The latest DAC insights

The Skytree Stratus architecture utilizes a moving-bed Temperature Vacuum Swing Adsorption (TVSA) process. By physically decoupling adsorption and desorption, this design solves the inherent thermal inefficiencies of traditional fixed bed DAC, offering a more stable and cost-efficient path to on-site CO₂ generation.

Capturing CO₂ is only the first step in the value chain. For industrial operators in sectors like food and beverage or e-fuels, the primary concern is the form and purity of the final product. Gas capture alone is often insufficient for sites that require CO₂ storage or specific food grade certifications.

Direct Air Capture (DAC) systems are, by definition, exposed to the elements. For an industrial-scale deployment, the local climate is a primary variable that dictates system reliability, machine capacity, and capture efficiency. A system designed for a laboratory will fail when faced with the abrasive sand of a desert, the corrosive humidity of the tropics, or the sub-zero reality of a polar winter.

From controlled-environment agriculture to e-fuel production, for industries requiring a reliable supply of CO₂, the primary barrier to adopting Direct Air Capture (DAC) has historically been energy cost. Traditional DAC systems have struggled with high energy consumption and rigid thermal requirements that made them difficult to integrate into existing industrial processes. Skytree Stratus rewrites this narrative by combining high-efficiency hardware, a unique moving-bed architecture, internal thermal harvesting, and utilization of external waste heat sources. 

Traditional Direct Air Capture (DAC) has long faced a fundamental atmospheric challenge: the weather. Because CO₂ capture relies on sensitive chemical reactions, a machine designed to work perfectly on a cool, humid morning in Northern Europe will inherently underperform during a dry, hot afternoon in the desert. These one-size-fits-all static systems result in wasted energy and under-utilized hardware.

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.

UK growers face a complex set of challenges from weaknesses in their two most critical inputs: energy and CO₂. Together, these challenges threaten grower profitability and operational stability.

Most CO₂ used in greenhouses today comes from:

Prime Minister Mark Carney, sworn in on March 14, 2025, entered office promising to swap “sticks” for “carrots” in federal climate policy. Since then, his government has scrapped two high-profile taxes and introduced a package of new incentives. If these are passed in this fall’s Budget 2025, Canada could take a global lead in carbon dioxide removal (CDR) policy.

The Net Zero Act is a crucial law that is a part of the Green Deal Industrial Plan and was approved by the EU Parliament this year. It aims to reach climate neutrality by cutting greenhouse gas emissions to net zero by a target year, often 2050.

Carbon dioxide (CO₂) has a marketing problem. Everyone knows we have too much of it in the atmosphere but it also has a number of uses in everyday society. Currently the US Southeast is readying to cope with or already in the throes of an acute CO₂ shortage, exacerbated by the temporary shutdown of a plant critical to the CO₂ supply in the region. The Hopewell plant in Virginia is scheduled to undergo maintenance from late September, potentially causing a massive impact on CO₂ supply for up to eight weeks.

Driven in large part by a string of significant news headlines, enthusiasm for Direct Air Capture technology has seemingly exploded in just the past few months.
