| > So how else we're suppose to interpret this statement: "No, hydrogen rapidly corrodes any metals that it comes into contact with. If they are interchangeable, expect drastically smaller service intervals." I'm not sure why you're having trouble comprehending it. Existing gas turbines are meant to run on either oil or natural gas, not hydrogen. In addition to corrosion, hydrogen burns hotter. You cited one specific turbine model that had a peak hydrogen mixture of 90% (average was 70%). Ignoring the fact that you're picking one specific model that's being highlighted for it's ability to accept hydrogen fuel, this still isn't viable for a carbon-neutral storage system since it still burns natural gas. No, we can't just run them at 90% for years on end because that will still advance climate change. > Either new or existing, this isn't a hard challenge, especially considering we replace old turbines all the time. It's good that you're admitting that it's not a simple matter of modifying existing turbines, and that new turbines have to be developed. But it is an additional bottleneck, it's not just a matter of electrolysis we also have to build the generation infrastructure to turn that hydrogen back into electricity. Likewise if you interpreted my original comment as saying that it's impossible to run a gas turbine with hydrogen that is indeed incorrect. Though I'm rather unsure of how you reached this interpretation given that I even provided an example of a soviet experiment with hydrogen jet engines (albeit with significantly shorter flight time). |
