Dutch climate tech converting captured CO2 into building materials. Carbon mineralization 10M times faster than nature. $25M raised. World's first CO2-neutral bridge.
Paebbl is a Dutch climate tech company founded to commercialize carbon mineralization — a process that permanently converts captured CO2 into solid carbonate minerals used in construction materials. The company was founded on the scientific insight that natural rock weathering sequesters carbon dioxide over geological timescales, and that this chemistry can be accelerated by 10 million times in an industrial process to produce building materials with a net-negative carbon footprint. Paebbl's core technology converts waste CO2 streams into calcium and magnesium carbonates that can replace conventional aggregates, fillers, and binders in cement and concrete.\n\nThe company's primary product is the world's first commercially viable CO2-derived building material, produced by reacting captured carbon dioxide with alkaline industrial wastes such as steel slag and mine tailings. This dual-use approach both sequesters carbon and upcycles industrial waste, improving the economics of carbon removal compared to storage-only approaches. Paebbl's materials target the construction industry, one of the largest emitters of CO2 globally, and are designed to be drop-in compatible with existing concrete and cement manufacturing workflows.\n\nPaebbl raised $25M to scale its production technology and advance commercial partnerships with construction and industrial companies. The company is headquartered in the Netherlands and operates at the intersection of carbon capture utilization and storage (CCUS), circular materials, and green construction. As demand for verified carbon removal credits and low-carbon building materials accelerates, Paebbl is positioned as a rare company that can monetize carbon removal twice — through the building material itself and through associated carbon credits.
Frankfurt-listed (ETR: ENR) energy technology company at €34.5B FY2024 revenue with 13-15% growth 2025; Siemens Gamesa offshore wind and gas turbines competing with GE Vernova and Vestas for energy transition infrastructure.
Siemens Energy AG is a Munich, Germany-based energy technology company — listed on the Frankfurt Stock Exchange (ETR: ENR), partially owned by Siemens AG (25%+ stake) following the September 2020 spin-off — providing power generation (gas turbines, steam turbines, generators), grid infrastructure (transmission technology, HVDC systems, transformers), and energy transition solutions (green hydrogen, offshore wind through its 73%-owned Siemens Gamesa Renewable Energy subsidiary) to utilities, industrial customers, and governments globally. Siemens Energy generated €34.5 billion in revenue in fiscal year 2024, with Q2 FY2025 revenue of €10.0 billion (+20.7% comparable) and Q3 FY2025 revenue of €9.7 billion (+13.5% comparable), projecting 13-15% revenue growth for full-year FY2025 at a 4-6% profit margin.
