The chemical company BASF Construction Chemicals is planning the construction of a large-scale solar park, but is facing unclear questions about power marketing. The project exemplifies the infrastructural challenges facing energy-intensive industrial companies in the course of the energy transition: While generation capacity is plannable, there is a lack of suitable mechanisms for direct marketing and grid integration of larger renewable generation volumes. For the building materials industry, which is among the most energy-intensive sectors, solving such marketing issues could be a watershed for future decarbonization strategies.
