What Terrabarrier does

TerraBarrier AB is a privately held Swedish materials technology company founded in 2023 and headquartered in Karlstad, Sweden, that develops a proprietary inward-growing protective barrier coating for metals. Unlike conventional surface coatings that add a layer on top of a substrate, TerraBarrier's technology forms a thermodynamically stable, defect-free, super-dense layer from within the metal itself, eliminating dimensional change to the coated part. The barrier is designed to protect stainless steels, nickel-based alloys, and alumina formers against hydrogen permeation, hydrogen embrittlement, corrosion from acids, alkaline, salts and ammonia, nitridation, high-temperature oxidation, thermal fatigue, and fouling. The company has translated the core technology into a portfolio of application-specific coating offerings for heat exchangers, industrial burners and turbines, additive-manufactured (3D-printed) components, valves and fittings, and engine parts. TerraBarrier's production process is emissions-free, REACH-compliant, EU Green Deal-aligned, and free of Cr6+ and Critical Raw Materials.

The company sells through a direct enterprise field-sales motion targeting industrial customers in hydrogen infrastructure (fueling stations, production, storage, valves, compression), chemical processing, aerospace, automotive (including hydrogen propulsion), and general industrial manufacturing. Customer engagement is qualification-heavy, with multiple case studies referencing NDA-protected pilots with leading heat exchanger manufacturers and major engine manufacturers across aviation, automotive, and alternative propulsion. Pricing is quote-based and not publicly disclosed, and the company has not announced any equity funding rounds; capitalization appears to rely on non-dilutive support from EU innovation programs and Vinnova (Sweden's national innovation agency) alongside revenue from coating services. Technology validation is anchored by independent testing at RISE Research Institutes of Sweden, Element Materials Technology, and MECM, plus research collaborations with Harvard University and Chalmers University of Technology, with field testing reported at hundreds of millions of cycles.

TerraBarrier is led by CEO Jonas Wallmander (formerly CEO of listed energy storage company Azelio and previously at REC Solar), CTO Dr. Anna Carlson (academic background from Harvard and Chalmers), COO Dr. Torbjörn Lindquist (background across energy, aerospace, and maritime), and Working Chairman Erik Sävenstrand (M&A advisory and venture capital background). The firm operates with 1-10 employees and is registered as a Swedish private limited company (Aktiebolag). Its competitive position rests on a novel coating architecture, regulatory-aligned sustainability credentials, and academic-grade validation; its commercial position is early-stage, with pilots in progress across multiple industrial verticals rather than recurring contracted revenue at scale.

Core offering

TerraBarrier develops and applies a proprietary inward-growing protective barrier coating for metal components that virtually eliminates hydrogen permeation and provides superior resistance to corrosion, nitridation, and high-temperature degradation. The coating forms a thermodynamically stable, defect-free layer from within the metal substrate, with no dimensional change to the part, and is delivered as application-specific solutions for heat exchangers, burners, 3D-printed parts, valves and fittings, and engine components used by industrial customers in hydrogen infrastructure, chemical processing, aerospace, and automotive sectors.

Product overview

TerraBarrier offers a core protective barrier coating technology that provides defect-free, inward-growing metal protection against corrosion, hydrogen permeation, nitridation, and high-temperature degradation. The technology is validated for use on stainless steels, nickel-based alloys, and alumina formers. The product portfolio includes application-specific coating solutions for heat exchangers, burners, additive manufacturing (3D printing), valves & fittings, and engine parts. Each application-specific product leverages the same core barrier technology but is tailored to address the unique degradation challenges of that component type, including protection against hydrogen embrittlement, thermal cycling, and corrosive environments.
