Maximum supply temperature as a function of heat capacity
The graphic shows the maximum supply temperature of high-temperature heat pump technologies from different manufacturers as a function of the heat capacity. More information on the individual technologies is published on the IEA HPT Annex 58 website (https://heatpumpingtechnologies.org/annex58/task1/).

General comparison between steam generation with natural gas-fired boilers and heat pump technologies
The graphic shows conventional steam generation with natural gas-fired boilers compared to steam generation with heat pump technologies. In steam generation with natural gas-fired boilers, the steam is generated at least at the highest pressure level needed in the production process and then expanded to lower pressure levels. In comparison, when generating steam with a heat pump, it is advantageous if only the amount of steam required at the corresponding pressure level is also generated at this pressure level. Expansion to a lower temperature level should be avoided when using heat pumps. More information on steam generation with heat pumps can be found in the IEA HPT Annex 58 Task 2 report (https://heatpumpingtechnologies.org/annex58/task-2-integration-concepts/).
