A large part of the existing built environment is currently heated with natural gas. Shell believes in geothermal heat as a sustainable alternative. Heat that is extracted at depths of 500-4000 metres is what we call geothermal heat. The deeper the source, the warmer the water. Hot water is pumped up and used to heat buildings and homes but is also used for greenhouse horticulture and industry. Because of our subsurface expertise and the experience in working on large and complex projects, Shell is well positioned to work on sustainable solutions in the area of heat supply.

In various partnerships, researchers at STCA look at how collective heat systems in combination with renewable power sources can be made reliable and affordable. System and process innovations are necessary for a more efficient design, construction and management of a heat grid and a good interaction between parties. The researchers map out how much, where and at what cost heat can be extracted through geothermal energy. Part of the research looks at how geothermal heat and residual heat can be stored underground responsibly.

STCA already applies a variation of geothermal technology on a smaller scale. At STCA, the temperature is regulated via underground heat and cold storage along with heat pumps that use renewable power from Dutch wind farms. The four sources, two heat and two cold, are located at a depth of approximately 180 metres. In the winter, the heat sources provide warm water to heat the building. As soon as the water has cooled down, it is stored in the cold sources. The building can be cooled in the summer with this cold water. Once the water has warmed up again, it goes back to the warm sources for storage.

Aardwarmte

Wat veel mensen niet weten is dat ongeveer de helft van alle energie in Nederland opgaat aan warmte. Geen wonder dat voor warmte een hoofdrol is weggelegd in de Nederlandse energietransitie. Hoe we het op een duurzame manier warm krijgen en houden? Aardwarmte is volgens Shell een van de oplossingen. 

Samenwerken in de warmtetransitie

Veel mensen in Nederland zullen zich afvragen wat ze moeten doen als hun cv-ketel aan vervanging toe is. Een nieuwe cv-ketel kopen of een warmtepomp laten installeren? Of wachten totdat de gemeente komt met plannen voor een warmtenet? Op het ogenblik zijn er nog niet zo veel warmtenetten, maar de bedoeling is dat er veel meer gaan komen. Daarvoor is nauwe samenwerking tussen overheden, bedrijven en andere partijen nodig.
