Plug is the Leader in the Green Hydrogen Economy
Hydrogen is the molecule of the green energy revolution — At Plug, we defend it, advocate it and engineer what it takes to deliver complete systems to customers around the world.
Since our founding in 1997, Plug has led the Hydrogen Revolution. We believe that providing access to affordable and reliable green hydrogen energy is key to building a world that is sustainable for generations to come.
With that belief in mind, Plug is bringing the advantages of the total, end-to-end green hydrogen ecosystem — from production, storage and delivery to energy generation — to customers around the world because we’ve seen first-hand how global clients have reaped the tremendous economic and environmental benefits from transitioning to green hydrogen, which have then benefited the communities and industries they serve.
We’re on a mission to help as many customers as possible upgrade to green hydrogen energy. When you think about a greener world — think Plug.
