The article discusses the imperative need for energy efficiency in green hydrogen production to address the projected surge in demand by 2050. Danfoss emphasizes the critical role of green hydrogen in transitioning away from fossil fuels while highlighting the need for a nuanced approach to its production and utilization. The MENA region's potential in spearheading the green hydrogen revolution is underscored, particularly in decarbonizing hard-to-abate sectors like heavy industry and long-distance transport. Efficiency measures such as optimizing converters for electrolyzers are noted for their impact on overall production efficiency. The article emphasizes the importance of prioritizing green hydrogen for sectors difficult to decarbonize and the necessity of strategic allocation given its limited resource status. Moreover, the article mentions the global electrolysis capacity targets set for 2030 to meet the Paris Agreement goals. Despite the promising growth prospects for green hydrogen production, challenges like cost and slow progress are hindering deployment. The importance of recovering excess heat from electrolysis is highlighted as a significant energy efficiency measure. In conclusion, the Danfoss Impact paper advocates for a balanced approach to green hydrogen production, focusing on efficiency, affordability, and strategic allocation. The key takeaways stress the need for efficient production processes to minimize energy loss and demand, propel green hydrogen into hard-to-abate sectors, and drive the green transition forward.
