Amsterdam, November 20th, 2025 – Leafcloud, Europe’s first climate-positive cloud provider, will expand its AI capacity in early 2026 with NVIDIA Blackwell RTX PRO 6000 GPUs. This upgrade combines cutting-edge AI infrastructure with the supply of renewable heat. The new infrastructure will deliver more than 1.2 million kilowatt-hours of reusable heat annually to homes and businesses in Amsterdam.
Leafcloud is a Dutch provider of sustainable cloud services whose servers return residual heat to homes and heat-demanding institutions such as swimming pools and care homes. The addition of the Blackwell GPUs strengthens this infrastructure and transforms the heat generated by AI computations from a cost burden into a directly usable energy source. With the Blackwell GPUs, current computing power increases from about thirty to over one hundred and fifty petaflops.
“The paradox of traditional AI infrastructure is that the more powerful the systems, the more energy is wasted on cooling,” says David Kohnstamm, Chief Sustainability Officer at Leafcloud. “Our model flips that logic, ensuring that the heat released flows directly into the heating systems of Amsterdam’s buildings. This allows us to replace fossil energy instead of wasting it.”
The demand for AI computing power in Europe is growing rapidly. The International Energy Agency expects that by 2030, data centers will account for more than one-fifth of the EU’s new electricity demand, with AI representing the largest share. The new GPUs will be distributed across more than fifty locations in Amsterdam and surrounding municipalities. Thanks to local placement and European data storage, all data remains under Dutch jurisdiction.
The rollout begins in the first quarter of 2026, and while focused on the Amsterdam region, Leafcloud sees significant opportunities in other European cities. The company is exploring collaborations with municipalities, housing corporations, and property owners to make the infrastructure available internationally. “Every major European city has two growing needs: more AI computing power and thousands of buildings that need heat,” says Kohnstamm. “The question isn’t whether this model works, but how fast we can scale it to address both challenges at once.”
The new hardware provides up to 1.4 petaflops of AI processing power per RTX PRO 6000 using FP8 precision, offering roughly a forty percent improvement in performance per watt compared to the previous generation. More than 85 percent of the generated heat is captured and utilized through existing building systems.
The enhanced infrastructure supports complex applications. Universities and research institutions can process larger datasets and train more complex models. Healthcare organizations gain access to computing power for medical imaging analysis and drug development. Financial institutions can run advanced risk models and fraud detection, and climate scientists can more accurately model complex environmental systems.
