In the framework

What the capability covers and what it leaves to others, and the indicators it will be measured by.

Bounds

Covers the fuel technologies; production plants and distribution belong to Strategic Infrastructure, and fuel markets to the economic domains.

Lineage

Carried from v0.0 (formerly Hydrogen and ammonia for power) with the same identifier, absorbing Biofuels (retired): the capability is sustainable fuel technology as a class, with the pathways distinguished at the indicator layer.

Indicators

  • research publication share in hydrogen and fuelsResearch
  • electrolyser manufacturing capacityPending
  • low-carbon fuel production volumePending

Research

Papers classified to the capability, by year and by the nation of their authors' institutions, 2020–2024. Read from the v0.0 research topics Hydrogen and ammonia for power and Biofuels.
