For example, a breakthrough in better batteries could supplant hydrogen. Better solar cells could replace or win out in this race to the fuel of the future. Those, I see, as the three big competitors: hydrogen, solar cells and then better batteries.
例如，更好的电池的突破可能会取代氢。更好的太阳能电池可以取代或在这场争夺未来燃料的竞赛中胜出。我认为这是三大竞争对手:氢燃料电池、太阳能电池以及更好的电池。
