Industrial electrification is reshaping the future of heavy industry

Industrial electrification means replacing fossil-fuel-based energy use with clean electricity in industrial processes. It is emerging as one of the most promising pathways toward low-carbon production because it can reduce emissions directly at their source while also creating opportunities to redesign processes and improve overall efficiency. However, industrial processes differ widely in their temperature needs, materials, operating conditions and integration requirements, so no single technological solution can address all applications.

A broad range of technologies is being developed to meet these different needs. These include resistive and induction heating solutions, plasma technologies capable of achieving extremely high temperatures, and hybrid systems that combine electricity with clean fuels such as hydrogen. In addition, existing industrial units can be partially electrified to improve flexibility and reduce emissions, enabling a gradual transition without replacing all infrastructure at once. 

At VTT, research activities focus on closing the gap between promising electrification concepts and industrial implementation. This includes experimental testing with facilities from lab to pilot-scale such as electrically heated rotary kilns, and techno-economic modelling to assess performance and cost competitiveness. 

Beyond technical feasibility, understanding the economic conditions under which electrification becomes competitive is essential for guiding industrial investment decisions. Close collaboration with industrial partners is essential, because electrification solutions must work not only in principle, but also within real production environments, existing infrastructure and investment constraints.

This need for applied research and piloting is also reflected in the EU’s recent Electrification Action Plan. The Commission highlights that many clean electric technologies are already available, but that several industrial applications, especially higher-temperature processes, still require research, demonstration and scale-up before they can become commercially available. The plan also calls for sector-specific electrification roadmaps, industrial flexibility solutions, modular technology development and stronger cooperation across value chains. This reinforces the importance of R&D environments where new electrification concepts can be tested, modelled and adapted to real industrial processes before full-scale investment decisions are made.

Beyond direct emission reductions, electrification can also create new opportunities for carbon management. Some electrified processes may produce more concentrated carbon dioxide streams that are easier to capture and utilise. In certain cases, particularly when biomass-based processes are involved, combining electrification with carbon capture may even enable negative emissions. 

As industry becomes more electrified, its dependence on electricity increases significantly. This will raise electricity demand and make industrial energy use more dynamic, creating new requirements for generation capacity, grid connections, storage and demand-side flexibility. At the same time, reducing reliance on fossil fuels can strengthen energy independence and improve resilience against volatile fuel markets.

This shift also creates new challenges. Electricity-based industrial systems depend on reliable infrastructure, stable grid operation and secure digital control systems. Ensuring a robust, flexible and cyber-secure electricity system is essential if industrial electrification is to scale beyond individual pilots and become part of normal industrial operation.

Industrial electrification represents a fundamental shift in how energy is used in industrial production systems. It links industrial transformation with clean electricity, climate policy, energy security and competitiveness. Its success will depend not only on individual technologies, but also on how quickly research, piloting, infrastructure development and industrial investment can move together. For this reason, electrification is expected to play a central role in shaping the future of industry in Finland and beyond.
