  However, it is noted that there are some key challenges involved in this technology including identification of applicable MH alloys and their characterizations, control optimizations of transient system operations, and comprehensive understanding of dynamic mass and heat transfer for hydrogen absorption and desorption processes. Correspondingly, these challenges have been addressed by the project developments of alloy identifications with thermodynamic analysis, correlation models for alloy characterizations, dynamic MH heat pump models and validations, CFD models of MH reactors, and experimental investigations.  Some of the project developments will be presented and discussed.  The project outcomes can produce very useful research data for future development in this area.  Meanwhile, they can contribute significantly to the optimal designs and controls as well as actual applications for the high-temperature metal hydride heat pump.
