Too bad you don’t have any experience in the matter that matters.

And you, James, don’t have a clue as to how any of that happens, because, you, as you yourself admitted, do not have any degree or relevant training in engineering or science. How dare you act like you know anything!

Platinum catalysts are being replaced by similar-performance but cheap materials. There have been several lab discoveries in this area recently.

Also, I am not sure that GE has a “stock”-type PEM. Possibly, their water-based solvents allow for a much cheaper fuel-cell to start with.

There were some words about cost. They estimate, this could be 75% cheaper than current lithium-based batteries.

Good points. I followed the link and the details are very vague; I’m still unsure as to what GE is doing exactly . To just announce they are developing a 75% cheaper, 240 mile battery w/o any real explanation of how is plain silly.

I might be wrong here, but PEMs are still plagued by costly catalyst aren’t they? From the sounds of the hydrogenated fuel description this would still rely on the combining of hydrogen and oxygen in the pem. So while it may have tantalizing wh/kg, no cost was mentioned, and I wonder if they’re using a platinum catalyst or some new doped catalyst.

We built this garbage remarks get old tina. For that matter ‘we’ made the oil industry with subsidies. ‘we’ still don’t have solar panels on the white house 5 years later…and we will see if this comes to fruition.

perhaps robotics could get more advanced. Right now industrial robotics is advancing as fast pace as battery tech.

Right. But many of us are very anxious for some good storage systems to hit the market.

Getting rid of fossil fuels is so close we can taste it. An affordable 180-200 mile battery and a grid storage battery cheaper than pump-up hydro and we’re there.

It’s kind of like when the first affordable personal computers became available. Typewriters and ledger books went away. And the new technology kept getting better and cheaper. First we heard that Woz had made an Apple….

I agree. But some people don’t seem to realize there is a very important process involved when taking an idea off of the pages and into the laboratory, and from the laboratory to the market.

You know that will all the effort being put into finding a good EV battery they will move this along as fast as possible. They might have only a limited window of opportunity to make some money.

At the same time with all the people looking to tear down whatever ‘green’ that comes to the market, especially EV batteries, they will be extra careful before releasing. One whisp of smoke in an extreme misuse situation would ricochet around the web for years.

My guess is that the timing will be just about right.

I don’t see reason why commercialization cannot be fast tracked.

nope wont happen with lithium too labor intensive to manufacture with battery management system. by the way that water will be as heavy but wont give structural support.

range is not the only issue. Floor mounted battery pack made Tesla the best and the safest car ever. Lithium battery is very useful as a support structure and it enables to make better car due to ideal weight distribution.

It is still possible to push down the price of lithium batteries to the $100 per kWh, which is 75% less than todays EV batteries.
