Que: Why did you choose thermal battery energy storage over lithium-ion?

Ans: Lithium-ion is a proven technology, but it comes with limitations - especially for large-scale, long-duration, energy storage. At Voltanova, we chose thermal energy storage because they offer a far more resilient, scalable, and cost-effective path forward.

Our system can be built entirely with materials 100 percent sourced and manufactured in India, eliminating dependence on imported critical minerals. It’s designed for industrial energy and grid applications, where long duration, reliability, and cost are critical.

The advantages are clear:
• Up to 1/5th the cost of lithium-ion storage
• Fully domestic sourcing, aligned with Make in India and Atmanirbhar Bharat
• Simpler manufacturing using existing industrial capabilities
• Scalable and modular design for diverse applications
• No exposure to global battery supply chain risks
• Longer lifespan with minimal degradation, making it ideal for long-duration storage.

In short, thermal storage allows India to build a homegrown, globally competitive energy solution - and that’s why we’re building it.

Que: How does Voltanova compete on technology, scalability, and cost?

Ans: At Voltanova, we’ve designed our thermal battery system to outperform both traditional and emerging energy storage technologies on three key fronts - cost, performance, and scalability. On cost, we are up to 60 percent more affordable than other thermal energy storage alternatives, while still delivering a system engineered for decades of reliable use. In terms of performance, our batteries operate at temperatures of up to 2000°C with 95 percent efficiency for direct heat, directly addressing the most critical needs of heavy industries. When it comes to scalability and deployment speed, our modular, retrofittable design allows installations to be completed in just a matter of weeks. Combined with our AI-powered energy management platform, customers can intelligently dispatch energy for both heat and power use cases.

Most importantly, Voltanova is purpose-built for long-duration storage, serving industries and grid-scale applications where the impact truly matters. This is what positions us not just as another battery storage company, but as a category leader in industrial decarbonisation.

Que: Do you think industrial heating has been a blind spot in clean energy transition strategies?

Ans: Yes. Industrial heating has been one of the most overlooked areas in the clean energy transition. While the world has made strong progress in sectors like transportation and electricity, industrial heat - which is responsible for nearly 30 percent of global emissions - has remained largely unaddressed. The reason is simple: industries require high temperature energy, and conventional renewable solutions have not been able to meet those needs reliably or cost-effectively. At Voltanova, we see this as one of the single biggest opportunities to fight climate change. By building next-generation thermal energy storage systems that deliver affordable, reliable, and sustainable high-temperature heat, we’re not just closing a critical gap - we’re unlocking energy independence and industrial competitiveness.

Que: Can you share details about your upcoming market launch, key clients, deployment scale, and early performance results?

Ans: We are on track to deploy industrial-scale thermal energy storage systems next quarter. These will be live in real industrial environments, delivering reliable high-temperature energy for heavy industry. What’s exciting is that we’ve already secured order interest worth over USD 6 million from leading industrial customers, and we’re now seeing a surge of inbound interest from international markets as well. For us, these deployments will set the foundation for scale. Once in operation, they will validate how long-duration thermal storage can decarbonise both heat and power at a cost that simply hasn’t been possible before. We see this as the beginning of the world’s lowest-cost pathway to clean industrial energy.

Que: What partnerships have you built with industrial players for pilots or scale ups?

Ans: We’ve built strategic partnerships with leading industrial players to deploy and scale our technology. In India, we already have order interests worth USD 6M from leading industry players, and we are also in conversations with large corporations and PSUs. Additionally, we are actively collaborating with institutions such as IISc Bangalore, T-Hub, and leading industry bodies. These partnerships enable us to combine deep industrial expertise with real customer demand, ensuring that our thermal energy storage systems are ready for deployment at scale while addressing the critical need for low-cost, sustainable, high-temperature energy.

Que: Do you see India having the manufacturing capacity to become a global exporter of thermal battery systems in the next decade?

Ans: Absolutely. India is uniquely positioned to emerge as a global hub. We already have world-class engineering talent, a strong industrial base, and rapidly expanding renewable energy capacity. With initiatives like PLI, VGF etc. the ecosystem is aligning to enable clean energy manufacturing at scale.

What truly sets India apart is the ability to deliver cost-competitive, high-quality industrial products - something global markets value deeply. Combined with deep R&D and strong industrial partnerships, this creates a foundation not just for meeting domestic demand, but for positioning India as a leading exporter in the global energy transition.

At Voltanova, we see India as both our launchpad and our long-term manufacturing and innovation hub. Our goal is to build here, scale globally, and play a defining role in decarbonising heat and power worldwide.
