What solutions for long-distance and sustainable transportation ?

Long-distance transport requires power, autonomy, reliability and security of supply. In the context of decarbonization, two solutions or energy vectors are often considered: the electrified road and hydrogen. What are the advantages and disadvantages of these vectors under real-life conditions, and above all, what are their compatibilities with other energy vectors and solutions ? Where do we stand?
