Long-term carbon removal and storage; nature and technology-based
Injecting carbon-rich liquids like bio-oil into deep geological formations permanently puts carbon back underground. Instead of agricultural waste biomass rotting or being digested and returning as CO₂ to the atmosphere, the carbon is injected deep into wells where it safely remains for thousands, or even millions of years. Long-lived carbon removal and storage is a new and emerging field, so we consult robust, third-party analyses by Carbon Plan as well as conduct our own expert review.
Storing high carbon content liquids deep underground is a very permanent form of carbon storage. Long-duration carbon removal and storage is going to play an increasingly important role in addressing climate change, and supporting innovation is crucial to catalyze investment in this space.
While the technology to create bio-oil and other high-carbon liquids is mature, injecting them into geologic storage comes with some practical risks. Supporting these early-stage projects will help innovators in the space prove out the process and gather the data needed to further scale the solution.
Partner: Charm Industrial
Carbon Portfolio Project: Yes
Charm uses waste biomass to create bio-oil through a process called “fast pyrolysis”. Bio-oil is conveniently high in carbon and a stable, pumpable fluid. Charm leverages EPA disposal wells to pump bio-oil and other high-carbon industrial byproducts deep underground, sequestering them for thousands of years. Your purchase helps Charm scale up their own bio-oil production and come down the cost curve.
Supply Chain Efficiency
This project has been reviewed by third party non-profit evaluator CarbonPlan. As well, this project has been heavily vetted and selected by competitive corporate negative emissions programs.
Charm Industrial provides an accessible ledger to customers to see when a purchase has been retired.
Charm Industrial’s business model relies exclusively on revenues from carbon removals, meaning that the biomass would rot or be digested by default and return carbon to the atmosphere unless the project is executed. Charm has also confirmed that the biomass it uses was not destined for fossil-fuel replacing activity. Removals purchased result in additional biomass conversion and ultimately injection underground that would not have otherwise occurred without our purchase.
Given the deep injection of biogenic carbon into the Earth, the duration of carbon storage is 1000+ years.
As an early-stage company, Charm Industrial has limited publicly available information on their website. However, a number of third parties have done a thorough independent review of their documentation, including Carbon Plan and large corporate buyers (e.g. Microsoft, Stripe, Shopify).
Supply Chain Efficiency
As Charm Industrial is the project owner, they receive 100% of the revenue from purchase.
“Engineered Sinks” as a climate solution is estimated to reduce/sequester between 2-4 gigatons of carbon between now and 2050. However, Project Drawdown has thus far assessed a limited set of solutions in this category and anticipates expanding their research moving forward.
Charm’s technology demonstrates a pathway for scaling up biomass technology and could lead to greater innovation in the carbon removal field. Charm Industrial’s overall method to inject biogenic carbon-containing liquids deep underground for carbon removal is patent-pending. While pyrolysis has been used for biochar production for many years, the use of pyrolysis to produce bio-oil for deep underground injection is novel.
Charm Industrial generates limited ecosystem benefits beyond long-term carbon sequestration. They commit to conducting an environmental review prior to building permanent conversion and injection plants in order to mitigate any environmental risks.
Charm Industrial’s solution addresses inclusive economic growth by employing workers in parts of the United States that are likely to be negatively economically impacted by the transition to a green economy.
