Production and pricing
Only raw materials, energy and transportation costs are taken into account in the pricing. Amortizations of investments, business operation costs, and profit to be realized have not been taken into consideration.
The costing is based on 0.5 KG of H2: this means that this price is equal to 1 KG of H2 for the consumer (Reaction = 4H from NaBH4 and 4H from UPW = 8H).
It has already been shown that the price of the energy greatly influences the final price.
The costing is therefore based on 2 situations:
- Purchased supplementary energy.
- Supplementary sustainable energy acquired from owned installations.
In addition, these have been compared with the process indicated by Dr. Wu in patent WO 2004/101431 A2 which could result in further energy conservation.
Furthermore, the cost of the hydrogen released from the reaction and which was stored in the NaBH4 was attributed completely to the outgoing energy (the external synthesis and the fuel cell) and the cost of the hydrogen which is released from the UPW was attributed to the internal process (internal synthesis and energy synthesis).
The primary reasons for this are:
- The cost of NaBH4 = X and the cost of UPW = negligible or 0.
- The cost of the external synthesis is halved in the reaction when used by the
consumer (0.5 KG from NaBH4 and 0.5 KG from UPW = 1 KG).
The overall calculation is in line with the sum of the parts
Production and pricing including optimization Wu/Arhus.
Production and pricing excluding optimization Wu/Arhus.
Cost based on the Gibbs energies with the application of Wu’s process.
In his presentations Dr. Y. Wu has claimed to require 62.5 MJ for 0.5 kg of H2 in NaBH4
