Across Europe, high-voltage electrode boilers are emerging as essential tools in the continent’s clean energy transition. These systems convert surplus renewable electricity into steam or hot water, helping reduce emissions from industrial and district heating applications. Finland, which aims for carbon neutrality by 2035, is at the forefront of this shift, actively investing in electrode boiler deployment to meet interim targets under the EU’s Recovery and Resilience Facility (RRF).
Electrode boilers deliver zero emissions at the point of use and provide full modulation from 0–100% output. Their rapid responsiveness enables grid stabilization by absorbing excess electricity during times of high renewable generation, reducing curtailment and balancing supply-demand mismatches. Finland’s growing wind energy capacity—nearly 7,000 MW by the end of 2023—makes this capability critical.
These boilers also allow facilities to capitalize on negative electricity prices by participating in the reserve market, where consumers are paid to absorb surplus power. According to CTI Vice President Juha Mäntynen, a 50 MW boiler can generate up to €150,000 in one hour under favorable conditions.
CT Industrial Oy (CTI) and Acme Engineering have partnered to expand boiler deployment across Finland and Europe. Acme’s CE-marked systems, including jet-type, immersed electrode, and horizontal hot water boilers, support both new and retrofit projects. Recent installations include a 10 MW boiler in Jepua, a 15 MW boiler in Honkajoki, and two 50 MW boilers slated for Kajaani. One innovative design uses a single set of boilers to deliver two different thermal outputs without doubling the boiler capacity.
District heating in Finland, serving half the population through 16,000 km of insulated pipes, is transitioning from biomass to cleaner technologies like electric boilers and heat recovery. CTI is also heavily engaged in the process industry sector, which is expected to be a major area of future growth for electrode boiler applications.
By supporting emissions reduction, energy security, and flexible energy use, electrode boilers play a vital role in helping the EU meet its decarbonization and RRF milestones.
