Japan Earmarks $107 Billion for Developing Hydrogen Energy To Cut Emissions, Stabilize Supplies (apnews.com) 63

Japan's government on Tuesday adopted a revision to the country's plans to use more hydrogen as fuel as part of the effort to reduce carbon emissions. From a report: The plan sets an ambitious target to increase the annual supply by six times from the current level to 12 million tons by 2040. It also pledges 15 trillion yen ($107 billion) in funding from both private and public sources to build up hydrogen-related supply chains over the next 15 years.

Japan's decarbonization strategy centers on using so-called clean coal, hydrogen and nuclear energy to bridge its transition to renewable energy. Russia's war on Ukraine has deepened concerns over energy security and complicated that effort, but other advanced Western nations are pushing for faster adoption of renewable energy, such as solar, wind and geothermal. So far, Japan is relying on hydrogen mainly produced using fossil fuels.

Japan Earmarks $107 Billion for Developing Hydrogen Energy To Cut Emissions, Stabilize Supplies

  • If they put $107B toward renewable energy, there wouldn't be a gap to bridge.

    The technology exists now. Start building it instead of wasting time and resources trying to develop new tech to solve an already solved problem.

    • That's exactly why they'd need hydrogen for when the sun isn't shining or wind isn't blowing. For this money they could've restarted the existing nuclear plants and built a bunch of new ones.

      • Hydrogen is a shit energy store though. Japan is a mountainous country, so hollow out a mountain and build pumped hydro storage... it would be a better and probably cheaper solution. Japan already has decades of experience building pumped hydro storage, too.

        Again, we have the technology.

            Japan is happy with it because if done right, it doesn't require NEW/Different infrastructure.. Hydrogen packs can be shipped/stored/delivered to anyone/anywhere (using existing infrastructure and Japan has a VERY extensive delivery system already in place for everything from Acorns to Zucchini so what's one more thing?) This is especially important in a seismically active location.

              Also I should point out that Hydrogen (like Nuclear) are both fuels that can be used for space travel.. though hydrogen has a slightly better option for planetary colonization (given outside of Carbon its the second most abundant material in the universe (some estimates put it between 75-90% of all the atoms in the universe are hydrogen atoms in some form).. and again, if done right can be easily harvested without needing a lot of "processing" and "risk".

              So again, their investment has a LOT of applications.

        Yeah, and then you have the waste disposal issues, and remember, Fukashima isn't that long ago..and there is STILL fallout they are dealing with..

        Keep in mind, that unlike the US which operates on a "how will we make money on it" first attitude.. Japan typically understands that if you build it now, understand that the money will come later, but lets not halt progress for the sake of money/ROI. (at least at the government/large scale business level).

        So investing in a proven tech that needs refinement to bring operating/distribution/storage costs down and in-line with "typical" domestic consumption makes sense when you look at the big picture. (waiti

      This is because Japanese car manufacturers invested a huge amount in hybrid systems, but the world is moving to EVs.

      They have whole supply chains making parts for hybrid cars, that are at risk of becoming obsolete.

      Hydrogen is a lifeline for some of that tech, and a new market for Japanese companies. They are hoping that some things will still need the energy density of hydrogen, like aviation and maybe some kinds of haulage.

      • Japan needs a way to import energy from places like Australia, and to store energy for days, weeks or months. Hydrogen can do that.

        That doesn't mean the conversion back to electricity needs to be done onboard passenger cars. Yes they've persisted in that effort far longer than anybody else. But hydrogen-powered power plants for charging battery EV's will also work.

          Hydrogen is a fuel in the sense that once you have some, you use it to fuel an engine or fuel cell. It's not a fuel in the sense that you find it in the environment with stored energy. Perhaps it's most accurate to say it's a fuel but not a naturally occurring fuel? At least, not naturally occurring here on Earth?

          TFA was pretty light on where the electricity for the electrolysis would come from. As are most articles about hydrogen as a fuel.

          TFA also mentioned using ammonia as a way to transport hydrogen without mentioning what the plan was for creating ammonia. AFAIK it's mostly made using natural gas as a feed stock, no doubt emitting CO2 as a byproduct. If I remember, the gist is you strip the hydrogen from the methane molecule then bind it with nitrogen. The left over carbon binds with oxygen to make CO2. I suppose it's conceivable to capture the carbon as soot (or graphite or diamonds) but I don't know if that's actually possible.

              I think when your average person hears "fuel", they think something like wood, coal, natural gas, petrol, uranium. The common characteristics are they all contain bound energy and you find them rather than make them. I realize that's not the definition you'll find in Webster's.

        • The electrolysis process is horribly inefficient. It takes around 60 kWh to produce 1 kg of hydrogen, and only 30% of that comes back when I run that hydrogen through a fuel cell.
