Phoenix Energy provides reliable, cost-competitive renewable energy from high-hazard fuels and landfill-bound agricultural waste. Its bioenergy with carbon capture and storage (BECCS) plants are community scale and built at the fuel source, producing electricity, heat and biochar sold to utilities, municipalities and farmers. The company has delivered clean, reliable renewable electricity and carbon removal since 2010.

Capture6 operates an integrated system that turns saltwater into fresh water while removing atmospheric CO₂, capturing and storing it. The company replaces brine ponds and other expensive brine disposal methods at no additional cost, and generates revenue streams through byproducts like freshwater and green chemicals. It partners locally on expansions of existing infrastructure to save project partners operational costs, and ran a test deployment in Perth to de-risk carbon removal technology before scaling to partner sites.

Carba converts waste biomass into solid biocarbon for use in industrial materials, permanent carbon removal, and pollution management. Its proprietary modular reactors use a self-regulating thermal battery to produce stable, high-yield biocarbon for industrial inputs and landfill burial. The company's process fits with existing waste management processes and co-locates storage and biomass collection for scalable project delivery.

CarbonCapture Inc. develops modular, scalable direct air capture (DAC) systems designed for mass production, capturing CO2 from the atmosphere and permanently storing it underground. The company sells DAC-based carbon removal credits and was named a 2023 Technology Pioneer by the World Economic Forum. Its subsidiary True North Carbon is launching the Tamarack direct air capture deployment in Canada.

Carbon Lockdown was founded by Dr. Ning Zeng in 2022 as a benefit corporation. Its mission is to develop and deploy cost-effective, scalable Wood Vault carbon removal and MRV technologies to benefit the climate, ecosystems, and rural communities. Wood Vaults bury sustainably sourced woody biomass underground in low-permeability soil, creating an anoxic environment that halts decomposition and provides durability of 1,000 years or more.

Vaulted builds and operates permanent disposal infrastructure for organic waste, putting it deep underground. The company turns organic waste into a slurry and places it thousands of feet underground using proven oil and gas technology, permanently isolating waste in deep rock formations and layers of steel and cement. It operates facilities including Great Plains in Hutchinson, Kansas (since 2023) and Terminal Island in Los Angeles, California (since 2008), and has proposed Monarch Fields in Weld County, CO.

Charm Industrial provides high-quality carbon removal through bio-oil sequestration. The company uses plants to capture CO₂ from the atmosphere, converts biomass into a stable, carbon-rich liquid (bio-oil) via fast pyrolysis, and injects it into EPA-regulated injection wells where it sinks and solidifies in place for permanent storage.
