Our Mission.

Turning Heat Into Harvest

We use waste heat from data centres to power vertical farms that grow medicinal plants, helping build greener, circular cities for the future.

The Hot Air Company is a climate-tech social enterprise transforming urban waste into agricultural opportunity. Our mission is to help cities become regenerative and economically viable by connecting two major urban pain points — energy waste from data centres, and the environmental cost of imported crops. Sustainability isn’t a cost — it’s an advantage. We're here to make it scalable, circular, and profitable.

Building Sustainable Cities is Good Business

What
We Do

Circular systems powered by purpose capture excess heat from data centres and redirect it to local vertical farms. These controlled environments grow medicinal plants for healthcare, pharmaceutical, and nutritional use — reducing the UK’s 96% import reliance while cutting carbon emissions. The system enables lower cooling costs for data centres, local and ethical crop production, year-round growing with stable climate control, and new income streams aligned with ESG goals. This is about more than cutting carbon — it’s about closing the loop.

How
It Works

Waste heat from data centres—often exceeding 40°C—is captured using custom heat exchangers and redirected through insulated pipelines to nearby vertical farms. There, AI-managed environments harness the heat to grow high-value medicinal crops under optimal conditions. Harvested plants are supplied to NHS providers, pharmaceutical companies, and herbal suppliers. Any residual heat is reused, completing a circular thermal ecosystem. AI is hot right now — literally. That heat fuels growth.

The
Future

Building the world's smartest vertical farm means developing a research-driven facility and software platform to optimise growing conditions for a wide range of crops. The goal: to create a global plant knowledge base and a scalable heat recovery model that can empower vertical farms around the world.

Why this matters: by repurposing data centre heat, the system can save up to 30% in energy costs while cutting emissions from food and pharma imports. It supports resilient, local healthcare supply chains, builds green infrastructure, and helps create circular economies. Ultimately, it enables a new model for regenerative cities. Cool cities start with smart heat.
