The EU is testing energy storage solutions designed for industrial users and energy-intensive infrastructure through AGISTIN projects in the Cerglia-Sood Canal in Spain and the Netherlands. The aim is to reduce grid congestion, improve efficiency and enhance the flexibility of the energy system by integrating renewable electricity production with industrial consumption.
At present, with the accelerated integration of renewable energy into the economic system and the progress of economic electrification, the grid is facing increasing pressure. In this context, the EU AGISTIN project is advancing demonstrations aimed at connecting energy storage solutions with industrial users and energy-intensive infrastructure.
The initiative aims to build an integrated architecture based on DC-coupled technology to achieve synergy between energy storage, local generation and industrial consumption. The goal is to reduce operating costs, improve energy efficiency and enhance system flexibility to better balance renewable electricity production with industrial and commercial needs. The architecture proposed by the AGISTIN ensures that energy storage solutions are efficiently connected to local production and industrial consumption to effectively cope with fluctuations in energy flows and maximize the use of existing capacity.
The Spanish pilot project is located in the Ségría-Sud Canal, reports 2eu.brussels. The solution integrates a dedicated irrigation pump, a photovoltaic power station, a battery pack and a power converter. The system is designed to optimize irrigation efficiency and energy consumption, and provide grid flexibility services such as frequency modulation, voltage regulation and fault restart. Initial tests have verified the effectiveness of synchronous operation of each component, and subsequent data will help optimize the microgrid and troubleshoot hidden dangers before large-scale promotion. The core device uses an all-vanadium redox flow battery (VRF), which uses a liquid electrolyte to support independent capacity and power expansion. As a sustainable solution in line with the concept of circular economy, its electrolyte can be recycled.
The second demonstration in the Netherlands focused on green hydrogen production, integrating an electrolyzer, energy storage system, solar power and control platform. The project aims to reduce grid connection costs, extend equipment life and optimize performance, while suppressing power fluctuations affecting the electrolyzer. In addition, the project seeks to minimize the abandonment of renewable energy and enhance the grid's ability to accommodate local production. The demonstration covers laboratory and field tests on fast charging of electric vehicles, pumping station systems and industrial hydrogen applications, with a focus on the dynamic management of power fluctuations using energy storage solutions.
The project aims to develop control algorithms to coordinate these systems and explore business models that facilitate the integration of energy storage into the industrial sector. Through this demonstration, existing infrastructure such as irrigation systems can be transformed into flexible components of the energy system instead of serving only traditional functions; the deep integration of energy storage and hydrogen production can also help reduce emissions and improve grid resilience.
In summary, AGISTIN project demonstrates the huge potential of energy storage as an integral part of the energy system. The vision points to a more competitive economic model with a core focus on sustainability, energy efficiency and decarbonization.
