Abstract
A new approach in the use of PGMs for the highly
catalytic activity in the production of hydrogen by water electrolysis,
is to reduce PGMs into nanometer size (nanophase), then integrate
them into electrodes. Water electrolysis is an environmental friendly
process of producing hydrogen.
This study was for the cognition of likely impacts to environment
with regard to the manufacturing process of the composite electrode.
The Life Cycle Inventory Assessment method and the carbon
footprint calculation in the preparation of the composite electrode
were essentially assisted by the Umberto for carbon footprint
software, which helped to build an inventory analysis and provided a
useful database of materials with respective carbon footprints. Direct
emissions were likely involved when heating, calcinating, drying
materials. Palliative recommendations were suggested in accordance
with the types of emissions identified.
