The early era of Direct Air Capture (DAC) was defined by bespoke, site-specific engineering. While these one-off projects were vital for technical validation, they represent a significant commercial bottleneck. Custom designs demand excessive engineering hours, unique operating procedures, and high-risk integration. To meet the global demand for CO₂, the industry must transition from building individual plants to deploying standardized, configurable modular systems.
Skytree Stratus is designed to break this bottleneck by moving away from bespoke sites toward a serialized, modular architecture.
Skytree Stratus is not a monolithic product with a set capacity; it is a synchronized ecosystem of specialized modules. This functional decoupling allows us to treat each area of the capture process as a standardized building block that can be manufactured at scale:
Adsorbers: The lungs of the system, housing thin, moving sorbent beds that capture CO₂ from ambient air.
Desorbers: High-precision vacuum environments where the sorbent is heated to release captured CO₂ and associated water vapor.
Gas processing: A recovery stage that separates water from the gas stream, resulting in a high-purity CO₂ product.
Thermal management: The utility heart that provides the necessary heating and cooling liquids across the entire setup.
Auxiliary systems: Units that handle the brain functions: process control, electricals, and water treatment with optional add-ons for storage or liquefaction.
The power of the Skytree Stratus architecture lies in the shift from construction to configuration. Because these modules are standardized and mass-produced with best-in-class manufacturing partners, we can drive down the Total Cost of Ownership (TCO) through economies of scale.
Additionally, a system is not a fixed size. Depending on a project’s specific CO₂ requirements and available energy, we deploy the optimal configuration of adsorption, desorption, gas processing and thermal management systems. This modular scaling principle allows for a right-sized deployment, ensuring that operators aren't paying for an oversized plant or struggling with an underpowered one. This flexibility also hints at the system's inherent climate adaptability, allowing the hardware to be tuned to the specific humidity and temperature profiles of different regions.
This modular approach creates a new paradigm for growth: Skytree Stratus Park. We scale in two distinct layers:
System configuration: An operator can define an initial configuration to hit a specific goal, for example, a setup targeting 5,000 tonnes of CO₂ per year. This allows for a precise entry point that aligns hardware with immediate demand.
The park architecture: To achieve megaton-scale, site capacity is increased by networking multiple modules and configurations to shared utility infrastructure.
This parks, not plants philosophy enables endless scalability. If you need more capacity next year, you simply add more modules or configurations. This enables phased deployment, helping developers manage cash flow and align capital allocation with the actual growth of their CO₂ utilization or storage projects.
Modularity de-risks development. In a monolithic plant, a single valve failure can lead to a total site shutdown. With Skytree Stratus Park, individual modules can be isolated for maintenance or sorbent swaps without impacting the rest of the facility. This distributed capacity ensures a continuous, reliable CO₂ supply.
Furthermore, the modular nature offers unique operational flexibility. Production can be ramped up or down at the modular level to shift power consumption to periods of lower energy costs or to align with the intermittent nature of renewable energy sources. By moving the technical complexity into the factory through serial production and enabling granular, site-wide growth, Skytree is transforming DAC from a bespoke engineering challenge into a reliable, scalable, and industrial-grade utility.
