Green Hydrogen & Carriers

Unlocking the potential of hydrogen for a net-zero future

Scaling green hydrogen and carriers into real energy solutions

At Sener, we see green hydrogen as one of the most strategic tools for achieving climate neutrality. Produced through electrolysis powered by renewable energy, it provides a clean and versatile energy vector that can decarbonize industries, mobility, and power generation. With our multidisciplinary engineering and EPC delivery capacity, we are at the forefront of making hydrogen a practical solution for real economies.

We turn pioneering projects into scalable energy solutions

Sener has consolidated its role as a pioneer in the hydrogen sector with flagship projects in Spain and Europe. The BenortH2 project is designed to produce more than 20,000 tonnes of green hydrogen annually, avoiding about 120,000 tonnes of CO₂ emissions per year. In Extremadura, the Vector H project will combine a 5 MW electrolyser with photovoltaic generation to produce hydrogen for refuelling stations serving trains, heavy trucks, and light vehicles, and for blending into the gas grid, with operations starting in 2026.

Why choose us 

The strength of our approach lies in scalability. BenortH2 demonstrates how hydrogen can be integrated into existing networks and industrial processes at large scale, while Vector H shows its viability in local mobility, distributed supply, and grid blending. By delivering projects across different scales, we prove that green hydrogen and carriers are not just pilot initiatives but the foundation for replicable, global energy solutions.

How we work 

Our methodology combines applied research, conceptual analysis, and turnkey execution.

We begin with studies comparing carriers such as compressed hydrogen, liquefied hydrogen, ammonia, methanol, and liquid organic options, identifying the most competitive solution for each application.


In design, we integrate renewable generation, electrolyser technology, storage tanks, and carrier conversion systems, using advanced digital modelling and economic analysis to validate performance.


During execution, we manage EPC contracts that cover everything from electrolysers and balance of plant to compression systems and export facilities.


Finally, we support long-term operation with predictive maintenance, monitoring, and upgrades to ensure that plants evolve with market demand and regulatory requirements.

We integrate hydrogen into real economies and industrial systems

Our projects are conceived to have immediate industrial impact. By linking hydrogen generation with refuelling stations, power plants, and chemical conversion, we accelerate adoption across multiple sectors. Through hydrogen carriers such as ammonia and methanol, we open pathways for international trade, transforming renewable molecules into globally tradable commodities.

Global experience that translates into local impact.

Our expertise is reflected in projects like BenortH2 and VectorH in Spain, the H2Ocean initiative for maritime mobility, and hydrogen-ready power plants in Germany.
