I enjoy working on Hydrogen energy, energy storage & carbon capture technologies. I have industrial experience to apply the principles of thermodynamics, computational fluid dynamics, electro-chemistry, heat & mass transfer, and system integration over the past 17 years at my own companies.
I have worked on hydrogen production from water, hydrogen fuel cells, gas compression, biogas production, biogas upgrading into bio-methane, capturing Carbon di Oxide from various sources using water scrubbing, and pressure swing absorption methods. I have experience on high pressure storage of hydrogen and bio-natural gas (Bio-CNG). I have studied the super critical fluid properties of CO2 at high pressure.
While developing fuel cell and electrolyser technologies at my own companies I have gained experience on mathematical modelling of fluid flow through very thin channels and fine pores for designing of bipolar plates and electrodes. This helped my understanding of the characteristics of gas bubble movement, capillary action, fluid viscosity and rheology under various temperatures and pressures. I have developed catalyst ink for electrodes using solvent, carbon powder, metal-catalyst, binders etc.
I have two international patents granted on electrolyser for hydrogen production as the sole inventor and owner.
My first degree was in Civil Engineering with specialisation on Environmental Engineering (1990-1994) from India. I then took my Masters Degree on Energy Engineering from India which gave me an exposure to both conventional and non-conventional energy systems (1999-2001). I then completed my PhD (2002-2006) on electrolysers for hydrogen production from water and hydrogen fuel cells from Loughborough University, UK at the Centre of Renewable Energy Systems Technology (CREST), Department of Electrical and Electronic Engineering. I have also completed my MBA from Surrey University Business Schools, UK in 2015.
I then started my career at the age of 23 years as a Lecturer in Civil Engineering at the National Institute of Technical Teachers' Training and Research, India (1995-2002) http://nitttrbpl.ac.in to provide training programmes on advanced subject matters (on civil engineering) to industry personnel and academics (lecturers-professors) from various Indian Polytechnics and Universities.
I joined the School of Energy and Electronic Engineering at the University of Portsmouth, UK in September 2019 as a Senior Lecturer on Renewable Energy Systems. I am currently working with other colleagues to design brand new BEng, MEng and MSc courses related to Energy Systems at the University of Portsmouth which will be launched in due course.
My Research & Business activities:
I completed my PhD at Loughborough University. I have been instrumental to build the UK's first large scale wind-hydrogen energy storage scheme of 8 MWh capacity at West Beacon Farm, Loughborough, Leicestershire. This large project was co-funded privately and I have then formed my first spin out company, Bryte Energy (2005-2009) from Loughborough University, with my two other co-researchers. At Bryte Energy I have done long term forecasting of energy systems including the future role of hydrogen energy. I have provided consultancy services to large utility companies. I have done due dilligence reports on energy technologies for investment bank/ VC funds.
AFC Energy Plc (2006-2009):
After completing my PhD on electrolyser and hydrogen fuel cells from Loughborough University in 2006, I started working at AFC Energy Plc from its inception (www.afcenergy.com), which is an alkaline fuel cell company. I led the development of fuel cell technology. I worked for 4 years (2006-2009) at AFC Energy as the Head of Fuel Cell Division responsible for electrode development, stack development and system integration; later on I became the Business Development Manager there. After floating AFC Energy Plc on the AIM market of London Stock Exchange I then started another company, RE Hydrogen Ltd.
RE Hydrogen Ltd (2009-2016):
As the founder, CEO, CTO I have developed novel electrolyser and hydrogen compressor at RE Hydrogen and completed several Innovate UK funded projects on hydrogen energy related technologies in collaboration with leading industrial and University partners. I have received Rushlight Industry Award for my contribution on hydrogen and fuel cell sectors in the UK. I have been a member of Green Hydrogen Standards Committee, appointed by the Department of Business Energy & Industrial Strategy- BEIS- UK Govt. I am also a member of the UK working group OIML on Gas Metering for Product safety & standards, appointed by BEIS.
Engas UK Ltd (2014-ongoing):
As the founder/CEO/CTO, I have developed a novel CO2 capturing technology from biogas, landfill gas, syngas, coalbed methane, crude natural gas, & dry the gas apart from compressing it up to 250bar. I have developed a novel biogas upgrading technology to produce biomethane fuel for vehicles, back up power. I have sold my own bio-CNG vehicles refuelling plants to the UK and India and established manufacturing partners under licensing.
