Future-proof your business with green hydrogen.

The green hydrogen produced by Ohmium LotusTM electrolyzers is versatile, with applications in small and large industry, transportation, and power. We design modular hydrogen solutions that help your business maximize operational efficiency, energy security, cost reduction, and sustainability.

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

Brown hydrogen is produced by using coal or lignite. Roughly 19 tonnes of CO2 are emitted when 1 tonne of brown hydrogen is produced.

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.

Green hydrogen is produced using clean, renewable energy, without releasing CO2 emission.

Did you know?

Green hydrogen directly reduces your carbon footprint.

Every MW of green hydrogen electrolyzers used in place of brown Hydrogen has the equivalent CO2 abatement power of up to 150,000 trees.
