Concept

Throughout it’s extensive Research and Development phase, Crossflow employed the world leading advanced Computational Fluid Dynamics (CFD) capabilities Swansea University’s ZIENKIEWICZ CENTRE FOR COMPUTATIONAL ENGINEERING to model the complex air flow for the conceptual Crossflow turbine to identify the optimum blade and shield shapes required to maximise the greatly enhanced aerodynamic efficiency of the Crossflow Turbine and shield concept.

Validation

This analysis was validated using the full scale X-feg Proof of Concept turbine built using the CFD developed design incorporating the game changing patented rotor shield to enhance energy capture.

Extensive market research resulted in the decision to focus on continuous and reliable distributed energy supplies and the development, by combining Crossflow’s novel wind turbine with solar PV and battery storage of an Integrated Energy Solution (IES) offering reliable, clean energy as a viable and cost effective alternative to diesel generation in remote off/weak-grid locations; and developing an in-house Smart Energy Management system to optimise energy capture and ensure continuous clean energy output.

Proof

The Crossflow Pre-production Prototype (PPP) was successfully installed and commissioned as part of our SMART Turbine and SMART Modular system development at the company test site in Port Talbot, Wales. This PPP is used to gather operational data confirming energy capture and operational performance of both the turbine and Energy Management Software. In 2020, during the COVID crisis, Crossflow installed Phase 1 of a Smart Modular system unit to power a Digicel base station in the Caribbean. Phase 2 will commence in Spring 2021.

Evolution

In discussion with Mobile Network Operators, Crossflow have since repackaged the turbine layout design to incorporate a split-blade vertical hoist rotor, photovoltaic coated shield plus compact storage for batteries. This allows us to combine communications and clean energy generation in one structure on a much smaller footprint, with erection and maintenance at ground level
