The global shift towards a clean energy future is gaining momentum to address the urgent need for decarbonization. Clean energy sources, including solar, wind, water, geothermal, and hydrogen, offer environmentally friendly alternatives to traditional fossil fuels, reducing greenhouse gas emissions and promoting a healthier planet. With significant investments in cleantech technologies, the clean energy industry is expanding rapidly, with a focus on enhancing sustainability. Hydrogen, as a clean fuel, stands out for its potential to revolutionize energy production. When produced using renewable energy sources, green hydrogen can play a vital role in decarbonizing sectors like transportation and power generation. Despite its advantages, challenges such as mass production, transportation, and cost efficiency need to be addressed for widespread adoption. The production of hydrogen fuel involves various methods, including thermal processes, electrolytic processes, solar-driven processes, and biological processes. Each method offers unique benefits and contributes to the versatility of hydrogen as an energy carrier. Innovative solutions, such as alternative catalysts to platinum in the electrolysis process, are being explored to improve efficiency and reduce costs. Platinum, a rare metal mined predominantly in South Africa, plays a crucial role in clean energy technologies. Its use as a catalyst in hydrogen production and applications in electronic components and catalytic converters underline its importance in reducing emissions and driving the global energy transition. As efforts continue to unlock the potential of hydrogen as a clean energy source, the role of platinum and the development of sustainable production methods will be key in realizing a greener future.
