en.Wedoany.com Reported - Carbon removal company UNDO, in collaboration with researchers from Newcastle University and The James Hutton Institute, has co-authored a paper on enhanced rock weathering measurement techniques. Published by Cambridge University Press, the paper primarily explores UNDO's patent-pending SATuration-Centrifugation (SAT-C) method, which can support the scalable application of enhanced weathering across different climates, seasons, and soil types.
Enhanced weathering is a nature-based technology that spreads crushed silicate rock on farmland to absorb carbon dioxide, long regarded as a promising pathway for carbon removal. However, traditional methods for measuring carbon removal rely on natural soil moisture to extract pore water, limiting data collection during dry periods and creating gaps in long-term monitoring. As global drought conditions become increasingly frequent, year-round measurement has become a critical need.
UNDO's SAT-C technology recovers pore water from soil for chemical analysis by combining intact soil core sampling, controlled saturation with deionized water, and centrifugal separation. This technique enables reliable pore water samples regardless of soil moisture levels, generating continuous monitoring, reporting, and verification (MRV) data across different climates and seasons, thereby enhancing carbon credit quality and underwriting confidence.
Validation of SAT-C has been conducted at scale in UNDO's Canadian field trials, with supporting results scheduled to be presented at the Goldschmidt Conference in Montreal in July 2026. This research also collaborates with McLaren Racing's Accelerator programme, where an engineering team leverages motorsport engineering and F1 technology to prototype a SAT-C soil auger suitable for year-round deployment. This battery-powered auger can reach depths of up to 30 centimeters throughout the year, operating reliably in dry, compacted soils as well as wet winter conditions, while preserving soil structure and minimizing land impact. The latest prototype reduces soil sampling time by 70% and associated emissions by 90%, improving deployment reliability and ease of use.
Kim Wilson, Director of Sustainability at McLaren Racing, stated that the team is committed to achieving net-zero emissions by 2040, and through collaboration with UNDO, demonstrates the application of high-performance engineering to address environmental challenges, accelerating the pace of climate solutions. UNDO Founder and CEO Jim Mann noted that SAT-C is a key breakthrough in enhancing the credibility and economic viability of enhanced weathering, removing one of the major barriers to scaling permanent carbon removal globally.
Although SAT-C was developed in the context of enhanced weathering, the soil monitoring challenges it addresses also exist in fields such as agriculture, land restoration, and environmental remediation, giving the technology's scientific value broader applicability. The technology offers a pathway to reduce verification costs and expands the range of viable enhanced weathering projects globally, with each carbon credit generated using this technology supported by a real-time, traceable audit trail.
