Volkswagen Crafter electric van without range extender


THE FLEET OPERATORS DILEMMA - In 2021 the transport sector still depends almost entirely on fossil fuels, and is responsible for over 20% of the world’s CO2 emissions. Yet, one kg of hydrogen replaces 10 liters of diesel/petrol giving a driving range of up to 130 km.







A Hydrogen Battery is a fuel cell and hydrogen storage system that works in combination to form an energy pack, to equal a conventional battery. A Universal battery cartridge is designed to service any suitable electrically propelled vehicle, including buses, cars, vans, and long haul trucks, based on standard sizes of cartridges or packs. This is an option for vehicle OEMs, by way of fuel-future-proofing new EVs.


But the most important thing about a 'Hydrogen Battery' is that it is the beating heart of the SmartNet™ service stations. These magnificent cartridges store hydrogen and release it as electricity on demand for load-leveling national grids. It is almost incidental, that they make convenient (bolt on) range extenders for commercial vans and trucks.


The system provides massive energy storage potential for mismatched solar and wind generated (renewable) electricity in remote regions, for use in cities in other regions.


Say goodbye V2G, that robs motorists of energy, from their onboard battery packs. Although, until we have SmartNet,™ Vehicle-To-Grid, is one way of tackling the problem. At least the utilities have cottoned to that.




When manufactured in large numbers, a Universal cartridge will be significantly cheaper to produce than hundreds of different systems from dozens of OESs.




Hydrogen cartridges can contain gas at 700 bar, or liquid hydrogen in combination with a matched bank of fuel cells. The gas version will give 270+ miles per exchange in a typical family car, like the Toyota Mirai. It is anticipated that a liquid hydrogen version will have a significantly longer range of around 470 miles.


The safety cartridges are stackable for vans and trucks, offering 1,000 mile ranges on long haul vehicles using the high-pressure gas example and 1,750 mile ranges on liquid hydrogen, by way of fully developed examples. But, please note that these are only estimates until the concept is proven.






ONE SIZE FITS ALL - Well, very nearly. As part of this project we need to define the physical dimensions of the pack, so that it can be stacked to provide electrical energy for all trucks, and around 90% of cars that at present use lithium battery packs.




Cartridge exchanges take just a couple of minutes at dedicated rapid, smart service stations. Spent cartridges are refilled automatically, cyclically, with hydrogen and stored until requested by other vehicles passing through the station forecourt.


The proposed system is compatible with Pay As You Drive (PAYD) technology. This makes the purchase price of an EV much lower than other systems. You pay for energy and cartridge depreciation at every fill up, regardless of using hydrogen fuel cell packs or lithium battery packs, because they are compatible with this versatile system.




Batteries and Fuel Cells do not last forever and sometimes get damaged or become faulty. With millions of vehicles using electrical storage for their increasingly powerful motors, there will be hundreds of thousands of EV breakdowns every year.


Vehicles using the standardized 'Universal' cartridge system, can be serviced by the roadside, by any equipped recovery service, such as the AA, Green Flag, and RAC - and be on their way again in minutes.


Vehicles with bolt in battery packs or fuel cells, will more than likely need to go to a dealer for repairs and servicing.






FIAT DUCATO EV CONVERSION - This battery electric has a range of 112 miles. With a hydrogen battery as a range extender, refuelling time can be cut from 4 hours plug in charging, to just a couple of minutes. In addition, the range will be roughly trebled.









PLUG IN CHARGERS - For a while plugging in to charge your EVs might be feasible, but as electrics become more popular, they will soak up energy from the grids that supply homes, offices and factories, putting an enormous strain on the present infrastructure. For some reason policy makers and vehicle OEMs don't appear to be able to see that far into the future. Our crystal ball makes that much plain, without any eye drops.
