Electrifying Industrial Heat Without Rebuilding the Entire Plant
Industrial heat is one of the most difficult parts of the energy transition.
Factories need reliable heat every hour.
Production schedules cannot depend on unstable energy economics.
Steam, hot air, dryers, kilns and process heat must be available when needed.
Thermal batteries help solve this problem by converting electricity into stored high-temperature heat
and discharging that heat into industrial processes.
Instead of burning fossil fuel continuously, a facility can use electricity strategically,
store thermal energy and release heat when production requires it.
This can reduce fossil fuel exposure, improve cost stability and support decarbonization without
forcing the company to rebuild the entire process.
What This Means in Practice
A thermal battery can support industrial sites by helping them:
- Reduce gas or coal consumption
- Use electricity when prices are attractive
- Store energy as heat
- Deliver steam, hot air or process heat
- Reduce CO2 emissions
- Improve resilience against fuel price volatility
- Create a pathway toward lower-carbon production
- Structure projects with third-party capital where feasible
This is not a universal solution.
It works best where the heat demand is large, stable and technically accessible.
Best Applications
- Steam systems
- Industrial dryers
- Food processing
- Chemicals
- Textiles
- Paper and pulp
- Mining
- Industrial utilities
- Glass and ceramics
- Process air heating
- Kiln support
- Large manufacturing plants
- Continuous production sites
When Thermal Batteries Work Best
The strongest cases usually involve:
- Thermal demand above approximately 2 MWth
- Annual fossil fuel consumption around 20 GWh or more
- Centralized boiler, steam or hot-air system
- Continuous or near-continuous operation
- Activity during nights and weekends
- Short integration distance between heat source and process
- Available electrical capacity or upgrade potential
- Access to land or space for equipment
- Strong pressure to reduce fuel cost or CO2 emissions
- A counterparty strong enough for long-term financing structures
The site does not need to consume full load 24/7.
But it should have a meaningful and repeatable heat profile.
Required Screening Data

Commercial Models
Depending on project size, counterparty strength and technical profile, thermal battery projects
may be structured through:
- Direct CAPEX
- Project SPV
- Heat-as-a-Service
- Storage-as-a-Service
- PPA-linked structure
- Third-party funded project company
- Long-term heat supply agreement
No-CAPEX or reduced-CAPEX structures may be possible, but they depend on the project,
the customer’s credit profile, contract duration, technical risk and economics.
