We were making Hydrogen over 40 years ago with two Muffler Pipes one inside the other with little Clearance and plastic spacers, 12v Battery connected to each Pipe, a Bucket of tap Water with a upside-down Plate placed atop the bucket with a tiny air fitting in the centre, just another Hobby Project that actually worked.
Back to the Future: Worldwide there are several Hydrogen Manufacturing & Storage methods being rapidly developed, the Best System is what is dubbed as Green Hydrogen, meaning the Hydrogen is Generated & Stored within the same System, without the need to Deliver Grey Hydrogen compressed in Cylinders.
--- GREY Hydrogen ---
What is Grey Hydrogen ?
The Name Grey Hydrogen is given because the Hydrogen Manufactured, and then Delivered to the likes of a Service Station or storage Depot where the Hydrogen is then either Consumed or Delivered to the End user, like a Vehicle Charge Station or Converted into Heat for Consumption.
Grey Hydrogen simply incurs additional Costs to Deliver the Hydrogen to a site, where it will be Dispatched to the end user, in other words the Hydrogen being delivered, uses a vehicle & additional Labour. So our academics coin the phrase as Grey Hydrogen to be able classify the underlying costs incurred with the delivery of the Hydrogen.
--- GREEN Hydrogen ---
What is Green Hydrogen ?
Green Hydrogen is Hydrogen Manufactured & Dispatched to the End User at the Same Location as it is manufactured.
The best way to Manufacture Hydrogen is by utilising what would normally be Unused or Wasted Energy for any Generation source, like Solar, Wind, Aqua and Biogas being the most common forms of Energy that could be Harvested & Not Wasted.
Vehicles Filled from this Hydrogen EV Charge Station Manufacture the Hydrogen on site, so produces Green Hydrogen.
Also Retrofitted bolt-on Vehicle Hydrogen Systems manufacture Green Hydrogen, as they have an Electrolyser incorporated into the Vehicles system, where Water is topped-up into a tank and on-board Electrolyser Manufactures the Hydrogen, that in turn is used as a clean Fuel substitute to increase the Fuel efficiency of either Diesel or Petrol.
Recent University Tests confirm that using Hydrogen in a Vehicles Engine increases the Fuel efficiency of both Diesel & Petrol Engines between 35%~45%, as well as Cleaning out the Combustion chamber due to better combustion !
How is Hydrogen Stored ?
Commonly the Storing of Green Hydrogen is pressurised into material called Metal Hydrides (MHx) is the most Technologically relevant class of hydrogen storage materials, because the Hydrogen is only pressurised up-to 40 bar in special Canisters, and are used in a range of applications including;
- Electrochemical Cycling
- Thermal Storage.
- Heat Pumps.
- Neutron moderation.
Hydrogen Fuel Cell Technology:
There are many Hydrogen Fuel Cells of varying size being manufactured & available world wide, a lot are used in Hobby kits.
With a growing market in Vehicle Retrofitted Hydrogen Fuel Kits that only supply addition Hydrogen to substitute the existing Fuel a Vehicle engine uses saving form 35~45% Fuel efficiency.
--- Semi-Commercial Green Hydrogen ---
Australian Company GreenHy2 Pty Ltd is a publicly listed company on the ASX (HG2), is marketing & supporting the well established GKN Hydrogen Energy Storage Systems (HESS), that uses Metal Hydride as the Hydrogen Storage Medium that pressurise the Hydrogen up to 40bar.
GreenHy2 is partnered with GKN Hydrogen Technology in Australia, and the GKN Smallest unit is HY2MINI, where these can be scaled up to Commercial Grid Utility applications, by supplying a full suit of Commercial Hydrogen systems.
GKN is a commercial Manufacturer of Hydrogen Energy Storage & Hydrogen Heat Technology, currently GNK's smallest system is HY2MIMI module that is fully self contained system that Manufactures & Stores from 165kWh~420kWh of Energy within the 3mt (10') shipping container easily relocated to any location.
The HY2Mini is more suited for large Energy Consumers or semi-commercial applications like Crypto Data-mining, that we are currently looking to install and test this module in a 125kWh/p Solar Farm near Sydney.

--- LAVO in 2024 ---
WARNING: LAVO's Hydrogen system is starting to look like a Scam ! Especially after No answers to direct supply Questions, leaving us thinking there is some underlying Problem in there Hydrogen equipment manufacturing or storage medium &/or operational issues with the LAVO Hydrogen System !
Australian company LAVO website previously pouted in 2021 the release of a $26'000, 40kWh Residential Hydrogen Energy Storage System (HESS) that uses Metal Hydride as the Hydrogen Storage Medium, saying can be scaled up to Commercial applications, we now hear through the Hydrogen sector LAVO are Re-funding Customers who placed a deposit for there Hydrogen System.
LAVO's web-site previously showed 17 people on staff, NOW January 2024 there site is pretty well useless to directly Contact anyone of authority if looking to Purchase there Phantom Hydrogen System !
LAVO is NOW Only offering Lithium Phosphate Battery modules that DON"T have any Hydrogen components, these are just a LAVO branded Battery Casing with either 3.20kWh or 5.12kWh per module, all cloaked in subterfuge by offering "the LAVO Life system" or the "Energy-As-A-Service" (EAAS) bullshit, and supply an Inverter, Solar Panels & Electric Vehicle (EV) Charger, NO mention of Hydrogen at all !
This is LAVO EAAS Charges, if you are Foolish enough to Purchase there branded Lithium Battery System, good luck !
You are better-off Investing in the Outright Purchase of the System, and Disconnect from the State Grid, and Stop needing to Pay to Import Power back, as well as not needing to pay any Connection Fees.
Click on this image to see the Rates on offer;
Or Click Here to see LAVO Energy Rates on Diamond Energy site .
LAVO Yearly Charges Calculates to;
- LAVO Basic Green Plan Service Fee: @$3.25 x 365 days = $98.85 Month = $1'186.25 per Year or
- LAVO Premium Green Plan Service Fee: @$6.54 x 365 days = $198.92 Month = $2'387.10 per Year
- LAVO Green Plan Base Cap: 13.3kWh per Day, then you Pay 25c per kWh after the Cap, or
- LAVO Green Plan Premium Cap: 26.6kWh per Day, then you Pay 25c per kWh after the Cap.
- LAVO Metering & Data Charge of 60c Day = $219 Year.
- Plus you still have to Pay 25c per kWh if you Consume above the 13.3kWh or 26.6kWh Day LAVO Plan.
- Considering a 5.12kWh Lithium Phosphate Battery currently only Costs $3'500.00 each.
Until LAVO clarifies why there Hydrogen System is no-longer available, the below is just BS !
LAVO say there module produces hydrogen from tap water with an electrolyser, a process powered by solar panels or any other from of Hi-amp power. The Hydrogen is stores in patented Metal Hydride canisters, and is converted back into AC power on demand via a fuel cell .
The LAVO Module dimensions is said to be 168 x 124 x 40 cm and weighs approx. 200 kg, that's not bad considering 4x 10 kWh LiFePO4 Modules weigh 400kg – so the LAVO works out to be 200 kg lighter than four 10kWh LiFePO4 modules.
LAVO says a bathtub of water "could power the house for 2 weeks". So, anywhere from 300~400 litres. That's about a $1 worth of water. The company recommends using drinkable Town water, as hard or dirty water will result in the Filters and Reverse Osmosis membrane needing to be replaced more often, that's another ongoing cost to consider.
The round trip efficiency of the LAVO unit is said to be approximately 50%, due to energy being lost in the process of electrolysis and at the fuel cell conversion.
This YouTube video by "Just Have a Think" tells the story of this Technology, and is worth a listen, the good information starts at 5:30 seconds;
Until LAVO tables why there Hydrogen System is No-longer available, we recommend you avoid there "EAAS Lithium Battery Marketing spin", as they may not be around much longer !
--- Nickel Hydrogen Battery ---
Nickel Hydrogen (NiH2) Battery Technology was first used in Aerospace 30 years ago, and is still being used in the latest Aerospace projects like the International Space Station, Mars mission & powers the Mars Rover.
The NiH2 Batteries may be another solution for providing reliable Residential & Grid Scale Power, as they have a proven track record to Retain 86% or there Energy after 30'000 Cycles ENERVENUE is currently backing the Technology as the next step forward. Watch this Nickel Hydrogen Battery Video it explains it well;
--- VEHICLE Hydrogen Systems ---
This Australian company Hydrogen Fuel Systems is marketing Retrofitted Vehicle Hydrogen Fuel Systems, these appear to be able to increase the Vehicle Fuel Economy by up to from 34%~43%, they cost from $4'500~$5'500 per Kit depending on the Engine size.
This Vehicle Hydrogen System has been University Tested to provide an increase in Fuel Efficiency of between 32%~43%, for both Petrol & Diesel Engines.
Vehicle Hydrogen Kits only require three Fuel Cells that Manufacture & supply enough Hydrogen
There are fewer Commercial Hydrogen Fuel Cells, NUVERA is one of the leading Proton Exchange cells.
