Allegro Energy pushes water-based battery storage for data centres
Allegro Energy has announced the application of its long duration energy storage technology for use in data centres aiming to address sustainability and reliability challenges.
Rising demand from artificial intelligence, cryptocurrency activities, and cloud services is contributing to increasing power requirements in data centres globally. This surge is accompanied by pressure to not only ensure supply reliability but also to decrease environmental impact and operational costs.
Demand growth
Energy requirements for data centres have reached new levels due to the expansion of digital workloads. Their operations typically require consistent, high-load power, with performance and uptime paramount for business continuity.
Allegro Energy is positioning its proprietary long duration energy storage (LDES) systems as a response to these needs. The technology uses a modular, water-based battery system designed for scalability and environmental compatibility, differentiating itself from traditional lithium-ion and vanadium-based systems.
Combined strategy
The company describes its technology as particularly well-suited to data centres' operational characteristics. Consistent electricity demand allows these centres to take full advantage of pairing renewable energy, such as wind and solar, with storage solutions that provide reliable supply even when generation is intermittent or when grid volatility causes price fluctuations.
Allegro's systems are designed for incremental investment, which supports deployment at diverse scales. The modular approach allows for adaptation in both hyper-scale centres and smaller, edge data facilities.
Alternative chemistry
A notable aspect of the Allegro storage solution is its use of water-based electrolyte, intended to avoid the constraints associated with critical and scarce raw materials found in conventional battery chemistries. The company states this technology offers a lower-impact alternative and can be deployed safely at larger scales.
The microemulsion electrolyte used in its systems eliminates the reliance on rare metals and is manufactured locally, aiming for lower risks and costs compared to established competitors. Allegro claims that the technology reduces fire risk and supports extended storage durations.
Environmental pressures
Debate continues regarding the environmental consequences of growing digital infrastructure, especially as AI and cloud services proliferate globally.
Dr. Thomas Nann, CEO of Allegro Energy, commented on the intersection of energy needs and environmental issues.
"The exponential growth of generative AI, cloud computing, and digital services has made energy a critical chokepoint in data infrastructure. We believe the future of high-performance computing does not need to come at the cost of the planet. With our technology, data centres can be powered entirely by renewables, supported by reliable, cost-effective long-duration storage."
Allegro Energy's storage technology is presented as enabling data centres to make use of renewable sources while maintaining 24/7 uptime, thereby helping operators address decarbonisation targets and regulations. The company states that the potential to reduce cycling costs and environmental impact addresses two key challenges facing energy-intensive data operations.
Industry positioning
The company highlights the broad applicability of its energy storage solution for different sizes and types of data centres. The local manufacture of core components and avoidance of complex supply chains are cited as additional advantages by Allegro Energy.
The effectiveness and viability of Allegro's technology will continue to be monitored as the sector navigates increasing energy costs, evolving sustainability mandates, and growing consumption patterns linked to global digitalisation.
