Two start-ups, Krosslinker and Ayrton Energy, have won The Liveability Challenge (TLC) for their innovative solutions to combat global warming. Krosslinker's aerogel-based paint offers passive cooling for buildings, reducing surface temperatures and potentially lowering indoor temperatures by over 5°C, leading to significant energy savings. Ayrton Energy has devised a method to store and transport hydrogen as a liquid, making it safer, more affordable, and easier to handle using existing infrastructure. Krosslinker, based in Singapore, aims to make its aerogel products more affordable and efficient to enable widespread adoption, particularly benefiting industrial buildings like data centers and storage facilities. The company is expanding its product range to include coatings for various applications and is establishing a production facility in Singapore to scale up output. On the other hand, Ayrton Energy, a Canada-based start-up, has developed a chemical process to bind hydrogen with a carrier oil, creating a stable liquid form that can be stored and transported like diesel. This breakthrough method is cost-effective, safe, and can be handled using standard equipment, reducing adoption costs for industries looking to transition to cleaner energy sources. The Liveability Challenge provided both start-ups with catalytic funding to support their scale-up efforts, showcasing the importance of platforms like TLC in nurturing deep-tech solutions for global challenges. The growing interest in climate tech innovation was evident in the record number of submissions received from 100 countries, indicating a strong global momentum towards sustainable solutions to combat climate change and achieve a net-zero future by 2050.
