Helen has over 40 years’ experience in the energy industry and is an expert on gas purchasing, supply, shipping and regulation in the UK and Ireland.

Her roles in trading, gas shipping and pricing means she has a very commodity-centric view of energy markets. She founded Ceres Energy in 2008 with a former colleague with the intention of using the spare capacity in her company and his business contacts in Ireland.

She was managing director since inception and became chief executive officer in 2022. Previously, in 2000, she founded a company to provide consultancy and trading services to E&P companies; notable clients included Tullow Oil and Sterling Resources. That company effectively merged with Ceres in 2018. In the mid 90’s, she worked at Northern Electric where she was responsible for creating and managing the gas trading and shipping operation, a role which included negotiating and then operating major gas and power contracts as well as regulatory and policy matters. She gained her initial expertise in long term gas purchase contracts at British Gas in the early 1990’s.

She started her career as an oil refiner at Texaco Canada and then as a principle investigator at the Institute for Hydrogen Systems.
