A Year in Review
Focus on our Climate Neutrality
Chlor-Alkali low-Carbon Hydrogen; an opportunity for our sector to contribute to Europe's decarbonisation.
Alongside Chlorine and Caustic Soda/Potash, we also have the production of low-Carbon Hydrogen. Putting this by-product to full use remains one of our sector's key climate commitments for 2050.
This also provides a genuine opportunity for our industry to position itself as an active, credible contributor to Europe's decarbonisation ambitions and its emerging Hydrogen economy.
Although the utilisation rate has progressed over the past three years, finding suitable offtakes for our Hydrogen remains a challenge. Many Euro Chlor members are unable to connect to the grid, whether due to their remote location or the absence of an adequate local pipeline network.
Euro Chlor continues to flag these infrastructure constraints with the relevant authorities, especially given EU ambition here.
Putting Hydrogen to work
Euro Chlor's webinar series on Hydrogen utilisation.
Turning our commitment into action on Hydrogen utilisation requires both inspiration and practical solutions.
To equip members with the knowledge and contacts needed here, since the spring of 2025, Euro Chlor has held a dedicated series of webinars bringing together innovative companies and technology providers in the Hydrogen space.
The series has cast a wide net, covering a diverse range of technologies and applications with topics ranging from Hydrogen certification schemes to the conversion of Hydrogen into electricity through fuel cell systems, the transformation of Hydrogen into value-added chemicals or fuels through biotechnology, on-site Hydrogen storage solutions, and the production of synthetic natural gas from Hydrogen and CO₂. Taken together, the sessions have showcased the breadth of pathways available for putting Hydrogen to productive uses, from grid electricity to advanced chemicals and beyond.

Facts and Figures
Facts and Figures about our sector's Climate Neutrality
Chlor-Alkali Hydrogen utilisation 
KPI
For the third consecutive year, we recorded an increase in Hydrogen utilisation, with the utilisation rate rising from 86.8% in 2024 to 87.6% in 2025. This continued progress reflects our sustained efforts to maximise the value of our Hydrogen.
2025 marked a third consecutive year of rising Hydrogen utilisation.
Primary fuel energy consumption KPI
To measure the overall energy footprint of the Chlor-Alkali sector, we use a metric that combines both electricity and steam consumption, expressed on a relative scale to ease comparison over time.
In 2025, our primary energy consumption reached 84.1% compared to 84.2% in 2024 (relative to the 2001 reference year).
As for previous years, lower production rates may be influencing this figure, as electrolysers are potentially run at lower current densities. When adjusted for the higher current densities associated with peak production (as in 2021), the 2025 figure rises to around 85.4%.
Energy and steam consumption KPI
In 2025, electricity consumption remained broadly flat compared to 2024. In part, this could be because gains become harder to achieve as we near the practical limits of how much energy can be saved with the current technology. However, Euro Chlor companies and their suppliers continue to explore further opportunities to improve energy efficiency.
Steam consumption continues to fluctuate, particularly when production levels are low. This may be something that is further compounded by shifts in customer concentration requirements for Caustic Soda.
Grid balancing
This graph shows the flexibility support offered by Euro Chlor members, expressed as a percentage of total installed electricity demand capacity, since data collection started in 2020.
In 2025, 19.0% of our capacity was available for grid balancing (down from 21.2% in 2024). This decline could be linked to the ongoing competitiveness challenges facing the European Chlor-Alkali sector, as flexibility requires substantial upfront investment.
Carbon footprint
Since we began monitoring the Carbon footprint of our members' production in 2020, we have observed a 28.3% decrease.
In 2025, however, our Carbon footprint rose for the first time, increasing by 2.1% to 0.79 tonnes of CO₂ per tonne of Chlorine produced (up from 0.77 tonnes in 2024).
This increase may be attributed to access to low-Carbon electricity and economic constraints on investment in energy efficiency or decarbonisation projects linked to our sector's competitiveness challenges.
