EXPONENTIAL RENEWABLES SL

Their core work

X1 Wind (Exponential Renewables) is a Barcelona-based technology SME developing disruptive floating wind turbine platforms. Their core innovation centers on single point mooring systems and tension leg platform designs that reduce the cost and complexity of deploying offshore wind in deep waters. They have progressed from early-stage feasibility (SME Phase 1) through full-scale demonstration (PivotBuoy), designing mooring, connection, and installation systems purpose-built for floating offshore wind.

What they specialise in

How they've shifted over time

X1 Wind followed a textbook SME scale-up trajectory within H2020. They started in 2018 with a feasibility study (SME Phase 1, €50K) validating their disruptive floating wind concept, then secured a substantial RIA grant (PivotBuoy, €1.4M) to develop and demonstrate their mooring and connection system, and finally won an SME Phase 2 grant (€2.4M) to accelerate commercialization. Their technical focus sharpened from a general "disruptive floating wind" concept toward specific engineering challenges: mooring systems, tension leg platforms, and deep-water substructures.

X1 Wind is moving from R&D into market deployment of their floating wind platform, with growing focus on deeper water sites where conventional foundations cannot reach.

How they like to work

X1 Wind has coordinated all three of their H2020 projects, showing strong project leadership capability and confidence in driving consortia. Their network of 11 partners across 6 countries is moderate in size, suggesting they build focused consortia rather than sprawling ones. As a technology-originating SME that always leads, they are best approached as the central technology provider around which a consortium forms.

X1 Wind has built a network of 11 consortium partners across 6 European countries, centered from their Barcelona base. Their partnerships span the offshore wind supply chain, reflecting the multidisciplinary needs of floating platform development.

What sets them apart

X1 Wind is one of a small number of European SMEs developing proprietary floating wind platform technology from the ground up. Their single point mooring approach differentiates them from competitors using catenary or semi-submersible designs, potentially offering lighter, cheaper structures for deep-water deployment. Their complete SME Instrument journey (Phase 1 → RIA → Phase 2) demonstrates strong EU confidence in their technology's commercial viability.

Highlights from their portfolio

• PivotBuoy
  Their flagship technical project (€1.4M RIA) that developed and validated the core single point mooring and tension leg platform technology in real offshore conditions.
• X1 ACCELERATOR
  Largest grant (€2.4M SME Phase 2) focused on bringing their floating wind technology to market, signaling transition from research to commercialization.
