The aviation industry is facing the challenge of reducing its carbon emissions and reaching net-zero targets by 2050. While there are concerns about the industry's current CO2 emissions and the potential rise in demand for air travel, there is optimism driven by rapid technological advancements and government support. Research from Cambridge University and Aviation Impact Accelerator outlines a roadmap for the industry to achieve net-zero by 2030, emphasizing solutions like reducing aircraft speed, transitioning to sustainable aviation fuels (SAF), and exploring hydrogen fuel cell propulsion. There is a growing consensus on the importance of investing in emerging technologies like hydrogen to drive sustainability and combat climate change. Hydrogen propulsion offers benefits such as zero emissions of greenhouse gases, reduction in contrail formation, and the potential for sustainable production through methods like electrolysis powered by renewable sources. By securing early investments and garnering support from key stakeholders, the aviation industry can pave the way for a sustainable future by embracing hydrogen propulsion.
