From Batteries to Molecules: Why Europe’s Storage Shift Opens a Strategic Window for Hydrogen in Latvia
A new EU report shows that energy storage in Europe is scaling fast, with batteries leading near-term deployment and hydrogen gaining relevance in longer-duration flexibility. For Latvia, this creates a clear strategic opening to link renewable hydrogen, power system balancing and the next phase of the Baltic energy transition.

Europe’s power transition is entering a more mature phase. The latest Joint Research Centre report shows that energy storage is no longer a side topic in the clean energy debate, but a core part of how Europe plans to integrate more renewables, strengthen grid stability and improve energy security. Across Europe, 2,356 energy storage projects have been identified, representing 170.92 GW of combined power, with 70 GW already operational and 97.26 GW expected online by 2030.
For Latvian Hydrogen Alliance, the message is important. The storage market is expanding rapidly, but it is not moving in one single technological direction. Europe is building a layered flexibility system, and that creates space for renewable hydrogen to play a more defined and more valuable role.
Energy Storage Becomes Core Energy Infrastructure
The report confirms that storage is now central to the European energy system. It supports renewable energy integration, contributes to grid stability and improves the security and quality of supply. In other words, storage is becoming essential infrastructure for a zero-carbon power system rather than an optional add-on.
That scale-up is already visible in the numbers. Pumped-storage hydropower still dominates operational installed power, while batteries are clearly leading the next wave of deployment. The JRC notes that mechanical storage accounts for 53.94 GW of operational power, while electrochemical storage accounts for 13.9 GW. But for expected new capacity, the picture changes sharply: electrochemical storage reaches 84.72 GW, far ahead of mechanical storage at 6.96 GW.
This is the clearest signal in the report for investors and policymakers alike. Europe is moving from legacy storage assets toward a much larger base of flexible, fast-response systems designed to support solar and wind growth at scale.
Hydrogen Finds Its Place in the Flexibility Stack
For the hydrogen sector, the most relevant insight is not that batteries are winning. It is that the market is becoming more segmented, and that hydrogen has a clearer role within that structure. The report distinguishes short-duration storage, typically up to eight hours, from long-duration storage that can operate across longer periods, including days, weeks or even seasons. It also classifies hydrogen under chemical energy storage through power-to-gas.
That matters because renewable hydrogen should not be judged against batteries on the same terms. Batteries are highly effective for rapid balancing and shorter discharge cycles. Hydrogen becomes more strategic where the system needs deeper flexibility, sector coupling and energy storage beyond the short-duration range. This is an inference from the report’s technology classification and duration framework, but it is a practical one for the Baltic energy market.
The report also shows that hydrogen is already present in Europe’s storage landscape, even if it remains at an earlier stage than batteries. According to the JRC, Europe has 64 operational power-to-gas hydrogen projects and 39 more expected. That is not yet a dominant market segment, but it is enough to show that hydrogen storage is moving from concept to implementation.
EU Policy Is Making Storage More Investable
The policy direction is also becoming more concrete. The report highlights several regulatory drivers that will shape investment decisions in storage across the EU. Among the most important are mandatory flexibility assessments by transmission system operators by 2026, the requirement for Member States to define indicative national objectives for non-fossil flexibility, and the battery passport requirement by 2027 for batteries above 2 kWh.
At the same time, the report makes clear that implementation across Europe is still uneven. Only 6 Member States include explicit energy storage targets in their national energy and climate plans, while 17 include storage-related policies without setting specific targets. That means Europe has moved decisively into the storage build-out phase, but the policy environment is still developing country by country.
For emerging hydrogen markets, that is not a weakness. It is a window. Countries that move early to define the role of renewable hydrogen in flexibility, industry and balancing can still shape their market position before the European landscape becomes more crowded and more standardized. This point is an inference based on the report’s findings on policy momentum and unequal national progress.
Latvia’s Strategic Opening in Renewable Hydrogen
The report does not place Latvia among Europe’s leading storage markets today. But that is precisely why the Latvian opportunity should be read strategically rather than statistically. Europe’s storage market is still being formed, and the strongest positions will not be built only by scale. They will be built by relevance to future system needs.
For Latvia, that means focusing on the part of the energy transition where renewable hydrogen can offer distinct value. As more wind and solar enter Baltic electricity systems, the need for flexibility will grow. Batteries will cover an important share of short-term balancing, but renewable hydrogen can support the harder layer of the transition: longer-duration flexibility, conversion of surplus renewable electricity, industrial decarbonisation, and future integration between power, transport and fuel markets. This Latvia angle is an inference from the report’s analysis of storage technologies, services and market direction.
That is where the case for renewable hydrogen in Latvia becomes stronger. Not as a generic alternative to batteries, and not as a distant future option, but as a strategic complement in a more flexible Baltic energy system. Europe is scaling energy storage fast. Latvia now has a credible opportunity to position hydrogen where it can create the most value: at the intersection of green electricity, energy security and long-term system resilience.
