Terra Block

What Terra Block does

Terrablock is a South Korean materials company founded in 2021 and headquartered in Busan that specializes in the mass production of Metal-Organic Frameworks (MOFs). Its commercial portfolio comprises two product lines: TERRA MOF-1, built on CAU-10-H (aluminum hydroxide isophthalate), which adsorbs water from air at relative humidities as low as 16% and captures more than 300g of water per kg of MOF, targeting desalination, adsorption heat pumps, and atmospheric water harvesting; and TERRA MOF-2, a functionalized MOF that adsorbs CO2 in the gas phase, releases it in the liquid phase, and supports catalytic conversion of CO2 into hydrocarbon fuels. The company emphasizes proprietary mass-production technology as its core differentiator, claiming to overcome the gram-scale limitations typical of academic MOF synthesis to enable kilogram- and larger-batch supply.

The company sells directly through its website via an inquiry-based model, with contact forms for product, cooperation, and general inquiries. It maintains two operational sites — the Busan headquarters (Centum Green Tower) and an Incheon branch with R&D Lab 217 at the Environment Industry Research Complex. Customers are undisclosed and pricing is not public; the only disclosed funding is an early-stage round closed on 2022-06-14 with Lotte Ventures and Newborn Ventures. Terrablock operates as a private corporation with a small named leadership team (CEO Kwon Ki-baek; Resource Team Leader Oh Geon-sik) and serves industrial segments in water management and carbon capture/utilization, primarily across East Asia with global outreach via direct website inquiry.

Core offering

Terra Block manufactures and sells Metal-Organic Framework (MOF) materials at scale, with two primary product lines: TERRA MOF-1 (CAU-10-H) for atmospheric water capture and TERRA MOF-2 for CO2 adsorption and conversion to hydrocarbon fuels. The company leverages proprietary mass-production technology to supply MOFs in commercial quantities for industrial water management and carbon capture applications.

Product overview

Terrablock is a mass production MOF (Metal-Organic Framework) company specializing in two distinct product lines: TERRA MOF-1 for atmospheric water harvesting using CAU-10-H technology, and TERRA MOF-2 for CO₂ capture and conversion to hydrocarbon fuels. Both products leverage proprietary MOF adsorption mechanisms but serve different applications—water capture and carbon conversion respectively.

Direct peers

• Atomis (formerly MOF Technologies): Atomis is a direct MOF manufacturer developing sorbents for gas storage, separation, and capture applications. Direct overlap with Terra Block on MOF chemistry, product format, and target end-uses (carbon capture, gas separation).
• Framergy: Framergy is a specialty chemical company built on Metal-Organic Framework technology commercializing MOFs for industrial gas storage, separation, and capture — competing head-to-head with Terrablock on MOF-based adsorption products.
• Mosaic Materials (a Baker Hughes company): Mosaic Materials develops MOF-based sorbents for direct air capture of CO2. Direct competitor to Terra Block's TERRA MOF-2 in the MOF-enabled CO2 capture space, now backed by Baker Hughes' industrial scale.
• NuMat Technologies: NuMat commercializes MOFs and related advanced adsorbent materials for industrial gas storage and separation applications. Comparable IP-light, specialty-chemical MOF manufacturer competing in similar end-markets.

Broad incumbents

• BASF: BASF is a global chemical incumbent that has invested in MOF partnerships (e.g., with Atomis) and serves as a broad-spectrum supplier/competitor in industrial adsorbents. Represents the well-capitalized incumbent that could commoditize or license Terra Block's technology.
• Svante: Svante develops solid sorbent-based carbon capture systems for industrial point sources and direct air capture. Different sorbent chemistry but directly competes with Terra Block in the post-combustion CO2 capture value chain.
• Climeworks: Climeworks is a leading direct air capture company using amine-based sorbents. It competes with Terra Block for the same atmospheric CO2 removal value pool, even though the underlying sorbent chemistry differs.
• Watergen: Watergen commercializes atmospheric water generation systems using a different (thermoelectric) approach. It competes with Terra Block in the same atmospheric water harvesting use case, validating the market while highlighting that MOF is one of several competing technical paths.
