StoreMoreWarm

Europe is undergoing a historic energy transformation. To meet its climate targets under the European Green Deal, the EU has committed to reducing greenhouse gas emissions by at least 55% by 2030 and achieving climate neutrality by 2050. Legislative frameworks like the Fit for 55 package, REPowerEU, and the revised Energy Performance of Buildings Directive (EPBD) are pushing member states to accelerate renewable energy deployment, boost energy efficiency, and cut dependency on fossil fuels. 

Yet, with the rise of renewables like solar and wind, new challenges have emerged. These sources are clean—but variable. Energy is often generated when demand is low and wasted when it’s most needed. Storage has become the missing link in this new energy system. 

Buildings are at the center of Europe’s energy challenge. They account for approximately 40% of the EU's total energy consumption and 36% of its CO₂ emissions. The majority of Europe's building stock is inefficient, built before modern energy standards existed. A significant portion still relies on fossil-fuel-based heating, particularly natural gas. 

Despite this, buildings offer untapped potential: they could act as thermal energy buffers, helping store and redistribute heat more efficiently. Unlocking this potential requires innovation—and coordination across sectors.

StoreMoreWarm is a transnational project under the Interreg Danube Region Programme that responds to Europe’s most pressing energy and climate challenges. By exploring the current status of cutting-edge thermal energy storage (TES) solutions, we aim to transform buildings from passive energy consumers into active storage units. 

We focus on high-capacity, scalable technologies—such as alternative materials for sensible heat storage, phase change materials, and enhanced building components—to store more warmth when it’s available and release it when it’s needed. This doesn’t just reduce emissions—it strengthens energy resilience, lowers bills, and empowers communities. 

Join us in reshaping Europe’s energy future—one warm building at a time.
