The article investigates whether hydrogen cars and trucks will take over from electric ones. The researchers found that electric vehicles are advancing rapidly and becoming more affordable and efficient, making them hard to beat. Battery electric vehicles are expected to dominate over hydrogen fuel-cell cars, especially in passenger vehicles. Even with huge charging capacities, electric trucks are more cost-effective than hydrogen trucks, especially for widespread use. Although hydrogen vehicles might be useful in specific scenarios like heavy transport in remote places, they are unlikely to replace electric cars and trucks by 2050.
