Dr Jahedul Islam Chowdhury is currently a Research Fellow in Aero Systems Thermal Management at the Centre for Propulsion Engineering, School of Aerospace, Transport and Manufacturing, 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

Current Project: 

Powerplant Integration of Novel Engine Systems (PINES), funded by Innovate UK

Past projects: 

(1) OPTEMIN (Optimising  energy management in industry), funded by EPSRC 

OPTEMIN was a collaborative research project funded by the EPSRC to help reduce carbon emissions from UK industry. The project was 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  developed 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 was to demonstrate, through research and case studies, the potential to reduce in excess of 15% carbon emission and energy demand in the UK industry.

(2) Zero-carbon heating and cooling for railway stations funded by East West Railway (EWR) Company Ltd.: 

As the UK economy has planned to become net-zero by 2050, the importance of integrating renewables in economic sectors for both electricity and heat is becoming paramount. Especially for places like railway stations with moderate heating and cooling needs, heat pumps can offer an energy efficient and zero emissions solutions. In this project, we investigated the feasibility of heat pumps for heating and cooling of stations along the East West Railways (EWR) route  in techno-economic-environmental perspectives. 

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

With more and more renewable energy sources (RES) going into power grids, the balancing of supply and demand during peak times will be a growing challenge due to the inherent intermittency and unpredictable nature of RES. Grid level batteries can store energy when there is excess generation from wind and solar and discharge it to meet variable peak demand that is traditionally supplied by combined cycle gas turbine (CCGT) plants. This project assessed the potential of battery storage to replace CCGT in responding to variable peak demand for current and future energy scenarios (FES) in the UK from techno-economic-environmental perspectives.

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