![]() ![]() The product can be used as a carbon-neutral building material or to make synthetic fuels. Its technology converts the CO2 to limestone through a mineralization process it's stored onboard and then sold on. What it does: Seabound retrofits cargo ships with its carbon-capture technology to extract CO2 before it's emitted into the atmosphere. Recommended by: Ryan Orbuch, a partner at Lowercarbon Capital Seabound's cofounders, Alisha Fredriksson and Roujia Wen. These include cement companies, oil majors, and power plants, to name a few." "They are receiving inbound requests from carbon emitters on a monthly basis as emissions penalties and net-zero targets are kicking in, and current solutions available are expensive, which shows the need for this type of solution. Why it's poised to take off: "The business model not only services the carbon emitters but has the potential to sell the materials on at the same time, which makes it attractive," Velho said. While the company doesn't capture the carbon itself, converting it into materials is a form of sequestration. It says its thermo-catalytic process is used primarily to create carbon nanotubes - which can be used for energy storage and in car parts and boat hulls - but also creates other nanomaterials. What it does: Cool Corp aims to create a profitable, scalable, and permanently carbon-negative solution for all carbon emitters by using captured CO2 to create carbon-based materials. Recommended by: Sie Ventures' Nicole Velho Tommy Zijian Zhao and Josephine Tyler, the cofounders of The Cool Corp. The startup is filing its process patent and is set to bring the first certified concrete mixes to market in early 2023, the investor added. ![]() "EcoLocked is ideally positioned to capture the upcoming demand for zero-carbon materials," she said. Linamagi added that the industry is shifting from "operational emissions" to "embodied emissions." "Biochar locks away carbon for hundreds to thousands of years, meaning that new construction can offset its emissions footprint through using it to lock away carbon - this massively improves the sector's footprint." "This means solutions for this sector are essential to any global strategy to sequester carbon," Schwarzenbrunner told Insider. The International Energy Agency said that in 2018 the sector accounted for 36% of final energy use and 39% of energy- and process-related CO2 emissions. The cement industry is thought to be responsible for about 8% of global CO2 emissions. Why it's poised to take off: The construction industry is a major contributor to climate change. It also markets carbon-removal certificates and green energy from its production plants. The company told Insider it has a triple impact: reducing emissions in the construction sector by replacing some cement, increasing the energy efficiency of buildings, and locking in additional carbon dioxide over a building's lifetime. It says it can be integrated with existing processes at a small extra cost and tailored to different concrete applications. What it does: EcoLocked lets building owners, architects, and civil engineers use biochar as a building material, mixed with concrete.ĮcoLocked hopes its strategy will help decarbonize the construction industry.

"Investing in R&D and things that currently look very expensive and unrealistic - if we don't start that now, then they will continue being unrealistic and expensive," Nachmany said. Nachmany said investors, governments, and corporations must be bullish on carbon removal despite the high costs. ![]() It expects the cost of its current direct-air-capture technology to be $250 to $300 a ton by 2030. Many technologies are new, unproven, and costly, making them difficult to scale.Ĭlimeworks, which runs a direct-air-capture plant in Iceland, has said it's convinced the global price of carbon will settle in the range of $100 to $200 a ton once the urgency and necessity of carbon removal are fully understood and the right policies are in place. Nachmany, whose startup is building a searchable database of global climate policies, added that carbon-removal technologies should be used in addition to reducing emissions, "not instead of."Ĭarbon removal is a nascent industry. "We will need to do all of these things, because we will need to move from net zero to net negative," Michal Nachmany, the founder of Climate Policy Radar, told Insider.
