2 Thinks! First, my wife has chemical sensitivities so I made a hydrogen cook stove (Hindenberg I with modified natural gas range) and we cooked with H2 for years. The off-grid PV system electrolyzed water and stored H2 gas in an inverted barrel in a larger water filled barrel using only the pressure from the alkaline electrolyzers. We also purchased bottled H2 gas. Results are the chef-preferred "cooking with gas" but with no CO, CO2 pollution. Second, consider "H2 gas blending with CH4" at the home / business. Solar electrolysis H2 combining with natural gas at 10-20% H2 blend can be easily used in all gas appliances with no modifications. Reduced carbon and uses renewable energy to displace fossil fuel for distributed solar fuel at the point of use in residential, commercial and even industrial processes.

This is the first application of the hydrogen cycle that has an overall efficiency that I find palatable.

[@mrhickman53]

@bk_16 Fair enough. I am also sceptical but they have at least piqued my interest. My impression is that batteries will win the daily cycle but if the company can provide a cycle efficiency of close to 50% I would at least entertain the idea of incorporating such technology for longer outages. For areas that regularly have winter storm-related outages, coupling the waste heat energy into the home would improve overall efficiency The conundrum is that at the current price, several days worth of battery storage is economically competitive. Once one goes to 1/4 charge/discharge cycle per day the battery lifetime is approaching comparable performance to what the company is stating for the fuel cell. My desire to see at least 50% cycle efficiency is the collected solar energy is better sold to the grid than be used in a low-efficiency storage mechanism from a global warming perspective. We should prioritize more efficient processes until renewable energy has expanded to meet our full energy needs.

[@jonmichaelgalindo]

I'd like to be hopeful, but realistically, batteries are just getting better and better. They're already cheaper, with better efficiency, and they'll have longer lifetimes soon enough. I just don't see hydrogen technology catching up.

Good to see that there are arising so many options to store hydrogen

[@idea-shack]

Hydrogen storage in metal hydrides has been around for decades, I've even seen a large system personally in use at my university about a decade ago, feeding PEM fuel cells. This Lavo unit is just a sexy commercial version of very well established tech. The more important question is, why if it's been around for so long, has it not been widely implemented? Probably because fuel cells are generally considered as being too expensive to be practical at the moment, however, if they do become more mainstream, then hydrogen storage in metal hydrides would probably be the preferred choice imho.

[@marclawson2536]

Technology is only considered advancement when it serves capital. "Where will we put our meters?"

[@RoadRashSpirit]

My basic understanding of the metal hydride system is that it requires a high temperature to get the hydrogen back out again, which obviously uses energy which has to initially come from somewhere and will further reduce the efficiency of the whole system. For this reason it is un attractive and I do wonder if LAVO has a new chemical composition that mitigates this. There seems to be no mention of this so if I was a betting man I'd say not, luckily I'm not a betting man and I will watch this space over the next ten years.

[@acmefixer1]

@Nicola Toma The Gencell hydrogen fuel cell system can use ammonia for storing the hydrogen. The byproduct is nitrogen which makes up 79% of what we breathe. And the infrastructure for making ammonia is well established and produces huge amounts, but not green.

[@travcollier]

Yes, but that well established tech is optimized for different use cases. The landscape has shifted quite a bit with wind and solar costs coming down, so development of versions optimized to serve as "batteries" for that makes sense... And that sort of development/optimization isn't easy. I think where I've heard most excitement interest in metal hydride hydrogen storage in the past was around transport/cars. This application makes more sense to me, though I'm not certain about the fuel cell side of it.

There are some complex arguments in this proposal - and it has been on the cards for a while. As a solar owner I was initially frustrated by this.

I have heard arguments that we are effectively using an extant system to sell our produced solar and expect to be able to do so without incurring costs. My response is that the feed in tariff is lower than the purchase point which should be covering this cost. I think real and significant issue is bigger than all of this. Its that NSW State Govt could see the writing on the wall and sold off the poles and wires a few years ago to avoid it being their problem - consequently the private industry has not invested and now we have a grid incapable of dealing with the burgeoning solar during the day and supply everyone during the night (I say this as a layman and am happy to have further explanation provided to me).

So, I might be wrong here, but in addition to being more than double the cost of a tesla power wall, wouldn't you also need to double your solar capacity in order to make up for the 50% efficiency rate? I think that needs to be considered as part of the total cost of ownership for a system like Lavo, since it's roughly 50% less efficient than the battery.

[@ivobrick7401]

It depends how much time are they able to hold power, even inefficient one. If you have double the power you need from your solar, let's say you use 2MV / year, you will need 4kWp solar array - that will cost you 149 eur / per 330 Wp panel, that mean little under 900 eur total (adition to your power plant). Also, need to know other things like max charging capacity of those new LAVO battery etc.

While much of this is interesting, i could not help but notice a significant and unwarranted degree of implied negative bias towards the fossil fuel industries. But that is likely due to my 40+ Electrical engineering career serving a broad range of energy industries beginning with hydro and CANDU fission nuclear and ending with oil and natural gas industries with some PV solar and environmental soil remediation tossed into that mix. The devil is in the details and who could know better than the energy industry engineers who struggle with intense laws of physics, economics and budget constraints 24/7/365 days a year. “Its not so much what we don’t know that gets us into trouble but what we know for sure that just ain’t so!” - Mark Twain.....and “It is much easier to fool someone than it is to convince that person that they have been fooled!” Consult any electrical engineer who has worked in a variety of energy related industries to gain a more thorough and indepth understanding of the transition challenge ahead....preferably one who is retired as those who are still working know enough to remain silent when their career could be on the line for speaking against an obviously bad energy concept......

another high quality well researched episode I did examine this domestic Lavo unit, but with the 50% round trip efficiency; costings came to $30,000 AUD for "stated" 20kWh storage, BUT on closer examination and reading past the fluff of the headline copy only getting half that. Works out to be $30,000AUD for only 10kWh, far far more expensive and huge bigger bulkier unit. So opted for 2x powerwall 2s, coming in at $24,000 AUD and proven TRUE 27kWh; to completement the current 11.88kWh reidental solar, excellent (so far).

The perfect home hydrogen fuel cell would get its water for electrolysis from rain water barrels, use excess solar power to convert the rain water to H2. The hydrogen fuel cell can power the house at night and warm the house during winter and run AC units during the summer. The fuel cell’s water byproduct is undrinkable without processing; you can either use that water to keep radiated heat pipes full, or filter/mineralize/soften the water for drinking. For me, I’d like to use a CO2 scrubber to turn the fuel cell’s water to soda water. Unlimited vodka club.

What a long way we have come since I powered my home when I lived in the middle of nowhere in Australia when I had a couple of solar panels, a wind turbine (it was very windy up there in the Victorian high country) two second hand batteries and an inverter. The fridge and stove ran on bottled gas, the lights were 12 volt so the cottage was wired for both 240 and 12 volt. It was quite high maintenence but no power bills for the 15 odd years that I lived there. Gas bottles weren't that expensive in those days and I didn't need all that much.

I am disappointed in this channel. Jacobson deserves the patent for 'fake news' and is a complete nutter. And the ideological critique the author offers for seeking to dismiss hydrogen from natural gas with or without carbon capture and storage on the grounds that the fossil fuel industry is using it as a ruse is comparable to a marxist notion of 'fellow travellers' Numerate critiques look at the numbers. Hydrogen obtained by reforming for use in home fuel cells, as they do in 300,000 homes in Japan, means that the heat can be used for hot water, instead of vented to the atmosphere as present gas turbines do. So something of the order of a 30% improvement in energy utilisation and consequently fewer carbon emissions is dismissed as not ideologically pure enough. And some carbon capture methods result in solid carbon, for easy sequestration, and also industrial use. Ideologues banging on about their hobby horses without a real understanding of the technologies or a sensible numerical evaluation of options are part of the problem, not the solution.

[@xijinpingpong4426]

The high energy prices in Europe are mostly a result of renewable energy that won't be stored for times with no sun and no wind. So the old infrastructure is still there for this times and gets maintained. The old infrastructure produces less and costs nearly the same. At the same time more wind turbines and solar panels get build without building enough storage systems. The renewable energy gets highly supported by the state. Building storage systems is expensive and the old infrastructure is already there. So it is at least in most of Europe a result of energy politics and not of the "bad" private companies.

I remember a demo where an incendiary bullet was fired into a container of a gallon of petrol (very big bang), and a charged metal hydride container (total anti-climax and little or nothing happened). Unfortunately, at the time, hydrogen was used as a combustion replacement fuel, so I guess this is why it never took off as there were significant problems using hydrogen in an internal combustion engine.
