Abstract
- Hydrogen is a clean energy in the world and by-product hydrogen is an important part of global hydrogen production. The yield of by-product hydrogen accounts for 18% of hydrogen production globally. To analyze the current stage and calculate CO 2 emissions reduction of by-product hydrogen, sources, purification technology, utilization models, comparison of by-product hydrogen and other hydrogen resources, reduction of CO 2 emissions, prospects of industrial by-product hydrogen were analyzed from the respective of industrial utilization. The resources of by-product hydrogen will get expanded further. It can facilitate the utilization of industrial by-product hydrogen to establish industrial zone with the factories producing by-product hydrogen and the downstream factories utilizing by-product hydrogen under the current technology conditions. By analyzing the relevant data, it is calculated that the utilization of industrial by-product hydrogen can reduce CO 2 emissions by 6.11x105 t per year in 2022. With the development of hydrogen purification technology, by-product hydrogen can provide an efficient and economical way to reduce CO 2 emissions for global warming migration before the completion of green hydrogen substitution for other hydrogen. [Display omitted] • CO 2 emissions reduction can reach 6.11x105 t/a through the utilization of by-product hydrogen in 2022. • Hydrogen purification technology plays a significant role in the utilization of industrial by-product hydrogen. • The resources of industrial by-product hydrogen will get expanded in the future.
