Create new value from your energy assets by coupling your wind or solar farm in Hessen with a thermal battery (Power-to-Heat), supplying local industry with reliable, competitively priced process heat.
Expand your portfolio with cutting-edge energy technology by integrating our bGen™ system. Deliver innovative 'Heat-as-a-Service' (HaaS) contracts to industrial clients in Hessen, offering them reliable, sustainable, and cost-efficient heat solutions while strengthening your competitive edge and driving the energy transition forward.
Why Decarbonizing Process Heat is a Strategic Priority in Hessen
The electrification of industrial heat is the decisive lever for a successful energy transition within Hessen's powerful economy. For local industries, this presents a clear strategic imperative.
Achieving Ambitious Climate Targets:
To comply with Hessen's stringent climate protection laws and avoid rising carbon taxes, decarbonizing industrial process heat, a major source of emissions, is no longer optional, it’s a strategic necessity.
Insulating from Volatile Gas Prices:
The state's export-oriented manufacturing base is highly exposed to natural gas price volatility. Thermal batteries offer a stable, electrified alternative, providing long-term cost predictability for essential process heat.
Capitalizing on Wind & Solar Surplus:
With its strong wind resources in the Mittelgebirge and growing solar capacity, Hessen frequently experiences periods of very low-cost electricity. Our thermal batteries are uniquely suited to capture this surplus power, from both wind and sun, and convert it into valuable, dispatchable heat for 24/7 operations.
Gaining a Sustainable Competitive Edge:
By reducing their carbon footprint, companies in Hessen meet the growing sustainability demands of global supply chains, securing a critical competitive advantage in the international market.
VIRDI provides the technology and expertise to implement the industrial heat transition in Hessen 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.
Our thermal batteries use electric heaters to heat a storage medium of crushed rock. 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.
Thanks to a modular design (scalable from 10 MWh to over 1 GWh), the system can be flexibly tailored to your specific heat demand at your facility in Hessen. Integration into your existing infrastructure is fast and minimizes operational downtime.
We offer two options for your project in Hessen: the direct purchase of the system, or "Heat-as-a-Service," an energy service model where you only pay for the heat you consume, avoiding the upfront investment.
Your Advantages with VIRDI Thermal Batteries
Unmatched Durability and Long Lifespan:
The bGen™ technology uses natural, non-degrading materials (crushed rock). This allows for an operational lifetime of over 30 years without the cycle degradation known from lithium-ion batteries.
Maximum Cost-Effectiveness:
With a competitive cost per unit of stored energy (kWh) and the ability to charge using low-cost electricity from Hessen's grid, our systems are an economically attractive alternative to conventional gas boilers.
Low Supply Chain and Material Risk:
We use low-cost, globally abundant materials. Our partnership with Brenmiller Energy's gigafactory ensures unrivaled production capacity and supply chain security.
Zero On-Site Emissions:
Replace fossil fuels one-for-one and eliminate your process heat emissions. This will decisively accelerate the achievement of your company's decarbonization goals in Hessen.

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 Hessen, this is particularly relevant for the chemical, pharmaceutical, automotive, food & beverage, and manufacturing industries.
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 Hessen.
