SOLATOM

What SOLATOM does

SOLATOM (legal entity Solatom CSP S.L.) is a Valencia-headquartered, privately held Spanish engineering company that designs, manufactures, and commercializes modular linear-Fresnel solar steam boilers for industrial process heat. Founded around 2016 and operating with 1–10 employees, the company builds the FLT20 — a plug-and-play, container-sized Fresnel concentrator manufactured in Castellon, Spain — that delivers up to 14.5 kWt per module (26.4 m² aperture), reaches 450°C and 30 bar, and supports steam, pressurized hot water, thermal oil, and hot air. Modules can be connected in arrays to scale to multi-megawatt installations, with the flagship 4.2 MW commercial deployment at the Heineken brewery in Quart de Poblet (Valencia) operating under a Heat Purchase Agreement (HPA). Complementing the hardware, SOLATOM monetizes engineering and simulation services via its ReSSSPI software (built on the open-source SHIPcal engine, validated against IEA SHC Task 64), supplies laboratory-scale Fresnel demonstrators to research centers, and maintains a proprietary database of more than 178,000 Spanish industrial sites used to qualify and route leads through a partner network of engineering and installer companies.

SOLATOM's go-to-market is hybrid: direct enterprise field sales to industrial end-users who want to decarbonize boiler consumption; a B2B partner/reseller channel (Partner Support Tool with database + simulator + technical support) targeting engineering and installer firms in Spain; and international project deployments via containerized module shipments through partners such as SUNVAPOR (US) and direct relationships with corporates and government entities (Heineken, Unilever, SWCC Saudi Arabia, Dyechem Morocco, SPARC Australia). Commercialization of multi-MW plants is executed through a wholly-owned subsidiary, CSIN. Revenue streams span managed-services/HPA recurring revenue (Heineken), one-time hardware sales of FLT20 modules, professional engineering and simulation services, and R&D grants from Spanish/EU programs (CALIHPSO, SOLPINVAP, MICROGENVASOL, SOLPINREF, CREATEC, inSHIP). The company holds the Solar Impulse Efficient Solution Label and Pyme Innovadora recognition, has ISO 9806 performance validation at Plataforma Solar de Almería, and is an active participant in IEA SHC Task 64 and IEC TC 117/147 standards-setting for linear Fresnel collectors.

The company's strategic positioning is concentrated in industrial decarbonization of low-to-medium temperature process heat, a market where industrial heat accounts for roughly 75% of industrial energy demand and is still largely fossil-fuel-based. As of mid-2024, SOLATOM has delivered 23+ projects across 6+ countries since 2017, anchored by a single 4.2 MW commercial HPA but with a growing pipeline of international pilots and commercial deployments. Capital structure includes a 2017 Lanzadera Accelerator ticket and a May 2024 round with Enagás Emprende, CDTI (Innvierte), Enion, Grupo Dominguis (GDES), and White Summit Capital. Founded by CEO Miguel Frasquet Herraiz (PhD, Solar Energy, University of Seville), CFO Raul Villalba, and CTO Juan Martínez, SOLATOM remains a small, capital-light specialist with the bulk of its 23+ installations at demonstration or pilot scale rather than full commercial scale.

Core offering

SOLATOM designs, manufactures and sells modular linear Fresnel solar boilers (FLT20 modules) that concentrate sunlight to generate industrial process heat — saturated steam up to 30 bar, pressurized hot water, thermal oil up to 450°C, and hot air — for factories that currently rely on fossil-fuel boilers. Each pre-assembled module fits in a 20-foot shipping container, delivers 14.5 kWt, and is deployed in parallel with existing boilers; the company also offers the ReSSSPI solar simulation tool, a Partner Support Tool with a database of 178,000 Spanish industries, and delivers full solar plants under Heat Purchase Agreements via its CSIN subsidiary.

Product overview

Solatom offers a single integrated platform for industrial solar process heat, built around a core physical product (the FLT20 modular linear-Fresnel solar boiler) plus digital and partner enablement layers: the ReSSSPI simulation tool (powered by the SHIPcal engine), the Partner Support Tool (which combines a database of 178,000+ Spanish industries with ReSSSPI and Solatom engineering support), R&D-grade FLT10/FLT12 Fresnel demonstrators for research institutions, the proprietary Industrial Potential Database that feeds the partner network, and commercial deployment via the CSIN subsidiary. The FLT20 modules are manufactured in Castellon, Spain, can be container-shipped and 'unfolded' on site, and are deployed either as standalone solar-steam plants or in hybrid/parallel configurations with conventional gas, biomass, or fuel-oil boilers.
