Study confirms what common sense has made clear for years: Hydrogen fuel cells cannot catch up to battery-electric vehicles | Electrek

Thanks for that link - an interesting article. Of particular interest for this forum is the piece about ebike (and escooter etc) battery fires which can be found someway down the linked page.

NYC passed a law that takes effect 29Aug23 mandating that:

..... e-bikes, e-scooters, e-mobility devices, and light electric vehicle (EV) battery packs to be 3rd party certified to:

• UL 2849, the Standard for Electrical Systems for eBikes
• UL 2272, the Standard for Electrical Systems in Personal E-Mobility Devices
• UL 2271, the Standard for Batteries for Use In Light Electric Vehicle (LEV) Applications

This will take effect from August 29, 2023, which means that the distribution, sale, lease or rental of micromobility devices or batteries that have not been certified to the applicable UL safety standards by an accredited testing laboratory will be prohibited.

In the first article linked to it says

But when not constructed properly, lithium-ion batteries can result in intense fires. These cases are extremely rare, but the high number of battery-powered devices in NYC has led to a higher number of such fires.

These lithium-ion battery fires are more common when batteries are modified or repaired by untrained technicians, which has become a common practice employed to prevent needing to buy a new and expensive battery. Another factor that has led to some of these fires is the use of third-party and non-compatible aftermarket chargers that can overcharge a battery.

So the new ruling by NYC doesn't seem to apply to battery repair by untrained technicians (DIY builders?) or the sale/use of non-compatible chargers which it says are the main but rare causes of such fires -hmmm!

Well, at least these regs/laws are limited to NYC for the moment at least. Given the amount of headlines that lithium ion battery fires attract both in the press and in post on forums like this, it won't be long before the fear spreads and all sorts of restrictions come our way.

So before you generate unnecessary and eye catching posts about battery fires, think carefully about the consequences of taking this issue out of proportion - just saying.

The main immediate future for hydrogen fuel cell is in powering buses for longer routes as we are doing in London, with other UK cities also now adopting them. The great majority of our London routes are continuing to change from hybrid to battery only operation, this now being policy.

But for cars I agree, hydrogen fuel cell is a dead duck and burning hydrogen directly is unlikely to be adopted.

Tesla's potential new future Model 2 utilising 4680 Lithium-ion batteries - reduced overall vehicle weight with longer range. This is an example, from one company, showing improvements that can being made and will ultimately lead to BEV's capable of many more mile per charge, with reduced vehicle weight, compared to todays vehicles. But we had to start this switch over at some point and that has already happened. We will get there one day but it will take time to shift over from ICE's. There will be issues along the way - not everyone will be happy through the change over period - but I'm sure future generations will benefit greatly. It's the future for as long as we can see and is there to be appreciated. Who knows what lies ahead of this.....?
