Abigail Dombey is a carbon and sustainability engineer for Net Zero Associates. She recently led on a BEIS Industrial Fuel Switching (IFS) Feasibility project in the UK, trialling the deep decarbonisation of the brick manufacturing process by converting an existing gas kiln to run on hydrogen. The project was successful, producing the first bricks fired with 100pc hydrogen in a working kiln in the world. |

Brita Holstad is the chief operating officer and co-founder of Transitus Energy, which is involved in several projects to switch natural gas fuel with hydrogen. She leads the commercial discussions and co-leads the technical project definition. She has been credited with working out usage solutions for CO2 for Transitus, bringing forward the timing of projects delivery because they are no longer linked to a sequestration solution. |

Sarah Klimpton is vice president and low-carbon hydrogen lead for DNV’s energy systems business in the UK and Ireland. She draws on over 30 years’ experience working as a consultant to the natural gas industry with a focus on the impacts of gas quality on network operation, customers, and measurement systems, to demonstrate whether low-carbon hydrogen could safely replace natural gas. Together with industry partners and government, Sarah supports real-world tests at DNV’s Spadeadam R&D site in Cumbria to de-risk hydrogen and understand if it can be piped into people’s homes using existing natural gas infrastructure. |
