How CEWT’s Circular Carbon Recycling Technology (CRT)-Trigen Platform Delivers the Next Generation of Data Centre Infrastructure

How CEWT’s Circular Carbon Recycling Technology (CRT)-Trigen Platform Delivers the Next Generation of Data Centre Infrastructure Conventional data centre energy systems typically address power, cooling, and emissions as separate engineering challenges. CEWT’s Circular Carbon Recycling Technology (CRT)-Trigen platform integrates these functions into a single resilient energy architecture designed specifically for mission-critical facilities. The CRT-Trigen platform is designed to deliver the following simultaneously: 1. Continuous 24/7 Baseload Power • Reliable dispatchable electricity independent of intermittent renewable generation. • Simultaneous supply of both AC power for conventional equipment and DC power for next-generation AI and digital infrastructure through an integrated electrical architecture. • Behind-the-meter operation to improve resilience and reduce dependence on constrained transmission networks. 2. High-Efficiency Trigeneration • Recovery of waste heat from power generation. • Production of chilled water using absorption refrigeration instead of electrically driven chillers. • Combined utilisation of electricity, cooling, and thermal energy with an overall system efficiency approaching 95%, depending on operating conditions and heat utilisation. 3. Grid-Independent Operation • Designed to operate independently of the electricity grid when required. • Eliminates lengthy grid interconnection delays. • Provides enhanced energy security, power quality, and operational resilience for AI data centres and other critical infrastructure. 4. Circular Carbon Pathway • Captures carbon dioxide from power generation and recycles it using renewable hydrogen to produce Renewable Synthetic Natural Gas (RSNG). • Progressively replaces fossil-derived fuel with recycled renewable fuel through CEWT’s Circular Carbon Recycling Technology. • Provides a practical pathway towards near-zero operational CO₂ emissions and long-term defossilised operation. Rather than treating electricity, cooling, fuel, and carbon management as separate systems, CEWT’s CRT-Trigen integrates them into one modular energy platform engineered for the next generation of AI data centres and critical infrastructure.

Grid-Independent Trigen Plants for the Next Generation of Data Centres

Grid-Independent Trigen Plants for the Next Generation of Data Centres The AI revolution is driving unprecedented demand for reliable power, cooling, and sustainable infrastructure. Unfortunately, many data centre projects are now facing delays due to grid connection constraints, transmission bottlenecks, rising electricity costs, and increasing pressure to reduce emissions. What if a data centre could become largely independent of the grid? At Clean Energy and Water Technologies (CEWT), we are developing modular CRT-Trigen systems designed to provide: ✅ Reliable baseload power ✅ High-efficiency cooling for data centre operations ✅ Useful thermal energy recovery ✅ Carbon recycling and synthetic fuel production ✅ Reduced dependence on grid infrastructure Our modular approach is being developed in capacities of: • 20 MW • 50 MW • 100 MW • Up to 150 MW and beyond The system combines power generation, cooling, carbon capture, renewable hydrogen integration, and synthetic methane production within a circular carbon framework. Unlike conventional systems that continuously consume fossil carbon, the objective is to recycle carbon within a closed-loop process. Natural gas is primarily used during start-up and transition phases, with the longer-term goal of operating on recycled synthetic methane produced within the system itself. The result is a highly efficient Trigen platform capable of delivering electricity, cooling, and thermal energy from a single integrated facility while supporting the broader transition towards defossilisation. As AI, hyperscale computing, and digital infrastructure continue to expand, the future may belong not only to bigger data centres, but to smarter, more resilient, and more self-sufficient energy systems. The challenge is no longer simply generating electricity. The challenge is delivering power, cooling, and sustainability together. “The CRT-Trigen platform is designed to progressively reduce net carbon emissions through carbon capture and recycling, with the long-term objective of near-zero fossil carbon emissions.” “A conventional 20 MW gas-fired data centre energy plant emits approximately 41,000 tonnes of CO₂ per year. CEWT’s CRT-Trigen platform is designed to capture and recycle this carbon into renewable synthetic methane, creating a pathway toward a circular carbon energy system. #DataCentres #AI #EnergyTransition #Trigen #GridIndependence #Defossilisation #Hydrogen #CarbonCapture #CircularEconomy #Sustainability #CEWT

What is 'Defossilisation'?

1. Cement manufacturing – potentially circular In cement production, the CO₂ released from limestone calcination originates from: CaCO3=> CaO + CO2 . If that CO₂ is later reacted back into calcium carbonate (or permanently incorporated into concrete), the calcium-carbon system is effectively being cycled. Depending on the overall process and energy source, this can approach a closed mineral loop. Here, the carbon is not continually introduced from new fossil fuel extraction; it is being managed within an industrial materials cycle. 2. Diesel engine emissions – a different situation If CO₂ is simply captured from a diesel engine and permanently stored or mineralised, the system still depends on continuously extracting and burning new fossil diesel. The cycle is: • extract crude oil, • refine diesel, • burn diesel, • capture some CO₂, • repeat. The economic driver remains fossil fuel production. That is fundamentally different from our concept of defossilisation. 3. Diesel CO₂ + renewable H₂ → renewable fuel Suppose instead you capture the diesel exhaust CO₂ and combine it with renewable hydrogen: CO 2 + H2=> synthetic hydrocarbon The resulting renewable diesel (or eSAF, e-methanol, e-methane, etc.) can then displace fossil fuel. Now the carbon itself is recycled. Over time, the dependence on extracting additional fossil carbon can decline. This is much closer to our CRT philosophy because the carbon becomes a circulating resource rather than a waste product. The key distinction One point I would refine is this statement: “Capturing CO₂ from diesel encourages diesel production.” That is not necessarily true in every case. It depends on the system boundary. For example: • Capturing CO₂ from an existing diesel fleet while renewable fuel capacity is being built could reduce emissions during a transition. • Capturing CO₂ to manufacture renewable fuels could help replace fossil diesel over time. The important question is whether the process ultimately reduces reliance on continual fossil carbon extraction. A principle that aligns with my philosophy I can express it this way: Carbon capture should not become an enabler for perpetual fossil carbon extraction. Its highest value is achieved when captured carbon is progressively integrated into renewable circular carbon systems that reduce dependence on geological carbon. I think that’s a powerful statement because it doesn’t dismiss carbon capture or utilisation. Instead, it establishes a clear systems objective: the end goal is to replace the continuous flow of geological carbon with renewable and recyclable carbon, which is exactly the essence of my defossilisation concept.

CEWT CRT-Trigen Opportunity for AI Data Centres

CEWT CRT-Trigen Opportunity for AI Data Centres Executive Summary Artificial intelligence is driving unprecedented investment in hyperscale data centres. Developments such as the proposed A$10 billion AI data centre campus at the former Hazelwood Power Station site in Gippsland illustrate the growing need for reliable, low-emission, 24/7 energy. These facilities require continuous electricity, large-scale cooling, high resilience and a pathway to lower operational emissions. Conventional reliance on the grid, renewable generation and batteries alone may not satisfy all of these requirements economically as campuses scale into the hundreds of megawatts. The Opportunity CEWT's Carbon Recycling Technology (CRT)-Trigen system is designed as a system architecture rather than a standalone power-generation technology. It integrates power generation, carbon recycling, renewable synthetic methane production, cooling and heat recovery into a single modular platform capable of supporting critical infrastructure. CRT-Trigen Value Proposition • 24/7 dispatchable electricity for mission-critical operations. • Integrated trigeneration delivering electricity, chilled water for data centre cooling and useful thermal energy. • Closed-loop carbon recycling that converts captured CO₂ into renewable synthetic methane using hydrogen, reducing dependence on fossil fuels. • Modular deployment in 20 MW, 50 MW, 100 MW and 150 MW blocks, enabling phased expansion. • Reduced dependence on very large battery installations while improving resilience and energy security. • A practical pathway toward defossilisation and progressively lower operational emissions. Strategic Positioning CRT-Trigen is intended to complement, not replace, the electricity grid. It can operate behind the meter to improve reliability, reduce exposure to grid constraints, support peak demand and provide resilient energy for AI data centres, hospitals, campuses and other critical infrastructure. Why This Matters Now The rapid expansion of AI infrastructure in Australia and Asia is creating a significant market for integrated energy solutions. Rather than focusing solely on intermittent renewable generation or battery storage, CEWT offers a holistic energy architecture that combines generation, cooling, thermal recovery and circular carbon management. This differentiated approach aligns with the long-term requirements of hyperscale data centres seeking secure, efficient and sustainable operations. Potential Engagement Strategy CEWT could initially propose a 20 MW CRT-Trigen demonstration module for a future AI data centre campus, with the capability to expand in modular stages as demand grows. This phased approach reduces project risk while demonstrating commercial performance before larger deployments. Conclusion Global investment in AI data centres represents a major commercial opportunity for CEWT. By positioning CRT-Trigen as an enabling energy architecture for critical infrastructure, CEWT can address the industry's need for resilient, efficient and progressively defossilised energy systems. This positioning is expected to resonate with strategic investors, infrastructure developers and hyperscale data centre operators.
