Spanish startups lead innovation in renewable energy


Spain is strongly committed to renewable energy and the fight against climate change. Our country is one of the signatories of the Paris Agreement of 2015. Also, we have our own Spanish Climate Change and Clean Energy Strategy (EECCEL), and we have implemented two Energy Saving and Efficiency Action Plans, as well as a National Allocation Plan for Compliance with the Kyoto Protocol.

Spanish startups are making valuable contributions to curbing environmental pollution and cutting down on greenhouse gas emissions, as they are playing an increasingly important role in the development of clean technologies.

This becomes apparent in two areas: renewable energy and water management. Several Spanish startups have got support from big energy firms or the European Union to do research and develop their eco-friendly products.

Hydrogen as energy

Bound4blue is working on a unique renewable energy system for large vessels, invented and patented in Europe, USA, China and Japan by José Miguel Bermúdez and Jordi Sala, aerospace engineers from The School of Industrial, Aerospace and Audiovisual Engineering of Terrassa (ESEIAAT) at Universitat Politècnica de Catalunya.

It consists in the production of hydrogen and oxygen by means of electrolysis of seawater. The vessel is propelled by wind-driven wingsails, as water fills the ship’s turbines to produce mechanical energy, then transformed into electrical energy.

Photovoltaic glass

Onyx Solar is a global leader in photovoltaic (PV) glass for buildings. Replacing conventional glass, PV glass enables the conversion of light into electricity by incorporating transparent semiconductor-based photovoltaic cells. This cost-effective technology reduces CO2 emissions.

Wind power efficiency

Another Spanish startup, Smartive, has developed a revolutionary wind turbine optimisation software tool: CloudDiagnosis. It is a cloud-based technology for wind farm data collection, so that operators can review the status of their wind turbines.

Users can easily access wind power data on their mobile devices, diagnosing turbine failures and performance issues in real time, and making forecasts for three weeks.

International consultants

Another leading Spanish startup, Factor CO2 provides advice and support to companies and organisations from around the world, helping them attain their goals in the fight against climate change by implementing measures to reduce gas emissions and make carbon sinks more effective.

Established in 2004, Factor CO2 has grown into a global corporation offering solutions to fight climate change. It has participated in international projects, like the implementation of a carbon footprint calculator for nine products in 18 companies in Ecuador.
