Is there any hope for hydrogen car?













One of the things that I have always been fascinated with about Electric cars, is the talk about how the one thing holding electric cars back from Mass adoption and affordability is the battery. Batteries are expensive to make. batteries are very heavy. The cells that make up a car battery are very finicky and need to be managed very specifically by software. We still haven't entirely figured out how to completely recycle a car battery once it is no longer able to hold a practical charge. although I have to admit that in the last couple of years, the battery industry has made big strides toward beginning the recycling process. Batteries take a long time to recharge. Thankfully the situation has gotten better in the last couple of years, and if you plan it right, you can actually get a significant charge into a battery in a rather short period of time. I'm not talking mere minutes, but definitely under 30 minutes and if you're lucky maybe even 20. batteries aren't as efficient in the cold. This is true both from the perspective of putting a charge into a battery and how much actual capacity is available to be used. With each passing year, new battery formulas and Technologies are discovered which eventually make their way into a car battery. but I'm sure we can all agree that the battery is the Achilles heel of an electric vehicle.

What about hydrogen? If you ask Elon Musk, he wastes no time letting you know that hydrogen is not the answer. But why? if you had a tank in your electric vehicle storing compressed hydrogen, it would be faster to fill, almost as fast as a gasoline car. If you want a longer range, just install a bigger tank. Hydrogen is used in combination with oxygen from the air to create electricity and the waste product is water vapor. it's not extraordinarily efficient, but it's definitely viable. yet there doesn't seem to be a lot of Industry players who are exploring the hydrogen solution. At the moment, the only two car manufacturers that seem interested in hydrogen are Hyundai, Toyota and Honda. So what's the deal? One of the problems has to do with how hydrogen is created. You can make hydrogen using  renewable energy. but there isn't enough renewable energy around to mass produce enough hydrogen to scale up to a car economy. You can also make hydrogen from methane. This is as dirty as making electricity from natural gas, so not very many people think this is the way to go. 

I've never completely lost faith that hydrogen might coexist with electric cars storing energy in a battery, but it's hard to get balanced information about the pros and cons without falling into a rabbit hole owned by the industry interested in promoting or killing hydrogen as a solution. so it was with unexpected and wonderful surprise that I stumbled across this YouTube video, where an unbiased scientist tells it like it is. please enjoy.
