FerroBAT

Challenge:

The maritime sector is facing a major transition from fossil fuels to fuels based on renewable energy sources in the coming years. However, there is still a need to find solutions to store renewable energy. Energy storage will play a key role in the green transition as it will enable a more stable and reliable integration of renewable energy sources such as solar and wind into the existing electricity grid.

Solution:

The project aims to develop an innovative energy storage solution based on Iron Flow technology that can provide reliable long-term energy to maritime vessels and the grid using non-toxic, environmentally friendly, cost-effective and non-combustible iron-based electrolytes. Innovation in the use of water-soluble iron coordination complexes will allow operation at neutral pH. This will represent a major non-iterative step that will bypass energy losses and the need to rebalance cells as a consequence of coating and hydrogen circulation. This will favourably simplify stack construction considerably.

Extensive test trials will be performed on a large-scale commercially available iron flow battery (75 kW / 500 kWh) to obtain a great understanding of the system and improve battery operation. In addition, a control strategy for effective operation (efficiency and reliability) will be developed.

Effect:

The project aims to attain a <100 €/kWh cost for the flow battery upon scaling-up.
