In the presence of Minister Jetten for Economic Affairs and Climate, the province of South Holland, the Ministry of Economy and Gasunie on Monday 11 July signed the Covenant Heat Transport Network South Holland in the Leiden region. They thus give the green light for the construction of the underground heating pipeline from Rijswijk to Leiden. This is an extension of WarmtelinQ, the heat transport network that will connect the port of Rotterdam with The Hague. It is expected that the construction of the pipeline can start during 2025, and that the first heat can be delivered to Leiden and surrounding municipalities by mid-2027.
In addition to the agreement, an agreement between Gasunie and Vattenfall also makes it possible to lay the pipeline. Vattenfall will take the first heat from the heat transport network and supply it to its customers in the existing heating network in Leiden and the surrounding area. Eventually, approximately 50,000 homes and other buildings will be able to run from natural gas and receive heat in a sustainable way.
For Jeannette Baljieu, Provincial Director of South Holland, important steps have now been taken to develop the heat transport network in South Holland. “With Vattenfal, a recognized party from the heating industry has committed to WarmtelinQ. This also guarantees the realization of the WarmtelinQ route Rijswijk-Leiden. In addition, it is now possible for Gasunie to apply for the investment grant from the province of South Holland ”.
The overall WarmtelinQ project involves an investment of several hundred million euros. With the agreement signed today, the province of South Holland provides an investment grant of € 81 million for the expansion to the Leiden region. The ministry is making an additional € 22.5 million available for this expansion. The Board of Directors of Gasunie (100% project owner of WarmtelinQ) has been able to make a positive investment decision with these grants and with the contract with Vattenfall, so that the construction of this route can start. Ulco Vermeulen, Member of the Board of Gasunie: “WarmtelinQ is an important pillar in our transformation from a gas infrastructure company to an energy infrastructure company. More importantly, the use of residual heat means a significant reduction in natural gas and CO2 reduction and helps people and companies to heat buildings in a future-proof and affordable way. ”
Existing and new heating network
WarmtelinQ is an underground heat transport pipeline to which several customers, such as energy suppliers, and (sustainable) heat sources can be connected. The route from the port of Rotterdam to The Hague will first be built.
The construction of the Rijswijk-Leiden route is the next step in the realization of a heat transport system in South Holland. The heat transport network has sufficient capacity to supply more homes, businesses and greenhouse horticulture along the route with heat in the long run.
Regional energy strategy
The Leiden region confirms the importance of WarmtelinQ for the Leiden region. Liesbeth Spies, President of the Regional Energy Strategy Holland Rijnland: “With the arrival of WarmtelinQ in our region, the use of sustainable heat is getting closer to too many households. We have worked hard together and are proud of the agreement reached today. A good step forward in the energy transition for Holland Rijnland ‘.
Heat from the port of Rotterdam
The heat comes from companies in the port of Rotterdam. This heat is released during (industrial) processes and often ends up unused in the air or water. By using this heat to heat buildings and greenhouse horticulture, less heat with natural gas must be produced. In addition to using heat from the port, it is very important that other sustainable heat sources are used, such as geothermal energy.
