Hamed Sanei

Professor Dr Hamed Sanei is a globally renowned, Canadian geoscientist, in organic petrology and geochemistry whose career spans decades of groundbreaking discovery across the geosphere, from the highest reaches of the Arctic to the deepest ocean trenches and now to the forefront of the global climate transition. Currently a Professor at Aarhus University and Director of the Lithospheric Organic Carbon (LOC) Laboratory, he previously served as a Senior Research Scientist at the Geological Survey of Canada, where he spearheaded the Unconventional Reservoir Characterization project. His research legacy is remarkably diverse, perhaps most famously marked by his identification of mercury (Hg) anomalies as diagnostic markers for volcanic-induced mass extinctions. His work was the first to identify a massive "mercury spike" at the Permian-Triassic boundary—the "Great Dying"—linking the largest extinction event in history to the catastrophic volcanic activity of the Siberian Traps. Geologists worldwide have since extended this "mercury fingerprint" across the geological record, proving that mercury loading was a consistent factor in major extinction crises.

Professor Sanei’s exploration of the planet’s "inner space" led to the pioneering measurements of mercury fluxes in hadal trenches like the Atacama, Kermadec, and Aleutian. His research revealed these extreme depths as critical, previously overlooked global sinks for mercury and organic carbon, demonstrating how the "biological pump" transports toxic metals to the deepest parts of our ocean. In the Canadian High Arctic, his work redefined environmental science by proving that aquatic primary productivity, rather than just atmospheric deposition, controls mercury accumulation in aquatic sediments. In the realm of energy geoscience, he developed the definitive "Five-Stage Bitumen Model," which remains the global cornerstone for understanding reservoir quality in tight gas siltstone plays like the Montney Formation, while also uncovering how radioactive radiation within black shales degrades organic molecular structures over millions of years.

Building on this profound understanding of the Earth’s natural organic carbon cycle, Professor Sanei has recently pivoted to engineering the climate solutions of the future through his pioneering work in biochar and carbon dioxide removal (CDR). He is the architect of the Inertinite Benchmark (IBRo2%), a novel scientific standard that provides the biochar industry with geologically-based proof of permanence. By demonstrating that biochar is a synthetic version of inertinite—the most stable form of organic carbon in the sedimentry rocks—he corrected long-standing modeling inaccuracies and proved that biochar can resist degradation for millions of years. This scientific breakthrough is the foundation of his work as a co-founder of Fusinite Ltd., the world’s first dedicated digital portal for verification of the long-term sequestration value of biochar. He also co-founded Sunstones ApS (sunstones.dk), a venture at the cutting edge of carbon mineralization and the utilization of geological materials to mimic the Earth’s natural "organic carbon pathway."

Throughout his career, Professor Sanei has held significant leadership roles in major international associations, serving as the President of The Society for Organic Petrology (TSOP) and the Canadian Society of Organic Petrology (CSCOP). Today, he bridges the gap between pure science and industrial application as a technical advisor to Biochar Europe and AxessImpact, ensuring that international climate policy and carbon crediting frameworks are underpinned by rigorous geological science. His work continues to redefine how humanity interacts with the global carbon cycle, transforming ancient geological insights into modern tools for a net-zero future.
