24M Technologies vs 280 Earth
Side-by-side comparison of AI visibility scores, market position, and capabilities
24M Technologies developed the SemiSolid™ lithium-ion battery platform; raised $87M Series H in Sep 2024 at $1.3B valuation ($500M+ total); 100 MWh Thailand plant live; licensed to Kyocera, Asahi Kasei, and global OEMs;
About
24M Technologies is a Cambridge, Massachusetts-based battery technology company that developed SemiSolid™ — a novel electrode manufacturing process that replaces traditional solvent-based slurry coating (requiring toxic NMP chemical and energy-intensive drying ovens) with a semi-solid, binder-free paste that is directly coated and dried without solvents. The result is thicker, denser electrodes with higher energy density, lower manufacturing cost, and reduced environmental impact. The process eliminates approximately 80% of the steps in conventional lithium-ion battery manufacturing.
280 Earth uses engineered trees as a bio-based direct air capture system to remove CO2 from the atmosphere; converts captured carbon into biomass for bioplastics and biofuels; generates fresh water as a byproduct;
About
280 Earth is an early-stage biotechnology and climate company developing a bio-based direct air capture (DAC) system that uses genetically engineered trees to remove carbon dioxide from the atmosphere at scale. Unlike mechanical DAC systems (such as those developed by Climeworks or Carbon Engineering) that use chemical sorbents and large industrial equipment, 280 Earth''s approach leverages biological carbon fixation — engineering trees to capture CO2 more efficiently than natural forests — and then processes the resulting biomass to produce useful end products including bioplastics and biofuels, while also generating fresh water as a byproduct of the biological process.
