What Sailh2 Energy Sociedad Limitada. does

SAIL H2 (legally SAILH2 INGENIERÍA SOCIEDAD LIMITADA, CIF B42999375) is a Spanish green hydrogen project development and engineering services firm founded in 2021 and headquartered in Sevilla, Andalusia. The company delivers integrated project management across the full lifecycle of green hydrogen infrastructure — from greenfield site identification through Ready-to-Build (RtB) status — across three service lines: Desarrollo (land acquisition, licensing, permitting), Ingeniería-Consultoría (engineering design and strategic consulting), and Construcción (EPC delivery). It targets industrial manufacturers, mobility operators, energy utilities, and gas network operators seeking to decarbonize operations, as well as renewable energy project developers and financial investors entering the hydrogen market. Core technology centers on water electrolysis (PEM and alkaline) powered by variable renewable sources, primarily solar PV, with proprietary integration of PV plants with electrolyzer systems and downstream applications spanning hydrogen refueling stations (hidrogeneras), industrial offtake via dedicated hydrogen pipelines (hidroductos), and blending/injection into existing natural gas networks.

Revenue is generated through project-based professional services fees (milestone and percentage-of-completion recognition), engineering consulting (project or hourly billing), EPC construction contracts, and emerging long-term hydrogen production contracts. The company's flagship projects include H2GREEN LA ISLA (multi-phase 26+ MW hub in Dos Hermanas, Sevilla), GEDISOL ENERGÍA (solar-integrated hydrogen plant in Alcalá la Real, Jaén), and HEROGRA FERTILIZANTES (Spain's first industrial green hydrogen plant in Albolote, Granada, achieving 20% natural gas reduction via blending). Founders Dr. Fernando Isorna Llerena and Dr. Eduardo López González bring 30+ years of hydrogen R&D from INTA. Go-to-market is exclusively direct enterprise sales via consultative engagement in Spain and the broader Iberian Peninsula, with active memberships in AEH2 and the Clúster Andaluz del Hidrógeno. No institutional funding or revenue is disclosed; the company remains founder-owned and operated as a private Sociedad Limitada.

Core offering

SAIL H2 provides integrated project management, engineering, consulting, and construction services for green hydrogen production facilities powered by renewable energy (primarily solar PV). The company manages the full lifecycle from greenfield site selection and licensing through to Ready-to-Build (RtB) status, including specialized hydrogen engineering design and EPC delivery of electrolyzer-based plants for power-to-mobility, power-to-industry, and power-to-gas applications across the Iberian Peninsula.

Product overview

SailH2 (SAILH2 INGENIERÍA SOCIEDAD LIMITADA) provides integrated management services for green hydrogen projects across the entire project lifecycle from Greenfield to Ready to Build (RtB). The company operates three core service lines: Desarrollo (Project Development) for land acquisition, licensing, and permit management; Ingeniería-Consultoría (Engineering and Consulting) for specialized design and strategic advisory; and Construcción (Construction) for plant engineering and build-out. The company is developing a portfolio of over 1.5 GW of green hydrogen production projects across the Iberian Peninsula, with notable projects including H2GREEN LA ISLA (a multi-phase commercial hydrogen hub in Seville), GEDISOL ENERGÍA (a solar-powered hydrogen plant in Jaén), and HEROGRA FERTILIZANTES (an industrial thermal hydrogen project in Granada). The company specializes in hydrogen production for power-to-mobility, power-to-industry, and power-to-gas applications including natural gas network injection.
