Invinity Enters Hungarian Market with Solar Battery Project
Invinity Energy Systems has announced its entry into the Hungarian market with the sale of a 0.9 MWh vanadium flow battery to a local solar developer. This project, the company’s first in Hungary, marks a key step in its strategy to expand its reach across Central and Eastern Europe.
The vanadium flow battery will play a crucial role in stabilizing the output of a 4.5 MW solar plant, mitigating the challenges of intermittent solar generation. With a four-hour storage duration, the battery will ensure a more consistent energy supply, particularly during peak demand, and enhance the solar facility’s overall reliability.
The project is supported by Hungarian government grants designed to encourage the adoption of energy storage solutions. This funding highlights the government’s commitment to fostering renewable energy and ensuring grid stability.
Strategic Expansion in Central and Eastern Europe
This sale marks a significant step in Invinity’s ongoing expansion within Central and Eastern Europe. The company previously partnered with Masdar, a renewable energy developer based in Abu Dhabi, to deploy a 5 MWh battery in Uzbekistan designed to bolster the grid in Bukhara, highlighting its commitment to delivering advanced energy storage solutions to emerging markets.
According to Kristian Egeberg, CEO of Invinity, there is substantial interest in vanadium flow batteries throughout Central and Eastern Europe. He emphasized that Hungary is at the forefront of deploying energy storage systems to support its burgeoning renewable energy sector.
With Hungary’s solar capacity projected to surpass 8 GW by mid-2025, according to PVKnowhow, Egeberg noted that Invinity’s batteries are particularly well-suited for these applications, offering reliable and long-duration energy storage. Invinity aims to leverage its expertise to capitalize on the increasing demand for energy storage in markets transitioning to renewables. Establishing a presence in Hungary strategically positions the company to address the region’s growing need for enhanced grid stability and seamless renewable energy integration.
Invinity’s Role in Hungary’s Renewable Energy Transition
Invinity’s vanadium flow batteries are engineered for long-duration energy storage, an essential component for integrating variable renewable sources like solar and wind into the grid. Unlike lithium-ion batteries, which are typically better suited for shorter durations, vanadium flow batteries can store and discharge energy for extended periods. This capability makes them ideal for managing the intermittent nature of renewable power generation.
The technology is also recognized for its durability and minimal degradation, ensuring efficient operation over many years without significant capacity loss. This makes vanadium flow batteries a cost-effective and reliable option for utilities and developers seeking long-term investments in energy storage infrastructure.
As countries like Hungary continue to increase their renewable energy capacity, the demand for dependable storage solutions will continue to rise. Invinity’s vanadium flow batteries are well-placed to meet this demand, offering a critical tool for stabilizing grids and ensuring a consistent supply of clean energy. Hungary has already achieved a 25% generation from solar energy, according to PVKnowhow, showcasing the nation’s commitment to renewables.
Invinity’s entry into the Hungarian market marks a pivotal moment in the company’s expansion into Central and Eastern Europe. Supported by government incentives and increasing demand for energy storage, Invinity is poised to play a vital role in facilitating the region’s transition to a sustainable energy future.
