The Netherlands has begun transforming synthetic turf sports pitches into renewable energy powerhouses, whereby a single football field equipped with heat-collection technology can supply green energy to up to 300 homes for an entire year.
The fields function by capturing the heat from the surface of synthetic turf, and then distributing it via underground pipes below the pitch. The heat extracted typically reaches temperatures between 15°C and 30°C , which can then be upgraded using a heat pump to warm nearby buildings, including schools, homes, and swimming pools.
Alternatively, it can be stored in underground thermal energy storage systems for use during colder months
A full-sized pitch can heat between 150 and 300 households, equivalent to saving 150,000 to 300,000 m³ of gas annually. The heat can be used for sports facilities, homes, schools, swimming pools and daycare centres, or shared through district heating networks to benefit entire neighbourhoods.
The initiative is being driven by the Sustainable Sports Facilities team within the Knowledge Centre for Sport & Physical Activity (Kenniscentrum Sport & Bewegen), as part of the Dutch sports sector’s commitment to achieving a 95% reduction in carbon emissions by 2050, in line with the Dutch Climate Agreement.
Leander Lignac, Specialist Sustainable Sports Facilities at the Knowledge Centre for Sport & Physical Activity, said: ‘As an independent and neutral organisation, one of our goals is making owners of sports facilities aware of the possibilities within sustainability. Turning synthetic turf sports pitches into a source of green energy is all about impact – using a single space in multiple ways to solve many challenges at once.
‘Space in the Netherlands is sparse, especially in the cities – so when it’s possible to use conveniently located pitches not just for sports, but for sustainability goals too, these facilities become more future proof. While this technology is not yet widespread, it has the potential to deliver a significant reduction in carbon emissions when scaled up.
‘Ultimately, the sports sector needs to be future proof, and as part of that journey, it is our job to make municipalities and local sports clubs aware of these solutions to help them be realised across the Netherlands.’
Heat collector fields are already operational in Eindhoven, Zaanstad, Gouda, and The Hague. In the Moerwijk district of The Hague, a recent project is supplying three primary schools and a childcare centre with renewable heat, reducing their natural gas consumption by 75 to 85 per cent and cutting annual CO₂ emissions by approximately 30,000 kilograms.
With at least 1,250 synthetic turf football pitches across the Netherlands, the technology has the potential to cut national CO₂ emissions by up to 0.45 megatons per year. Municipalities including Amsterdam and Haarlem are already targeting the renewal of more than 250 pitches as part of a “Scale Up” initiative, with the heat collector technology to be used wherever feasible.
The energy yield is substantial: a full-sized pitch can heat between 150 and 300 households, equivalent to saving 150,000 to 300,000 m³ of gas annually. The heat can be used for sports facilities, homes, schools, swimming pools, and daycare centres, or shared through district heating networks to benefit entire neighbourhoods.
The UK, by comparison, has four times as many, with over 5,000 artificial turf pitches dedicated to sports such as football and hockey.
Stefan Diderich, Director General/CEO of the EMEA Synthetic Turf Council, said: ‘This technology is a prime example of the wider benefits that are being delivered through synthetic turf every day. These fields not only provide a high-quality playing surface, but a source of clean, renewable energy that communities can be built around.’
