At the moment Max with technology where it is at it is way too costly to produce hydrogen for the thermal output you can get from it. Maybe in 20 years they may come with an answer but hydrogen in an economic form is a long way off.

Yes Norm ,you can't produce enough hydrogen during one day with house solar to get enough
hydrogen fuel to run a generator at night to charge an EV.

I guess the best way would be to charge the EV on the Weekend if it has a range of 1000 km with home solar and no battery.

Hi Max,
Apparently there is some mob in WA who is talking about a 7000 hectare solar farm and so many thousand wind turbines in the hope they can make green hydrogen. Good luck with that

Hi Norm ,

I never knew how many things they can use hydrogen for.

Hydrogen has a range of applications in various sectors, especially as the focus shifts toward cleaner energy solutions. Here are some of the main uses for hydrogen, particularly in the context of a large-scale hydrogen plant:


Hydrogen fuel cells are used in various modes of transportation, including buses, trucks, trains, and even ships. Hydrogen can power fuel cell vehicles (FCVs), providing a clean alternative to traditional fossil fuel-powered vehicles.

Industrial Processes:
Hydrogen plays a crucial role in several industrial processes, especially in:
Ammonia Production: Used as a feedstock for fertilizers.
Refining: Hydrogen is used in petroleum refining processes, particularly in hydrotreating to remove sulfur from fuels.
Steel Production: Hydrogen can replace coke in the reduction of iron ore to produce steel, significantly reducing CO2 emissions.

Power Generation:
Hydrogen can be used in gas turbines to generate electricity, either as a blended fuel with natural gas or as a primary fuel. It can also play a role in grid stabilization when integrated into renewable energy systems.

Heating:
Hydrogen can be used for heating in residential and commercial buildings, either through hydrogen boilers or by blending hydrogen with natural gas in existing gas networks.

Chemical Production:
Beyond ammonia, hydrogen is used in producing methanol and other chemicals, contributing to various industrial applications.

Energy Storage:
Hydrogen can serve as a means of seasonal energy storage. It allows for long-term storage of excess renewable energy, which can be converted back to electricity via fuel cells or combustion.

Carbon Capture and Utilization (CCU):
Hydrogen can be combined with CO2 to produce synthetic fuels or chemicals, playing a role in reducing carbon emissions.

Space Exploration:
Hydrogen is used as a rocket fuel in the form of liquid hydrogen due to its high energy content and clean combustion.

Research and Development:
Ongoing research is exploring new and innovative uses of hydrogen, including its role in synthetic fuel production and in other up-and-coming technologies.

Hydrogen Roadmap: Australia has invested in developing a "Hydrogen Roadmap," which outlines strategies for becoming a major player in the hydrogen industry, particularly in exporting green hydrogen.


Cheers

Hi Max,
They worked out a long time ago that hydrogen is no good for use in air ships

G'day Norm,

Yes Norm, but it was a win win when the Hindenburg blew up as they worked out Hydrogen would be
good for bombs, then later found that the hydrogen bomb has the potential to be 1,000 times more powerful than an atomic bomb.

What I never understood with the Hindenburg is that it didn't actually explode it just burned slowly as it floated to the ground. There may have been an initial explosion but it was the materials which burnt it to the ground

A person would hit the ground from the same height in 4 to 6 seconds the Hindenburg hit the ground in around
30 seconds Norm.

The time that it took from the first signs of disaster to the bow crashing to the ground is reported as 32, 34 or 37 seconds. Since none of the newsreel cameras were filming the airship when the fire first started, the time of the start can only be estimated from various eyewitness accounts and the duration of the longest footage of the crash. One analysis by NASA's Addison Bain gives the flame front spread rate across the fabric skin as about 49 ft/s (15 m/s) at some points during the crash, which would have resulted in a total destruction time of about 16 seconds.

The flames quickly spread forward first consuming cells 1 to 9, and the rear end of the structure imploded. Almost instantly, two tanks (it is disputed whether they contained water or fuel) burst out of the hull as a result of the shock of the blast. Buoyancy was lost on the stern of the ship, and the bow lurched upwards while the ship's back broke; the falling stern stayed in trim
