The Future of Energy Storage Could be Hydrogen
Вставка
- Опубліковано 23 січ 2021
- To get off the grid with solar and batteries, you need to be able to generate energy when the Sun's out, and store it for when it's not. Right now, people are able to do this with lithium-ion batteries - Tesla's Powerwall 2 is a perfect example. But Australian company Lavo has built a rather unique cabinet that can sit on the side of your house and store your excess energy as hydrogen.

The Lavo Thunderdome, two joules enter, one joule leaves!
seems like they're under-capitalizing on the main advantage of hydrogen here by making it an all-in-one product, if they split it into three or so components, ie. electrolyzer, fuel cell, and storage tanks, then customers could have more flexibility to decide their own trade-offs for maximum power input, maximum power output, and total stored energy
in particular, I'm sure that $/kWh figure would scale really well if you could just buy more and more tanks, and scale up to a week or two of storage capacity if you wanted, without having to buy more fuel cells or electrolyzers, which are likely the more expensive bits
wouldn't really be a suitable "off the shelf" solution
New power stations are equipped with plug and play extra storage. On another note, is the oxygen from the electrolysis just thrown away? Maybe it can be burned to run a small turbine.
i see what you are saying. but then what you want is an all in one with the ability to stack more storage. it seems as if you were suggesting that they give people the option to buy their own fuel cell or electrolyzer. i doubt anyone wants to do that.
I totally agree, of course this might need software optimization, but yeah, is a great idea.
For example is a shame this system requires an extra inverter, because the solar panels already need to pass over 2 inverters to reach the electrolyzer.
Not sure if they use the heat loss from the fuel cell mode in some way, a good way would be to produce hot water for the house, or maybe they use to improve the efficiency of the electrolyzer or in the metal hydride tanks.
Scaling storage on hydrogen should be incredible cheap, but maybe is not so easy if they really use the waste heat to improve the efficiency of those systems.
Maybe a future product could be a lego of different hardware modules to improve utility.. But this only may happen when they already sell at least 5000 units of each piece of hardware.
Roy, you can't "burn" pure O2. Oxygen is an oxidizer, not a fuel.
I hope the prices comes down to be in the reach for a common man. I love the concept.
I really hope to see Green H2 /Fuel Cell to be used in aviation and see a parallel H2 economy thriving along with BEV.
@Michael don't go out in the Sun, your brain might lose lose those brilliant streaks of thought. Good luck.
Excellent low pressure storage system wiy hydrides ! Thak s for this video
You forgot to mention the cycle rate.
Lavo has 20 000 cycles vs Teslas 3 000.
That's 800 000 vs 40 000 total kwh.
Even at 50% efficiency Lavo, and you have no space constraints, Lavo batteries are easily the best option. This is not not antiquated lead-acid battery technology, nor is the hydrogen in a dangerous compressed or frozen state. It is safe and very green ... except for the lithium battery it has for immediate power. lol.
yes. he forgot to actually do the calculations. i think he said 30 years which is 10k cycles. i think if you do the math a 3x lover cycle for 3x more price makes it the same as tesla power wall. but then LI batteries are getting cheaper every year so you’ll prob want a newer better cheaper LI power wall in 10 years. but it’s nice to know that hydrogen is getting closer, especially for home and grid storage.
Wish they could develop the tech for low cost grid scale storage, and ultimately ships and planes later
Hydrogen can be stored for a long time before use in comparison to batteries. Thats where even though efficiency is less. The fact it can store production energy in summer for use in winter exceeds what a power wall can offer for solar power storage and use timeline
Excellent video and pick again.... But No way to find any information on long term storage leaks. If I charge in the summer and use in deep winter +/- 6 months later, how much capacity will have been lost. On every day usage batterie may be a lot more efficient but yet their phantom drain (1% to 2% capacity loss per 24h day idle typically in my Tesla Model X) and limited capacities make them irrelevant to pass the winter peaks in an off grid use case ....
Hey, great content man, would be nice if you had a teleprompter.
Am I correct?
In the specs the unit is rated at 40kWh, yet with the conversion H2 to electricity being at 50%; giving a true storage (electric equivalent) of 20kWh.
So costing $AUD 30,000 for a 20kWh of electricity system.
Wouldn't they rate it by energy out instead of energy in?
How much soler would i need to support this system?
Maybe it is not that efficient but it looks far more eco friendly then lithium batteries.
This is interesting.
What type of hydrogen electrolyzer does it use??? Alkaline solution or PEM?
Iam australian why have I not hear of it well done little austy
the company has been promoting the unit through the trade journals and environmental periodicals since late last year
Because energy is more a political matter than technological
I will go with my original idea....a 30kW solar array and a PWII...Thanks for the video
He failed to mention the cycle rate.
Lavo produces 800 000 total kwh over it's life time ... versus Tesla's 40 000. Hmmmm? Now which battery is the better option? lol.
And Ford should give the Aussies a call about the battery tech ... for a hydrogen fuel celled version of the F150 Lightning ... and work with Lavo selling their residential & commercial units throughout North America. Charging stations for hydride batteries that you can plug into any Unit, machinery or vehicle. Hmmmmm?
Some pretty big claims here. But if it works as advertised AND last 30 years, at $22,000 it's a much better deal than a Powerwall. Who cares that's it's inefficient, it still has huge capacity, you would need 3 Powerwalls to match it. Can't wait to see the reviews on this.
not quite
@@Leopold5100 You want to explain that? At 3 times the capacity and only twice the cost of a Powerwall how is it not a good deal?
It has 20 000 cycles compared to Tesla's 3000. This is why it will last 30 years.
That's 800 000 total kwh vs Tesla's 40 000. This is no a lead acid battery where you never charge over 50%.
These hydrogen batteries ... could replace the fuel tanks in hydrogen fuel cell cars ... charging could be as simple as plugging in a fully charged batter.
We have yet to find out how FAST these hydrogen batteries can be charged, and odds are they will be faster than Lithium batteries.
Very promising technology ... that's already better than the Tesla Powerwall.
Ford or Toyota need to contact those Aussies asap for the battery technology for their fuel cell vehicles, but also to get these storage units homes and businesses asap.
Just imaging a standard hydrogen battery pack ... that you can easily plug into a supercharging station, home charging station, various machinery, ... or your vehicle.
@@Kupacolypse 50% efficiency
Yeah i agree I does mean you will need more solar and or wind generators. But I would be happy with that.
The price is the main disadvantage of this product. It's not affordable.
It will go down once is sold internationally. From 2021 to 2023 there is a price drop of $4,100 and thereafter will be sold internationally and will be drop much more
You can use the the energy losses as a heat in your heating system through heat pump that make the system more efficient
It would be perfect if hte energy loss could be used in hot water system. we use hot water everyday.
Does the system deliver 40kwh output?
Thanks for your video, I am always happy to see new ideas for storing energy, but why I will use solar panels that produce electricity, to then produce hydrogen (need a lot of energy to produce) and then use it for a wall battery for electricity use, that is wast of energy, this system is good for hydrogen power cars only, hydrogen-powered cars must store hydrogen as fuel to produce electricity from a fuel cell, so this system is good for hydrogen home refuelling system not as wall battery for electricity use.
Question: a battery will empty out all charged sitting there idle without charge right? Hydrogen tank empty out all hydrogen in how many days, months, years, when not in use, nor charge?
Fuck that price tag. I’ll wait several years when it gets cheaper.
I am from Australia, not a single unit is there to be reviewed by a actual consumer. Hydrogen technology is very inefficient, water is expensive in Australia too.
I want a hydrogen fuel cell suv that can supply power to the whole house for at least 4+ days, and I can just easy hook it up and unhook it to go refill. Super for camping too:)
A battery discharge faster, and self drain faster when it get older right? Also, may take longer to recharge, which mean less storage per sunny day/s right. Hydrogen tank???
Hydrogen home storage is bunk. 1 Kg of hydrogen takes from 44-55 kW/ hrs of electricity to produce. So assuming the average home had a 5kW system, it would take you days to produce that kilogram assuming you have excess electricity. You would then be able to obtain about 60% of that back as electricity when you needed it. Much easier ( and reduces payback time for your solar panels) to sell that back into the grid. Another way of looking at it is that to produce 1 KG of hydrogen in about an hour you would need a solar array 10 times the size of a 5 kW household system, so your roof wouldn't be big enough to hold a system of that size. The storage system you mention is about $25 thousand US dollars and is not yet in production and available on Pre order. You could buy three Tesla Powerwalls TODAY that are much more efficient as a means of household energy storage receiving a great deal more energy back as usable energy . Hydrogen Might have a place in long range transport, or other large scale uses but that's about it. Capital energy producers might be able to make it relatively cheaply, but the average household would not be able to. Even the most optimistic forecasts suggest it will be 10 years or more before Hydrogen prices for green hydrogen fall to a competitive level with Steam reformed Hydrogen ( And they don't use steam reformed hydrogen at the moment for household energy due to its cost) That is not to mention Maintenance costs of the system. (How pure is your household water supply???)
Agreed ,spot on
1kg of hydrogen can be converted to 33.6kwh of electricity have a look at the Toyota Miria that travels 1000km on a 5.6l (kilo) tank of hydrogen. Hydrogen has the highest energy density around per kilo. A 5kw solar array can in theory produce 5kw per hour but in reality is is much less more like 2kw per hour. Assuming your not using power during the day because your at work you could expect to produce up 10-15kwh's. This would mean when you got home you could use this to power your home. But if you connect your Tesla which needs 22kwh to charge for the next day you will still not have enough to power you house. In reality you will need a much bigger array probably 20kw or more.
@@justindressler5992 1kg of hydrogen can be converted in 33.6kwh only in an imaginary world where the laws of thermodynamics doesn't apply.
When you convert one type of energy to another you always have losses. When you convert hydrogen in electricity you have at the moment an efficiency of 60% top meaning that from 1kg of hydrogen with a potential content of 33.6kwh of energy you get 20.16kwh (19.15 after a DC/AC converter if you want to use it for your home).
Same thing happens if you want use hydrogen as storage energy, this time is a bit better as it can be around 80% efficient so if you produce 15kwh a day you can produce 12kwh worth of hydrogen (357 grams of hydrogen ) that when converted back to electricity you get 7.2kwh.
So ,not counting the losses incurred when you store and release the hydrogen from the metal hydride sponge canisters, with this rather expensive storage medium you basically lose 50% of the energy harvested from the sun.
The mirai example is not really appropriate, the 1000km record was achieved during an eco-run and they used 5.6kg of hydrogen that while would mean "only" 188kwh of energy used , to produce ,move and compress the hydrogen to 700bar ,1kg of hydrogen in the mirai tank requires 50-55kwh of energy meaning that a full fill up in 5 minutes takes between 280 to 308kwh of energy whereas a model 3 , already achieved 1000km in an eco-run on open road with 66kwh of energy from the battery ( 76-80kwh if you count the charging and transportation losses of the electricity from the plant to the battery).
So far I see people compare brand new stuffs, but not much after they get 5+ years.
How many solar panels would i need to run this beast?
How would that work left outside in cold weather climates? Water would freeze. And what about the solar panels they only Viable about 20 years. Once you factor in changing the fuel cell and the panels. It costs more than grid power.
Because of the round trip effciency of 50% is it 20 KWh from 40KWh....Or you need to dump 80 KWh of solar into it to charge to full 40 KWh? hmmm
Anybody buy this yet. I'm trying to get one but waiting list applies
How much drinking water does it produce in liter?
Thats a very good questions, and I wish I had an answer!
If only I could use these modules in my EV.......... Charge them in daytime, come home and exchange 1 or 2 and be ready for the next trip....
Storing energy for back up anomaly’s is one thing, so that production costs of that fuel and efficiency are more insignificant. It’s the daily advantage of practical use vs electrical solar in raw cost per KWh. Asset up front costs divided back into asset life period and average KWh costs is an important but separate cost. It is likely that both systems will be in place for 10 years as a data point and 15 to 20 is more likely the practical life for data point purposes. It’s like an old car... thing corrode, seals decay. Parts on gen #1 of these after ten years could. be wishful thinking.
Practically, if it’s not almost all pure profit after seven to ten years, it’s probably a joke monetarily to still call it an “investment”. If it’s your final home and want to save money in your retirement years, the asset life story changes the data points. However, You have to factor in risk of needing bulk replacement after year ten. It would be a sliding scale from a risk perspective. You could “budget fund” that with $1000 added to a budget year 11 and increasing the amount by 15% more per year replaces the system by year 20. Costs are unknown but you have to understand it’s not free lollipops and cotton candy forever.
Most of all, hype played into your vulnerability of wanting to do right should not fog the truth in numbers. With that said... Would love this hydrogen system play out. We will never learn without lots of data points. Just understand it’s a new chapter in the book.
That moustache needs a tuxedo and a top hat
Wouldn't it be cool if we had solid-state hydrogen generators made in Arizona on the side of the house that weighs 70% less, can not explode, does not have a battery or capacitor, and can absorb CO2 for half the price of liquid or compressed hydrogen generators?
Where
The win too is the cycle rate. 20k compared to teslas 3k is dope. Shut up and take my money!
It's all about cost.. and output...
Solar cells are in a pricerange where you just adjust the number of cells..
But at 26.000 $ it will take a long for break-even...
It's also about the supply chain used in manufacturing these systems. I would rather have a hydrogen storage system than a lithium battery system that uses rare earth minerals mined in 3rd world countries. The greenest option would be hydrogen imo
@@ArchaicSeeker currently to split water into hydrogen and oxygen you still need rare (expensive minerals) for efficiency.
I don't think hydrogen is a stand-alone energy storage. Rather the excess-carrier.
Batteries are way more effective from day to day. On site. On demand. On/off. Plug and play. Close to a 1:1 in/out ratio.
Hydrogen needs a much larger logistical solution. And need way more input than you get out.
And devices using power still need tons and tons of rare earth elements.
Not throwing 50% of my solar production away. For prolonged needs where solar recharging during power out is important, this is a big disadvantage. Still holding out for Tesla power wall 3
Tesla is not an independent system so you cannot use the powerwall off-grid. Furthermore, the powerwall 2 is so tightly controlled that here in California, you cannot charge the battery from the grid... only solar. (Unless a "storm watch" is active, which is never.) Any net metering customer should not get a powerwall unless it is free via referrals...
@@CtrlAltDL337 My use would be temporary grid loss. Don’t need to charge battery from grid, though charging from a small generator would be great. I need for power down situations d/t weather.
@@ystebadvonschlegel3295 You are golden then. Any power is better than no power. I believe for grid loss, any system will do because in an emergency (ie. earthquake, fire, wind etc.), no one cares where the power comes from as long as you have it!
@@CtrlAltDL337 how would the "safer and more efficient" (sarcasm) hydrogen battery be better?
@@SebastianLopez-nh1rr Ask the manufacturer, not a stranger on the internet.
Right to the point: the exothermic reaction of combusting the element of hydrogen in gaseous form to produce work against any "neighboring molecules" is THE MOST EFFICIENT form of energy transfer when conducted under ideal conditions (the most "bang for the buck"). Hydrogen is the smallest and most abundant element in the universe, and remains the most efficient means of lift for dirigibles and other airships as a gas...and may very well have already been a more widespread means today if it hadn't gotten such a bad rap due to that "pesky" Hindenburg incident (just a distasteful joke, of course...it was a horrible tragedy for the victims and their families...). That being said, the arguments in the comments here seem to be mostly about the inefficiency of PRODUCING or CONVERTING hydrogen BACK into its elemental form to be stored for later combustion, which is where most of the theoretical efficiency is lost (and, fair enough, indeed!).
I have been contemplating the energy efficiency problem for some time now, and I think it is worth ALL of our collective time and attention to consider it seriously (despite differing views). I also think that no matter what energy producing/storage system is talked about, it is important to always keep the "big picture" in mind (which could mean different things to different folks, and, perhaps, for good reason I'm sure--none of which I will comment on for this purpose, however), and that is to look at every component of the process to determine what the maximum efficiency would/could be like at every step (i.e. where's the benefit?).
My conclusion on the subject of hydrogen as a fuel source is simply this: "We" need to "collectively" do a better job of PRODUCING hydrogen as a fuel source for ubiquitous use and storage via a much simpler process (or processes). My "two-cents" would be to focus on SURFACE AREA of the anode/cathode arrangement for electrolysis, for one (as some emerging technologies are showing promise to do (e.g. PEM electrolyzers), OR to devise some other way of obtaining/producing it. As of today, it is not a very stewardly use of electricity that is produced from some other source (even renewable), which is stored in degradable vessels, conveyed via degradable materials, used second-hand to convert (pure?) H20 into hydrogen/oxygen, and, yet again, be stored/used in degradable vessels/materials to eventually be converted BACK into electricity for work to be done for future, end-use applications. The electricity produced and stored in the FIRST part of the process is far more sustainable. In my opinion, large-scale use of the subject H2 process as it stands TODAY is BACKWARD-THINKING regarding "sustainable energy" as we do not yet have an efficient means of extracting and storing hydrogen's full potential energy for future use.
@user-ky7iz6up1v It does not appear that you received the “take-aways” from my (albeit lengthy) comment a year ago now, but the most important part is that it makes no sense to generate a less efficient fuel source using electricity that’s generated from a more efficient fuel source already (like solar). You’re wasting electricity to produce less….electricity. And what makes you think “big oil” has anything to do with it? It’s a non-starter sales pitch..z
How much would it cost $
what's wrong with your lightning?
Comparing to storing electricity in a battery and retrieve directly, this method gone through electrolysis-hydrogen storage in metal hydrides-hydrogen fuel cell......Where are the benefits?
It doesn't require lithium. A metal that creates a lot of pollution when mined. It is also mined in countries with extremely poor human rights records, such as Afghanistan, China, and North Korea.
@@Nilsy1975 Australia is one of the main suppliers of lithium. Do you think fossil fuels don't create pollution?? Look up Port Stanvac refinery. They tried for years to not have to clean up the site. Why? The cost. Every other refinery will be just the same. I note you can't find one other benefit for this system.
@@colconn57 Well, I stand corrected about the source of lithium. It's one of those"facts" you often hear that sounds plausible and I should have checked.
I never mentioned fossil fuels and accept Anthropogenic Climate Change as a scientific fact. As for pollution caused by fossil fuels, well, yes they do cause pollution in many ways.
918ausi asked what are the benefits [of using hydrogen]?
My reply was it didn't require lithium.
I think hydrogen is a potential replacement for fossil fuels, especially in airplanes, lorries, and ships, as lithium batteries have limitations. I am all for transitioning to renewable energy sources.
I would say there is less yield that 50 %. I would say 40 max max %.
Not bad in efficiency it can go up but what is the technology did't discussed.

why people always pay too much attention to efficiency?
Taking into account how cheap solar panels has become vs trying to store that power.
To store 2 hours of a PV output every day using batteries.. the capital need it is 10 times more on batteries than on solar panels.. This is for only 2 hours!!
This mean that doubling your solar panel installation cost nothing vs your storage.
Seems like they are in hibernation stage

Is it just me or flickering in this video just crazy :|
It has a much lower round-trip efficiency so a bigger battery doesn’t mean more electric
seems viable to me.
This is perfect for people who drive hydrogen fuel cell vehicles
Well if you can take the hydrogen and pressurize it and fill it in your car
ka-boom
The system can hold around 2kg of hydrogen that would be enough for a small refill, after you pressurize it to more than 700bar. That would be probably noisy ,slow and use around 3-4kWh of electricity.

@@dalerolph ok water is the most abundant source on earth. Fossil fuels is currently a trillion upon trillion dollar industry. Its a fact that such fuel released such chemicals such as carbon monoxide which is deadly to humans as well as life. There something called DESALINATION and something called ELECTROLYSIS.

Solar and wind is currently not sufficient to meet our energy needs. If we had the incentive we could create reservoirs across the world using it for drinking water, agriculture, cattle, construction and ENERGY.

@@justindressler5992 At what point did I state that Lithium ion batteries was a good idea? You have leaped to an conclusion.
*The devil is the details* , competitive vs battery? hardly :
-The warranty of 10 years and 30 years lifespan is on the hydride *only* , basically the "sponge" inside the tanks , the least expensive part , you do however need to consider parts like :
the fuel cell (*very* expensive) has a lifespan of 30.000h, that's 3.5 years they say on "normal" usage it should last around 10 years but then it means basically turning it completely off for 2/3 of the day not producing H2 or electricity (basically an expensive backup generator) , then you have the water filtration system , I can't tell the lifespan but as for any water filtration systems, it does require frequent, periodic maintenance , also the "small" 5kWh battery is tasked to be discharged to 1C (5kW) than the typical 0.5 discharge rate of battery storage systems that will result in a shorter lifespan (stated as 10-15 years vs around 20-25 of battery storage systems)
in fact on their website they state :
" *An annual maintenance will likely be recommended by a qualified technician to undertake the general inspection and replacement of any consumables like filters, coolant levels and electrolyser fluids etc. which is dependent on environmental factors and usage patterns* " AKA : you will need our technicians to inspect and replace stuff every year on you expenses or you'll lose the warranty and get the filtration stuffed up and the fuel cell seized (degraded by element poisoning ) within one year .
I can't understand of LAVO can claim their system roundtrip efficiency is "way above 50%" when they use Nestack fuel cell and their best efficiency conversion of H2 to electricity is 56% , so if you take a 20% loss of the electrolyzer you have in the best case scenario a round trip efficiency of 45% and this without taking account of the AC/DC inverter , battery ,hydride sponge and the water filtration system losses .
Now let's compare with battery systems :
1x LAVO : 26.900$ onboard energy 40kWh , max output 5kW , energy useable after DC/AC = *20kWh* (i'm generous), generate noise, maintenance required ,consumable parts , requires a good amount of space and it's heavy 560kg with the tanks included .
2x Powerwall : 24.000$ onboard energy 27kWh max peak power 14kW , energy useable after the DC/AC inverter= *25.6kWh* , virtually silent, no maintenance required ,take less space , and weight less than half of a LAVO system .
You don't understand, because you don't believe in the tech and have your own skewed view of the details and numbers.
This is an Australian company, not American but by the way you have been bitching about their claims, you don't see any difference. And there is a difference.
The devil is messing with the details What ever those details actually are, they are all trumped by the fact that this is a truly GREEN battery, that can store 40 kwh and has 20 000 cycles ... whereas Tesla has a chemical battery, that can store 13.6 Kwh and has 3 000 cycles.
This is the first generation of hydrogen battery technology which apart from its size, immediately is competitive with lithium batteries. You can't get any greener than hydrogen gas, and there's no blasting of methane with steam to produce it.
Hydrogen batteries are the future. The storage capacity, fuel cell & production tech will all improve, get cheaper, more reliable & efficient ... and .... smaller.
These hydrogen batteries will replace the high pressure tanks in fuel cell vehicles, and you simply have to recharge the battery at a supercharger, station or at home with you Lavo system ... or carry fully charge extra in the boot. it is obvious, that to supercharge these Hydrogen batteries will be a whole lot faster than the lithium battery. Again. The tech is only going to get better as Hydrogen or similar GREEN batteries is the future.
Yeah. The devil is in the details. That you conveniently did not bring up because you wanted to bitch about hydrogen gas technology.
Efficiency is irrelevant if it's only charging off solar. My concern is the extra residential water use: plenty of places in the world are water scarce. I mean, they're starting with Australia so I guess we'll find out the impact in one such place before it goes international. But the key question is really: How much water is used to fully charge it?
water is not an issue, because you can generate a lot of hydrogen from little water.
So the system works by filling a small reservoir and then converting it, rather than extracting hydrogen as water flows *through*? That's good.
no not really;
on the input side I agree, I have large solar system so free marginal cost electicity,
but there is a big difference between $AUD30,000 for either 40 kWh or 20 kWh system,
especially when not disclosed openly and up front

According to global estimates by the U.S. Geological Survey on 2016 A.D., there is enough Lithium in the world - 13.5 million metric tons of it - to last us over 350 years in batteries, that is after the year 2366 A.D.
@@QANGOR that may so but I have not seen any data yet on how much CO2 is generated in mining it, How much C02 is generated in making the metals and structure of the batteries , and How much C02 is generated in trying to Recycle it. Hydrogen has a much smaller C02 footprint and As I said the energy extraction causes only water to be produced. Also one cannot make an economy around lithium alone. With Hydrogen as your main fuel one can have an economy based on Hydrogen.
@@TG-lp9vi i don't know the exact figure but extracting lithium is a very lenghty dirty process. The carbon footprint of Lithium for sure is high. Lithium also does NOT have the energy density that Hydrogen does. (at least not yet)
Lithium batteries in a Powerwall lasts much longer then 12 to 15 years. More like 30 years. For cars a bit shorter if you wish to have the same range as when the car was new.
Yeah, these guys have clearly never dealt with hard/dirty water.
Has water purification system in it too
This is not better in anyway to the 5 year old proven Tesla PW solution

Hydrogen burns wonderfully and oxygen may have other uses. What LAVO should think about is providing line outputs for each.
The hydrogen could be used for gas appliances (stove, heaters, etc.).
Oh dear, you only get 50% of the energy you inject! What a tragedy! Much better engines that follow the carnot cycle, that after more than a century of development do not reach or will reach a similar ratio. How much a diesel? 35-40% of the contained energy you paid for? Good video. Thks.
the whole idea is "we have to stop burning ff"
Scam, confirmed.
I too enjoy keeping bombs in my house.
I'm turning off this video just because of your mustache
Dube you better stay the hell away from that thing or soon your new nickname will be Beirut...💀💀💀
