Hydrogen has moved from a futuristic concept to a cornerstone of the global clean-energy transition, and hydrogen stocks are gaining momentum as investors take notice.
From powering trucks and factories to storing renewable energy, the hydrogen economy is expanding fast and investors are starting to take notice.
In 2025, the hydrogen revolution has shifted into high gear.
According to data from the Hydrogen Council and McKinsey, more than 500 clean-hydrogen projects are now in development across the globe, representing well over $100 billion in committed investment. The International Energy Agency notes that hydrogen is emerging as one of the fastest-growing segments of the global energy transition, fueled by aggressive climate policies and industrial demand.
Below, we spotlight 10 leading hydrogen stocks driving this transformation – from global industrial giants scaling infrastructure to next-generation innovators – pushing the boundaries of hydrogen technology.
What Is Hydrogen and How Can It Power the Future?
Hydrogen is the most abundant element in the universe and one of the most versatile energy carriers ever developed. When used as a fuel, it produces electricity and water vapor, with zero carbon emissions.
Hydrogen can be produced in several ways:
- Gray hydrogen is made from natural gas and releases carbon dioxide.
- Blue hydrogen also comes from natural gas but captures and stores the emissions.
- Green hydrogen is created by splitting water using renewable electricity, producing a completely carbon-free fuel.
Hydrogen’s greatest strength is its flexibility. It can store large amounts of energy, power long-distance transport, and support heavy industries that are difficult to electrify. Trucks, ships, airplanes, and steel plants can all operate on hydrogen, making it vital for deep decarbonization.
As technology advances and costs fall, hydrogen is increasingly seen as the missing link in the clean-energy transition. It has the potential to connect renewables, transportation, and manufacturing into a single, sustainable energy system for the future.
