Zero-Carbon Fuel Monitor
Compare fuel solutions
The interactive charts for TRL, IRL and CRL below show how promising zero carbon and net zero fuel solutions compare on the readiness scales. You can also view the supporting evidence. First, choose TRL, IRL or CRL, then follow the instructions on the chart.
Assess a fuel solution
The interactive chart below gives a complete view of a chosen zero carbon fuel solution across TRL, IRL and CRL and all stages of the supply chain. Select a fuel by feedstock to view the ratings.
Focus on a specific area
The interactive table below provides all the results used in the charts. Choose TRL, IRL or CRL, fuel, feedstock and supply chain stage. Most fuels have just one form of onboard storage. Hydrogen fuel solutions include four forms of onboard storage technology.
The Tech type column applies only to hydrogen storage onboard ships. It reflects the four different hydrogen storage technologies under consideration.
