Why Decarbonizing Process Heat is a Strategic Priority for Saarland
The electrification of industrial heat is a decisive lever for a successful and prosperous economic future in Saarland. For local industries, this presents a clear strategic imperative as the state undergoes its historic Strukturwandel (structural change).
Driving the Industrial Transformation As Saarland transitions from its industrial past to a future centered on technology and green industry (like battery production and green steel), there is a massive demand for clean energy solutions. Thermal batteries are a core technology for a green industrial future, essential for attracting new industries and future-proofing existing ones.
Decarbonizing Steel and Automotive Production Saarland's world-class steel and automotive industries are the backbone of its economy. These sectors have a huge and constant demand for high-temperature process heat. Electrifying this heat with thermal batteries is the key to producing 'green steel' and sustainable automotive components, ensuring these industries remain global leaders.
Providing Energy Security and Cost Stability The state's industrial base is highly exposed to volatile natural gas prices. Thermal batteries offer a stable, electrified alternative, providing long-term cost predictability for essential process heat and insulating businesses from geopolitical energy risks.
Capitalizing on Excellent Solar Resources Located in one of Germany's sunniest regions, Saarland has excellent potential for low-cost solar power. Our thermal batteries are designed to absorb this abundant, clean electricity and convert it into high-value, dispatchable heat for 24/7 industrial operations.
VIRDI provides the technology and expertise to implement the industrial heat transition in Saarland reliably and economically.
At the core of our solution is the innovative bGen™ technology from our partner Brenmiller Energy. It enables a highly efficient and cost-effective electrification of your heat-dependent processes, turning renewable electricity into industrial-grade steam.
Our thermal batteries use electric heaters—powered by low-cost electricity from the grid—to heat a storage medium of crushed rock to very high temperatures. This stored heat is then used on demand to generate high-temperature steam (up to 550°C) for your industrial processes, reliably and with zero on-site emissions. It's a simple, robust, and highly effective way to replace your gas boilers.
Thanks to a modular design that is scalable from 10 MWh to over 1 GWh, the system can be flexibly tailored to your specific heat demand at your facility in Saarland. The integration into your existing steam infrastructure is fast and designed to minimize operational downtime, ensuring a smooth transition.
We offer two options for your project in Saarland to best suit your financial strategy: the direct purchase of the system (CAPEX), or our "Heat-as-a-Service" (HaaS) model, an energy service contract where you only pay for the heat you consume (OPEX), avoiding the upfront investment entirely.
Your Advantages with VIRDI Thermal Batteries
Choosing to electrify your heat with VIRDI's thermal batteries provides a range of powerful, long-term advantages for your business.
Unmatched Durability and Long Lifespan The bGen™ technology uses natural, non-degrading materials like crushed rock. This allows for an operational lifetime of over 30 years without the cycle degradation known from chemical batteries, ensuring a reliable and long-lasting asset for your facility.
Maximum Cost-Effectiveness With a competitive cost per unit of stored energy (kWh) and the ability to charge using low-cost electricity from the grid, our systems are an economically attractive and often cheaper alternative to conventional gas boilers over the project's lifetime.
Low Supply Chain and Material Risk We use low-cost, globally abundant materials like steel and rock, avoiding the supply chain volatility and ethical concerns associated with materials like cobalt or lithium. Our partnership with Brenmiller Energy's gigafactory ensures unrivaled production capacity and supply chain security.
Zero On-Site Emissions Our technology allows you to replace fossil fuels one-for-one and completely eliminate the CO₂ emissions from your on-site heat generation. This will decisively accelerate the achievement of your company's decarbonization goals and strengthen your position as a sustainable leader in Saarland.
We have streamlined our development process into four clear and simple phases, ensuring transparency and partnership at every step.

Frequently Asked Questions
A thermal battery is a system that converts electrical energy into storable high-temperature heat. It uses electricity to heat a solid-state storage medium (like crushed rock). This heat can then be dispatched on demand, typically as steam, for use in industrial processes.
It is ideal for any energy-intensive industry requiring process heat or steam. In Saarland, this is particularly relevant for the steel industry, automotive manufacturing and suppliers, food and beverage production, and other heavy manufacturing sectors.
In this model, VIRDI (or a partner) invests in and operates the thermal battery on your site. As the customer, you make no upfront investment (CAPEX) and simply pay a contractually agreed price for the amount of heat you actually use (OPEX)—similar to a natural gas supply contract.
The main difference is purpose and durability. Lithium-ion batteries store electricity to discharge it as electricity. Our thermal battery converts electricity to heat, which is far more efficient for thermal processes. Furthermore, it uses robust, non-degrading materials for a 30+ year lifespan, whereas lithium-ion batteries degrade with each charge cycle.
The footprint is relatively small thanks to the compact, modular design. The exact space requirement depends on the needed storage capacity. The system can be flexibly adapted to the conditions at your plant site in Saarland, including integration into existing industrial facilities
