Two stage CRT (Carbon Recycling Technology(

1. Design Principle: Two-Unit CRT Architecture In order to ensure that carbon accounting is auditable, accountable, and easily measurable, CEWT has deliberately structured Carbon Recycling Technology (CRT) into two distinct but connected operational units, rather than treating it as a single aggregated power cycle. This design decision was taken to: • establish clear system boundaries; • enable continuous and independent measurement of carbon flows; and • eliminate ambiguity in emissions attribution. This approach aligns directly with the objectives of the Guarantee of Origin (GO) framework, which prioritises transparency, traceability, and measured outcomes. 2. Fuel Generation Unit (FGU) The Fuel Generation Unit (FGU) is responsible for: • receiving captured CO₂ (measured input); • receiving renewable hydrogen (GO-verifiable input); • converting these inputs into a methane-based energy carrier via methanation. The output of the FGU is Recycled Synthetic Methane Gas (RSMG), which remains within CRT system custody and is not exported or supplied to third parties. 3. Power Generation Unit (PGU) The Power Generation Unit (PGU): • uses RSMG as fuel in a gas turbine combined cycle; • generates electricity; • captures the resulting CO₂ exhaust; and • returns the captured CO₂ back to the Fuel Generation Unit. During steady-state operation, no carbon is released to the atmosphere. 4. Carbon Looping and Auditability By separating the system into two auditable units and connecting them via a closed carbon loop, CRT ensures that every carbon atom is measured on entry, tracked during conversion, measured during combustion, and recycled back into fuel production. There is no Scope-3 exposure, no reliance on offsets, and no dependence on third-party behaviour. Carbon transparency is therefore achieved by system design rather than post-hoc reporting. 5. Terminology Clarification: RSMG vs e-Methane The term “e-methane” is commonly used to describe power-to-gas fuels produced for market export and third-party combustion. This description does not apply to CRT. In CRT: • methane is not exported; • methane is not sold as a fuel product; • methane is not combusted outside system boundaries. The correct term is therefore Recycled Synthetic Methane Gas (RSMG), accurately reflecting that the methane is produced from recycled carbon and renewable hydrogen and functions solely as an internal energy carrier. 6. Product GO Alignment (RSMG) RSMG is assessed only as an internal energy carrier, not as a traded fuel. Key characteristics: • produced from renewable hydrogen and captured CO₂; • carbon remains within system custody; • continuous measurement and reconciliation. Accordingly, RSMG may be recognised as a renewable, carbon-neutral fuel within a closed system for Product GO purposes. 7. Renewable Electricity GO Alignment Electricity generated in the Power Generation Unit: • is derived from RSMG produced using renewable hydrogen; • operates with continuous carbon capture and recycling; • results in zero net atmospheric CO₂ emissions during steady-state operation. Accordingly, electricity generated under CRT qualifies as renewable, carbon-neutral, zero-emission baseload electricity under the Renewable Electricity GO framework. 8. Definitions Carbon Recycling Technology (CRT): A closed-loop system that captures CO₂, converts it using renewable hydrogen into RSMG, and continuously recycles carbon while generating firm electricity. Fuel Generation Unit (FGU): Subsystem responsible for renewable hydrogen input, captured CO₂ input, and RSMG production. Power Generation Unit (PGU): Subsystem responsible for electricity generation and CO₂ capture for return to the FGU. Recycled Synthetic Methane Gas (RSMG): Methane produced from captured CO₂ and renewable hydrogen, used exclusively as an internal energy carrier within CRT. 10. Concluding Statement CRT has been intentionally structured to allow Product GO and Renewable Electricity GO assessments to be conducted on clearly defined subsystems, linked by a measurable carbon loop. This architecture avoids ambiguity, simplifies verification, and supports robust, outcome-based certification under the GO framework.

Clean Energy and Water Technologies Pty Ltd (CEWT) Carbon‑Negative Fuel Supply with CO₂ Buy‑Back Loop Bank‑Ready One‑Page Project Explanation 1. Project Overview This model separates power generation and carbon recycling into two contractually linked but independently bankable assets. CEWT supplies renewable methane as a fuel to a conventional 135 MW gas power plant, and contractually buys back the resulting CO₂ for conversion back into methane, closing the carbon loop. 2. Physical and Commercial Flow Renewable electricity is used by CEWT to generate hydrogen via electrolysis. Captured CO₂ is combined with hydrogen through methanation to produce renewable methane. This methane is sold under a long‑term fuel supply agreement to a 135 MW gas power plant. The power plant generates dispatchable electricity and produces CO₂, which is captured and transferred back to CEWT under a CO₂ buy‑back agreement. The CO₂ is recycled into further methane production. 3. What Is Being Sold Renewable methane as a physical fuel commodity. Dispatchable baseload electricity to the grid or industrial offtakers. CO₂ as a recyclable feedstock rather than a liability. 4. Carbon and Emissions Treatment The gas power plant operates in a conventional manner but with renewable methane as its fuel. All CO₂ generated is measured, captured, and contractually transferred back to CEWT for recycling. Net system emissions are zero to carbon‑negative, achieved through physical carbon recycling rather than offsets or credits. 5. Bankability and Risk Allocation This structure aligns with established infrastructure financing logic. Fuel supply agreements, power purchase agreements, and CO₂ handling contracts are familiar to lenders. The model avoids dependence on carbon credits or policy incentives. Technology risk is ring‑fenced within the CEWT carbon recycling entity, while power market risk remains with the generator. 6. Key Bank Takeaway “This is a conventional gas power project supplied with a renewable fuel, where carbon is continuously recycled rather than emitted. The business case relies on long‑term energy contracts and physical carbon management, not carbon credits.”
