Readiness Levels.
Interactive tools to show how promising future fuel solutions compare on the readiness scale.
Compare fuel solutions
The interactive charts for TRL, IRL and CRL show how promising zero carbon fuel solutions compare on the readiness scales. Select a stage of the supply chain or view the average across all stages of the supply chain.
Assess a fuel solution
The interactive chart gives a complete view of a chosen future fuel solution across TRL, IRL and CRL and all stages of the supply chain. Select a fuel by feedstock to proceed.
Drill down to the details
The interactive table 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.
TRL is measured on a scale of 0 to 9, whilst CRL and IRL are measured on a scale of 0 to 6. To make comparisons easier, the table includes a normalised figure, measured all indicators on a percentage basis.
The Tech type column applies only to hydrogen storage onboard ships. It reflects the four different hydrogen storage technologies under consideration.
