Abstract(s) :

(Anglais) For decades, the use of geothermal energy in Belgium focussed mainly on shallow applications. In comparison with other Western European neighboring countries, shallow geothermal development started later and grew slower despite the introduction of multiple stimulation measures by local and federal government. However, the mandatory legislation on building energy performance and the obligation to use renewable energy sources stimulates sales numbers in the heat pump market. This gained momentum since the tightening of the obligated energy level in 2018. In that regard, air source heat pumps are still the most favorite type but ground source heat pumps are gaining market share. Concerning deep geothermal energy, for almost 30 years there was only one thermal project in operation in the vicinity of Mons. Since 2010, new initiatives in Flanders and Wallonia were set up. In 2018, a first new deep geothermal project was brought into operation in Mol. It operates as a combined power and thermal energy installation with in first phase about 15 MW heat and 1,5 MW power. On long term this will be expanded to 5 MW power production. Almost simultaneously, the Walloon government launched an initiative with the aim for developing three pilot projects in the area of Charleroi and Mons. This paper gives an overview of the status of shallow and deep geothermal energy applications in Belgium with figures on installed capacity and overall environmental benefits.
