Platinum, Green hydrogen, Hydrogen fuel cells, Renewable energy, Supply and Demand, ElectrolyzersAbstract
Platinum is an important element needed for producing “Green” hydrogen, hydrogen produced from renewable energy sources. This paper is a comprehensive overview of platinum, describing various factors from the geology of platinum to its use in modern technology. Platinum is a highly efficient catalyst used in electrolyzers to generate hydrogen from water and to build hydrogen fuel cells. Published theories describing the unique physics and chemistry of platinum in relation to interactions with hydrogen will be explored. The key advantages and disadvantages of platinum compared to alternative materials in the green hydrogen and fuel cell industry will be discussed. The current state of geological occurrences and rarity of platinum resulting in supply shortfalls and geopolitical challenges will be described.
