Blue Hydrogen

« Back to Glossary Index« Back to Previous Page

Definition:
Hydrogen produced from natural gas through steam methane reforming (SMR), with the associated carbon dioxide emissions captured and stored to reduce environmental impact.

Key Components:

  • Steam Methane Reforming (SMR): A process that extracts hydrogen from natural gas.
  • Carbon Capture and Storage (CCS): Technology that captures and stores carbon emissions underground.

Use Cases/Industries:

  • Power Generation: Providing a cleaner fuel alternative for electricity production.
  • Industrial Heating: Supplying heat for manufacturing processes with reduced emissions.

Advantages:

  • Lowers Carbon Footprint: Reduces CO₂ emissions compared to traditional hydrogen production.
  • Leverages Existing Infrastructure: Utilizes established natural gas networks.

Challenges:

  • High Costs of CCS Technology: Carbon capture requires significant investment.
  • Potential for Methane Leakage: Natural gas extraction can contribute to greenhouse gas emissions.

Related Terms:
Steam Methane Reforming, Carbon Capture and Storage, Fossil Fuels

Example:
A natural gas facility in Texas retrofitted with CCS technology now produces blue hydrogen, cutting carbon emissions by 60% compared to conventional methods.
