Introduction
The energy transition has become a strategic priority for Europe while being a recurring theme in political and economic debates. Accelerated by external shocks, from the war in Ukraine to the blackout in Portugal, the continent's vulnerability to external energy dependencies pushed Europe to pursue greater energy sovereignty.
The transition marks the shift from a system based on fossil fuels to one that prioritizes renewable sources such as wind, solar, and hydropower. More broadly, it concerns how energy is produced, distributed, and consumed. Despite progress, fossil fuels still represent around 80% of the global energy mix, underlining how far there is to go. In heat alone, which accounts for nearly half of total final energy consumption, only about 12% of industrial heat currently comes from renewables, a share expected to reach just 15% by 2028 (IEA 2024).
Nonetheless, the momentum is undeniable: in 2024, Europe generated more than 50% of its electricity from renewables, mainly wind and solar, for the first time ever.
At the heart of this transformation stand three interconnected pillars that will determine the pace and resilience of the energy transition:
The virtuous flywheel
These pillars form a synergistic system, not three isolated trends.
These pillars evolve into a virtuous flywheel: each innovation amplifies the impact of the others. Renewables supply cheap power, storage ensures temporal balance, and flexible industrial demand stabilizes the system.
Solutions such as Energy Dome demonstrate this dynamic, unlocking long-duration storage through its CO₂-based pumped-thermal technology, and Sinergy Flow that develops a sustainable redox-flow battery enabling cost-efficient medium-duration storage. NOC Energy deploys high-temperature modules that electrify industrial heat and store thermal energy at scale. On the flexibility side, Enspired is orchestrating distributed energy assets in real time across European power markets, turning flexibility into a tradable resource.
Roadblocks on the path to Net-Zero
Europe's commitment to net zero by 2050 comes with ambitious policies: European Green Deal, Net-Zero Industry Act and RePowerEU. Beyond policy, market forces are now accelerating the shift. Energy demand continues to rise, driven by data centers, electric vehicles, heat pumps, and industrial reshoring. Electricity's share of final energy consumption is set to increase from 21% today to 27% by 2030 (IEA NZE Scenario), which reflects the growing electrification of industry and households.
The storage and flexibility solutions are beginning to scale: on one hand, over 35 GW of new demand-response capacity is expected in Europe by 2030; on the other, grid-scale battery installations continue to grow. According to the WEF (2025), grid flexibility "maximizes renewable integration, stabilizes energy costs, and guards against climate-related risks."
Still, a coordination gap remains. Supply, demand, and storage often operate in silos, limiting system efficiency. Integration, here, means more than co-locating technologies, but connecting physical assets, digital coordination, and market participation into one interoperable system capable of monetizing flexibility and balancing the grid.
At the same time, this system operates within the limits of Europe's electricity grid: transmission bottlenecks, slow permitting, and uneven cross-border flows still constrain renewable integration. The IEA estimates that the global grid length must grow by 20%, as the annual investment must rise to US$600 billion per year by 2030 (up from US$300 billion today), to maintain system reliability.
Flexibility and storage can alleviate local congestion, but grid reinforcement and interconnection remain indispensable to achieve continent-wide balance.
Public policies provide direction, but execution now lies in private hands: startups, utilities, and industrial players capable of deploying hybrid, interoperable solutions at scale.
Building momentum & strategic opportunities
The IEA estimates that clean-energy innovation investment must triple by 2030 to stay on a net-zero pathway. That capital will increasingly flow toward systems that combine efficiency, electrification, and digital orchestration: exactly where this flywheel sits.
The Energy Taxation Directive revision tilts economics toward low-carbon heat and storage. In addition, the rise of DSO-level flexibility markets monetises demand response and on-site storage. This is reinforced by falling costs from learning curves in renewables, batteries, and power electronics that make integration increasingly profitable.
For founders, this is an open field for hybrid solutions that capture multiple value streams: energy, capacity, and carbon.
For the ecosystem, it's a call to turn flexibility into a standard market product, not a regulatory afterthought.
For investors, it's a signal to back stackable business models that operate across this loop, converting volatility into stable, diversified returns.
This flywheel, embodied by solutions like Energy Dome, Sinergy Flow, Enspired and NOC Energy, is where Europe's next climate-tech champions will emerge.
Conclusion
At 360 Capital, we see the energy transition not as a linear substitution of technologies, but as a systemic reconfiguration where power, heat, and flexibility converge into a single market logic.
The three pillars we explored, industrial heating, long-duration energy storage, and energy flexibility — are now forming a flywheel: as each one scales, it strengthens the economics of the others. This is where the real innovation lies: in integration.
The opportunity ahead is to build platforms that blur the boundaries between production and consumption, storage and dispatch, industry and grid.
