FAQS about Thermal energy storage industrial waste heat recovery

Are TES systems a viable option for waste heat recovery?

Industrial activities have a huge potential for waste heat recovery. TES systems overcome the intermittence and distance of the IWH source. More than 35 IWH case studies of on-site and off-site TES systems are reviewed. On-site TES systems in the basic metals manufacturing are the most recurrent option.

How does thermal energy storage work?

“The integration of thermal energy storage with phase change materials allows recovery and storage of waste heat from combustion gases or other surplus heat sources to preheat the air entering the furnace,” explains Royo. When a phase change material melts or solidifies, a great amount of energy is absorbed or released.

What are the recurrent options for waste heat recovery?

More than 35 IWH case studies of on-site and off-site TES systems are reviewed. On-site TES systems in the basic metals manufacturing are the most recurrent option. Water, erythritol and zeolite are the TES materials more used in IWH recovery. Industrial activities have a huge potential for waste heat recovery.

Can thermal energy storage help achieve a low-carbon future?

Moreover, already in 2014, the IEA highlighted the use of thermal energy storage for waste heat utilization as a key application to achieve a low-carbon future due to the temporal and geographic decoupling of heat supply and demand.

Is waste heat recovery possible in steel manufacturing?

One prominent method in steel manufacturing, which we explore further in this study, is through energy optimization and exploring options for waste heat recovery. Heat recovery potential in the steel industry has been investigated since many years.

Can industrial waste heat be recovered?

Industrial activities have a huge potential for waste heat recovery. In spite of its high potential, industrial waste heat (IWH) is currently underutilised.
