From a linear carbon economy to an integrated water–energy–carbon recycling economy

A CEWT position statement for governments, policymakers, financial institutions, industry and the scientific community

The fundamental industrial mistake

Carbon is indispensable to life, chemistry and modern industry. Carbon oxidation is also a useful chemical reaction: it supplies heat and supports essential industrial processes. The environmental problem is not the carbon atom or the act of oxidation itself. It is the continued extraction of geological carbon and the release of additional carbon dioxide into the atmosphere without effective recovery.

For generations, much of industry has followed a linear pathway: geological carbon → industrial use → CO₂ → atmosphere. This treats a valuable chemical element as a disposable resource. The result is cumulative atmospheric CO₂, alongside continued dependence on fossil resources.

Why fragmented decarbonisation is not enough

Having emitted CO₂ for decades, society is investing heavily in solar photovoltaics, wind power, electrification, renewable hydrogen, carbon capture, utilisation and storage (CCUS), and other climate solutions. These technologies can deliver substantial benefits. Renewable electricity can displace fossil generation, and permanent geological CO₂ storage can avoid atmospheric release. Yet deploying these technologies in isolation does not automatically redesign the industrial carbon cycle.

The question for policymakers and investors is not simply how much low-carbon electricity can be installed, but whether the whole industrial system is reducing new geological carbon inputs and lifecycle greenhouse gas emissions. Carbon capture without a viable use or durable storage pathway, hydrogen without appropriate integration, and electrification without attention to material supply chains can leave significant industrial emissions unresolved.

Fossil-fuel dependence can also contribute to geopolitical vulnerability and competition over resources. Climate change is increasing risks from heat, extreme rainfall and other hazards. These outcomes have multiple causes; nevertheless, continued greenhouse gas emissions remain a central driver of climate risk.

Electrification must include embodied emissions

Zero emissions at the point of electricity generation do not mean zero lifecycle emissions. Solar PV requires silicon, glass and aluminium; wind power requires steel, concrete and copper; batteries and electrolysers require mined and processed materials. Manufacturing, transport, construction and replacement all have carbon footprints.

This does not invalidate renewable energy. It reinforces the need to decarbonise the industries that manufacture renewable-energy infrastructure. Success should be measured through transparent lifecycle assessment, including embodied emissions, rather than operational emissions alone.

CEWT’s alternative: keep carbon in productive circulation

CEWT is developing Carbon Recycling Technology (CRT) around a different industrial principle: capture carbon dioxide from industrial operations, use low-emissions hydrogen to convert it into methane, and reuse that methane as an energy carrier or process feedstock. In simplified form: CO₂ + 4H₂ → CH₄ + 2H₂O. Subsequent methane use produces CO₂ that can be captured again.

The intended pathway is CO₂ → CH₄ → industrial use → CO₂ → CH₄. Renewable energy supplies the external energy needed to regenerate the fuel; carbon functions as a circulating material rather than a once-through geological resource. This is not a source of free energy. Its climate value depends on high CO₂ capture, low methane leakage, low-emissions hydrogen, and favourable full-system efficiency and lifecycle emissions.

Where direct electrification is more efficient and practical, it should be used. CRT is directed particularly at applications where carbon-containing fuels, reducing gases, continuous thermal supply or integrated process chemistry may remain valuable.

An integrated CEWT technology platform

CRT for power and industrial heat: CEWT proposes recycling captured CO₂ into methane for firm power, process heat and trigeneration, with recovery of useful thermal energy where practicable.

Green iron: hydrogen-rich reducing gases, CO₂ recovery and carbon recycling are being investigated to reduce the lifecycle emissions of ironmaking while maintaining reliable industrial operation.

Silicon production: CEWT is investigating methane-assisted/plasma-linked silica reduction with internal carbon recycling. The theoretical integrated net chemistry can be expressed as 2SiO₂ + 4H₂ → 2Si + 4H₂O. Carbon-containing intermediates may participate even if net carbon consumption cancels in the ideal stoichiometry. Experimental proof, actual yields, materials consumption and energy balances remain essential.

CAPZ desalination and DAC: CEWT proposes using sodium-rich ED concentrate, separated from calcium, magnesium, and sulfate through its NF/ED approach, as a starting medium for alkaline atmospheric CO₂ absorption. Part of the concentrate would feed caustic production through chlor-alkali electrolysis, with hydrogen and chlorine coproducts. The alkaline absorber would form carbonate/bicarbonate; BPMED-assisted pH adjustment and stripping would recover CO₂ and regenerate the working solution. The integrated DAC process remains subject to mass, ionic charge, water and energy balance validation.

Together, these developments aim to connect water treatment, industrial chemicals, carbon capture, fuel regeneration and materials production instead of treating them as unrelated projects.

What must be independently demonstrated?

CEWT welcomes independent engineering and scientific scrutiny. The proposed systems must be evaluated on a consistent basis: measured mass and energy balances; carbon capture and recycle rates; methane and process losses; electricity and hydrogen intensity; water use; equipment performance; costs; and cradle-to-grave lifecycle emissions.

Carbon utilisation is not equivalent to permanent carbon removal: methane made from captured atmospheric CO₂ will release that carbon again if combusted and not recaptured. A credible assessment must separately report avoided geological carbon use, avoided emissions, temporary carbon circulation and any genuinely durable removal.

Independent comparison should also include alternative pathways such as direct electrification, renewable generation, conventional CCUS and other industrial technologies. CEWT’s potential global contribution will depend on demonstrated performance, economic competitiveness and eventual deployment scale—not on aspiration alone.

A call to governments, financiers and industry

CEWT calls on governments, regulators, public agencies, financial institutions, manufacturers and research organisations to evaluate integrated carbon-recycling systems alongside established decarbonisation pathways. Funding and policy should reward verified system-wide emissions reductions, efficient resource use and replicable industrial outcomes—not only the installation of individual technologies.

We have spent decades developing technologies to manage the consequences of carbon emissions. It is time to redesign the industrial processes that created those emissions in the first place.

Carbon is not the enemy. The linear carbon economy is. Capture the carbon. Recycle the carbon. Reuse the carbon—and progressively end the need to extract new geological carbon for industrial use.
