Hydrogen is the stupidest, most ridiculous, and most impossible energy alternative. It takes 5 to 10 times more energy than it returns. This has been known since 2004, yet hydrogen refuses to die.
It is far from renewable because it contains no energy at all—energy must be forced into it like a battery—and you lose even more when converting it back to electricity. It has the worst energy return of any alternative: far more energy goes in than you ever get back.
Consider the process: you first split hydrogen from natural gas or use far more energy to electrolyze it from water, then compress or liquefy it, build extremely expensive and short-lived steel containers and pipelines (since hydrogen embrittles them), and finally deliver it to virtually non-existent hydrogen vehicles. Fuel cell technology remains far from commercial.
It is also highly explosive. Hydrogen requires 12 times less energy to ignite than gasoline vapor, so the smallest spark or heat source can turn it into a bomb.
