Industry
Achieve operational resilience and long-term business sustainability
The majority of today’s hydrogen is produced with polluting natural gas. By switching from polluting gray or brown hydrogen to emissions-free green hydrogen, global industries can accelerate toward carbon-reduction goals.
- Methanol production
- Petroleum refining
- Steel and iron processing
- Ammonia production
Produced with 100% renewable energy, green hydrogen can help your business decarbonize operations while ensuring reliable long-term hydrogen supply.
Benefits of green hydrogen:
- Stabilize your hydrogen supply
- Decrease dependence on imported natural gas
- Ensure continuity of service
- Make progress toward carbon reduction targets
- Increase control over operational costs
Transportation
Decarbonize your fleet with sustainable, emissions-free fuel
The transportation sector is a significant contributor to global CO2 emissions. In the form of fuel by fuel cells or combustion engines, hydrogen can be used as a sustainable alternative to gasoline or diesel. Green hydrogen – produced by 100% renewable energy – is an emissions-free option for both large and small transportation applications.
- Light duty passenger vehicles
- Heavy duty vehicles such as trucks and buses
- Maritime transportation
- Aircrafts
- Trains
Benefits of green hydrogen:
- Replace polluting fuels like diesel and gasoline with emissions-free hydrogen
- Benefit from longer range, faster refueling, and higher payload than EVs
- Produce hydrogen-derived synfuels such as green ammonia, and methanol
- Reduce dependence on imported oil
Power
Maximize energy reliability with increased flexibility
Because it can be stored for long periods and converted to electricity on demand, hydrogen is used as a form of reliable energy storage. The added flexibility and energy resilience that it provides can benefit a wide range of commercial to grid-sized customers.
- Electric utilities
- Critical infrastructure (hospitals, data centers, telecom towers, etc.)
Stored green hydrogen – produced by 100% renewable energy – helps utilities mitigate renewable energy intermittency and other grid reliability issues. Green hydrogen provides critical backup power and creates a path to a more sustainable power grid.
Benefits of green hydrogen:
- Maximize renewable energy integration
- Stabilize fluctuations in power generation and power consumption
- Provide back-up power for grid disruptions
- Increase flexibility
The Hydrogen Rainbow
Green hydrogen is produced using clean, renewable energy, without releasing CO2 emission.
Gray hydrogen is produced using natural gas in a process called steam methane reforming (SMR). It roughly releases 10 tonnes of CO2 for every 1 tonne of gray hydrogen.
Brown hydrogen is produced by using coal or lignite. Roughly 19 tonnes of CO2 are emitted when 1 tonne of brown hydrogen is produced.
DID YOU KNOW?
Green hydrogen directly reduces your carbon footprint
Every MW of green hydrogen used in place of brown/grey hydrogen avoids significant CO₂ – equivalent to the carbon absorbed by tens of thousands of trees every year.
Every 1 MW of green hydrogen used reduces as much CO2 as:
