Wowow! Hydrogen is coming and peeps all over think it is a dream and not coming...lol. Just wait till a hydrogen powered aircraft or a big train engine is working a route.
There is work underway with the final goal to have the entire city that I live in hydrogen heated and powered. A "Hydrogen Hub" is already underway and the hydrogen generation facilities are under construction. Next is the heavy rail railyard going hydrogen.
There are varying kinds of hydrogen generation. One does use electrolysis and another blue hydrogen is when extracting from natural gas and the carbon is sequestered and injected underground.Not an expert in Energy but an engineer. I wonder what does Hydrogen brings to the table. From what I understand, it comes mostly from electrolysis.. How is the "electro" generated? There is no perfect conversion thus we are left with a product that consumes a lot of energy so that it can produce ... energy? I am lost. Can someone explain this to me?
Peace.
But that's a purely political matter - which we should not discuss here in this forum. The resources and technology are there (for first world countries and we should do everything we can to give poorer countries more time for the transition).Firstly the energy supply must be reliable and affordable to everyone, if not it will lead to civil unrest and all the advances we have made won’t mean anything.
The impairment of power grid stability due to the expansion of renewable energy was and is a frequently used false argument by opponents of renewable energy expansion in Germany.The generation source has nothing to do with electrical grid stability.
The fair distribution of funds for the maintenance of the power grid is a political matter.Seems like a step backwards when you write about the grid system being subject to municipal control. It will turn out to be ‘Every man for himself.’ Wealth in the UK isn‘t spread evenly across the country and if the wealthier parts developed a better electrical supply system it wouldn’t sit too well with me and many others.
I wasn’t even thinking of other countries, all over Europe including the UK there are many poor people, they can’t be left without access to affordable energy.But that's a purely political matter - which we should not discuss here in this forum.

For a municipality, grid stability is the top priority, because only then will new businesses and residents settle - that is one of the reasons for municipalities to operate the power grids themselves again and they are more responsive when the demands on the power grid change due to private photovoltaic installations.
For a private investor, profit comes first. So the the step backwards was to privatize it in the first place
I very much respect your enthusiasm.Wowow! Hydrogen is coming and peeps all over think it is a dream and not coming...lol. Just wait till a hydrogen powered aircraft or a big train engine is working a route.
I'd say the proper analogy for hydrogen as fuel is a battery rather than a primary source such as gasoline. That is, a primary source such as solar, wind, or whatever is used to charge a battery and, by direct analogy, a primary source is used to generate "green", "pink" or "yellow hydrogen by electrolysis.There are varying kinds of hydrogen generation. One does use electrolysis and another blue hydrogen is when extracting from natural gas and the carbon is sequestered and injected underground.
The hydrogen economy is a replacement for train ICE, shipping ICE, trucking ICE etc. Heavy ICE use industry needs a fuel because electricity is not going to work via batteries.
Hydrogen is needed as a raw material for the synthesis of basic chemicals without the industry (pharmaceuticals, fertilizers, dyes, plastics...) cannot produce - see also hydrogen latter.Hydrogen seems like it may help solve some of the timing and energy density issues of solar and wind power. How safe is it really for use in vehicles though?
In the rich industrialized nations, this is "only" a distribution problem - a political matter.I wasn’t even thinking of other countries, all over Europe including the UK there are many poor people, they can’t be left without access to affordable energy.
The power grid itself cannot store energy; for every LED that is switched on, power must be fed into the grid from somewhere.Power grid stability what do you mean by that? The power grid must be able to supply power on demand, regardless of the generation source.
There is no preferential treatment, fees are charged for the use of the electricity grid (7.52ct/kWh net in GER) and the end consumer (i.e. us) pays for it. But the state has to set the legal framework for a fair distribution (how will the revenues be distributed among the operators of the high voltage, medium voltage and low voltage electricity grids).Why would you want municipal authorities to petition the governmrnt for preferential treatment? A formula for ‘Pork barrel politics.’
How is having no money to pay for energy a distribution problem? Unless you are following Karl Marx’s teachings.In the rich industrialized nations, this is "only" a distribution problem - a political matter.

With a few large producers, nationwide coordination is easier than with many independent small producers.
Therefore, the argumentation was that this will lead to a collapse of the power grid - obviously that doesn't happened.

I'm not going to have a political discussion with you....How is having no money to pay for energy a distribution problem? Unless you are following Karl Marx’s teachings.
Who said the grid stores energy? It is merely there to transmit and distribute energy.
To paraphrase a popular sone ‘Those that have will get!’
Canadian company Ballard Power (Which has been working on hydrogen fuel cells in Vancouver since roughly about 1990) supplied technology to a company in Portugal to do what you are describing. Solar to green hydrogen for storage and use during peak demand periods.I think the battery analogy is the best one for hydrogen. There are several posts here complaining about wasted solar and wind when production is high and demand is low. Excess renewable electricity can be used to generate clean or green hydrogen however some more development is needed to improve efficiencies. That said, I don't think a for profit companies like GE and Toyota would spend as much as they are if they didn't believe it was achievable. Not sure we will see it in cars as it has all the distribution issues that gasoline has and which the lack there of makes electric more enticing even if it requires grid enhancements.
I've heard a good many times that intermittent power sources, viz. wind and solar alone cannot efficiently be used to provide grid power. Of course, one solution would be nuclear power. Safe, efficient, reasonably priced nuclear power is possible today far more so than decades ago when the Three Mile Island or Chernobyl reactors where build.Canadian company Ballard Power (Which has been working on hydrogen fuel cells in Vancouver since roughly about 1990) supplied technology to a company in Portugal to do what you are describing.

Portugal switches on first solar-to-hydrogen plant
The Portuguese Fusion Fuel and Ballard Power have announced the successful commissioning of the H2Évora plant on Portugal The grid-connected pilot project will produce an estimated 15 tons of green hydrogen per year.www.pv-magazine.com
