Danielle Stewart

Danielle is responsible for the development of National Grid Gas Transmission’s long term business strategy as the UK transitions to Net Zero.

A chartered engineer, she was a Finalist in the UK 2020 Top 50 Women in Engineering: Sustainability.

As Long Term Strategy Manager, Danielle supports and develops innovation projects that investigate alternative zero or low carbon sources of energy. She is currently leading the development of a collaborative programme of work to build the evidence base for hydrogen technology as a cleaner alternative to natural gas for use in homes, industry, power and transport. The outputs of this work will help to inform government policy and future energy network design. A regular speaker at conferences, she recently had the privilege of contributing to a panel at the World Energy Council Hydrogen Innovation Forum.

Danielle started her career at National Grid using simulation software to model gas flows on the UK’s gas transmission network to support operational decision making. Since then she has led projects to redesign two of the UK’s gas terminals, developed and managed a multi-billion-pound capital investment plan and led regulatory business plan submissions. Keen to develop others, she is proud to have established a new high-performing team of analysts and engineers to create gas system asset management and investment strategies.

Prior to the energy industry, Danielle was a published post-doctoral researcher in the Elementary Particle Physics Group at the University of Warwick. Working in international collaborations, her main area of focus was particle detector development where she coded simulations and ran experiments to optimise detector design. As a spin-off from her research, she investigated an alternative technology for solar panels.

Alongside her passion for sustainability, Danielle actively promotes inclusion and diversity. Danielle sits on the board of the UK Women’s Infrastructure Network, which creates opportunities for women to network, exchange ideas and shape the infrastructure agenda. She mentors a diverse range of people and works with the Kent Academies Network on a social mobility programme that supports high potential students from disadvantaged backgrounds to go on to higher education.

Danielle holds a PhD in particle physics, a first-class Masters degree in Maths and Physics and is currently completing an MBA at Warwick Business School. Outside of work she is a keen triathlete.
