Grid can go 75% renewable

Oddly I a making a few bets we will be 7000% ++++ over the grid requirements inside 15 years. Japans hydrogen ship Suiso Frontier built by Kawasaki Heavy Industries is shipping a tiny bit of power from us via its little hydrogen transport capacity. It is a pilot ship. The Japaneses have already plans for much bigger ones and many of them. Global Energy Ventures is a little ozzie ship engineering design company- NOT A STOCK RECOMMENDATION[biggrin]

Japan times "Too cold to handle? Race is on to pioneer shipping of hydrogen." headline is on the money. GEV is chatting about a fleet of them from North West Australia. Japan times is paywalled[bawl]

Energy stores are energy if in the form of batteries, Ccal or LNG or hydrogen or ammonia in a cleaner than green if made with out C02 emissions.


Get the feeling a ship is big? The fleets already exist in oil and gas transport. "Kawasaki aims to build 80 hydrogen carriers to import 9 million tonnes of the fuel a year by 2050, after building 2 commercial-scale ships to import 225,000 tonnes by 2030. It’s targeting overall hydrogen-related sales of 120 billion yen ($1.16 billion) in 2030 and 300 billion yen in 2040. "

80 would just be for Japan I assume[thumbsupbig]

Nothing like an oil burner to ship green fuel [emoji41]

The irony of a little ship was not lost on me[biggrin]. As it is a test for the ultra cold hydrogen transport we can cut them a little slack [bigrolf]

The longer term plan is to power the ship with boil off from the hydrogen liquid.
Just like LNG shipping now which uses the small amount of boiling due to the thermal inefficiencies in the insulation.
I believe the current design operating temp for the liquid Hydrogen is -250 degrees C and the pressure is somewhere in the order of 500 psi.
Given that steel behaves like glass at those temperatures, the mind boggles at how they are going to do that.

Fully agree with the issues at that chilly level. GEV is at a much less of an issue pressure happily. "Germany to tap Australia for 'industrial scale' green hydrogen imports in funding pact planCountries sign declaration of intent that sees Germany co-financing massive renewable H2 plants in Australia using German electrolyser technology"
The headline is not for Germany to give us a excess of hydrogen to use here so we can surmise they want some shipped to Germany [biggrin]
[thumbsupbig] This headline may be of interest "Land Rover unveils hydrogen-powered Defender; commits to zero tailpipe emissions by 2036"

I will be happy to see that one

Great amount of NIMBY by other nations isn’t there.
Let’s cover Australia in Panels and Factories / facilities

this felt appropriate.

Most new global renewable energy projects are cheaper than building new coal generators, study finds. The trends are clear. Its way beyond room for argument.

The Guardian? Again? Is there any point debating with you?

It’ll be interesting to see if companies keep up with the maintenance on wind farms for the long haul. Wonder how many years it’ll be before we’ll see wind generators parked up.

Was at a gearbox engineering shop on Tuesday and they had 3 gearbox’s on the floor, 2 un-repairable. There was also a bunch in the racking which were also unrepairable I’m guessing there would have been six.

They pointed some design issues along with lack of monitoring, preventative maintenance and difficulties replacing a gearbox post commissioning.
