Ammonia derived from natural gas is essential for fertilizer production, which supports global agriculture and food security. Plastics and synthetic materials also rely heavily on natural gas derivatives, making it integral to modern manufacturing supply chains.

Enabling Technological Innovation

The availability of affordable natural gas has spurred technological advancements in industrial processes. For example, combined cycle gas turbines (CCGT) have revolutionized power generation by achieving high efficiency and rapid start-up times. Industries have also developed gas-to-liquids (GTL) technologies, converting natural gas into liquid fuels and chemicals, expanding its utility. Moreover, natural gas is increasingly used as a fuel for hydrogen production through steam methane reforming, which is pivotal for the emerging hydrogen economy.
