Why not use lecky ? Hydrogen is pretty expensive to produce and to store.
Why not just use electricity.
Hydrogen could be useful for aircraft or off grid situations.
With some nuclear capacity, electric heating makes the most sense. Just let off-peak boilers use that off-peak nuclear electricity.
The problem is, a lot of people want to push 100% renewables.
Solar overproduces in summer and wind has strong days and weak days. Batteries are economically great for short term energy storage (i.e. charging and discharging at least once a day and profiting off of those arbitrages), but they will always be way too expensive for seasonal or multi-day storage. Imagine paying a very cheap $50 for a kWh battery in 2030 and only cycling it 50 times a year. Over a decade, that's an insane 10c per kWh just for the battery, excluding all other generating and financing costs.
The only way out is to have the windmills generate hydrogen on windy days and then push the hydrogen through the old natural gas pipelines.
And you'll have to subsidize it, because economically it will never be very competitive.
Nothing is too expensive. The amount of money that is wasted as astronomical. Think some could be put to good use.
Good fo some things for hydrogen or use those extra days to charge Evs and charge all the home batteries.
Plenty things they could charge
I, for one, am not happy with the way energy prices are going.
Wat too expensive for my taste. A quadrupling in a decade for me.
What are you saying? You want more coal ?.
If the goal is just making heat, there's little difference between the two.
Well now no. That's dumb. I can burn humans to make heat. I can burn coal. The point is the least amount of damage to the planet and the things on it ?
Us
Both are zero emissions. Neither of which does much harm to the planet.
Hydrogen can be produced from fossil fuels though. Unfortunately no way to say hydrogen was produced through green means
That's true of electricity too. There's no way of telling fossil fuel from green electricity.
This is true. Which is why you remove fossil fuels from the grid. Why add extra costs and infrastructure for hydrogen. Just use electricity for heating and hydrogen for planes maybe long haul truckers and sea freight
The infrastructure cost for hydrogen is much cheaper than the cost of expanding the grid. We simply start making a lot of green hydrogen and that will displace fossil hydrogen. Even the grid will rely on hydrogen for backup power generation.
The grid needs upgraded though. So they a moot point. The grid wasn't built for renewables and it wasn't built to deal with the way we currently need it. It's also underdeveloped and underfunded.
So no I hear you disagree.
Hydrogen is expensive to contain and to transport. It has its uses but it's really not necessary. If we use solar and wind correctly. We need batteries. And we don't even need that. We can just use pumped systems and other systems to use power.
Not the case. A hydrogen infrastructure allows us to scale back the grid, or at least limit how much bigger it needs to get.
A lot of the anti-hydrogen rhetoric is marketing BS. We can handle hydrogen just fine. We can even put hydrogen in natural gas pipelines and reuse much of that infrastructure. Also, once we have hydrogen we don’t really need batteries, or at least much less of them. Hydrogen stored in underground salt cavern exceeds the capacity of any other kind of energy storage. So all of the other energy storage ideas become obsolete or much less important once hydrogen shows up.
All electrical grids need to be upgraded. Maybe you could cheap out by doing a smaller upgrade and using hydrogen to offset it. Still needs the upgrade regardless.
The cost of hydrogen is astronomical. It's highly explosive it needs to be pressurized and it's just a bitch. I think you are underestimating the cost of a hydrogen to roll out.
German Japan and Australia have all scaled back. It's mega expensive.
The data on hydrogen gas mix is pretty clear. It's not cost effective and it's a bad idea. Nobody is doing that.
I would love to see that happen. Can you send me a few links on that concept. I've heard of pumped hydro and the crane one. Never seen hydrogen in salt caverns. How would that work for the world? I doubt everywhere has salt caverns.
It's an idea but in terms of logistics. Time will tell
