Preventing Scaling and Corrosion in Geothermal Facilities with Novel Lubricant-Infused Barrier Coating

The project aims to develop and demonstrate a novel superhydrophobic lubricant-infused composite (SLIC) barrier coating designed to prevent scaling and corrosion in piping systems at geothermal power plants located in the Salton Sea region of California. Harsh geothermal brines cause uncoated metals, including stainless steel, to scale rapidly within hours, but the SLIC coating’s slippery, lubricant-infused surface resists scale adhesion and allows any formed deposits to be easily removed with low-intensity cleaning. The work will involve applying the coating to internal pipe surfaces and testing its performance in operational conditions within the Calipatria, California facility, with deliverables focused on validating reduced scale formation, enhanced corrosion resistance, and improved cleaning efficiency. The project qualifies for categorical exemption under California Code of Regulations Title 14 Sections 15301 and 15306, as it involves minor alterations to existing facilities and constitutes a research activity with negligible environmental impact. The California Energy Commission is the approving agency, with Chuck Gentry listed as a mechanical engineer and Chad Haugen of Barr Engineering Co. as the project manager. The application was signed on June 5, 2025, and posted as a forecast on September 26, 2025, under NAICS code 541713. Place of performance is clearly identified as Calipatria, California, but no contract value, pricing details, period of performance, delivery schedule, or formal contract type is provided. No federal acquisition regulation clauses, payment office information, accounting data, invoicing methods, or contracting officer representatives are specified. The documentation contains no formal offeror certifications, small business status, unique entity identifiers, socioeconomic designations, or detailed evaluation criteria, indicating the materials are centered on environmental compliance rather than a competitive procurement process.
