H2 Inc. Secures Landmark 8.8MWh Vanadium Flow Battery Project in Spain
September 2, 2024 - H2 Inc. announced today that it has been awarded a project to deploy a 1.1MW/8.8MWh vanadium flow battery (VFB) system in Spain, marking the largest VFB initiative in the country to date. This landmark project, commissioned by Spain's energy research institute CIUDEN under the Spanish Ministry for Ecological Transition and Demographic Challenge, aims to provide a long-duration energy storage solution capable of delivering maximum power for up to 8 hours.
H2 Inc., in collaboration with local Spanish companies, successfully secured the bid and will supply the entire battery system, central to the project's success. The project will utilize H2’s newly developed modular flow battery, the EnerFLOW 640. Vanadium flow batteries, such as the EnerFLOW 640, offer several advantages over traditional lithium-ion batteries, including superior fire safety, a longer lifespan with minimal degradation over 25 years, and enhanced environmental benefits due to the recyclability and reusability of vanadium electrolytes.
The EnerFLOW 640 represents a significant advancement in VFB technology, featuring the smallest footprint ever achieved for such systems, thanks to H2’s innovative high-performance stacks, a unique three-block design, and HyperBOOST technology. The project is set to be completed within 16 months, with installation scheduled for the second half of 2025.
Spain is at the forefront of the energy transition in Europe, with a goal of generating over 80% of its energy from renewable sources by 2030 as part of its net-zero targets. As part of its strategy to ensure a stable power supply, Spain aims to install 20GW of energy storage capacity, selecting vanadium flow batteries for their superior long-duration storage capabilities. This growing global demand for large-scale Long-Duration Energy Storage (LDES) solutions underscores the critical role of VFB technology in mitigating climate change and achieving carbon neutrality.
With a production capacity exceeding 330 MWh in South Korea and proprietary flow battery technology developed in-house, H2 Inc. is poised to expand its footprint in the European LDES market, using Spain as a gateway. This project also complements H2's ongoing 20MWh project in California, strengthening its market position in both the U.S. and Europe.
Dr. Shin Han, founder and CEO of H2 Inc., commented on the announcement, stating, "Large-scale LDES systems are rapidly becoming essential technologies in the fight against global warming and the drive towards carbon neutrality, with vanadium flow batteries playing a central role in this transformation. This project in Spain is another testament to H2's leadership in the global LDES market through our cutting-edge flow batteries. We will continue to expand the global deployment of our batteries, leveraging our significantly increased production capacity. Additionally, H2 plans to establish a second VFB manufacturing facility in South Korea, aiming for gigawatt-hour scale production, which will enable even more global projects utilizing our state-of-the-art flow batteries."
