| Summary: | Theoretically, Methanol Steam Reforming (MSR) process to produce
hydrogen only requires endothermic heat with temperature lower than 100°C.
Meanwhile, waste heat in the temperature level of 100-150°C is disposed in huge
amount by various industrial sectors every year. If this abundant waste heat can be
recovered and stored into hydrogen energy through the MSR, a potential gain and
high-efficient energy system could be achieved. However, empirically, temperature
level ? 200°C is required for the MSR process to have high conversion from the
methanol to hydrogen. Therefore, Absorption Heat Pump (AHP) system is then
utilized to enhance the temperature level of the waste heat. Nevertheless, AHP
system certainly requires additional input energy. This research was to investigate
the feasibility of integrating the AHP system into MSR process to produce hydrogen.
Further consideration on hydrogen to electricity conversion using Fuel Cell (FC)
would also be provided. The feasibility study was conducted through the efficiency
calculations, either for energy or exergy terms, for several theoretical as well as
actual-approximation cases |
