VisBlue maintains close ties with the academic community, providing us with valuable insight into the development of redox flow technology. Here, you can learn more about the projects we are currently involved in and the findings emerging from this research.
Organic Redox Flow Battery Systems, referred to as ORBATS, is an ambitious project focused on optimising energy storage in terms of cost, efficiency, and reducing its environmental impact. With ORBATS, the goal is to develop redox flow battery technology using a non-corrosive organic electrolyte with improved solubility. Together with Vestas, Aarhus University, DTU Energy, Harvard University and Lithium Balance, VisBlue has initiated this project with the objective of advancing solutions in this field. However, the technology is still at the research and developement stage, meaning it will take a few years before it becomes commercially available.
This project aims to educate young students and school pupils about the intelligent energy grids of the future, and how our technology can serve as a tool to help make this a reality.
At VisBlue, we continuously strive to optimise both our products and our business. One of our current focus areas is developing a more circular business model that benefits our customers, VisBlue, and the environment. By taking these factors into account, we make it easier for our customers so they don’t have to.VisBlue has been awarded EU funding to initiate our own ‘RethinkBusiness’ project. As part of this support, we have also been assigned an external consultant to help define how we can implement ‘Cradle to Cradle’ principles in our business.

This project aims to support, develop, and improve the commercial production of a Danish vanadium redox flow battery (VRFB) and energy storage solutions with quality assurance. VisBlue achieves this by testing, optimising, and demonstrating the interaction between VRFB technology and solar installations, water heating systems, and heat pumps. In addition, the project aims to demonstrate the potential of VRFB technology as a buffer in the electricity grid within an increasingly decentralised energy system.
This project aims to improve a digital interface solution to prepare the market for a Danish-produced vanadium redox flow battery (VRFB) system. The project seeks to optimise an independent digital service product that enhances communication between the VRFB system, solar installations, the electricity grid, and the end user.
In collaboration with EUDP, Eniig, and Aarhus University, VisBlue is involved in the project Grid Connected Flow Batteries, which aims to eliminate undesirable fluctuations in a local energy grid in a residential area equipped with rooftop solar panels. This is achieved by installing a vanadium redox flow battery next to the transformer station. The flow battery acts as a grid buffer for excess energy generated by the solar installations, thereby stabilising voltage and reducing strain on the electricity grid. Buildings connected to this transformer station will also benefit from improved utilisation of the solar panels’ optimal output

Innovative technological solutions for energy storage in chemical and electrochemical forms play a key role in achieving this goal. With a total investment of EUR 8,145,027.00, the project is co-financed under the P2020 | COMPETE – Projects Mobilisers Program, with EUR 5,325,434.81 provided by the European Regional Development Fund (ERDF). The Baterias 2030 project, led by DST Solar, S.A., will be carried out by a consortium of 23 partners, including 14 companies and 9 entities from the Portuguese National R&I System, ensuring the effective and successful delivery of both the technical-scientific and economic/commercial objectives of the project.

The BluEnergy project aims to develop the next generation of redox flow battery (RFB) technology for stationary applications, at low cost, for storing electricity from renewable energy sources. With a total investment of EUR 1,174,334.80, the project is co-financed under the P2020 | COMPETE – Projects in Copromotion Program, with EUR 704,096.18 provided by the European Regional Development Fund (ERDF). The BluEnergy project runs over a three-year period, from June 2020 to June 2023, with Simoldes Plásticos, S.A. as the lead partner, and VisBlue Portugal and the University of Porto as co-promoters.
