In August, the Council of State dismissed objections to the WarmtelinQ network, a 25-kilometre underground heat pipeline designed to transport waste heat from Rotterdam harbour to approximately 120,000 homes and businesses. Despite rising costs from an initial €650 million to over €1.1 billion, project sponsors indicated that financing is sufficient following additional funding from the Ministry of Climate and Green Growth.
