Reply to comment by Sp3llbind3r in Overhyping hydrogen as a fuel risks endangering net-zero goals by filosoful

Driving around a completely seperate, mostly unused engine in a hybrid, which doubles the complexity and maintenance of the vehicle is no more efficient than carrying battery weight. When the number 1 selling personal vehicle in the US (F150) weighs between 4,069-5,697lb, I think it’s fair to say that vehicle weight is not people’s primary concern.

People already have the option to choose lighter, shorter range EVs, but they tend to buy longer ranges due to range anxiety. As EV adoption continues however, a lot of people are realising that they don’t need the extra range and are buying shorter range EVs the second time round.

Combine that with improvements in battery density, improvements in charging speeds, and tech such as wireless charging, battery weights can and are going down.

It’s funny, the anti EV crew claim there’ll never be enough renewables and the pro Hydrogen crew claim there’ll be so much they we’ll have nothing better to do with it than make Hydrogen. In the meantime, rooftop solar and a home battery can cover most people’s energy needs while getting nowhere near what it would take to generate the equivalent amount of hydrogen.

You know, put a small battery in a hydrogen car and make it plug-in or a fuelcell in an electric car.. Drive with the small battery in citys and with hydrogen is for the range anxiety..

I don't get pickups and SUV's at all. Maybe the streets get too bad because nobody with money pays taxes or something.

It will take a while with renewables. And you will have a huge amount of overproduction if you want to power your grid with solar, wind and water. Maybe we figure out better uses.

But the amount of batteries you want to produce is huge and an issue.

Just imagine a houshold with a f150, some kind of sedan and a home battery.

I guess charging whole parking decks of electric cars in citys is not without Challenges. At the Moment it looks like chargers outpace cars by a bit. But that might soon change. If you have to wait to charge somewhere, that gets tiresome soon. Charging at home is the obvious solution. But not that easy to implement in citys.

I'm by no means anti EV. But there are problems that we need to solve. And i don't think we need to replace fossil engines with a single Technology.
