The Sun, sea and the wind are the energy sources in CEWT's Carbon recycling technology

CEWT Core Concept – Carbon Recycling Technology (CRT) The Sun provides the energy. The Wind expands the resource base. The Sea provides the resources. CRT closes the loop. Carbon Recycling Technology (CRT) is founded on a simple principle: work with Nature’s existing cycles rather than against them. CRT harnesses the Sun, the Wind, and the Sea as renewable sources of energy and resources. The Sun and Wind provide renewable electricity. The Sea provides water for hydrogen production and serves as a vast carbon reservoir through dissolved carbon dioxide. Seawater can also be used as a solvent to absorb and recover CO₂ emissions from industrial processes and power generation. In the CRT process: • Renewable energy from the Sun and Wind is used to produce hydrogen. • The Sea provides water for hydrogen production. • The Sea acts as a carbon reservoir through dissolved CO₂. • Seawater can be used to absorb and recover CO₂ emissions. • Captured carbon is recycled into renewable fuels and energy products rather than treated as waste. • Carbon remains within a circular system, reducing dependence on new fossil-carbon inputs. CRT transforms carbon from a waste stream into a recyclable carrier of renewable energy. Unlike conventional fossil-fuel systems, which transfer carbon from underground reservoirs to the atmosphere, CRT seeks to maintain carbon within a managed circular cycle powered by renewable energy. The result is a platform capable of producing: • Renewable Natural Gas (RNG) • e-Methanol • Sustainable Aviation Fuel (SAF) • e-Gasoline • Dispatchable Renewable Power • Industrial Decarbonisation Solutions CRT is not simply a fuel technology. It is a carbon-recycling platform that integrates energy, water, and carbon management into a single circular system. It also helps to stop ‘Ocean acidification’ simultaneously. The Sun provides the energy. The Wind expands the resource base. The Sea provides the resources. CRT closes the loop.

CEWT's Strategic road map using CRT Platform

CEWT Strategic Note: Integration of Low-Carbon Liquid Fuels into CRT Summary Carbon Recycling Technology (CRT) is fundamentally a carbon-recycling platform rather than a single-fuel technology. Its core principle is the combination of captured CO₂ and renewable hydrogen to create valuable products while maintaining a circular carbon economy. Current CRT Focus • Renewable Natural Gas (RNG) / Synthetic Methane • Dispatchable low-carbon power generation • Data-centre Trigen systems • Industrial decarbonisation and energy security Potential Low-Carbon Liquid Fuel Pathways 1. e-Methanol – produced from captured CO₂ and renewable hydrogen; suitable for shipping fuel and chemical feedstock. 2. Sustainable Aviation Fuel (SAF) – produced through downstream conversion pathways; supported by strong government incentives globally. 3. e-Gasoline – produced through methanol-to-gasoline pathways using existing liquid-fuel infrastructure. Strategic Implications for CEWT The CRT platform can be expanded beyond RNG to include a portfolio of renewable fuels. This supports CEWT’s evolution from a project developer into a technology licensor, systems integrator, and promoter of carbon recycling solutions. Future CEWT Product Portfolio • Renewable Natural Gas (RNG) • e-Methanol • Sustainable Aviation Fuel (SAF) • e-Gasoline • Dispatchable power and trigeneration systems • Industrial carbon recycling solutions Long-Term Vision CEWT can position itself as a Carbon Recycling and Renewable Fuels Platform Company. Rather than treating carbon as waste, CRT keeps carbon circulating within the economy by converting captured CO₂ into renewable fuels, energy, and industrial products. Recommended Near-Term Actions • Maintain primary focus on RNG and methanation projects. • Continue engagement with methanation licensors. • Explore e-Methanol, SAF, and e-Gasoline as future licensing and commercialisation pathways. • Incorporate low-carbon liquid fuels into CEWT’s technology roadmap and corporate profile.

Carbon Recycling Technology - the core concept in graphics.

Carbon Recycling Technology (CRT) Carbon Recycling Technology (CRT) creates a closed carbon loop. Natural gas is used to generate electricity in a gas turbine, and the resulting carbon dioxide (CO₂) is captured before it enters the atmosphere. Renewable hydrogen, produced using clean electricity, is then combined with the captured CO₂ to recreate methane (CH₄), the same fuel used by the turbine. In this process, the carbon atom is continuously recycled rather than released as waste. The energy comes from renewable hydrogen, while carbon acts as a reusable carrier moving around the loop again and again. CRT does not create free energy and does not rely on permanently storing CO₂ underground. Instead, it transforms CO₂ from a waste product into a valuable resource, enabling reliable power generation while greatly reducing dependence on new fossil fuels. In simple terms: Capture the CO₂ → Add renewable hydrogen → Recreate the fuel → Generate power again. Hydrogen provides the energy. Carbon provides the recyclable carrier.

CEWT's process to produce caustic soda/ Soda ash and derivatives directly from the seawater

CEWT Seawater-to-Chemicals Technology The global chlor-alkali industry depends heavily on high-purity crystalline salt produced from solar evaporation ponds. Modern caustic soda plants, with capacities ranging from several hundred to several thousand tonnes per day, require vast quantities of salt as feedstock for the production of caustic soda, chlorine, and hydrogen. However, increasing climate variability, erratic monsoon patterns, extreme rainfall events, and changing weather conditions are creating growing uncertainty in salt production regions. These disruptions can affect both salt availability and pricing, leading to higher production costs and supply-chain risks for chlor-alkali manufacturers. The impact extends far beyond the chemical sector. Industries dependent on caustic soda, chlorine, and related products—including aluminium refining, mineral processing, pulp and paper, detergents, glass manufacturing, water treatment, and numerous downstream chemical industries—are increasingly exposed to feedstock price volatility and supply uncertainty. CEWT’s proprietary seawater-processing technology offers an alternative pathway. Using a combination of Seawater Reverse Osmosis (SWRO), Electrodialysis (ED), and proprietary process integration, CEWT can directly produce valuable industrial chemicals from seawater, including: • Caustic Soda (NaOH) • Chlorine (Cl₂) • Hydrogen (H₂) • Sodium Carbonate (Na₂CO₃) • Sodium Bicarbonate (NaHCO₃) By reducing dependence on solar-evaporated salt production, the technology has the potential to provide a more stable and climate-resilient supply of critical industrial chemicals while leveraging one of the world’s most abundant natural resources: seawater. The approach offers potential benefits in: • Supply-chain resilience • Reduced dependence on salt harvesting • Improved feedstock security • Climate-change adaptation • Strategic industrial self-sufficiency • Integration with desalination and water-treatment infrastructure As global demand for industrial chemicals continues to grow, technologies that decouple production from increasingly vulnerable raw-material supply chains may become an important component of future industrial sustainability and resource security strategies. This framing is likely to resonate with chemical companies, aluminium refiners, investors, and government agencies because it focuses on resource security and climate resilience, which are becoming major strategic concerns.
