Zero-emission transportation and aviation through green hydrogen innovation

emerging solutions, green hydrogen stands out especially for hard-to-decarbonize sectors like transportation and
aviation. Sustainable hydrogen originates by electrolysis through renewable energy, providing a zero-carbon
substitute for conventional hydrogen, which is primarily generated by carbon-intensive steam methane
reforming. Hydrogen’s unique properties such as a high energy-to-weight ratio and compatibility with existing
infrastructure make it more than just a clean fuel. It represents a paradigm shift in how energy is produced,
stored, and used. According to the authoritative International Energy Agency (IEA), by 2040, worldwide consumption
of energy could increase by as much as 30 %. Considering this prerequisite with fossil fuels would only
worsen climate change, making green hydrogen not just viable but essential. Despite its promise, challenges
persist. Safety concerns around hydrogen’s flammability have been addressed through modern handling protocols
However, its low volumetric energy density presents storage and transportation issues—particularly in
aerospace. Encouragingly, technological advancements in high-pressure tanks, cryogenic systems, and solid-state
hydrogen carriers are enhancing feasibility and safety.
