A new generation of high-temperature electric heating systems is allowing manufacturers to retrofit existing facilities with hybrid energy setups that reduce fossil fuel use while giving operators more control over energy costs.
How Hybrid Electric Heat Works In Practice
Heavy industry has long relied on fossil fuels to generate the extreme heat needed for processes such as cement production, glassmaking, and chemical manufacturing. In many cases, these processes require temperatures well above 1,000°C, which has historically limited the viability of electric alternatives.
However, new systems developed by companies such as NOC Energy and Electrified Thermal Solutions are changing that equation by combining electric heat generation with existing combustion infrastructure rather than replacing it entirely. As NOC Energy puts it, its approach is about “reducing industrial energy costs while cutting emissions.”
NOC Energy, for example, uses induction-based technology to generate heat by applying electromagnetic fields to steel components inside insulated modules. These systems can deliver temperatures of up to 1,200°C, with higher targets in development, and can be connected directly to existing kilns or industrial processes. Heat is transferred via air or gas flows, allowing facilities to integrate the technology without major redesign.
Electrified Thermal Solutions takes a different approach, using electrically conductive firebricks that both generate and store heat when current passes through them. These bricks can reach temperatures of up to 1,800°C, placing them within the range required for some of the most energy-intensive industrial applications. The company describes its goal as “pioneering the future of zero-carbon industrial heat cheaper than natural gas.”
Both approaches share the common principle that, rather than forcing a full transition away from fossil fuels, they allow operators to introduce electric heat gradually alongside existing systems.
Why Hybrid Models Are Gaining Traction
The hybrid model reflects a practical reality for many industrial operators, where full electrification can involve significant cost, risk, and disruption. By contrast, a system that can operate on both electricity and fossil fuels allows companies to adapt over time while maintaining operational continuity.
As NOC Energy’s chief executive has explained, many companies want the flexibility to choose the lowest-cost energy source at any given time, rather than committing entirely to one approach. That flexibility is becoming increasingly valuable as energy markets become more volatile and influenced by factors such as renewable generation and geopolitical pressures.
This is where thermal storage plays a critical role. Both induction-based systems and thermal batteries can store heat for hours, allowing facilities to use electricity when it is cheapest, for example during periods of high wind or solar output, and then draw on that stored heat when prices rise. As NOC Energy explains, “storage creates flexibility by disconnecting the timing of consuming power and discharging heat.”
The result is not just a lower-carbon process, but a more economically optimised one, where energy consumption can be aligned with pricing conditions rather than fixed demand patterns.
The Cost And Carbon Equation
Industrial heat is one of the most challenging areas to decarbonise, accounting for a significant share of global emissions. Estimates suggest that around 70 per cent of industrial heat is still generated using fossil fuels, contributing roughly a quarter of global CO₂ emissions.
Electric heating technologies have existed for some time, but scaling them to high temperatures has presented durability and cost challenges. Traditional resistance heaters, for example, tend to degrade quickly at extreme temperatures, increasing maintenance costs and limiting their practical use.
The newer approaches aim to overcome these limitations by separating the heating mechanism from the hottest parts of the system or by using materials already proven to withstand high temperatures over long periods. Induction systems, in particular, avoid direct exposure of key components to heat, which can extend their lifespan and improve reliability.
Also, the ability to store heat and use low-cost electricity improves the overall economics. In fact, in regions with strong renewable generation, some providers suggest that electric heat systems can already compete with natural gas on cost, particularly when incentives or carbon pricing are taken into account. Electrified Thermal Solutions, for example, highlights that its systems can deliver “unprecedented near-flame temperatures… offering industrial heat cheaper than fossil fuels.”
What Does This Mean For Your Organisation?
For businesses operating in energy-intensive sectors, these developments introduce a new way to think about both risk and opportunity.
Retrofitting existing facilities with hybrid systems reduces the need for large-scale capital replacement, making it easier to begin reducing emissions without committing to a full infrastructure overhaul. This is particularly relevant for industries with long asset lifecycles, where equipment may be expected to operate for decades.
The ability to switch between energy sources also provides a hedge against price volatility. As electricity markets become more dynamic, driven by renewable supply and demand fluctuations, organisations that can shift their energy consumption patterns are likely to be better positioned to manage costs.
Greater visibility into energy use and system performance also becomes more important, as hybrid systems introduce additional layers of operational decision-making, including when to use stored heat, when to draw from the grid, and how to balance efficiency with output requirements
It should be noted, however, that while hybrid electric heat offers some valauable advantages, it is not a complete solution on its own. The long-term direction for many sectors is likely to involve deeper electrification, supported by cleaner grids and advances in storage and infrastructure.
What these systems essentially provide is really a practical bridge between today’s fossil-dependent processes and a lower-carbon future. By allowing companies to reduce emissions while maintaining flexibility and control, they make it more feasible to begin that transition without waiting for perfect conditions.
For many organisations, that balance between immediate practicality and long-term change is likely to define how quickly they can adapt to the evolving energy landscape.
