CSI is pioneering carbon removal and storage using innovative, specially engineered underground clay vaults in East Texas to permanently trap and store woody biomass.
We Lead the Way
Terrestrial Storage of Biomass (TSB) is a long-term, all-natural storage solution that moves carbon within wood out of the fast cycle, where it would decay in months or years, and places it into the slow cycle, mimicking the conditions where coal is naturally created.
Located in East Texas, we transport unwanted biomass to our underground storage vaults, designed to eliminate air and liquid transfer between the wood vault and the atmosphere. Here, carbon is durably and indefinitely stored for over 1,000 years.
Using waste biomass (agricultural, forest, trash and food waste) is vital to achieving our national carbon goals. Suitable geologic storage is available in many parts of the country, and storage capacity is much greater than any potential sequestration demand. Establishing the existence or lack thereof of viable storage in parts of the country with sparse data will require experience in the field, and the learning that comes with it.
Environmental justice is a major constraint on CDR—a large-scale endeavor that will touch so much of our land, population, and economy. At this point it is too early to say what changes and limitations must be placed on CDR approaches in order to improve the lives of all Americans, but it is clear that it will be possible to find all natural, green solutions which provide environmental, socioeconomic and economic co-benefits to the communities and our Nation.
Leaders in the innovation of clean, natural carbon removal methods.
Our Mission is Simple: Create the best, cleanest and most economic solution to trapping and burying the carbon stored within biomass while keeping the land safe for plants and wildlife!
Working with the Community and the Environment
Headquartered in Houston, Texas, our projects are located in the southeast portion of the Lone Star State.
We are close to the field, but also at the epicenter of commerce and trade, making us ideal to partner with anyone anywhere in the world.
Forests are actively managed and a fraction is selectively harvested via collection of dead wood, timber slash, or cutting of non-commercial trees.
In Terrestrial Storage of Biomass, wood residues are buried in engineered sub-surface pits, creating anaerobic conditions that significantly slow wood decomposition and substantially limit the production and migration of methane and CO2.
Our long-term storage method, Terrestrial Storage of Biomass (TSB), moves carbon within wood into the slow decay cycle.
The biomass is stored in underground vaults, sequestering it by eliminating above-ground decomposition or burning of forest residues. This process removes oxygen and water contact from above, and beneath, the sealed carbon chamber, resulting in biomass being stably stored for over a millennium!
Co-benefits include:
Cleaner air in rural communities where the wood would have been burned
Increased oxygen levels
Improved air quality
Employment opportunities in rural communities
Improved access to forested areas
Improved drainage in flood-prone areas
Utilization of waste products
Opportunities to create long-term forested habitats
