Carbon Dioxide Capture

Reverion, a German-based startup, is developing new generation micropower plants that maximize the potential of biogas and utilize excess solar wind and wind power that would otherwise go to waste. Reverion has patented and validated a novel technology based on high-temperature fuel cells. This is the first all-in-one solution with a reversible system design that electrochemically converts biogas or hydrogen into electricity with an efficiency of 80% and can switch to electrolysis mode to produce green hydrogen or methane. 

Fairbrics, a French startup, is leading the charge in creating sustainable alternatives to traditional textiles. Their innovative process, which involves capturing CO2 from industrial sources and converting it into polyester fabric, is a beacon of hope for the fashion industry. By offering a more eco-friendly alternative, Fairbrics is not just reducing the industry’s reliance on fossil fuels but also inspiring a greener future. 

CarbonFree’s SkyCycle™ technology is a groundbreaking solution for capturing CO2 emissions from hard-to-abate industrial sources and transforming them into valuable, carbon-negative products. SkyCycle™ captures carbon emissions before they enter the atmosphere, decarbonizes, and mineralizes the CO2, converting it into marketable, non-hazardous materials or permanently storable compounds. This process yields significant carbon value, helping to reduce global supply chain emissions, particularly Scope 3 emissions.

Gefn is an Icelandic chemical engineering startup focused on producing and commercializing green chemicals for various industries. The company’s innovative technology replaces fossil-based feedstocks by converting low-value by-products, such as glycerol and fatty acids, and climate-neutral CO2 captured through direct air capture (DAC) and biomass fermentation into valuable carbonates and esters. These green chemicals serve as specialty chemicals, solvents, and intermediates in applications ranging from cleaning products and cosmetics to pharmaceuticals and batteries.

Nextchem is an Italian company within the Maire Tecnimont Group and is dedicated to Sustainable Technology Solutions. The company's expertise in nitrogen, hydrogen & circular carbon, fuels & chemicals, and polymers, allows Nextchem to deliver groundbreaking solutions and processes to fully support energy transition. Building on the group's 70+ years of operation, Nextchem is dedicated to developing and offering technology solutions, processes, basic engineering designs, proprietary equipment, and catalysis to drive global decarbonization forward.

Enerkem specializes in converting waste materials into biofuels and renewable chemicals using patented gasification technology. This process utilizes waste and biomass residues from municipal, commercial, and industrial sources. The waste is initially sorted to remove recyclable and inert components, then shredded and dried for further processing. In the gasification phase, the prepared waste is fed into a proprietary bubbling fluidized bed gasification vessel, where it reacts with steam and oxygen to break down molecules and produce a mixture called syngas.

Solidia Technologies has patented cement technology that utilizes the same raw materials and equipment as traditional Portland cement but with reduced limestone and lower production temperatures. This innovation slashes CO2 emissions from kilns by 30% compared to conventional Portland cement production and up to 50% of the overall carbon footprint of cement and concrete. Solidia Cement® also contains low-limestone cement that achieves strength through CO2 reaction rather than water.

The Travertine process converts aqueous sulfate into sulfuric acid and caustic solutions through electrolysis, generating clean and competitively priced hydrogen. The process involves three primary units. Initially, electrolysis divides aqueous sulfate into sulfuric acid and caustic solutions. Subsequently, Direct Air Capture (DAC) utilizes the caustic solution to extract CO2 from the air, yielding a carbonate solution. Lastly, the carbonate solution reacts with sulfate byproducts to form minerals and regenerate aqueous sulfate through mineralization.
