Temasek Foundation has granted $2 million to support the development of sustainable energy solutions in Singapore. The Liveability Challenge 2025 showcased innovative technologies focusing on decarbonisation and creating a cooler earth. Krosslinker, a Singaporean team, offers cooling aerogel paints to mitigate heat, with successful trials showing up to a 30-degree temperature reduction. Ayrton Energy from Canada addresses the challenge of hydrogen storage and transportation, enabling easier adoption of hydrogen as a clean energy source. Both teams aim to scale their impact with the catalytic funding received, contributing to a more sustainable and liveable environment. Krosslinker plans to coat commercial buildings and data centers in Singapore with their innovative paints, while Ayrton Energy's technology simplifies hydrogen transportation through proprietary carrier oils. The focus on sustainability, innovation, and clean energy highlights a positive sentiment towards addressing environmental challenges in Singapore.
