Hydrogen infrastructure

I thought electric fork lifts had removable battery packs. And they had second set of battery packs to charge during the second shift, while the fork lift was still running. Yes a second battery pack was needed but, not a second fork lift for the second shift. Has this changed to non removable battery packs in fork lifts today? Jon

I worked at a newspaper for 30 years. We had electric clamp trucks to move the paper rolls. Forklift with a clamp instead of forks. We had 2 of them in our printing facility and 2 in our remote warehouse. 1 working and 1 charging. No battery swapping.

We also had 40 electric pallet jacks (lift only, manual propulsion). They had to be plugged in after every shift.

And half a dozen electric skid movers. They, too, had to be plugged in after every shift. No spare batteries.

And 3 electric skid wrappers. 1 working and 1 charging. 1 for parts! They weren't real reliable and dock workers often broke them.

I don't doubt you MossRoad, but somewhere in the back of m mind, I remember a factory had two sets of batteries for their fork lifts. I am thinking GM or Alcoa in the 80's, maybe. Jon

Yep. I believe you. Seems like a good idea if it's easily swappable. Looking at ours, they were not.

I don't doubt what you saw. Seems like something some companies would try for obvious reasons. I think we can guess the unintended consequences that might have followed and why it was not adopted as a best practice.

I remember a battery charging aisle with the necessary bridge crane to handle the battery packs. Jon

Hydrogen in compressed gas state is far more dangerous than any of the other potential and existing fuel gases. It also has the problem of short range like propane and CNG. It also requires a heavier storage vessel due to much higher pressures need to keep it gaseous. Real solution to these liquefiable gasses to increase range is to store in a liquid state which to date is apparently not strongly considered viable by the NFPA, ASME, and SAE. Liquifying is several times more costly than gas compression which then requires an expansion system to convert to gas for use in internal combustion engines. These all could be usable in both gasoline and diesel engines which all run on material in a gaseous state when injected into the system. There are many new rotary engine innovations entering the market that have great potential to use these gaseous products. Hydrogen does not release and harmful by products into the environment and have a very low weight to horsepower factor.

In the current economic and existing infrastructure fields electric cars do not seem to be viable. Where is all the additional capacity going to come from? Still has to be fossil fuel today for a reliable market supply. I see a great future for nuclear generated power if we can get the environmentalist to back down. Lot's of luck on that one all the same political force.

My cousin has been mowing with hydrogen for years now. He has it set up to make it as he goes. He said it's dangerous. And if he says it's dangerous....

If you don't mind, could I have his name. I would like to buy a life insurance policy on him. Guessing it's not a sure thing but a lot better than a lotto tic.

Yeah, they are heavy, that's for sure. We couldn't change ours. When they'd no longer take a charge, we traded in the clamp trucks for new ones.
