Enhancing energy security and flexibility

ENGIE is convinced that the alliance between the electron and the molecule — meaning gas and electricity — is the most reliable and cost-effective solution to achieve net zero carbon by 2045. The intermittency of renewable generation means that natural gas has a continued role to play in maintaining energy security. Storengy is committed to ensuring that natural gas remains a reliable bridge fuel, helping to stabilise the grid while supporting the transition to a greener future.

As the UK decarbonises its gas supply, ENGIE is pioneering innovative, low-carbon gas storage solutions, including hydrogen. These advances are essential for building a sustainable and secure energy system for the future.

Sustainability and innovation in natural gas

While natural gas plays a critical role in today’s energy mix, Storengy is also focused on advancing sustainable practices and minimising environmental impact. As part of ENGIE’s commitment to decarbonisation, we are exploring new technologies and innovative solutions that will make natural gas more sustainable, including the integration of biogas and green hydrogen into our storage systems.

We are also investing in projects that aim to reduce methane emissions and optimize the efficiency of our storage infrastructure. Storengy is dedicated to evolving natural gas solutions to meet the growing demand for cleaner, more sustainable energy.
