The Benefits of Turning Green Hydrogen into Biofuels
The podcast explores how turning green hydrogen into biofuels, such as biodiesel, is more beneficial for maritime shipping and aviation than using hydrogen directly. For example, it is mentioned that a ton of ammonia fertilizer, which contains hydrogen, can enhance crop yields by 28 tons, resulting in 0.4 tons of biofuel from a ton of biomass. This highlights the significantly higher energy content in biofuels created from hydrogen compared to using hydrogen as is.
