Johnson Jimba

Postdoctoral Research Associate

School of Engineering & Physical Sciences, Institute of Mechanical, Process & Energy Engineering, Heriot-Watt University, Riccarton, UK

Office: DB 1.56F



Research Profile


Johnson has a background in Mechanical Engineering after completing his undergraduate degree from the Federal University of Technology, Minna Nigeria. His undergraduate project focused on a zero-emission vehicle. At this time, he worked with a team at his university to develop an indigenous solar-powered vehicle using a combination of locally sourced and refurbished automobile materials. Johnson completed his MSc in Renewable Energy Engineering from Heriot-Watt University in 2019 with a distinction. His final dissertation focused on the energy requirement for capturing CO2 based on hydrotalcite adsorption technology. Johnson’s findings presented a preliminary understanding of the techno-economic performance in terms of the energy penalty of CO2 capture using hydrotalcite adsorption technology, specifically in cement plants. Johnson recently completed his PhD in Heriot-Watt University, and he continued working as a postdoctoral research associate in the Research Centre for Carbon Solutions (RCCS), Heriot-Watt University. He specialises in single-phase gas flow measurement of CCS mixtures and green energy carriers. He current research has been focused on both Coriolis metering applications and differential pressure meters, and he has the responsibility for the integrity and traceability, and uncertainty budget of the HWU flow facility.
