Beyond Decarbonisation: Can We Defossilise Industry?

CLEAN ENERGY AND WATER TECHNOLOGIES PTY LTD (CEWT) Beyond Decarbonisation: Can We Defossilise Industry? LinkedIn Post — CEWT Carbon Recycling Technology (CRT) Platform The energy transition is usually framed around decarbonisation. At Clean Energy and Water Technologies (CEWT), we believe another question deserves attention: Can industry be defossilised without abandoning carbon as a useful process molecule? Carbon itself is not the problem. The problem is continually extracting new fossil carbon, using it once, converting it to CO₂ and releasing it to the atmosphere. CEWT's Carbon Recycling Technology (CRT) is being developed around a different principle: Use carbon → recover carbon → recycle carbon → reuse carbon. In the proposed CRT architecture, carbon-containing process streams are recovered rather than routinely discharged. Where appropriate, CO₂ is separated, reacted with hydrogen through methanation, and returned as methane to the industrial energy and process system. The objective is therefore not simply carbon capture. It is carbon recycling. One platform — multiple industrial pathways Power generation Oxy-combustion can produce an exhaust dominated by CO₂ and H₂O. Condense the water, recover the CO₂, convert it back to methane using hydrogen, and recycle the carbon-containing fuel. AI and data centres The challenge facing data centres is increasingly not merely access to renewable electricity, but access to reliable, continuous power at scale. CRT could potentially provide a firm-power platform complementing renewable generation, storage and grid supply. Cement Cement is particularly important because CO₂ comes from both fuel combustion and limestone calcination: CaCO₃ → CaO + CO₂. Instead of treating this process CO₂ only as a waste stream requiring disposal, CRT creates the possibility of treating recovered CO₂ as a carbon feedstock for recycling, subject to the required hydrogen and energy balance. Glass High-temperature glass furnaces present another potential application. Oxy-fuel operation can avoid much of the nitrogen dilution associated with air combustion, creating a more concentrated CO₂/H₂O exhaust stream suitable for downstream recovery and recycling. Aluminium Primary aluminium requires enormous quantities of continuous electricity. A CRT-based firm-power system could potentially complement renewable electricity and storage in supporting continuous smelter operation. The aluminium process itself presents additional carbon challenges that must be addressed separately. Caustic soda and chlor-alkali Chlor-alkali production is electricity intensive but also produces hydrogen as a coproduct. That hydrogen creates an especially interesting opportunity for integration with a carbon-recycling energy system. Solar-grade silicon and polysilicon The solar industry itself has an industrial-energy challenge. Production of metallurgical silicon and subsequent purification to solar-grade material involves high-temperature and energy-intensive processing. CRT could potentially contribute firm low-emission energy and carbon-management integration to this upstream solar-PV supply chain. From a technology to an industrial platform The individual process configuration will necessarily be different for every industry. CRT does not mean that one flowsheet can simply be copied from a steel plant into a cement kiln, aluminium smelter or silicon facility. Each application requires its own: mass balance → energy balance → carbon balance → hydrogen balance → oxygen balance → water balance → economics But the underlying philosophy remains the same: do not continually introduce new fossil carbon when the carbon already circulating within an industrial system can potentially be recovered and reused. That is what CEWT means by defossilisation. Extract → Burn/Process → Emit ↓ Use → Recover → Transform → Reuse Our current work on Green Iron + CRT baseload power is one application of this broader platform. The longer-term opportunity may extend across power generation, AI data centres, cement, glass, aluminium, chlor-alkali, desalination and the solar-PV manufacturing supply chain. Keep the carbon molecule working — without continually extracting another fossil carbon molecule from the ground.
