Simon Gant is a Technical Fellow in the Fluid Dynamics Team at the Health and Safety Executive’s (HSE) Science and Research Centre. His main areas of interest are in dispersion modelling and consequence assessment. Simon is chair of Atmospheric Dispersion Modelling Liaison Committee (, which comprises around a dozen experts drawn from Government departments (e.g., the Environment Agency, Met Office, UKHSA) plus the energy company EDF and consultancy RiskAware. He has been involved in various CCS-related projects over the last 18 years at HSE, including CO2PipeHaz and COOLTRANS. In 2017, he led a review of HSE’s work on CCS, which is documented in a report available here:

Zoe Chaplin is a Principal Risk Scientist at the Health and Safety Executive’s (HSE) Science and Research Centre. She has a particular interest in major accident hazard (MAH) pipelines and is responsible for the on-going development of HSE’s MAH pipelines risk assessment modelling tool. She is also a member of an Institution of Gas Engineers and Managers (IGEM) standards panel on natural gas pipeline risk assessment.

Zoe is actively involved in projects relating to the conversion of the natural gas network in the UK to hydrogen and the associated carbon capture and storage. This includes industry-led projects and those from other government departments, as well as the updating of HSE’s risk assessment models to make them suitable for both hydrogen and carbon dioxide.

Adrian Topham is Senior Development Manager CCUS, at The Crown Estate.

Adrian’s role as sector lead is to help create a pipeline of geological COstorage prospects that delivers CB6 targets and meets market expectations, while playing a lead spatial planning role to optimise seabed use between CCUS, wind and other sectors.His previous experience as an engineer, team leader, general manager and now development manager stems from academic training in chemical and petroleum engineering. He has worked as a reservoir engineer, aiding hydrocarbon extraction in many countries and is now committed to the carbon cycle and returning the by-products after use to the subsurface.Adrian’s CCUS sector interests are both technical (geophysical, geomechanical, geological) and economic (capture feasibility, transportation, removals). He is currently involved in supporting research into windfarm / seismic monitoring interaction.

Fatemeh has more than 17 years of experience in Energy industry. Currently she is the Director of Hydrogen and CCS Business Development at Air Products where she works with a range of global customers across the energy value chain on topics related to the Energy Transition. Prior to this role, she was the Venture Owner of Carbon Capture Technologies at Siemens Energy Incubator where she developed technology development and go-to-market strategies to build the CCS business for which she successfully pitched the business to potential investors to raise sufficient fund to take the venture to the next level up to the “Exit/Launch” phase.Fatemeh’s background is Mechanical Engineering, she has Masters in Renewable Energy from Heriot-Watt university and PhD in Carbon Capture Technologies from the University of Leeds in collaboration with the University of Texas at Austin.
