Re: Hydrogen Production Moving to Mainstream Green solution

Time to board the hydrogen bus, says CSIRO. The report claims that hydrogen fuel will play a key role in the future of transport, and highlights places for governments and industry to focus their efforts.

Australia needs to embrace hydrogen transport infrastructure, according to a new report by the CSIRO.

The report claims that hydrogen fuel will play a key role in the future of transport, and highlights places for governments and industry to focus their efforts.

Re: Hydrogen Production Moving to Mainstream Green solution

The article at the link below contains "forward looking" projections...

https://www.yahoo.com/finance/news/reac … 00528.html

The reason I decided to post the link is that the company in focus appears to be harvesting "free" energy in a clever way .... Aluminum requires a significant investment of energy in order to prepare it for use in products.  As I interpret the article, this company collects used Aluminum that is on it's way to being recycled, and uses the aluminum in an exothermic reaction that produces aluminum oxide. The clever use of this resource gives the company an economic benefit, and it yields a product (aluminum oxide) that is available for input to the aluminum industry, at a cost much less that mined aluminum from bauxite.

Re: Hydrogen Production Moving to Mainstream Green solution

Can China make Hydrogen Electrolyzers cheap as it did for Solar? If it can, hydrogen can replace natural gas, another huge win against climate change.

The answer is 'No', even if they can reduce the cost of electrolysis stacks.  Natural gas is something we extract from the ground.  The energy is almost free.  Hydrogen is something that we must manufacture using expensive electricity.   It could substitute natural gas in limited applications.  But it will never replace all of the functions performed by natural gas.  Most likely, we will eventually rely on it as a feedstock rather than as a direct energy source.

Re: Hydrogen Production Moving to Mainstream Green solution

The answer to Post #53 is most certainly "YES" ...

The key is to use solar power to make hydrogen without using a single molecule of the stored energy Calliban reminds us was stored long ago from solar energy captured in plants, and squeezed by gravity and thermonuclear churning of the Earth's mass.

All that stored energy has given the human race a running start in developing the technology needed for life off planet.  There are no comparable stored chemical energy sources elsewhere in the solar system.  Humans need to learn how to stop living off the egg we've been given.

Fortunately, we have 8 billion people, and of that number, a few are working on developing the technologies we need to live comfortably without drawing upon the chemical stores we've been exploiting.
