The answer, in three positions

The frontier

Electrochemical CO₂/CO

Fund43.6%/yrTRL 5

The fastest-improving route in the set, more than twice any classical route, and already out of the laboratory. It drew 239 new organisations in 2020 or later — more than the rest of the field combined. The only route in the fund quadrant: mature enough to be real, and still compounding fastest.

The standard

Classical cracking, in all its forms

Phase out13.0–19.8%/yr

Conventional cracking improves at 13.0%/yr, catalytic at 15.4%, electrified at 19.8%. All sit in the phase-out quadrant: established, and improving more slowly than the routes coming for them. Electrifying the furnace changes the heat source, not the improvement trajectory.

The asset question

A new cracker of any kind

30–50 yr assetSanctioning decision

A new classical cracker needs decades to depreciate. On these rates, the new routes take over well inside that window. That is the judgement a sanctioning decision now has to survive — and nothing in a stage-gate review surfaces it.

Findings

Five conclusions for the next portfolio review.

13.0%

Last of fourteen

The technology the industry runs on is the slowest-improving route in its own competitive set. Not failing — operating near its thermodynamic limits, which is what maturity looks like. It cannot compound its way out of a carbon constraint.

35.0%

vs 15.7% incumbent

The fastest compounding is happening in a different discipline from the one most producers own. The CO₂ routes advance on electrochemistry and CO₂ handling — a different skill base, hiring pool and partner set from steam-cracking process engineering. Capability, not capital, is the binding constraint.

20.9%

Ceiling on deployable routes

Everything ready to build today improves more slowly than everything that is not. Every route above 23%/yr sits at TRL 4–6. Stage-gating on readiness concentrates capital in the slower half of the domain — and nobody reviews that as a strategy, because it is a consequence of the gate, not a decision.

7 of 14

Routes led by one competitor

Capability is consolidating faster than the technology is. One organisation is the apparent technical leader in half the routes; Chinese organisations lead nine of fourteen. Breadth across every carbon strategy does not require predicting the winner — only being present when one emerges.

1.9 yr

Frontier doubling time

The frontier improves roughly three times faster than a planning cycle can see. The fastest route doubles every 1.9 years against the incumbent's 5.7. A five-year plan spans about 2.6 doublings of the frontier — any slower review rhythm discovers inflections after they have happened.

What this decides — and what it leaves to you. These are current positions on external technology evidence, not capital commitments. Plant economics, power price, feedstock cost, policy and asset fit are separate filters — and they belong to you.

The system

Ethylene is the example. The system is the product.

The capability behind this report runs continuously across an entire R&D portfolio: a baseline of where every contested route stands, living radars that keep positions current, and trigger alerts when a defined signal fires. First radar in weeks · monthly movement summaries · quarterly executive review.

Where in your next portfolio review are several technical routes competing for capital — without a shared external trajectory, or an agreed trigger for action?
