Innovations Fueling a Greener Future Explored in CNN’s Tomorrow Transformed

CNN’s documentary series, Tomorrow Transformed, delves into global innovations that are shaping a sustainable future. The latest episode highlights advancements in various sectors, including aviation, solar energy, and hydrogen power. This exploration underscores how technology and creativity are redefining industries to address environmental challenges.

Revolutionizing Aviation with Sustainable Solutions

The episode takes viewers to Sydney, Australia, where the University of New South Wales (UNSW) is at the forefront of the energy revolution. The university is renowned for its contributions to solar technology, particularly through the work of Professor Martin Green, recognized as the “father of solar energy.” His innovative PERC Cell design is implemented in over 90% of solar cells worldwide.

At UNSW, Professor Ned Ekins-Daukes and PhD student Jamie Harrison are exploring the potential of thermodynamics to capture energy as heat dissipates from the Earth’s surface. This research aims to enhance solar efficiency and eliminate existing manufacturing bottlenecks. In a noteworthy development, Vince Allen, co-founder of the startup SunDrive, is shifting solar cell production from costly silver to copper, a material that is significantly more abundant and affordable.

The episode then travels to Cape Town, South Africa, where HYENA (Hydrogen Energy Applications) is pioneering the use of hydrogen for energy. Co-founder Jack Fletcher discusses their “Power Pod” technology, which converts available fuels like LPG into electricity through a chemical process rather than combustion. This innovation offers a quieter, more efficient, and environmentally friendly alternative to traditional diesel generators, significantly reducing emissions.

Advancing Biofuels for Sustainable Aviation

The journey continues in Johor, Malaysia, where EcoCeres, a Hong Kong-based biofuels company, is making strides in sustainable aviation fuel (SAF). By re-engineering waste oils from food factories, palm oil mills, and restaurants, EcoCeres produces low carbon jet fuel designed for efficient air travel. The company operates a state-of-the-art biorefinery capable of producing 420,000 tonnes of fuel annually, which is set to power major airlines including Cathay Pacific, Qantas, and British Airways.

CEO Matti Lievonen emphasizes that while the science behind converting waste feedstock into aviation fuel is impressive, the true innovation lies in EcoCeres’ operational model. The company is expanding its influence across Southeast Asia, enhancing its strong feedstock network in China and planning to replicate its successful model in other markets.

In the near future, travelers may find their flights powered by recycled cooking oil sourced from restaurants in Beijing or street food stalls in Malaysia.

As CNN’s Tomorrow Transformed continues to showcase these innovations, it highlights the critical role of technology in addressing climate change and promoting sustainability across industries. The episode aired on December 28, 2025, with multiple showings throughout the day.
