Sperra

What Sperra does

Sperra (legally RCAM Technologies Inc.) develops 3D concrete printing (3DCP) technology and products for marine and offshore renewable energy infrastructure. The company was founded in 2017 by Jason Cotrell and is headquartered in San Pedro, California with operations in Boulder, Los Angeles, Rochester, London, and Aqaba, Jordan. Its portfolio spans three anchor lines (Gravity, Torpedo, Suction) marketed under an "Anchors on Demand" platform; two foundation products (Solar Reef for fixed-bottom nearshore solar and Canal Solar for irrigation canals); and Subsea Pumped Storage Hydropower, a long-duration storage concept using hollow concrete spheres on the seabed. The technology stack emphasizes localized manufacturing near project sites using locally sourced materials, with disclosed cost reductions of 63–75% versus steel alternatives and 50% lower carbon footprint.

The business operates a direct enterprise B2B model targeting offshore wind developers, floating solar developers, energy storage developers, and government agencies. Revenue streams include hardware sales of custom-engineered anchors and foundations, engineering consulting and 3D printing-as-a-service from its LA and New York facilities, and a wind farm design training program. Pricing is quote-based with multi-year contract cadence. Customer relationships are anchored by named enterprise and government counterparties including EDP, Fred. Olsen 1848, The Crown Estate, and the U.S. DOE; Sperra's funding to date is primarily non-dilutive, including a $4M DOE Water Power Technologies Office grant plus $3.7M from the German Ministry for Economic Affairs and Climate Action, a $650K DOE SETO award, a £1M Crown Estate Supply Chain Accelerator award, and a $1.25M California Energy Commission grant.

The company's competitive positioning rests on a patent-pending portfolio of marine-specific concrete designs, a multi-continent manufacturing footprint that enables port-adjacent production, and deep domain pedigree drawn from NREL, DTU, and MIT. The first full-scale commercial deployment — a 3D-printed gravity anchor at EDP's floating solar test site in Portugal — occurred in March 2026, marking the transition from pilot to commercial demonstration. Strategic direction is concentrated on scaling subsea pumped storage, the Floating Construction Station concept for UK offshore wind, and adjacent verticals such as coral reef restoration and canal-top solar.

Core offering

Sperra designs and manufactures 3D concrete printed anchors (gravity, torpedo, suction), fixed and floating foundations (Solar Reef, Canal Solar), and subsea pumped storage hydropower spheres for offshore wind, floating solar, canal solar, and long-duration energy storage applications. Each product is custom-engineered to project-specific loads, mooring layout, and site conditions, then manufactured on-demand using locally available materials at company-operated 3D printing facilities near project sites.

Product overview

Sperra delivers marine infrastructure on demand through localized and scalable 3D concrete manufacturing. The portfolio consists of three anchor product lines (Gravity Anchors, Torpedo Anchors, and Suction Anchors) marketed under the Anchors on Demand platform, two foundation products (Solar Reef for fixed-bottom nearshore solar and Canal Solar for agricultural canals), and Subsea Pumped Storage Hydropower for ocean-floor energy storage. The company also offers Custom 3D Printing services and Wind Farm Design Training. All physical products leverage 3D concrete printing to reduce costs, carbon emissions, and material usage compared to conventional steel or precast concrete solutions.
