Enhanced Weathering

Enhanced Rock Weathering - Everest Carbon Aeon 1 - India

Everest Carbon applies natural minerals to agricultural soils in India for irreversible, directly measurable, and verifiable removal of atmospheric CO2 via Enhanced Weathering.

Everest Carbon is a US-based technology company developing and operating innovative Enhanced Rock Weathering projects in India. The company uses Wollastonite, a natural mineral that weathers particularly fast, and their methodology is based on the academic work and field trials of their scientific advisor, Prof. Rafael Santos, who is a leading scholar on Enhanced Rock Weathering with Wollastonite worldwide. Notably, Prof. Santos also advised on the development of the Puro Earth Enhanced Rock Weathering methodology. Wollastonite weathers orders of magnitude faster than typical weathering materials, which puts Everest Carbon in the unique position of being able to directly measure their highly durable and irreversible carbon removals in the form of additional solid inorganic carbon content in their soil samples. The Wollastonite is sourced from local mines in the districts of Ajmer and Udaipur in Rajasthan where each ton of Wollastonite leads to 449.5kg of CO~2~e gross removals, including a 19% uncertainty discount to conservatively account for any potential leakage and uncertainty. Due to the close proximity of their fields, cradle-to-grave project emissions are only 59.74kg of CO~2~e per ton of Wollastonite or 13.3% of gross removals. Beyond high-quality carbon removals, Everest Carbon sets itself apart by combining its Enhanced Rock Weathering projects with Nature Restoration projects in rural areas of India. To do so, the company collaborates with local communities, thereby delivering socio-environmental co-benefits that truly stand out. Last but not least, India has highly advantageous geo-climatic conditions that make it ideal for Enhanced Rock Weathering. Everest Carbon's mission is to reduce the cost of Enhanced Rock Weathering to below $100/t well before 2030 and scale up to a capacity of 1 billion tons of annual carbon removal before 2035, thereby providing a critical piece of technology to humanity's fight against climate change. **How it works** Enhanced Rock Weathering is the acceleration of the Earth’s natural carbon cycle. Enhanced Rock Weathering removes CO2 from the atmosphere by crushing and grinding natural alkaline silicate rocks, like Wollastonite, to fine powders and spreading them in soils. The small particle size and large contact area with the atmosphere will then increase the effective weathering rate by multiple orders of magnitude, therefore enhancing the natural weathering process.The rock's silicate dissolves upon contact with water, releasing base cations (e.g. Ca2+) that convert atmospheric CO2 into dissolved inorganic carbon in the form of liquid bicarbonates or solid carbonate precipitation. Land surface runoff will then transport the stored carbon to the ocean where it is safely stored for tens of thousands to hundreds of thousands of years. The methodology is possible to be replicated in many new locations and the company aims to scale quickly across India. The carbon removal purchases help them accelerate their capacity scale-up, which will bring down costs through economies of scale and learning effects, all the while directly restoring nature and biodiversity on the lands they operate on.
