Leclanché: Engineering Battery Storage for Grid Stability and Electrified Mobility
Pierre Blanc, Vice President Operations
Battery storage systems often run into trouble long after deployment. Different components may work well individually, yet fail to perform consistently once exposed to changing grid conditions, demanding charging cycles or continuous industrial use. Utilities, transport operators and infrastructure providers need storage platforms that can respond to fluctuating renewable generation while handling large-scale energy requirements without compromising stability.
Leclanché has concentrated on those challenges through battery storage systems developed for grid infrastructure, transportation and industrial applications. Its platforms combine lithium-ion cells, battery management technology and software controls within a coordinated framework designed around real usage conditions.

Instead of treating storage as an isolated asset, it aligns battery behavior with charging patterns, grid response requirements and long-duration performance expectations. That approach has supported projects across utility-scale storage, marine electrification and electric transit networks.

Integrating Storage Into Utility Infrastructure

Renewable energy sources do not always generate electricity when demand peaks. Sudden changes in solar or wind output can place pressure on traditional power infrastructure that was not built for rapid balancing adjustments. Leclanché addresses those gaps through battery energy storage systems configured for frequency regulation, peak demand management and renewable energy shifting across utility networks. Operators can store excess energy during lower-demand periods and release it when grid conditions tighten.

Europe's Battery Storage Market Moves Toward Intelligent Energy Infrastructure

Battery storage solutions have become one of the most important segments in Europe’s energy economy. What began as a support technology for renewable energy projects is now evolving into a central component of modern power infrastructure. Utilities, manufacturers, logistics providers, transport operators and data centre companies increasingly rely on battery storage systems to improve energy reliability and manage electricity costs.

Europe’s clean energy transition has accelerated demand for flexible energy infrastructure. Solar and wind generation continue to expand across the region, yet intermittent supply patterns have exposed weaknesses in traditional grids. Battery storage solutions help stabilise the electricity supply by storing surplus energy and distributing it during periods of peak demand or reduced generation.

Recent market indicators show strong momentum across the sector. Industry forecasts published during 2025 and 2026 project continued double-digit growth for Europe’s battery energy storage market. Germany, the UK, Italy and Nordic countries remain among the region’s largest investment markets due to strong renewable energy deployment and grid flexibility requirements.

The International Energy Agency reported that battery prices continued to decline globally during 2025. Lower system costs are improving the financial case for large-scale storage deployments across commercial and industrial sectors. Enterprises that previously viewed storage infrastructure as prohibitively expensive are now reconsidering investment timelines and deployment strategies.

Renewable energy expansion has become one of the strongest market drivers. Europe’s solar generation capacity has increased rapidly, particularly in Germany and Southern Europe. Periods of excess daytime power generation have created pressure on electricity markets and grid balancing systems. Battery storage platforms increasingly absorb surplus electricity and release it during higher-demand periods.

Energy price volatility has also changed enterprise buying behaviour. Manufacturers and industrial operators across Europe continue to face uncertainty linked to wholesale electricity pricing and long-term energy security. Battery storage systems offer businesses greater control over consumption patterns while supporting resilience during supply disruptions.

Data centres represent another major growth segment. Europe’s expansion of digital infrastructure has substantially increased electricity demand. Operators are investing in battery storage solutions to strengthen backup power capabilities, reduce reliance on diesel generators, and meet energy efficiency targets. Grid-connected storage systems also support participation in demand response programmes and energy balancing markets.

Transport electrification is contributing to broader market growth. Fleet operators, airports and public transport authorities increasingly require storage infrastructure capable of supporting electric vehicle charging networks and local power management. Battery storage systems can reduce strain on regional grids while improving charging reliability for large vehicle fleets.

A major trend shaping the market is the rise of co-located renewable energy and storage projects. Developers increasingly combine solar or wind assets with integrated battery systems to improve energy management and strengthen commercial returns. Research published during 2026 projected that Europe’s co-located renewable and storage capacity could increase sharply by the end of the decade.

The competitive landscape is also evolving. Early battery storage providers focused heavily on hardware supply and installation services. Mature battery storage solutions companies now compete through software intelligence, energy forecasting, grid integration expertise and lifecycle management capabilities. Enterprise buyers increasingly prioritise providers that can deliver advanced monitoring, predictive maintenance and automated energy optimisation.

Digital capabilities are becoming more important as battery systems connect more deeply with enterprise infrastructure. Smart energy management platforms can now analyse demand patterns, optimise charging cycles and support participation in electricity trading markets. Artificial intelligence and predictive analytics are improving how storage assets respond to fluctuations in grid demand and renewable energy generation.

Despite strong growth prospects, several structural barriers continue to affect deployment timelines. Grid connection delays remain a major challenge across several European markets. Permitting complexity, ageing infrastructure and inconsistent regulatory frameworks can slow project approvals and increase development costs.

Supply chain dependence remains another concern for policymakers and enterprise buyers. Much of the global battery manufacturing ecosystem remains concentrated in Asia, particularly for lithium-ion technologies. European governments and industrial groups continue to invest in regional battery production capacity to reduce long-term dependence on overseas suppliers and strengthen energy security.

Technology diversification is beginning to shape the next stage of market competition. Lithium-ion batteries continue to dominate most deployments, yet interest in sodium-ion batteries, long-duration storage systems and hybrid energy platforms is increasing. Enterprise buyers are paying closer attention to lifecycle economics, recycling capabilities, thermal management and environmental impact rather than focusing solely on storage capacity.

The market is also entering a more mature phase from a regulatory perspective. European policymakers increasingly recognise battery storage as critical infrastructure, directly linked to decarbonisation goals and industrial competitiveness. Regulatory frameworks continue to evolve around grid participation, electricity trading and storage incentives, though implementation still varies across member states.

Battery storage solutions are no longer viewed as niche energy assets. They are becoming essential infrastructure for a more electrified and decentralised economy. Enterprises evaluating the category now expect storage systems to support energy resilience, sustainability targets and long-term cost control simultaneously.

Europe’s battery storage market will likely move toward greater intelligence, automation and integration during the next decade. Storage systems are becoming part of wider digital energy ecosystems that connect renewable generation, electric transport infrastructure, industrial facilities and smart grids. Enterprises investing in the category are increasingly focused on scalability, flexibility and long-term infrastructure value rather than short-term deployment alone.

Delphy Underground Storage System: The Right Fit for Green Hydrogen Market Needs
Vincent Designolle, Director of Delphy Hydrogen Storage

Through this article, Designolle emphasizes the critical role of safe, scalable hydrogen storage solutions like Vallourec’s Delphy vertical underground system in enabling the reliable integration of hydrogen into the renewable energy mix and supporting the global energy transition.

Hydrogen is becoming an increasingly important part of the renewable energy mix. From production to end use, safe hydrogen storage is needed to ensure a reliable supply along the value chain. Vetted and tested for commercialization, Vallourec’s Delphy underground vertical storage system provides a scalable solution with a capacity range from one to 100 metric tons.

There are promising signs worldwide that hydrogen will play a big role in the energy transition. The Hydrogen Council recently reported a 90 percent increase in investment in projects that passed the final investment decision (FID) in 2024 compared to 2023. This represents a cumulative 4.6 Mt p.a. of clean capacity past FID (up 53 percent from 2023). The positive upswing is partially due to supportive policies and action plans being designed and implemented globally. In February 2025, the European Commission notably published its strategy to foster its regulatory framework and investment program for low-emissions hydrogen production.

This decarbonization journey involves green hydrogen development, utilizing renewable energy to power the electrolysis process. However, renewable energy, such as solar and wind, only offers intermittent hydrogen production through electrolysis. In contrast, hydrogen end users need a continuous and reliable supply for processes like refining ammonia and e-fuel production. To manage intermittent production and effectively integrate hydrogen into a future decarbonized energy mix, large-scale hydrogen storage is the key.

What is Vertical Hydrogen Storage?

Until recently, hydrogen storage was limited to small-capacity cylinders or bullet tanks holding up to one metric ton or vast spaces like salt caverns, offering up to 10,000 metric tons of storage capacity. Vertical underground hydrogen storage, such as Vallourec’s Delphy solution, fills the gap, providing a viable, secure and scalable option for onsite storage from one to 100 metric tons.

“Vallourec partnered with third-party certification expert DNV to accompany its technology qualification process according to DNV’s Recommended Practice RP A203. This process addresses all potential risks and tests and validates the technology’s entire storage system architecture.”

Leveraging Vallourec’s 50-plus years of metallurgical expertise, the pressure vessels are designed using special alloys that resist hydrogen embrittlement. Vallourec’s range of hydrogen-proof premium connections ensures a tight system assembly.

Vertical storage offers a flexible solution that can be easily installed at facilities where surface area is at a premium. Delphy requires 30 times less acreage than an above-ground alternative. And because it is a modular solution, its storage capacity can be optimized according to project needs.

Focus on Safety

Delphy, above all, is a safe hydrogen storage system. Throughout its development process, safety has been at the forefront. Vallourec partnered with third-party certification expert DNV to accompany its technology qualification process according to DNV’s Recommended Practice RP A203. This process addresses all potential risks and tests and validates the technology’s entire storage system architecture. The qualification plan was defined (Statement of Endorsement reached in 2024) and testing took place on a demonstrator built at Vallourec’s research facilities in France. Vallourec and DNV are currently reviewing the test results, targeting a full technology qualification by mid-2025.

This follows a regulatory compliance assessment, specifically the European Pressure Equipment Directive (PED). In 2024, a third-party inspector reviewed the demonstrator’s design and manufacturing. After the pressure test, the inspector confirmed compliance with the PED—a mandatory step before Delphy can be put on the market.

The system’s intrinsic safety comes from the pressure vessels’ design, subsurface geometry, and passive safety features implemented in the design. Its state-of-the-art instrumentation and automation provide further safety assurance, with various detection systems that react to potential leaks or hazardous events.

Vallourec joined with experts from third-party classifier Bureau Veritas to perform a comparative quantitative risk assessment. The test concluded that Delphy’s safety perimeters are half of what equivalent above-ground options need to ensure safe distance. This benefit is a strong asset in easing integration into industrial sites and during the permitting process.

Delphy Storage Unlocks Value: Case Study for Green Ammonia Projects

Italian technology and engineering group NEXTCHEM (part of the MAIRE group) and Vallourec assessed the integration of Delphy storage into hydrogen and green ammonia production projects around the world. They ran a case study on a typical project and compared several scenarios. The study determined that integrating Delphy hydrogen storage with green ammonia production could significantly reduce the levelised ammonia (LCOA) cost by up to 15 percent.

Accelerating Toward Commercialisation

With technology validation well underway, Vallourec stands ready to support hydrogen market development worldwide. It is targeting Delphy’s first commercialisation in 2025 as part of its strong ambitions to develop its businesses in New Energy sectors.
