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.

Defossilisation: A Holistic Process Engineering Framework for Future Energy Architecture

Defossilisation: A Holistic Process Engineering Framework for Future Energy Architecture By Ahilan Raman Managing Director, Clean Energy and Water Technologies Pty Ltd (CEWT) Introduction For over two centuries, industrial civilisation has been powered by fossil fuels. This remarkable achievement has transformed human society, increasing life expectancy, productivity and prosperity. However, it has also transferred vast quantities of carbon from long-term geological storage into the Earth’s active carbon cycle, leading to the accumulation of greenhouse gases and the climate challenges we face today. The challenge before us is therefore not to abandon industrial progress, but to redesign the way energy systems are conceived and operated. This requires a new engineering philosophy. Defining Defossilisation Defossilisation is the progressive elimination of society’s dependence on geological carbon while maintaining sustainable economic development, energy security and human well-being. Unlike decarbonisation, which often focuses on reducing carbon emissions, defossilisation addresses the root cause of climate change—the continuous extraction and combustion of fossil carbon. Carbon itself is not the enemy. Carbon is the fundamental building block of life. The challenge is the continual transfer of carbon from geological reservoirs into the atmosphere without closing the carbon cycle. The objective of defossilisation is therefore to restore balance by progressively replacing fossil carbon with renewable carbon, recycled carbon and other sustainable energy pathways. Holistic Process Engineering Future energy systems cannot be optimised by improving individual technologies in isolation. Instead, they must be designed using Holistic Process Engineering (HPE), where every component is evaluated as part of an integrated system. HPE simultaneously optimises: • Carbon balance • Mass balance • Energy balance • Water balance • Heat integration • Exergy efficiency • Environmental performance • Economics • Reliability and resilience This systems approach enables significantly greater overall performance than isolated optimisation of individual processes. Future Energy Architecture Future Energy Architecture should integrate multiple complementary technologies rather than relying on a single solution. These may include: • Renewable electricity • Sustainable hydrogen • Circular carbon recycling • Carbon capture, utilisation and storage • Sustainable fuels • Thermal energy recovery • Water treatment and reuse • Energy storage • Digital optimisation and artificial intelligence The optimum combination will differ between regions and industries, but the guiding principle remains the same: progressively eliminate dependence on geological carbon while delivering reliable, affordable and secure energy. Engineering for Civilisation Industrial development and climate responsibility are not opposing objectives. Modern society requires reliable electricity, transport, manufacturing, clean water, food production, healthcare, communications and digital infrastructure. These essential services must continue to expand as the global population grows. Defossilisation provides a pathway to achieve this by redesigning energy systems rather than restricting economic development. The Path Forward The future will not be built by one technology alone. It will be built through integrated engineering solutions that combine the best available technologies into resilient, efficient and economically sustainable systems. Defossilisation is therefore more than an environmental objective. It is a new engineering framework for designing the energy systems of the twenty-first century. By applying Holistic Process Engineering, society can continue to prosper while progressively restoring the Earth’s natural carbon balance. The future of energy is not simply renewable. It is defossilised.

Holistic Process Engineering and Defossilisation: The Foundation of Carbon Recycling Technology (CRT)

Holistic Process Engineering and Defossilisation: The Foundation of Carbon Recycling Technology (CRT) Holistic Process Engineering (HPE) Holistic Process Engineering (HPE) is an engineering philosophy inspired by Nature’s integrated processes. It recognises that enduring natural systems are sustained through dynamic equilibrium, where matter, energy, and information continuously flow in balanced relationships. Nature does not optimise isolated functions. Instead, it integrates multiple functions into coherent, self-sustaining systems. Photosynthesis is an outstanding example. A single biological process simultaneously captures solar energy, utilises carbon dioxide, releases oxygen, synthesises carbohydrates, stores chemical energy, and supports life. Sustainability is therefore not an external objective—it is an intrinsic property of the process itself. Holistic Process Engineering seeks to learn from this systems architecture. Rather than optimising individual unit operations in isolation, HPE designs industrial processes as integrated systems that operate in harmony with the dynamic equilibrium of the larger natural systems upon which they depend. Accordingly, sustainability is not treated as an additional design constraint or regulatory requirement. It is an inherent outcome of the process architecture. Defossilisation Defossilisation is a practical application of Holistic Process Engineering to the industrial carbon cycle. Over geological time, Nature transferred carbon from the active biosphere into fossil reservoirs. Human industrialisation rapidly reversed this process by extracting and oxidising fossil carbon within only a few centuries. This created an imbalance between the rate of carbon extraction and the rate at which natural systems recycle carbon. Defossilisation seeks to eliminate dependence on geological fossil carbon by maintaining carbon within a continuously recyclable industrial loop powered by renewable energy. Rather than treating carbon dioxide as waste, it is regarded as a valuable carbon feedstock that can be repeatedly recycled. The objective is therefore not simply to reduce emissions, but to restore a dynamic equilibrium between industrial activity and the natural carbon cycle. Carbon Recycling Technology (CRT) Carbon Recycling Technology (CRT) is the first practical embodiment of the principles of Holistic Process Engineering and Defossilisation. CRT captures carbon dioxide, combines it with renewable hydrogen to produce renewable synthetic methane, generates electricity, heat and cooling, and continuously recycles the resulting carbon dioxide back into the process. Carbon remains in a closed industrial cycle while renewable energy provides the energy input required to sustain the system. Unlike conventional fossil-fuel systems, which transfer carbon irreversibly from geological storage to the atmosphere, CRT is designed to maintain carbon within a circular industrial pathway. CRT therefore, represents more than a new energy technology. It demonstrates how industrial systems can be designed according to the principles of Holistic Process Engineering, where sustainability is an intrinsic property of the process rather than an external requirement. In this framework: Dynamic Equilibrium → Governing Principle Holistic Process Engineering → Engineering Philosophy Defossilisation → Carbon System Objective Carbon Recycling Technology (CRT) → Practical Industrial Implementation This progression provides a unified conceptual framework for developing future industrial systems that are technically robust, economically viable, and inherently sustainable.

20MW CEWT's CRT based Trigen for Data centre

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. #DataCentres #AI #EnergyTransition #Trigen #GridIndependence #Defossilisation #Hydrogen #CarbonCapture #CircularEconomy #Sustainability #CEWT
