Enagás, S.A., headquartered in Madrid, is Spain’s natural gas transmission system operator. The company plans, builds, owns and operates the high‑pressure gas pipeline network, LNG regasification terminals, and underground storage facilities, providing transport, regasification and system operation services that support national energy supply and industrial demand. Enagás also holds interests in gas infrastructure and related services outside Spain.
Through its subsidiary Enagás Renovable, the group develops renewable gas projects—particularly green hydrogen and biomethane—and works to integrate these gases into networks and industrial clusters. Its activities are relevant to the chemical value chain by enabling reliable supply of methane and LNG for energy and feedstock, and by advancing hydrogen infrastructure that can support lower‑carbon production of ammonia, methanol and other basic chemicals. Enagás collaborates with public and private partners on large‑scale projects and network planning aligned with European decarbonization objectives and Spain’s energy transition strategy.
