Managing heat supply and demand for industry was the theme of the Focus Group Heat Transition on 4 June. Contributions came from Mark Franken, Project/Program Manager at the Port of Rotterdam, Annita Westenbroek, Program Director Heat at ISPT, and Eloi van der Meer, Sales Manager at Siemens Energy. The session was attended by some 25 experts working in or with industrial heat.

Mark Franken kicked off explaining the developments for sustainable heat in the Rotterdam harbour. He showed the anticipated large make-over from a port based on the import, refining and export of conventional energy carriers and chemicals to a port based on hydrogen, CO2, bio-based chemicals, electricity, steam, and heat. The transformation takes place in line with the policy of reducing, re-using and recycling the use of energy. This has major implication for infrastructure in the port, and its environment.
Steam and heat transport form a significant and integrated part of this transformation, and its importance becomes more and more visible for both the infrastructure and activities in the harbour as well as its surroundings which it can provide well through recycling with sustainable residual heat. In the long-term the planned electrolysers will generate considerable sustainable heat that can be used in the nearby greenhouses and built environment in the region of Rotterdam, The Hague and Leiden. Smart use of heat flows and storage can alleviate and interplay efficiently with the upcoming further electrification of much of the energy system in the port.

Annita Westenbroek started off by changing the programme title from ‘Overview heat supply and demand and option for sustainable heat’ into ‘Smart efficient and flexible integration of sustainable heat in the process industry’. She did include an insightful overview and also showed technical solutions, fuels and suppliers for sustainable heat in all temperature ranges and pressures. However, the message she conveyed was that these solutions always form part of a broader and integrated energy system. Often the costs of system integration are up to a factor four higher than just a singular technical solution. To ensure the right transitional integrated configurations, the whole of the energy and heat systems, fuels, electricity, storage, heat pumps and compressors must be assessed. This allows for design in the real setting of the industrial processes together with the industrial needs for the quality of the output. Only then capital expenditures and operational expenditures, energy prices, subsidies, and demand and specifications for energy such as heat can be optimised. This requires a joint approach from the suppliers and industry. Annita illustrated the importance of this with the case of the European cooperation between the paper industry and heat pump suppliers. A salient recommendation was that to establish appropriate SDE++ subsidies for sustainable energy or heat solutions, the government should join in to understand and apply a more integrated approach as well.

Eloi van der Meer underscored the message of Annita in his presentation about the use of and developments in the field of heat pumps. He illustrated the integrated approach Siemens has to sustainable energy and heat systems in the industry. More and more configurations of heat pumps become available integrated with residual heat flows, geothermal energy, compressors, storage, and other flexibility solutions they develop together with their customers.
