The Cooling Challenge

Today, cooling consumes 25% of electricity generated worldwide and is responsible for 7% of greenhouse gas emissions. Cooling has become critical to our everyday lives. It is quickly becoming a basic need — required to create  comfortable climates for living, to bring food to our tables, and to keep the internet running. The rising middle class and continued growth in urbanisation is expected to increase cooling demand. If left unchecked, the electricity used to power cooling systems will overburden electrical grids and increase plant-warming emissions.

The cooling Challenge

Our Mission

At SkyCool Systems, our mission is to deliver sustainable, energy-efficient cooling solutions to customers interested in reducing energy costs and carbon footprint.

Our Story

SkyCool was founded in 2016 on the premise that cooling systems play a large role in contributing to climate change. Additionally, as global air temperatures rise and summers become hotter, energy use for cooling will grow significantly.

Our aim is to improve the efficiency of all cooling systems by harnessing an untapped renewable resource: the sky. We are dedicated to using our technology to bring efficient, climate-friendly cooling to all parts of the globe.

Our Vision

SkyCool’s vision is to bring electricity-free cooling to the world
