Voltanova | Industrial Thermal Energy Storage Solutions

Energy Storage

Sustainable Development Goals

SDG 13 – Climate Action, SDG 7 – Affordable and Clean Energy, SDG 9 – Industry Innovation and Infrastructure

Company Overview

Voltanova Energy Private Limited is a Bengaluru-based deep-tech company that develops thermal energy storage systems for industrial users. The company stores renewable electricity as high-temperature heat and releases it as process heat or, through a heat-to-power conversion cell, as electricity. Its stated aim is to give heavy industry round-the-clock clean energy without dependence on fossil fuels.

The company operates from the Entrepreneurship Center at the Indian Institute of Science (IISc) and is incubated through the Foundation for Science, Innovation and Development (FSID), a Section 8 company established by IISc. It was co-founded by Jaicky Kumar, who serves as CEO, and Deepak Mishra, who serves as COO. The wider team includes scientists and thermal design engineers working on materials, heat transfer and system design.

Voltanova’s work spans heat storage, heat-to-power conversion and energy management software. It positions these for hard-to-abate sectors such as steel, cement, textiles and food processing, where high-temperature heat makes up a large part of energy use.

In March 2025, textile manufacturer RMP Group announced a partnership to adopt Voltanova’s system for its operations in Panipat and Faridabad. In the same month, the company announced more than ₹50 crore in order interest. In 2025, its leadership also spoke publicly about the technology in a Forbes India podcast and a pv magazine interview.

Why These SDGs Matter

SDG 7 applies because the systems store renewable electricity as heat and release it when industrial plants need it. This allows solar and wind power to be used outside generation hours and widens the practical use of clean energy in factories.

SDG 9 applies because the company develops new storage and heat-to-power hardware in an academic research setting. The technology is aimed at upgrading energy-intensive industrial processes that currently rely on fossil-fuel heat.

SDG 13 applies because the stated purpose of the system is to replace fossil fuel use in industrial heat and power. Industry is a major source of greenhouse gas emissions, and process heat in sectors such as steel, cement and textiles is among the harder areas to decarbonize. Direct displacement of fossil fuel heat at the point of use ties the offering to emissions reduction.

Approach & Methodology

Voltanova's system is built around three technical layers: heat storage, heat-to-power conversion and software control.

The storage layer holds heat in widely available materials rather than rare-earth components. It is engineered for thermal retention, and a discharge unit delivers steady output when the plant needs it. The company describes the system as capable of charging and discharging at the same time, which lets it absorb surplus renewable electricity and supply heat during non-peak hours. In a pv magazine interview, the CEO described the engineering challenge as spanning materials science, product design, thermal efficiency and system integration, with the design intended to limit heat loss over long storage periods.

The heat-to-power layer is a thermophotonic cell. It converts high-temperature heat into electricity with no moving parts, using III-V semiconductor materials with a tunable bandgap. It can run on its own or in a hybrid arrangement with the storage unit.

The software layer is an AI-based energy management platform. It analyses real-time consumption patterns to predict demand and optimise energy use, and it can network several storage units for load balancing and shared data insights.

Delivery follows a modular design so that units can be matched to plants of different sizes and connected to existing industrial processes. The CEO has also stated that the design can use locally sourced materials, which supports domestic supply chains.

Market Position

Voltanova operates in the long-duration energy storage segment, with a focus on high-temperature thermal storage for industrial heat. Its primary customers are energy-intensive manufacturers, and reported partners include a textile producer and a food processing company.

The company states that its system costs about one-fifth of conventional energy storage and operates at 95% efficiency. These figures are company-reported. It presents the offering as an alternative to lithium-ion storage that relies on abundant materials rather than scarce imported minerals.

Technology differentiation rests on combining thermal storage with a heat-to-power cell and an energy management layer in one platform. The company is at an early commercial stage, with announced order interest and a first named industrial partnership.

Procurement Considerations
  • Match storage temperature range, duration and charge and discharge rates to your process requirements
  • Ask for third-party verification of the stated efficiency and cost comparison figures
  • Request commissioning references and operating data from installed sites
  • Assess integration with existing boilers, furnaces and electrical infrastructure, and secure renewable power for charging
  • Confirm commercial availability, warranty and performance guarantee terms, especially for the thermophotonic cell option
  • Obtain lifecycle cost estimates, maintenance schedules and service coverage for your location
  • Review thermal safety compliance, applicable Indian standards and quality certifications such as ISO 9001 and ISO 14001
  • Evaluate vendor financial standing and contract structure for a startup-stage supplier

Funding, Recognition & Ecosystem
  • Incubated at the Foundation for Science, Innovation and Development (FSID), established by the Indian Institute of Science
  • Grant from Zerodha, channelled through FSID at IISc
  • Based at the Entrepreneurship Center, Indian Institute of Science, Bengaluru
  • Described on its website as backed by IISc
Natnavi Analysis

Industrial heat is one of the harder parts of the energy transition. Much of it is high-temperature and has traditionally relied on fossil fuels, and electrochemical batteries are not a natural fit for it. Voltanova addresses this by storing renewable electricity as heat close to where it is used, which is why the company is relevant to India's industrial decarbonization.

Its strengths include a research-institution origin, a technology stack that spans storage, power conversion and controls, and a design that can draw on abundant materials. The named partnership with RMP Group and the reported order interest suggest early commercial traction in textiles and food processing.

Buyers should note that the company is at an early stage. The cost, efficiency and savings figures in public coverage come from company statements, and they are worth examining against site-specific data during due diligence. The thermophotonic cell is a newer technology, so procurement teams may want to check its readiness for their use case. Operating data from the first installations will be an important indicator of how the system performs over time.

Overall, Voltanova is a notable early entrant in Indian industrial thermal storage, and its results in the next few deployments will shape how significant it becomes.
