Cost effective and versatile hydrogen fuel production technology, ready for the energy transition and competitive to fossil fuels.
If you could place at every existing fuel station, a box that generates hydrogen and electricity with or without grid power, what would that do for the hydrogen economy and energy transition?
Hydrogen fuel cell mobility is stacked-up to be a serious competitor to battery electric mobility. Data indicates that the consumers would change over to FCEV with rapid acceptance, unlike the resistance to battery EV's.
The only obvious hurdles are fuel infrastructure and price of hydrogen. With 97% of the worlds supply being grey and blue hydrogen, the high pump price must reflect a costly transportation and supply chain. On top of this, green hydrogen is 3 times the price to produce.
Substitute the costly gas supply chain with large scale, on-site hydrogen production that compliments current power grids. An on-site 'Box' that can even generate hydrogen without reliance on grid power. A solution that also delivers an attractive, immediate return on investment by supplying power to the grid while the demand for mobility supply is low. A small scale renewable energy farm at every fuel station, waiting for the increase in FCEV mobility to consume the hydrogen.
The H2IL G.E.E. technology provides such a solution with an equipment manufacturing price one quarter that of conventional PEM electrolyzers. A transition to clean energy and fuel with a supply chain for trucks, busses, trains and cars throughout cities, suburbs and even outback locations.
Conventional electrolyzers are very power intensive. This fact prevents them from generating enough hydrogen where the grid is unable to support hugh power demands.
Transporting hydrogen to these remote locations would also be commercially non-viable due to the gas volume to density.
However, transporting sea water, or salt powder to mix with rain water, is a viable option. A single truck load of galvanic energy rods held in storage would supply several years worth of hydrogen.
H2 production capacity is fully scalable by size.
Being a combination of electrolyzer and battery technology within the same electrochemical cell, the scale-ability of both technologies apply. If an electrolyzer is doubled in size it produces twice the output. But if a battery is double in size, the capacity increases by a factor of 3 to 7.
Following this principles, the G.E.E. has proven in verification tests, to increase output and performance on a logarithmic scale with cell size increase.
For example a 1 cubic meter cell would generate 20 to 40 kg of hydrogen per day while a 24 cubic meter (3mx4m footprint) would generate 690 Kg per day. The 24 cubic cell would consume just 19 kWh of electricity.
Transported high volumes of hydrogen require large storage tanks. Hydrogen vessels and pipelines are very different in structure than naturalgas equipment. Hydrogen seeps through most metal substrates.
Unlike instant conversion to electricity, a transportation application for the H2IL technology will require gas holding tanks, but much smaller. With higher volume of hydrogen being produced each hour, the storage time and capacity would be much less.
When the tanks are fill, the system can switch over to local grid power generation mode. Supporting the grid and providing instant, ongoing revenue while the FCEV market gains momentum. See Microgrids.
The technology also presents the option of charging battery EV's at the same station. Converting some of the produced H2 back to electricity via fuel cells.
On-site H2 production eliminating complex and expensive storage and transportation or pipelines.
Exceptionally low power draw enables direct feed from existing grid without upgrade.
Exceptionally high efficiency enables self-sustaining installations where a small portion the output H2 feeds back through fuel cells to self-power the G.E.E, compressors and equipment.
Solution to the chicken/egg conundrum by delivering a very profitable revenue from grid support power generation (similar to wind turbines) while the FCEV market is gaining popularity.
Cost competitive to blue and grey hydrogen as well as fossil fuels.
Unique infrastructure that fits in with limited fuel station land area. Most the equipment including G.E.E. cells can be positioned below ground level.
Here illustrated is an example of below ground H2 generators along side the fueling outlets. This is achievable for the following reasons:
Hydrogen travels upwards, unlike all other gasses and fuels that would collect in a below ground confinement. Unexpected leaks would disperse through rooftop vents, away from any ignition triggers.
The G.E.E. system does not radiate much heat. Conventional electrolyzers convert 40% of the energy into heat that needs to be radiated in an open air environment.
Above ground installations would be a viable option where land area is not an issue. This simply illustratres the scope of possibilities and solutions this technology offers.
Installations are not limited to current fuel stations. The technology expands fuel infrastructure to more localised fuel outlets including parking lots, privately owned microgrid power stations and beyond.
H2IL is taking expressions of interest in worldwide technology acquisition including patents and hidden IP.
