Renewable Energy Innovation Center

ACCIONA applies Blockchain technology to verify that 100 % renewable energy is loaded into the power grid from two storage facilities in Navarra (Spain).

As part of the I'MNOVATION #Startups programme, ACCIONA has developed a pilot project for a commercial demonstrator, for the traceability of renewable sources of clean energy generated in Spain and by customers in Portugal, Mexico and Chile.

ACCIONA, through its commercial platform Greenchain®, applies Blockchain technology to certify the origin of the energy produced in its renewable generation plants, in real time and in a transparent way for its clients. This initiative was considered by the World Economic Forum (WEF) as exemplary and disruptive, and selected in 2020 as one of the most innovative solutions of the decade in the energy sector.

ACCIONA has two experimental battery-powered energy storage plants, one connected to a wind farm in Barásoain and another connected to a photovoltaic plant in Tudela, both in Spain. In both, grid integration technology has been developed with different functionalities such as: frequency regulation, voltage regulation, ramp control, arbitration and power guarantee accredited according to the GRIDSTOR procedure.

ACCIONA studies solutions for maximising the power curve by adopting control strategies in several turbine models operated by the company.

Within this scenario, we also are also working on the study, implementation and validation of noise reduction measures in wind turbines with different blade manufacturers.

The company has developed the manufacture of spare parts using 3D printing technology, thus avoiding technological obsolescence.

Turbine for Life

ACCIONA researches solutions to increase efficiency and extend the useful life of wind turbines under optimum safety and reliability conditions.

In this regard, the Turbine for Life programme develops a diagnosis of turbine status, provides predictive information on performance and offers recommendations regarding decisions about operation and maintenance.

ACCIONA has developed the WINDBRAIN® tool, using Big Data technology, Machine Learning and artificial intelligence.

This programme is also based on the application and use of physical and hybrid predictive models. Turbine for Life also helps to reduce operation and maintenance costs and extend the useful life of the wind turbines.

Thor
ACCIONA has implemented in Mexico a digital tool with artificial intelligence, THOR®, capable of predicting electrical storms, allowing decisions to be anticipated in order to make wind farms safer.

Power to Green Hydrogen Mallorca 

ACCIONA is researching the most efficient way to produce green hydrogen by using renewable energy sources as a renewable raw material in the industry, as a substitute for fossil fuels in the mobility sector and as part of the energy transition by helping reduce greenhouse gas emissions in the supply of natural gas.

This will make it possible to decarbonize a large number of processes currently being carried out in the island.

The company examines channels using 3D modelling technology for digitalisation and enhancements in security.

The company has developed an autonomous device (floating robot) capable of avoiding the deposition on the bottom sludge from the loading chambers of ACCIONA's Hydraulic Power Plants to avoid sedimentation and accumulation of sludge and therefore periodic cleaning that includes stopping the turbines, managing the sludge itself and the consequent labour and production losses.

ACCIONA has also manufactured the first active noise mitigation system prototype for hydroelectric plants, as a preliminary step to implementation at a real plant.
