In early 2026 Croatian engineering firm Inovapro announced plans for the country's first green AI data centre near Trilj, powered by biomass from olive-industry waste and supported by solar drying technology. The €20 million, 3 MW facility is scheduled for completion in the first half of 2027 and is positioned as a model for the region.
For the broader European market the project highlights two truths. First, sustainability in data centres is moving beyond renewable purchase agreements to genuine local resource integration. Second, even innovative power solutions succeed or fail on execution quality.
The delivery challenge is universal
At HAT Solutions we see the same pattern in every energy and infrastructure programme: the most promising technology still requires rigorous feasibility work, interface coordination, supply-chain discipline and structured commissioning. Whether the energy source is biomass, nuclear restart, geothermal or a hybrid renewable portfolio, the delivery challenge is identical — turn concept into reliable, documented performance on the ground.
Clients who apply our scheduling toolkit and decision framework from day one consistently deliver projects with fewer change orders, smoother handovers and facilities that meet both commercial and environmental targets.
Small in scale, significant in ambition
Croatia's project is small in global terms but significant in ambition. It shows that Europe can develop data-centre capacity that is both AI-capable and genuinely sustainable — provided the execution system around the technology is as thoughtful as the technology itself.
The next wave of European data-centre builds will test many delivery teams. Those who combine innovative energy strategies with disciplined, owner-minded project execution will be best positioned to meet the demands of the AI era while staying aligned with Europe's climate goals.
