The surge in data center construction driven by the A.I. boom is leading operators to explore alternative energy sources like green hydrogen to power their energy-intensive servers. Green hydrogen, produced through electrolysis using renewable electricity, is gaining traction as a carbon-free fuel for data centers. Companies like Microsoft are already testing hydrogen fuel cells, and green hydrogen producers like Q Hydrogen and Plug Power are witnessing a surge in demand from data centers. Q Hydrogen is set to open a commercial renewable hydrogen power plant in New Hampshire, with the potential to fuel data centers using clean hydrogen-powered generators. Plug Power is exploring delivering green hydrogen to off-site data centers to meet their increasing energy needs. While green hydrogen offers a promising solution for reliable, off-grid power supply, challenges remain such as high costs, storage, and transportation difficulties. Some experts believe green hydrogen could serve as backup energy during extreme weather events but acknowledge the current hurdles in widespread adoption.
