Why HN links it
HN commenters cite Spectra by MHI posts on hydrogen, turquoise hydrogen, ammonia fuel and salt-dome energy storage. The comments use them as supporting links for their own points on energy topics.
Summarised by Claude from a sample of 5 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Spectra explores innovations, trends, and expert insights driving progress in energy, industry, and sustainable technology worldwide.

As an example, consider this story out of Utah: https://spectra.mhi.com/hydrogen-and-salt-domes-are-winning-... A single cavity in that salt dome can store 150 GWh of energy, and there's room for 100 cavities.

HN discussion> If it is produced from e.g. methane (the blue version), then we are burning more methane than we would have if we had been using the methane directly Yes, but since we're capturing the CO2, that's fine. There's also turquoise hydrogen [1] - produced from natural gas by pyrolysis, capturing solid carbon, without ever producing CO2. This is equivalent to blue hydrogen, but the technology looks a lot more promising t…

HN discussionThere are two reasons why Toyota is pursuing hydrogen. First, the well known short comings of BEV as often pointed out on HN. The most common is range anxiety (dead electric car) and how long it takes to recharge (30 minutes at a quick charging). With a hydrogen fuel cell vehicle, it has a higher energy density so its range is farther and it takes about 10 minutes to fuel up a Toyota Mirai with hydrogen. This is the…

HN discussionIt gets thrown in the bin. That is, if you've made the hydrogen by pyrolysing natural gas, using a process which separates the carbon as a solid: https://spectra.mhi.com/achieving-net-zero-what-is-turquoise... You might even be able to sell some of it, although i suspect there isn't a market for all the carbon you would produce.
