Hydrogen production companies are currently at the forefront of the global energy transition, and understanding their diverse approaches requires looking at a range of industry players, from traditional energy giants to nimble tech startups. One of the most prominent names in this space is Air Liquide, which has been investing heavily in carbon capture and water-splitting processes. Their strategy involves building large-scale hydrogen plants that serve manufacturing sectors and, increasingly, the mobility market. Similarly, an American multinational has made headlines with its massive green hydrogen project in NEOM, aiming to produce carbon-free industrial hydrogen production using solar and wind power. This project alone demonstrates how legacy chemical companies are pivoting to become leaders in the low-carbon economy.

On the other hand, dedicated green H2 producers like Plug Power are carving out a distinct niche.
