High electricity prices and the lowering costs of renewable technologies and energy storage are leading European energy consumers towards a distributed generation and self-consumption model. Electricity consumers are progressively turning into prosumers (producers & consumers) who decide at a given moment whether to buy electricity from the grid, to self-consume or even to export it to the grid. Moreover, European energy regulations require EU consumers to commit to clean and energy efficient objectives. For instance, the Energy Performance of Buildings Directive requires all new buildings to be nearly zero-energy (NZEB) by the end of 2020 by reducing energy consumption and using renewable sources and all new public buildings to be NZEB by 2018. The most extended renewable energy in the world is wind power. However, wind power is not very common in urban areas where high speed laminar wind turns into a low speed turbulent one due to the existence of obstacles (buildings, houses, trees, structures, etc.). Traditional wind power turbines are not designed to work with low speed wind (2 m/s – 6m/s) and turbulent wind flows. Besides, traditional SWTs entail other serious problems such as the hazard of rotating machinery, vibrations, noise, the possibility of collapse atop buildings, blade shedding and visual impact. EOLI FPS is a patented rooftop vertical axis wind turbine (VAWT) specifically designed to work under low speed and turbulent wind profiles such as the existing in urban environments. EOLIS FPS works perfectly with horizontal laminar wind but also take advantage of turbulent flows that adversely affect traditional wind turbines. Its internal rotor design facilitates the creation of vortexes out of the wind turbulence that drastically increases the driving force of the laminar wind. Besides EOLI FPS is safe, noiseless, does not vibrate and integrates aesthetically in the urban landscape.

Wind energy is the fastest growing renewable energy source in Europe, accounting for 10.2% of total electricity in 2015, however there is still a need to reduce the overall cost of energy – CoE to increase its competitiveness. The capital costs represents 78% of CoE and can be broken down into several categories, with around 54% attributable to wind turbine, from which the blades represents 30%. CoE can be reduced by maximizing energy production for the site by installing larger turbines. However, as the length of current rotor blades increase, their associated cost and weight increase at a faster rate than the turbine’s power output. Furthermore, as blades get longer they are becoming increasingly more difficult to manufacture and transport setting the limit at 90m. Winfoor (WF) and Marstrom (MC) aim to pursue this market opportunity by bringing to market its innovative and ground-breaking blade technology – Triblade. Triblade is a “3-in-1” modular blade, built as a Composite Material Truss that will allow rotor blades to be longer (up to 50%), stiffer (up to 290%) and lighter (up to 78%), whilst reducing around 65.2% production costs and increasing ease of transport and installation resulting in up to 15.5% CoE reduction. These are game changing improvements that can play an important role in driving the development of next generation of larger turbines and accelerate the transition to greater use of renewables worldwide. TRIBLADE project is expected to significantly enhance WF&MC’s profitability, with expected accumulated revenue of €85M and profits of €40M, 6 years after commercialization. Moreover, the successful achievement of TRIBLADE objectives is expected to assist Europe in achieving objectives to secure a sustainable energy system based on a low-carbon electricity from wind. This project will therefore entail increased competitiveness for the SME value chain and for the EU as a whole.
