CRT platform for Aluminium Decarbonisation.

Step-by-step platform logic (steel → aluminium → desal → chemicals) Step 1 — The shared constraint Baseload / firm power is the unlock. Steel, aluminium, desalination, and chemicals are continuous-process industries. They don’t just need energy; they need uninterrupted energy. If energy is intermittent, you either: • oversized storage (costly), or • curtail production (kills economics), or • fall back to fossil “insurance” (undermines decarbonisation). So the common logic is: Firm energy first. Everything else becomes possible. Step 2 — CRT’s role CRT functions as firm-energy infrastructure with embedded carbon control. That means CRT isn’t “a steel solution” or “an aluminium solution” — it’s the system that keeps an industrial site running without relying on fossil backup. Step 3 — Why aluminium + CAPZ + desal is a high-value cluster You’re right to highlight aluminium as the best “platform proof” because the value stack is naturally integrated: 1. Alumina/aluminium needs large, continuous electricity (electrolysis load). 2. It also needs caustic liquor (NaOH) in the Bayer process (upstream alumina refining). 3. A CAPZ-style precinct can co-locate: o firm power supply o caustic/soda chemistry loops (where applicable) o desalination to secure process water o shared utilities and carbon management infrastructure So the message becomes: In an aluminium precinct, CRT doesn’t just supply firm power — it supports the entire operating ecosystem (power + water + process chemistry), improving reliability and lowering system cost. Step 4 — Desalination and chemicals fit without stretching They fit because they share the same requirement: • 24/7 operation • high energy intensity • high penalty for interruption Desalination and chemicals are not “adjacent markets”; they are the same problem class: continuous industrial loads that require firm energy and stable utilities. Baseload power is the key that unlocks decarbonisation across multiple industrial sectors. Steel, aluminium, desalination and chemicals are continuous processes — they require uninterrupted energy, not just low-carbon energy. CRT is positioned as enabling infrastructure: it provides firm, dispatchable power with carbon control so industries can decarbonise without sacrificing throughput or relying on fossil backup. In aluminium precincts, the platform value increases further when combined with CAPZ and desalination, because aluminium and alumina operations are both power-intensive and dependent on stable process utilities (including caustic liquor and water). CEWT can address these as an integrated system rather than isolated technologies.
