What are the Challenges in Catalytic Hydrogen Generation?
Despite the advancements, several challenges remain in catalytic hydrogen generation:
Cost of Catalysts: Precious metals like platinum and iridium, which are highly effective, are also very expensive. Developing cost-effective and equally efficient alternatives is a major challenge. Durability and Stability: Catalysts can degrade over time due to high temperatures or harsh chemical environments, leading to reduced efficiency and the need for frequent replacement. Energy Efficiency: Some methods, like electrolysis, require significant amounts of energy, which can make hydrogen generation less sustainable if the energy is not sourced from renewables. Scale-up Issues: Laboratory successes often face scalability challenges when transitioning to industrial-scale production.
