Publieke samenvatting / Public summary

With an increasing share of electricity generated by renewables such as wind and solar, there is an opportunity for industry to electrify their processes and thereby reduce their dependency on fossil fuels and associated CO2 emissions. Technologies such as direct electric heating and heat pumps are good solutions to achieve this. However, with increasing share of wind and solar, the electricity supply and thereby its prices, have become more volatile. By using heat storage, the industrial heat demand is no longer coupled with simultaneous electricity use. A combination of heat storage technologies and electrification technologies can be expected to result in optimal use of renewable electricity but the optimal configuration depends on the specific industrial processes (e.g. temperature of heat, batch/continuous process), the site characteristics (e.g. size of electrical connection, waste heat availability and safety requirements) and the actual performance of the technologies (e.g. start-up times, part-load performance, standing losses, coefficient of performance, efficiency).

The goal of the project is to develop a calculation tool to determine the optimal configuration of electrification technologies and their impact on reducing CO2 emissions of industrial processes. To achieve this goal, the project has specific targets:
• Identify the main inputs and outputs/KPI of the calculation tool and electrification technology characteristics;
• Verify electrification characteristics under dynamic conditions by testing them in the purpose-build Carnot Lab;
• Apply the calculation tool to several use-cases provided by end-users

Korte omschrijving
Within this project, the consortium will cooperate to accelerate the electrification of industry and the associated reduction in CO2 emissions. Processes from Trespa and Trinseo will be used as use-cases from end-users. The activities of the project consist of defining and collecting the input parameters the characteristics of the electrification and heat storage technologies analyzed in the tool and by defining the desired outputs/KPI’s of the calculation tool.
The characteristics of the technologies are subsequently verified in the Carnot Lab, a purpose-build laboratory at TNO Petten for testing industrial heat systems up to 2 MWth. The application of the calculation tool by the industrial end-users on their use-cases will provide insight in both the added value of the calculation tool as well as the impact of the electrification on achieving CO2 neutral industrial heat systems.

The key results of the project are the methodologies, knowledge and tools, that will be further applied to support industrial end-users and technology providers in their development towards a CO2 neutral industrial heat system. The verification measurements of electrification technologies under dynamic conditions provides insight to the performance characteristics and its contribution to electrification of the industry. By application to use-cases from end-users, the calculation tool is expected to provide guidance and help end-users in deciding their optimal strategy to achieve a reliable heat supply for their processes whilst achieving maximum reduction in CO2 emissions. This will speed-up the electrification of the industry and in particular the flexible use of renewable electricity by the industry. This in turn supports the further growth of the renewables in the electricity production.
