High-temperature Water Splitting
Using Solar Concentrators
Mirrors and Lenses are used to focus the sun light.
Electrolyzers
consist of an anode and a cathode separated by an electrolyte.
Types of Electrolyzers
Different electrolyzers function in slightly different ways.
The microbes split water much too slowly to be used for efficient,
commercial hydrogen production.
Conclusions
water electrolysis and small-scale natural gas reformers are suitable.Water
electrolysis is a proven technology that can be used in the early phases of
building a hydrogen infrastructure for the transport sector.
The photo -biological processes are at a very early stage of development with
so far low conversion efficiencies obtained.
Simulation Of Steam Methane
Reforming Using HYSYS
Although hydrogen is generally considered to be a clean fuel, it is important to
recognize that its production may result in environmental consequences.
The operation of the hydrogen plant itself produces very few emissions with the
exception of CO2
This in turn will lead to reduced resources, emissions, wastes, and energy
consumption. Future work will involve comparing this study with hydrogen
production via other routes such as biomass, wind, and photovoltaic's.
