30+ years later we actually have hydrogen motor now but experts conclude that it is not economically viable as a replacement in comparison with EV which is currently the more popular adoption in combination with producing clean electricity using renewable energy.
Anybody has any thoughts on this?
Hydrogen based fuel cells is one such with the bet of the world's largest car manufacturer (Toyota) and will hopefully see increased addoption, unfortunately, because it's not mass produced, it's still quite expensive and unafordable for most of us. Despite the fact that there are very few Hydrogen stations available in practically all the countries.
Meanwhile, for the good and bad, eletric cars with li-ion batteries are thriving, but it's not really a very sustainable alternative due to the materials used to produce these batteries and very low energy density and performance.
