UPDATE: CNN’s groundbreaking series, Tomorrow Transformed, has just released an urgent episode highlighting global innovations that are reshaping our commitment to a greener future. As the world grapples with climate change, this episode showcases vital advancements in technology, including sustainable aviation fuels and revolutionary solar energy solutions.
The episode, airing on December 28, 2025, features key developments from around the globe, specifically focusing on how businesses and researchers are actively working to create a cleaner, more sustainable world. Viewers are taken on an eye-opening journey from Sydney, Australia to Cape Town, South Africa, and beyond, illustrating the critical role of innovation in addressing environmental challenges.
In Sydney, the University of New South Wales (UNSW) is leading the charge in solar energy innovation. Home to the esteemed Professor Martin Green, known as the “father of solar energy,” UNSW is at the forefront of photovoltaic technology. Professor Green’s PERC Cell design is now utilized in over 90% of solar cells worldwide. Alongside him, Professor Ned Ekins-Daukes and PhD student Jamie Harrison are pioneering new methods to harness energy from the earth’s surface, pushing the limits of solar efficiency.
Meanwhile, in Cape Town, the startup HYENA is redefining the use of hydrogen as a clean energy source. Co-founder Jack Fletcher discusses their innovative “Power Pod” technology, which transforms hydrogen into electricity through a chemical process. This method promises to deliver a quieter and more efficient alternative to traditional diesel generators, significantly reducing emissions.
The episode also highlights EcoCeres, a biofuels company based in Malaysia that is revolutionizing sustainable aviation fuel (SAF). The firm is producing advanced, low-carbon jet fuel from waste oils sourced from food factories and restaurants. CEO Matti Lievonen emphasizes the importance of their system, which is projected to produce 420,000 tonnes of eco jet fuel annually, supporting major airlines such as Cathay Pacific, Qantas, and British Airways.
With these innovations, the potential for a sustainable future is more tangible than ever. The episode’s revealing insights not only highlight technological advancements but also underscore the critical collaboration needed across sectors to combat climate change effectively.
As the world anticipates the future of energy, Tomorrow Transformed serves as a clarion call for immediate action and innovation. As viewers tune in, they may soon find that their next flight could very well be powered by recycled cooking oil from a local restaurant, showcasing the real-world impact of these advancements.
