Eliminating Dependency With 24/7 Renewables: Why Europe’s Energy Future Needs Storage Now

Europe’s energy policy is undergoing an acid test right now. The ongoing oil and gas crisis, geopolitical tensions and volatile prices have exposed the painful vulnerability of an energy system based on imported fossil fuels. At the same time, the electrification of industry, mobility and heating is rapidly driving up electricity demand. The key question is therefore no longer whether Europe will shift its energy supply, but how quickly and how resiliently this transition can succeed.
Renewable energies – especially the combination of solar energy and battery storage – provide a clear answer. This is precisely where the special exhibit Renewables 24/7 at the alliance of exhibitions The smarter E Europe comes in. The event will demonstrate that a secure, competitive and 24/7 fully renewable energy supply is already possible today.
The Solar+ study recently presented by SolarPower Europe underscores the strategic importance of this approach. According to the study, solar energy could become Europe’s main source of electricity by 2030, covering more than a quarter of the EU’s electricity demand. What we need now is not just an expansion of generation capacity, though, but its intelligent integration into the energy system. This is where battery storage comes in as the key technology that ensures supply security and price stability.
Battery storage will play a system-critical role going forward because it balances out fluctuations in solar and wind power, shifts electricity to periods of high demand, reduces grid expansion costs and lowers dependence on fossil-fuel peak load power plants. In the ambitious Solar+ scenario, the EU’s battery storage capacity will grow to nearly 600 gigawatt hours by 2030. Storage will thus evolve from an add-on to specific projects to infrastructure elements for a renewable energy system.
The economic effects have the potential to be significant. The combined expansion of solar energy and storage can substantially reduce the European power system’s operating costs. What’s more, it will drastically reduce the demand for natural gas imports, making it an important lever for strengthening Europe’s geopolitical agency. Every cubic meter of gas that Europe no longer imports bolsters domestic value creation, reduces price risks and strengthens supply security.
The special exhibit Renewables 24/7 at The smarter E Europe 2026 will put these mechanisms within reach. Visitors will be able to see power generation, storage, flexibilization and digitalization intelligently work together across four thematic areas: industry, commerce, residential applications and mobility. Best-practice examples from all over Europe debunk the myth of “unreliable renewables” by showing that smart storage, digital grids and sector coupling make a stable energy supply achievable – even without oil and gas.
For Europe, and especially for emerging energy markets like Romania, the message is clear: The future of energy is renewable, decentralized and storage-based. Investing into battery storage and integrated solutions now not only protects the climate, but also ensures competitiveness and energy independence. The smarter E Europe, Europe’s largest alliance of exhibitions for the energy industry, will take place from Tuesday, June 23 to Thursday, June 25, 2026, at Messe München and will bring together around 2,800 exhibitors and over 100,000 trade visitors from around the world.
