BackAfter some years defined by caution, Europe’s infrastructure market is entering a more consequential phase. Capital remains selective, underwriting assumptions are tighter, and execution risk remains real. But across energy, digital and circular infrastructure, investors are placing greater emphasis on scale and delivery capability.
What 2026 may ultimately test is not investor appetite, but Europe’s ability to turn technological maturity and market momentum into assets that are built, connected and operational at scale.
Battery storage grows up
The shift from momentum to execution is clearly visible in Europe’s energy system. If one sector captured investor attention in 2025, it was battery storage. But by 2026, the conversation is moving from momentum to maturity.
“The next phase of BESS growth will be defined by how projects make money,” says Guillaume Rivron, Managing Partner at Marguerite. “We’re moving beyond a market dominated by ancillary services.”
As renewable penetration increases, batteries are being asked to do more: arbitrage price volatility, support grid resilience, and increasingly operate alongside generation assets. Scale and duration are rising, and so is complexity.
“Two-to four-hour systems are becoming the norm,” Rivron explains. “And larger projects are racing to capture value before returns normalise.”
The biggest swing factor for 2026, however, is regulatory.
“The treatment of negative electricity prices in renewables support schemes and the removal of penalties for BESS to withdraw energy from the grid are the two most important unresolved issues,” he says. “Fix that, and hybridisation of BESS with renewables suddenly becomes far more attractive.”
At the same time, Rivron cautions against simplistic assumptions.
“BESS is not plug-and-play. Strategies that work in one country don’t automatically work in another. The learning curve is steep, and it matters.”
Data centres: execution becomes the differentiator
Few markets feel as supply-constrained – and execution-sensitive – as data centres. AI and high-density computing are driving demand across Europe, but not all regions are equally positioned to respond.
According to Michael Dedieu, Managing Partner at Marguerite, the Nordics stand out because of fundamentals that are difficult to replicate elsewhere.
“Low-cost, low-carbon power at scale is the defining advantage,” he says. “It’s what allows the region to support energy-intensive AI workloads while meeting sustainability expectations.”
By 2026, however, access to demand will not be the bottleneck. Delivery will.
“What really differentiates platforms now is speed to market and technical readiness,” Dedieu argues. “Power secured, land permitted, cooling solutions proven – that’s what converts capex into cash flow.”
Sustainability is no longer a secondary consideration.
“Energy efficiency and heat reuse are increasingly part of procurement decisions,” he adds. “They’re not optional extras.”
Circular economy: from intent to infrastructure
The circular economy has long been framed as a necessity. What is changing is its investability.
“We’re moving from principle to implementation,” says Pilar Gomez, Managing Partner at Marguerite. “Regulation, resource scarcity and economics are finally aligning.”
Plastic recycling sits at the centre of that shift. While reducing consumption remains a long-term objective, near-term solutions focus on managing existing waste streams.
“Changing consumer behaviour takes time,” Gomez notes. “In the meantime, we need better collection, sorting and recycling technologies to preserve value and reduce environmental impact.”
EU targets for recycled content are accelerating demand – and investment.
“Mandatory recycling requirements are creating real market pull,” she says. “By 2026, we expect scalable industrial solutions to attract increasing capital.”
Growth, but with discipline
The common thread across all these themes is that investors are still willing to fund growth, but only where risk is understood, managed, and progressively reduced.
Rather than a sharp divide between core-plus and value-add, the market is converging around a more pragmatic model – building tomorrow’s core assets through disciplined expansion, development and capex deployment.
For Europe, 2026 could mark a turning point. Not because the challenges disappear, but because the ingredients are finally in place to address them. The question is whether execution – by policymakers, investors and operators alike – keeps pace with ambition.
