Carbon Removal Startup BluSky Becomes Public, Aims To Scale Innovative Pyrolysis + DAC System - Carbon Herald

A new carbon removal startup announced on June 20th it has become a publicly traded company. BluSky Carbon Inc. – an innovative carbon removal solutions provider, was welcomed on The Canadian Securities Exchange on June 20 where it began trading under the symbol BSKY. 

The company issued an aggregate of 11,500,000 units, including exercise in full of the over-allotment option, at a price of $0.50 per unit, and raised a total gross proceeds of $5,750,000. Each unit consists of one common share and one-half of one share purchase warrant. Each whole warrant entitles the holder to purchase one share for an exercise price of $0.75 until June 19, 2026.

The purpose of the public offering is for the company to expand facilities, its marketing, research and development, and for general and administrative purposes.

“We are thrilled to join the Canadian Securities Exchange… The BluSky team is working diligently to help solve the great climate challenge of our time. This is a tremendous day for both BluSky and for climate technology everywhere. We hugely appreciate the Canadian Securities Exchange for its warm welcome,” commented William Hessert, BluSky Carbon’s CEO.

BluSky Carbon is an innovative and unique company, developing several approaches that all address excess emissions in the atmosphere. The technology combines biomass pyrolysis, carbon mineralization, and direct air capture processes – all separate and can work independent of each other, however, they are all optimized in one single system. 

BluSky has a pyrolysis system called the “Vulcan” that takes in organic waste and converts it into biochar. The process also produces surplus syngas that is used to produce electricity which can power BluSky’s operations.

The biochar production process produces a certain amount of CO2 emissions. Some of the CO2 gets locked in the biochar, however, the rest is released and goes out in an exhaust stream and could be captured. The captured CO2 is mixed with industrial wastes to be mineralized into stable carbonates which is the second process of the system – the carbon mineralization one. The mineralization reactor is also called the “Medusa”. 

The surplus energy from the system powers the direct air capture process called the “Kronos”. The captured CO2 directly from the air is also mineralized into stable carbonates.

We talked to BluSky CEO William Hessert who answered some questions and shared valuable insights on the problems the technology could help solve. 

“There are a lot of people in the forestry industry that want to get into carbon removal because they have the feedstock. The biochar can be used to return nutrients back to these same forests. At the same time, it can be used to remediate everything from lead to microplastics. It can be converted into graphite for electric vehicle batteries. Biochar is an industrial feedstock for a variety of processes,” explained for Carbon Herald Mr Hessert.

To a question on why the company decided to develop a carbon mineralization process along with a DAC system and biochar production, Mr Hessert said: “That combination allows for maximum efficiency in the carbon removal process. Unfortunately, there is not a lot of infrastructure to dispose of the CO2 into wells. At many places there is not geology to even build a well, so they end up creating a mineralization technology that turns the CO2 into rock. 

We take in organic waste to make biochar and then we are able to take the CO2 that comes from this process and carbonate it. There is also a surplus energy stream that we wanted to do something productive with, so we edited our point source capture system to be able to remove atmospheric air. Now you have the pyrolysis and carbon mineralization all working together in one single system. If someone has a source of emissions and they just want to use the carbon mineralization process to mineralize it, they can do that. If they want to just take our DAC system and pump CO2 directly into a well, they can do that as well.”

The company’s business model has two main focuses – owning and operating its own carbon removal facilities and providing carbon credits, and offering equipment/project development services to other companies in the industry. Both paths ensure a quick and economical deployment of the carbon removal technologies. BluSky also works with potential buyers to sell carbon removal credits produced by both projects it owns and projects it develops.

Even though BluSky was founded in 2021, it already successfully activated its Vulcan II pyrolysis system back in January, which has a capacity to remove 800 tonnes of CO2 per year through the biochar production. It is currently building its next-scale pyrolysis unit – the Vulcan Heavy, capable of removing 20,000 tonnes of CO2 per year, expected to go live in the United States in the next few months. The company will be capable of deploying multiple Vulcan Heavies per year to other projects.

It has also developed already the Medusa system that can mineralize the exhaust output of the Vulcan II – a process that converts the bio-exhaust into carbonate rock. Right now, BluSky Carbon is finalizing the permitting for an Old Saybrook, Connecticut based carbon removal facility that will utilize multiple systems. The company plans to remove and sequester records amounts of atmospheric carbon dioxide in 2025.

The company has sealed a deal with the City of Minneapolis to provide a Vulcan II biomass pyrolysis system with support equipment as the city is launching a municipal biochar project. According to Mr Hessert, BluSky has secured another project development deal in North Texas to create a carbon removal facility. Additionally, it has already secured its first carbon offset agreement with SQUAKE.earth GmbH. The company has other deals in the pipeline for various contracts.

“The goal of BluSky Carbon has always been to remove gigatonnes of carbon dioxide per year. To advance that, we are looking to deploy many facilities throughout the world as quickly as possibly alongside local partners. In order to improve the economies of scale of carbon removal, we are working on a suite of tech and operational advancements that will allow the rapid deployment of massive CDR facilities worldwide. These developments are at too early stages to discuss now, but we will be announcing some exciting ones in the coming months,” explained Mr Hessert.
