Clean Project

1. REFHYNE 2, 100MW electrolyser in Germany

Refhyne 2 is a landmark in Europe’s hydrogen scale‑up, transforming the success of the 10 MW Refhyne I electrolyser into a full industrial project 10 times larger. Refhyne I has already demonstrated safe, reliable operation since 2021, producing 1,300 tonnes of renewable hydrogen per year and helping stabilise the local grid by using surplus wind power. Building on these proven lessons, Shell’s Final Investment Decision in 2024 launched REFHYNE 2: a 100 MW renewable PEM electrolyser that will deliver up to 44 tonnes of low‑carbon hydrogen per day and decarbonise operations at the Energy and Chemicals Park Rheinland. With start‑up expected in 2027, Refhyne 2 exemplifies real‑world hydrogen deployment at scale — proven technology, industrial integration, and meaningful CO₂ reduction — making it a standout contender for Clean Hydrogen Project of the Year.


2. Worley Nederland BV, The Netherlands

First large Green Hydrogen Plant (200 MW) in Europe. Shell - Holland Hydrogen I on the Maasvlakte in The Netherlands. The plant will be started up in 2026 and will produce Green Hydrogen to Shell Refinery in Pernis, The Netherlands. The plant will use energy for Hollandse Kust Noord windfarm. 10 Electrolysers of Alkaline type, 2 compressors for transport to Pernis.


3. Air Products - NEOM Green Hydrogen Company   

Building the world’s largest at scale green hydrogen plant.

In the final completion phase, the NEOM Green Hydrogen Company is delivering the world’s largest fully integrated green hydrogen project, underpinned by a 30 year exclusive offtake agreement with Air Products that ensures long term commercial viability and sets a new global benchmark for clean energy.

Powered by ~4 GW of dedicated solar and wind energy, the facility will produce up to 600 tons of green hydrogen per day, converted into 1.2 million tons of green ammonia annually to decarbonize hard to abate sectors worldwide.

The project pioneers the world’s first export scale renewable based hydrogen system, proving industrial scale production and establishing a replicable blueprint for international clean hydrogen supply chains. Its cutting edge integration of renewable generation, 2.2 GW electrolysis, hydrogen storage, and ammonia conversion demonstrates system level optimization and cost effective hydrogen transport. 

Aligned with Saudi Arabia’s Vision 2030, NGHC is also developing a skilled, Saudi led workforce through specialized training programmes. Particularly women who now represent 13% of our workforce (Q1 2025).

4. Repsol Renewable and Circular Solutions, S.A, Spain

Repsol is developing a renewable H2 project that integrates its electrolysis pipeline into a single industrial initiative, reinforcing its leadership as the largest H2 producer and consumer in the Iberian Peninsula. The project began in 2024 with the 2.5 MW ELY at Petronor, providing the experience to scale up through the 4 MW unit in Sines and the 10 MW ELY in Bilbao coming into operation in 2026. At the same time, we are developing digital tools for intelligent energy supply and sustainability traceability to improve efficiency across the value chain. It also includes large-scale electrolyzers under construction: 100 MW units in Cartagena and Petronor, and a 150 MW ELY in Tarragona, close to FID. Altogether, they will produce over 50,000 t/year of renewable H2 and reduce more than 500 ktCO₂/year, strengthening technological scalability, the H2 market, and energy security. An ambitious project with a structured growth pathway driven by learning and digitalization.


5. Hy4Chem, Siemens Energy, Germany

At BASF’s Ludwigshafen site, the company has commissioned Germany’s largest PEM electrolyzer for renewable hydrogen production in 2025 https://www.basf.com/global/en/media/news-releases/2025/03/p-25-046

The 54 Megawatt Hy4Chem electrolyzer by Siemens Energy is directly integrated into the chemical production environment and can produce one ton of renewable hydrogen per hour, with the potential of enabling an annual reduction of up to 72,000 tons of CO₂.

This post by the Canadian Hydrogen Association shows the global impact of such projects: https://www.linkedin.com/posts/canadah2_siemensenergy-basf-germany-activity-7421626036817354753--a8E

The facility’s hydrogen can be used for chemical production processes, from ammonia and methanol to specialty products, and for local public transport. BASF and Siemens Energy collaborate closely, sharing operational insights and ensuring safety in every phase.
