This week’s Rolex Series event at The Renaissance Club in East Lothian will become one of the most sustainable golf tournaments ever staged, combining green hydrogen, solar energy and expanded grid power to significantly reduce its operational carbon footprint.

The initiative represents the latest evolution of the European Tour Group’s Golf for Good programme and offers an example of how major sporting events can move beyond sustainability commitments towards measurable action and impact.

Hydrogen Takes Centre Stage

The most striking development is the scale of the tournament’s hydrogen deployment.

Two 250kWh Hydrogen Power Units (HPUs), supported by battery storage systems, will provide power to major hospitality areas, merchandise facilities, big screens and public spaces around the 15th hole. A separate hydrogen unit will also power the entire broadcast compound, continuing a journey that began with what the DP World Tour described as a world-first sporting application at the BMW PGA Championship in 2023.

The impact is significant. Tournament organisers estimate that the hydrogen systems will save more than 16,200kg of CO₂e compared with traditional diesel generators while reducing emissions from energy generation by a further 600kg CO₂e compared with the 2025 event.

Maria Grandinetti-Milton, Director of Sustainability at the European Tour Group, said:

“We have experimented with hydrogen power at our events for four years now but this is our most ambitious roll-out yet, and the first time hydrogen has been used at this scale to power a major sporting event on a greenfield site.”

She added:

“Getting to net zero is about embracing new technologies and delivering incremental gains year-after-year. I’m excited to see this go live and ultimately share what we learn with other venues.”

Building a More Resilient Energy Mix

Hydrogen is not the only innovation on display.

For the first time, the Genesis Scottish Open will also use solar power to supply electricity to the Fan Village main stage and merchandise shop, while organisers are expanding connections to mains electricity across the site. This includes extending grid power to the broadcast compound and hospitality facilities around the 13th green, further reducing dependence on temporary generators.

The approach reflects a growing trend within sport towards diversified energy systems rather than reliance on a single technology. By combining hydrogen, solar and grid electricity, the event is creating a model that balances innovation with operational reliability.

Connecting Golf and Nature

While emissions reduction remains a key focus, the tournament is also using its platform to highlight biodiversity and nature conservation.

Visitors will be able to take part in wildlife experiences delivered with Zoolab, while a dedicated Nature Trail will showcase the flora and fauna of The Renaissance Club. A Sustainability Symposium involving VisitScotland, Scottish Golf, East Lothian Council and the GEO Sustainable Golf Foundation will also bring together stakeholders from across the sector.

Grandinetti-Milton believes golf has a unique role to play in strengthening people’s relationship with nature.

“Golf tournaments are an ideal gateway for spectators to get out and experience nature,” she said. “We hope fans will leave the tournament with a greater appreciation for how the local habitat blends seamlessly into the spectacular tournament venue.”

From Commitment to Demonstration

The Genesis Scottish Open highlights an important shift taking place across sport. Sustainability is increasingly moving beyond policy documents and net-zero pledges towards real-world demonstrations of new technologies.

That progress is reflected in the performance of the European Tour Group in the recently published GSS SPI Index, where the organisation is currently ranked among the Top 100 most purposeful sports organisations in the world and has achieved a Purpose Established (C) SPI Rating.

The Genesis Scottish Open may not solve sport’s sustainability challenge on its own, but by demonstrating how hydrogen, solar power and nature engagement can be integrated into a major international event, it provides a practical blueprint that others can follow. In a sector often criticised for talking more than doing, that may be its most important contribution.
