The National Gas app is designed for iPhone users to provide insights into the operation of Great Britain's National Transmission System (NTS), which spans approximately 5,000 miles. This application enables users to access real-time data regarding gas sources and demand across the country. It aims to engage customers and stakeholders with interactive charts that reflect the current gas supply and demand dynamics.

With a focus on transparency and education, the app highlights the significance of the gas system in energy transportation. As one of the largest gas transmission networks globally, the NTS plays a critical role in delivering energy safely and reliably. The app also outlines future plans for repurposing parts of the network to support hydrogen or carbon dioxide transport, aligning with the UK's net zero targets and promoting a sustainable energy future.
