WHAT IS A HYDROGEN BATTERY ?
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.
WHAT IS IN A HYDROGEN BATTERY ?
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.
HENRIETTA - thinks she may have something to chirp about. She thinks she may have cracked the 'chicken and egg' conundrum as far EV infrastructure is concerned.
It is almost incidental, that they make convenient (bolt on) range extenders for commercial vans and trucks, especially the new breed of robotrucks and taxis, that will require automated energy vending - since they have no human drivers in fully unmanned mode.
The system provides massive energy storage potential for mismatched solar and wind generated (renewable) electricity in remote regions, for use in smarter cities and rural locations.
Say goodbye to 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.
LOWER COST VERSATILITY
When manufactured in large numbers, a Universal cartridge will be significantly cheaper to produce than hundreds of different systems from dozens of OESs.
The 'Standard' casing and working parts of the 'Hydrogen Battery,' (including connectors, etc.), is suitable to contain lithium cells as a conventional battery pack, being interchangeable to overcome the energy mix dilemma that many Governments are looking to solve.
The device enhances the current electrification chain, as an attractive option for OEMs that have not yet decided to enter the FCEV market, or cannot decide if BEV or FCEV is where they should invest their money, but with the proposed 'Standard' cartridge casing, OEMs and OESs, do not have to bet on fuel cells or batteries (limiting their market appeal), because the energy storage medium may be either battery or hydrogen fuel cell, interchangeably - provided that their vehicle platform is compatible.
AUTOMATED, SELF DRIVING VEHICLES & ROBOTAXIS
The 'Universal' cartridge system is capable of supplying energy to vehicles that drive themselves, most likely for taxis and private cars where the owners have surrendered their keys (being elderly or not holding a driving licence). Such automated, unmanned vehicles, may refuel themselves unaided, at Smartnet™ service facilities. Cars with ordinary nozzles for hydrogen and plug-in battery charging require human assistance. Not so with Smart service stations. The cartridge system is thus future proofing for when automated vehicles become commonplace.
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 versatile 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 a standard 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. Again, PAYD is necessary for billing driverless vehicles.
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 at 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 be towed 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.
