The Tokyo Metropolitan Government is doubling its budget for hydrogen-related initiatives from fiscal 2024, seeing them as key to combating climate change. While previously supporting fuel cell vehicle (FCV) purchases and the establishment of hydrogen fueling stations, the focus is shifting to promote the adoption of hydrogen fuel cell-powered commercial vehicles including large trucks. Will this be a catalyst for the widespread adoption of hydrogen?
But they’re about three times more efficient so even if the electricity is made from fossil fuels they’re better.
This is more anti-hydrogen propaganda. If both are made from fossil fuels, the carbon intensity is basically the same.
I genuinely don’t know what to say. Maybe you should try to develop some basic understanding of the subject matter before embarrassing yourself with such hot takes. If one vehicle is more efficient than another, it obviously requires less fuel to travel a certain distance. That means less carbon emissions because less fuel is being burned. I don’t know how I can dumb it down any further.
Again, straight-up BS. People are blatantly lying to you about this subject. BEV companies are spreading nothing but propaganda. It is a factually false claim.
In fact, it can easily be demonstrated to be the case. You generate 9.3kg of CO2 per kg of hydrogen when made from 100% natural gas. At 70 miles per kg, that is 133 grams per mile.
Meanwhile, electricity from natural gas generated 0.86 pounds, or 0.44 kg, per kWh. At 3.4 miles per kWh, that is 129 grams per mile.
That is within spitting distance of each other.

Oh OK. And then the hydrogen is teleported straight to the car’s tank, right? Fantastic technology! Ever heard of well to wheel efficiency? For BEVs that’s generally accepted to be around 70-75%. Die FCEVs it’s more like 25-30%. Go figure.
Hydrogen pipelines are a lot cheaper and simpler to build than high-voltage powerlines.
And you are just ignoring what I just wrote and substitute outright lies from BEV companies. Again, there is no difference in CO2 emissions when both are made from fossil fuels. As a result, BEVs are not any greener and arguably much worse when you look at certain factors related to weight and battery production. The entire argument over efficiency is just a extremely rare scenario which doesn’t even apply in this case, and won’t apply even in the future. In reality, you will need to store electricity in a 100% renewable grid. That requires large scale and long-duration energy storage solutions. One of which is hydrogen based energy storage. So you will charge your BEV with hydrogen power in the future. This quickly kills the idea that BEVs are anymore efficient.
And that is before you factor future innovation. In the long run, we will make hydrogen directly, such as from photocatalysts or thermal processes that don’t use electricity. Fuel cells will increase in efficiency until they are basically the same as conventional batteries. As a result, this entire argument will be totally rejected. It will only be remembered as this BEV propaganda statement from the early 21st century.
Nice gish gallop, mate. You’re really a lost cause.
You are projecting. You are the one spamming BEV propaganda. You are the one repeating lies. People like you are nothing more than climate change deniers and allies of corporate interests.
