Dr Jahedul Islam Chowdhury is currently a Research Fellow at the Centre for Energy Systems and Strategy, School of Water, Energy and Environment, Cranfield University. After completing a BSc in Mechanical Engineering from DUET in 2010, he was working as an Assistant Engineer in a 412MW gas turbine combined cycle power plant in Bangladesh. In 2013, he completed an MSc in Thermal Power and Fluid Engineering from the University of Manchester and then he completed his PhD in Mechanical Engineering from the Queen's University Belfast in July 2017. His PhD focused on the modelling and control of supercritical organic Rankine cycle based waste heat recovery systems for internal combustion engines to help mitigating greenhouse gas emissions and reducing energy consumption in industry and automotive sectors. His research interests focus on energy systems, low carbon technologies, waste heat recovery and conversion technologies, energy efficiency in industry and buildings, energy systems integration, optimization and control, energy storage and environmental impacts.

Current activities

OPTEMIN (Optimising energy management in industry)- EPSRC Project

OPTEMIN is a collaborative research project funded by the EPSRC to help reduce carbon emissions from UK industry. The project is led by Brunel University London in collaboration with Cranfield University, Univesity of Leeds and University College London. By working closely with the collaborators and industrial partners, OPTEMIN is developing methods to demonstrate the potential offered by energy efficiency, heat recovery and conversion to electrical or thermal energy, waste to energy conversion and energy integration. The overall project aim is to demonstrate, through research and case studies, the potential to reduce in excess of 15% carbon emission and energy demand in the UK industry.

The research programme at Cranfield University includes identification of energy efficiency potential in UK industry sectors and evaluation of emerging technologies for improving energy efficiency, develop an understanding of complex energy networks at three key levels: process or plant, overall site and national grid level and analyse their interactions based on data obtained from different industrial processes and sites. In particular,  OPTEMIN is investigating the potential of waste heat recovery from the iron and steel and food and drink industry by low and medium temperature power cycles such as Organic/steam Rankine cycle (ORC/SRC), supercritical COcycle, etc. and utilisation of biomass as an alternative to conventional fuels in steel reheating furnaces. 

Other research activities include: 

(1) Zero-carbon heating and cooling for railway stations  

(2) Grid-level energy storage for renewable integration and peak load management 

(3) Optimising energy management in new housing developments with low carbon technologies
