Green hydrogen's time has come, say advocates eying post-pandemic world

So long as the hydrogen is produced using clean, renewable sources of energy.

Our house produces over double what we use. With the right technology and proper support and commitment from goverment, houses such as ours could be used to power mini hydrogen producing units.

But cost and efficiency of the technology needs to match other clean technolgies..

It sounds like the key technology is to make hydrolysis more efficient, admittedly by a large chunk of 10% or so.

More efficient hydrolysis means intermittent green energy can be stored for when its needed and the sun is not shining.

Hydrogen would be a good fuel for ships, which currently run on super dirty fuel oil.

Regardless of how it's made though it's a universal solvent, meaning it corrodes the containers that contain it, and you were better off with the electricity directly.

Completely FALSE.

Hydrogen is not corrosive it makes metal brittle, Toyota had already provided the solution by making the Hydrogen fuel tank for the Mirai FCVs out of Carbon Composites.

Hydrogen does not attach itself against Carbon.

Hopefully a better idea than wind turbines and solar panels that often destroy large natural areas

I think it will be wind turbines and solar panels that provide the electricity to produce the hydrogen.

you don't need to make it as it's not safe. Nothing you have runs on hydrogen. Electricity is the mediator of usage and our systems can use that now. No changes need occur to any building or system across the country.

Made hydrogen once and the energy losses were very substantial. It was far far better to keep the electricity rather than dealing with the conversion losses. It's doesn't scale to the home you need large plants or large transportation for it to work out. Homes though do scale with renewables. It's possible to be net zero or even net negative. Excess can be put back into the electrical grid as well.

In theory, there's no difference between theory and practice. But in practice, there is!

Don't need to waste water. Sunshine and wind. Then there are the thermals, heliothermal, geothermal, hydrothermal. You don't use up anything. You take away land, there is still land there. You cannot lose it.

We go from a mindset of scarcity using things up, to a mindset of abundance using various potential differences without depleting

Hopefully a better idea than wind turbines and solar panels that often destroy large natural areas to install expensive non recycled oil produced panels and giant turbines that requires millions to maintain and then also become toxic waste when their life cycle ends.

hydrogen is usually green washing for the fossil gas industry. Regardless of how it's made though it's a universal solvent, meaning it corrodes the containers that contain it, and you were better off with the electricity directly.

Hydrogen was abandoned by every car manufacturer as impractical.

Everyone's going with EVs. Hydrogen is a money loser

Don't waste your time with hydrogen. Follow the money and you'll find the dying oil and gas industry

Look at the players. Limited large companies, same old distribution systems and partners, gas stations, you have to go out. Same paradigm of systems, limited players controlling the market. Safety is questionable. They set the price.

Look at the disruptors. Massive home solar, powering local grids, grid connected vehicles, safety from others. New paradigm of players opening the market without needing to regard for the resource. Resource price is zero, only cost is collection and distribution. Safety is never an issue so not a cost either. Price is set locally.

When you no longer own the land or resource then the paradigm shifts. When the resource is free then cost is only in collection. Everyone is then just a distributor as costs drop. They never have to research and develop something they don't need. Making them winners.

All the disruptors ruin the business models of the inefficient subsidy based corporations. Countries put in thousands of recharging stations. When they finally drop the oil/gas subsidies fall oil/gas companies will never be economic ever again.

Countries are going to want to keep that clean air they see today. Cuts pollution hospitalization and saves money. Makes nations more resilient and not dependent on someone else setting the price.

Fossil gas is just another way to stay dependent on the same players. We leave hydrogen we really go green and the economic facade finally drops in favour of local economies.

Again NOPE.

The difference between Hydrogen and Carbon based energy is, Carbon based energy is dig up from the land so land owners are the ones that get rich.

Hydrogen can be generated basically anywhere with enough water and electricity.

It levels the playing field where anyone who is willing to invest in the infrastructure will be able to generate it.

You can do it at your home by connecting the solar panels on your roof top and water from tap and capture the hydrogen generated through electrolysis or obtain those artificial leaves that have been recently developed and create your own Hydrogen farm.

The only thing you need is a body of water and sunshine.

What also kills hydrogen is Dr Goodenough and his lithium battery inventions. He has since invented the successor to that as well the solid state battery. Storage is feasible today with lithium ion but that is dependent on available lithium. Tesla home systems are currently in use. That will only get better as Goodenough inventions are developed, and use fewer exotic materials. Lithium battery already killed hydrogen, the new fast charging ability of his new invention will bury it further

That continues to mean no hydrogen.
