Executive summary

Industrial manufacturers are under increasing pressure to reduce carbon emissions while maintaining productivity, reliability, and product quality. For many facilities, the greatest challenge is not identifying low-carbon technologies but finding a practical way to implement them.

For over a century, steam has been the preferred method of delivering industrial heat. Steam remains essential for many applications and will continue to play a critical role wherever it provides the best engineering solution.

However, replacing a 10 MW or 20 MW gas-fired boiler with an electric equivalent is often limited by electrical infrastructure, available grid capacity, capital investment, and operational risk. This does not mean organizations need to wait.

By optimizing existing thermal systems and gradually decentralizing suitable low- and medium-temperature process loads using electric process heating technologies, manufacturers can begin reducing fuel consumption, lowering emissions, and improving process performance using the electrical capacity already available today. As steam demand decreases over time, future investments in electric boilers, heat pumps, or other low-carbon technologies become significantly more feasible.

The goal is not to replace steam. The goal is to use the most appropriate thermal technology for each application.
