HY4Link Cross-Border Hydrogen Corridor Links Belgian Import Hubs to French Industry

A new cross-border hydrogen infrastructure project announced in June 2024 will link Belgium’s seaport import terminals to industrial consumers in northeastern France, creating a 400-kilometre corridor that could supply both steel production and emerging Power-to-Liquid e-fuel plants across the Greater Region by the early 2030s.

From Import Terminals to Industrial Heartland

The HY4Link corridor is designed to connect large-scale hydrogen import facilities under development at Belgian seaports—including the BE.Hydrogen initiative at the Port of Antwerp-Bruges—with demand centres in Luxembourg and France’s Grand Est region. Fluxys Belgium, Creos Luxembourg, GRTgaz, and Teréga are developing the infrastructure as an integrated project targeting commissioning in 2031.

The pipeline will initially transport imported renewable hydrogen, primarily produced via electrolysis in regions with abundant wind and solar resources such as the Iberian Peninsula and North Africa. Over time, the corridor could also accommodate domestically produced hydrogen, including potential supplies from natural geological hydrogen deposits such as those discovered in Lorraine and currently being evaluated through the REGALOR II drilling programme. AI-assisted seismic interpretation and geological mapping are accelerating the identification of serpentinisation zones that may host exploitable white hydrogen reservoirs across the wider region.

Power-to-Liquid Offtake Potential

While the HY4Link project primarily targets steel, chemicals, and refining sectors, the corridor’s route through northeastern France positions it to supply future Power-to-Liquid e-fuel production. The Grand Est region is home to several industrial clusters exploring e-methanol, e-diesel, and synthetic kerosene production to meet ReFuelEU Aviation and FuelEU Maritime mandates. These facilities require secure, cost-competitive hydrogen feedstock at scale—exactly the value proposition HY4Link offers.

The project’s 2031 timeline aligns with the ramp-up phase for European e-fuel mandates, which require 2 percent SAF blending in aviation fuel from 2025, rising to 6 percent by 2030 and 20 percent by 2035 under ReFuelEU. Maritime e-methanol demand is similarly accelerating under FuelEU, creating a potential multi-sector offtake base for hydrogen transported via the corridor.

Geology, Imports, and Regional Decarbonisation

HY4Link’s strategic significance extends beyond infrastructure. By linking the North Sea import hubs to the geologically promising Lorraine basin, the corridor creates optionality: imported hydrogen can flow east to meet near-term demand, while future domestic geological production could flow west to ports or be consumed locally. This bidirectional flexibility hedges against supply uncertainty and price volatility in global hydrogen markets, a critical consideration for capital-intensive e-fuel plants that require decades of predictable feedstock access to achieve investment-grade economics.

Bottom Line

HY4Link’s 400-kilometre cross-border hydrogen corridor represents more than transmission infrastructure—it is a strategic enabler for Power-to-Liquid e-fuel production in northeastern France, linking Belgian seaport import capacity with industrial demand centres while creating optionality for future domestic geological hydrogen supplies from the Lorraine basin and adjacent serpentinisation zones now being mapped with AI-assisted seismic tools.
