Out of a Hong Kong university laboratory, a small materials science company has found a way to let buildings, vehicles, and machines shed heat by whispering it into space — no electricity, no refrigerants, no moving parts. i2Cool, now four years old and operating in more than thirty countries, has secured Series B funding from TopoScend Capital to scale what was once an academic curiosity into an industrial force. The investment arrives at a moment when the world's hunger for cooling — driven by AI, electrification, and a warming climate — is colliding with the urgent need to consume less ener

Renewable energy and energy efficiency
Consumers could benefit from lower electricity bills through reduced cooling costs in homes and vehicles, decreased reliance on traditional air conditioning systems, and improved thermal comfort without additional energy consumption. Long-term adoption could reduce household energy expenditures significantly.
Governments may incentivize adoption through energy efficiency rebates or building codes favoring passive cooling materials. Potential regulatory frameworks needed for nanoparticle manufacturing standards and safety. Could influence climate policy by reducing grid demand and supporting decarbonization goals.
