Life-cycle1 water consumption of fuel cell electric vehicles using hydrogen produced from natural gas with steam methane reforming is almost 50% less than the life-cycle water consumption of conventional internal combustion engine vehicles using gasoline. If the hydrogen is produced from solar power and water, the life-cycle water consumption is almost 60% less.
