if so, it would be misleading to call it blockchain. All of the benefits of blockchain come from the fact that anyone can participate in maintaining the blockchain -- to forge an entry, a majority of the hardware maintaining the blockchain needs to be controlled by the person wanting to make the forgery. The more unrelated maintainers there are, the harder that is. While there are efforts to design blockchain technologies where private information can be maintained by the public, the technology isn't widely adopted yet.

And because they can be so simple, they are great DIY projects. And if you're not worried about efficiency then you are more free to make the shape visually interesting instead of making the shape purely to extract energy efficiently.

Electrolysis can be used to enrich deuterium. Therefore I could imagine green hydrogen from water electrolysis and grey hydrogen from steam reforming using fossil gas may have different concentration of deuterium. Also steel made using coal and steel made using hydrogen likely will have tiny differences in chemical composition or microscopic structure. Maybe some of these differences could be used to identify the origin steel.

@@miallo (this is a copy of a comment I sent to another user) Maintaining a database can be a lot of work. The blockchain takes the work off the certifying company's shoulders without requiring you to trust additional parties. This is a use-case where the blockchain takes up a lot of the work -- there needs to be a new entry every time any certificate is sold. It also lets there be one global database for all of the certifying companies rather than you needing to work out how to access and interpret the specific database of the specific certifying company. It's also easier to trust a company when there are fewer things you need to trust them with. With the blockchain solution, you only need to trust that whoever mints the certificates is checking whether the manufacturer uses green techniques. With the traditional database, you also need to trust them to track the sales of those certificates. Perhaps the most relevant part: a once-trustworthy company can also become unscrupulous at a later point. They could rewrite history -- saying that a sale didn't happen or that another party had more or fewer certificates than they really did. Blockchain makes it absolutely impossible to rewrite history -- not without controlling more than half of all mining hardware or staked currency on the planet. Transactions are one of the few problems that blockchain has a complete zero-trust solution for. One party mints an entry saying "I offer these tokens to party X in exchange for these other tokens, with the offer expiring at this time", and the other one mints an entry saying "I accept the terms of this entry".

As hydrogen is extremely demanding to store and transport it is very unlikely that green hydrogen becomes a competitive way to store and/or distribute energy except for niche cases. Green hydrogen is very unlikely to become a widely traded commodity. Unless you actually know it originates from some greenwash/PR-stunt you can just assume the hydrogen is "gray", now, and in the foreseeable future. As process input, that's another story. Ore and iron, and ammonia is way easier to store than hydrogen, if production of things like iron and ammonia can be adapted to run based on the situation on the grid, green hydrogen might be able to become competitive. But even in those cases it's premature to build certification systems for the products, we're years and years from getting past demonstration scale production of iron and ammonia with hydrogen. The minute market share that production will have, probably the rest of this decade, can have specific dedicated use, the producers can list the up to a handful of products that the "green" iron or ammonia goes in to. Also, it's not very "green" if the power used essentially is replaced by fossil fuel power, which is the case at least to some degree if you pull power from a grid that has fossil power generation. Oh, but you can have off grid dedicated renewable power generation! Well, you can, but the cost of that has to be added to the overall production cost, and you'd have the issue of intermittency. As long as there's a substantial amount of fossil power generation in a grid, the most efficient way to reduce emissions is to connect more fossil free power generation to that grid, and when there's an excess of fossil free power generation start to replace fossil fuels in cases where it is more difficult to switch.

POS doesn't used raw computational power like POW. It's low energy.

Generating hydrogen, distributing it, compressing and storing it in sufficient quantity is highly inefficient and energy intensive. Hydrogen would be used primarily at the ironmaking stage in the steelmaking process. Approximately 70% of embedded energy occurs at the ironmaking stage. Much better to remove the ironmaking process and concentrate on electrical based steelmaking i.e. scrap. It is more efficient to use "green" electricity to melt scrap than face the losses in a hydrogen based steel process. Australia exports around 3 million tonnes per year of scrap. That is where the answer lies, for Australia at least. I also question how we can operate at night and on low sunlight days.

I am no expert here, but I don't think all Block Chain uses require the same computing power as Bit Coins do, whose computing dificulty is partly due to competition to gain bit coins via solving the algorithm.
