Hi, I am Stephen B. Harrison, founder and Managing Director at sbh4.

As an independent consultant, I am heavily involved in decarbonisation with a focus on CCUS, GHG emissions reduction and the emerging hydrogen economy. In the hydrogen domain, my expertise stretches the full value chain from upstream production of grey, blue, turquoise, and green hydrogen though midstream storage and distribution of hydrogen to industrial applications in refining, steel making and mobility. For CCUS, I focus on carbon dioxide capture from power generation and heavy industry, for example cement making, ammonia, methanol, and the energy sector. I am also expert in the areas of CO2 purification, compression, liquefaction, distribution, and utilisation. Additional pillars of decarbonisation where I advise are renewable power generation, sustainable energy, and the electrification of industrial processes to avoid fossil fuel combustion.

My professional background extends over 30 years. Of those, 16 were in the UK with The BOC Group plc, a FTSE 100 company. More recently, I worked for 10 years in Munich with Linde AG, a DAX30 organisation. As a result of this international experience, I am bilingual in English and German and I have dual nationality.


For more than half of my career, I have championed and led a niche Specialty Gases business within these two Industrial Gases giants. So, I have experienced the big corporate environment and the more intimate small firm culture that thrived in the specialties division.


Through my involvement in industrial gases, I have had deep exposure to a diverse range of products, including hydrogen, carbon dioxide, air gases and helium. Medical gases, fuel gases, welding gases, beverage dispense gases, specialty gases and refrigerant F-gases were also in my business portfolios at BOC and Linde for many years. Equipment, such as two product ranges of hydrogen PEM electrolysers for hydrogen production, high purity gas control equipment and gas cylinders of all sizes and types were integral to the businesses that I led.

Since 2017, I have been running my own consulting practice at sbh4. I maintain close contact with the hydrogen and industrial gases sectors through my consulting activities and my work with gasworld & H2 View, where I am a member of the advisory boards for both of these leading international publications which are focused on hydrogen, industrial, specialty and medical gases.
