Do you think it will become priced for residential usage?
What of it's dependency on natural gas? And it will emit CO2...
Bio-gas and Synthesis gas can be used as feedstock... is this technology only going to meaningful to power companies? Who will probably utilize the technology to replace existing power stations and sell that energy.
They state right in the video that it emits 'a small amount of CC2.' The way they describe the chemical process of CH4+ H2O -> COH4, COH4 + 2 02 -> 3 H2O + CO2, every atom of carbon from the 'converted fuel' becomes the core of a CO2 molecule, so it's producing as much CO2 per mole of natural gas as combustion, it just needs to use less natural gas to produce a set amount of current than combustion, since the electrons are produced directly, rather than releasing the energy from the natural gas entirely as head, using that heat to create steam (with losses due to the second law of thermodynamics) then using that steam to run a turbine to produce electricity (losing more to the Second law).
I wonder how high the 'high temperature fuel cell' needs to be at to start the reaction, If the temperatures are feasable in a home environment, then I could see this being phased in slowly.
I also wonder if it could also run on straight hydrogen. I know, I know, Hydrogen is not an energy source, it is an energy currency, it takes more energy to produce hydrogen gas than you get from burning it or using it in a fuel cell. But if this fuel cell could work with straight hydrogen, then steam would be the only thing outgassing from it, no more CO2 from the power cell.
What we REALLY need is a cost-effective way to 'crack' water for the hydrogen, If the gear could be made to fit into a small car trailer, and be powered by solar panels on the trailer and possibly the car's roof, no more fill-ups at the pump. Granted, the solar powered water cracking refill of the hydrogen tank is likely to only be feasible in areas like the American Southwest, but it's a start.
Here, the electrolyte is a polymer ion exchange membrane that is very good at conducting protons often combined with an expensive platinum catalyst. These fuel cells are a good option for automotive and portable applications as they are best suited for fast start up and shut down situations.
Phosphoric Acid Fuel Cells (PAFC):
In this fuel cell, concentrated phosphoric acid is used as the electrolyte. The design and power outputs make them suitable for buses and large stationary applications.
Alkaline Fuel Cells (AFC):
The electrolyte is essentially a potassium hydroxide solution. These fuel cells are often used for expensive mission critical applications such as the USA space program.
Molten Carbonate Fuel Cells (MCFC):
These highly specialised fuel cells use a combination of high temperature alkali carbonates (sodium or potassium) as an electrolyte and can use a wide range of fuel types. MCFC are best suited to large stationary power applications.
Solid Oxide Fuel Cells (SOFC):
With SOFCs, the electrolyte is a solid non-porous ceramic based metal oxide often Yttria doped Zirconia material. Because SOFCs operate at high temperature, a wide range of fuels can be used with out having to specially pre-treat the fuel. The Bloom Box process... and your right!
A Solar powered system to split the Hydrogen and Oxygen... then use the Hydrogen would be optimum.
I've been following been this because two of the companies in our network have feedstock solutions based off Bio-Gas and Synthesis Gas. Diversified Energy Corporation has a gasification process (waste to energy)... OmniGas that creates and Synthesis Gas from petroleum coke, bio-mass and other carbon based waste.
And a Modular Gas to Liquid process from GasTechno that converts stranded, sour or otherwise gas (methane) to contaminated to enter a pipeline and typically flared off... into methanol... an exportable product.
