Amy Kean, a board member of the hydrogen centre and director of Stride Renewables, said the household batteries would most likely hold up to 60 kilowatt-hours, or about five times the capacity of existing lithium storage on the market. About 130 centimetres high, the size of a small fridge, each would weigh 196 kilograms.
That alone would be a huge plus. Many homes now (including ours) generates far more via solar than we normally use. We do have a Tesla 14 kW/h battery but that's really small (and at $14,000) too costly. The ideal (of us) would be about 30 kW/h.

The main issues with hydrogen are that is very corrosive, and because it is the smallest known atom it will need very thorough containment. This, however, is totally feasible. Many hydrogen-powered cars and busses exist, as do countless fuel cells.
It is virtually inevitable that it will be mostly solar-generated.

Today's Age newspaper...
Germany looks to Australian hydrogen Bevan Shields
Europe correspondent Australian wind and solar farms could help Germany phase out its use of coal under a major export deal that also promises to create thousands of jobs. Europe’s largest economy has identified Australia as a potential supplier of the ‘‘vast quantities’’ of hydrogen needed to decarbonise its heavy industry, adhere to the Paris climate accord and achieve Chancellor Angela Merkel’s goal of net zero emissions by 2050. Research Minister Anja Karliczek said a ‘‘historic opportunity’’ had emerged for Germany to buy hydrogen produced in Australia via renewable energy. It would be shipped to the northern hemisphere using a reconfigured fleet of environmentally friendly tankers.

Methane, CH4, touted in the article is a great fuel. But it contains carbon. It is probably inevitable that the world will either put a price on carbon, or tax carbon intensive imports. China has said that it will buy all of the hydrogen we can make if the price is right. The technology is too new to make conclusions about what the price of hydrogen will be. But there is a lot of private money backing it. Because hydrogen used at low pressure at the point of generation is well under half the price of cryogenic hydrogen delivered overseas, Australia has a huge advantage in energy intensive industries over other countries. We can ship steel instead of iron ore, aluminium instead of alumina and so on. Piping hydrogen al low pressure does not pose metallurgical problems, at least is didn't when I was working with it back in the day. We may be very well placed if the world is serious about nett carbon emissions by 2050. Let's have this discussion again in 20 years time, when I expect there will be a boom market in humble pie.

Part of a December 4th news article...
Back in 2018, Victoria’s Loy Lang coal plant (owned by AGL) made an unexpected pivot to hydrogen. Signing on Kawasaki Heavy Industries, J-Power, and Sell Japan to help AGL turn brown coal into liquified hydrogen that would be shipped to Japan. Last month, more than two years after it was announced, the pilot plant finally came online. A $500 million facility that will burn five billion tonnes of brown coal to produce hydrogen. Which will then in turn be shipped to Japan using the world's first hydrogen transport vessel. A ship that first launched last year.Together, all these pieces will form to create one of the leading hydrogen supply chains in the world. A project that will likely end up becoming a cornerstone of the budding hydrogen industry. As the Financial Times reports: ‘The companies leading the Latrobe project believe it can become a catalyst towards establishing a global hydrogen economy, which is forecast to be worth up to $11tn by 2050, according to Bank of America. ‘The Latrobe plant is just one of several hydrogen megaprojects in the planning or development phase in nations ranging from Saudi Arabia to China and Spain.’ Suffice to say, it’s a huge undertaking. One that seeks to test whether this hydrogen road as they call it is feasible. Both in terms of logistics and cost. But for Australia, it is proof enough that our local industry recognises the need for change.

So we're burning five billion tonnes of coal here in Oz to create a clean fuel for another country....Mmmmm.

Yeah Scotty... I wondered about that too
Maybe the coal can be burned cleanly in the new $500 million facility?
The full news article came to me as an email otherwise I'd post the link as I usually do.

Many advanced nations have committed to net-zero emissions by mid-century and hydrogen is considered a growth industry due to its ability to store clean energy from renewable sources. Federal Energy and Emissions Reduction Minister Angus Taylor said the industry’s potential ‘‘cannot be ignored’’ and argued that Australia can attract $70 billion of investments over the next decade. NERA is federally funded and pools with private business for industry growth. Its chief executive Miranda Taylor said hydrogen presents an ‘‘enormous opportunity for Australia. The world is on a decarbonisation journey and it’s a case of making sure Australia doesn’t get left behind,’’ she said. Companies have been selected to work in the hubs, and will share $1.75 million seed funding. The hubs are designed to gather companies working on new hydrogen technology in the supply chain to drive business growth and innovation. Mr Taylor said the hydrogen industry could potentially reduce domestic energy costs if technological advances cut production costs. ‘‘If we can get hydrogen produced at under $2 a kilogram, it will be able to play a role in our domestic energy mix, bringing down prices,’’ he said. www.smh.com.au/politics/federal/hydrogen-industry-hubs-to-tap-clean-fuel-boom-20210129-p56xxd.html

It sounds good, and a feather in Aust hat for it being on our shore, however, I agree with the comment at the end that it "has been carefully worded to downplay the role of brown coal in the creation of hydrogen". What is happening to the carbon in the coal? Is it still being released into the atmosphere?

Perhaps it is a stepping stone in the development of efficient commercial handling of hydrogen.
