Hydrogen Home Energy Storage

In this video we are going to look at two home hydrogen energy systems.
The two companies that are currently offering it are Lavo energy and Home Power Solutions (HPS).
Both the systems offer more energy capacity and longer life than Tesla Powerwall2

Personally, hydrogen - apart from the cost for smaller scale usage - has so many wonderful characteristics, including its energy density (~ 120 MJ/kg, 3 times gasoline), safety, environmental positives etc. As we are considering a move to solar/battery, I would love to utilise hydrogen but the up front cost is prohibitive. We're in Australia so Lavo would be our best option but at this point is too expensive, and for us, 5kW is not enough (at 240V = ~20A). As with your electric aviation channel, I'm always impressed by your contributions - many thanks from Sydney, Dave

Hps picea should go public and invest in automated factory and aim for mass production and cut costs.

I worked with a company 20 years ago that banked their existance on hydrogen energy. It didn't work out. That said there should be a simple solution to hydrogen production and storage. Still applaud the efforts.

To make things even, the lithium is warranted for 10 years but proper use lasts much longer. Just saying

Efficiency is everything! Batteries are about 90% efficient, but most hydrogen systems I've seen are about 25% efficient on a round trip basis . That said I think this system uses metal hydride to store the hydrogen and I've heard of a system using such technology achieve 50% efficiency. That's still not enough to compete.

Now 40kWh doesn't turn my head at all. I'm getting a 10kWh battery and that will be more than sufficient to store daytime solar to the night time, and even have surplus to cover a cloudy day for 9 months of the year.

My last challenge in my house is to capture the enormous surplus during the summertime and use it in winter. For that I need about 3MWH of storage. Now this product should be scalable. I wouldn't need additional electrolysers and fuelcells after all, but I do need the storage to be scaled upto 3MWH.

Now if the waste heat from the fuel cell could be scavenged and put into the house in the winter time, then the effective efficiency could be improved further. Maybe combining this product with a heatpump could improve efficiency further!

The big question for me is the efficiency?

If my solar panels make 10kwh, and we use that to put into hydrogen, how much will we get back?
I know with batteries that the answer is about 9.6kwh. So the loss isn't much at all.

If the seasonal storage version gives a reasonable round trip efficiency then it could be interesting.

Extremely Pricey !
though it lasts longer than LifePo4 batteries, the lifetime will not compensate for the cost

[davidwright]

I had dismissed hydrogen storage any costing on the large system. Your videos are excellent. Liked your solar cells video as well.

This technology is promising but really expensive for a regular household. The story will be the same as photogalvanic technology 15 years ago. We have to wait till chinese mass production going to broke down the price and it will be affortable for everyone.

[StonesXu]

Hello, in addition to being a supplier of lamps, but also a supplier of energy storage, we hope to have the opportunity to cooperate.

[jedics]

Hydrogen 'might' make sense as a way to store excesses of power in summer for winter use but not at this price, the diy space will probably figure out a way to do it at s 10th of the price before a business get the price down low enough.

[DreamingConcepts]

It would be so great to have flywheel energy storage for home.

I've seen some for microgrids, but haven't got any prices.

[ImNoExpert]

I have been following these solutions with wish to install them on my home. Question: you mention the cost of the LAVO unit but not of the PICEA. Have you any information on this?

[zumbatan]

I do envision the power of hydrogen use as fuel. Cost is the main obstacle. Hopefully, it will succeed.

[safdarkt]

Do it need a combustion engine to convert it in electrical energy?

[planetarytapestry]

Well Done. Thank you for the info. I try to stay ahead of the curve. It's people like you I rely on to help educate me. Thank you again.

[manoo]

This picea is a high pressure storage system and that is going to soak up a lot of power. A H2 fuel cell is only about 40% efficient, then you have losses through the inverter. All of which means you are going to be down to about 20% efficiency...thats terrible!!

[jamwar]

Did the series on superheroes end and if not can you do a video on ant man

[efeigbinobaro]

can you please do a video on black mantas suit from aqua man ? it looks practical to me and might be ST we can build with present technology. what do you think?

[trevorevans]

I love the idea but a price of $22, 000 scares me. With a power bill of $100 per month how long would it take to pay that off? But for the future, sounds great.

[missingpiece]

so a hydrogen truck comes by to refill it every year or so? I just don't think hydrogen makes any sense, after all these used EV batteries start getting connected to the grid for end of life use then we will have enough buffer to handle the times we don't have wind or sun. Hydrogen just seems like a lost cause because it just doesn't make sense and is not the direction everything is going. They use to make natural gas heat pumps with 5hp Briggs and Stratton engines too but guess what, it was a dumb idea that just introduced levels of complexity for no reason. Still like your video, and info.
