中国石化新闻网讯 据能源世界网1月25日新德里报道，根据氢委员会发布的一份关于清洁氢生产和脱碳的报告，大规模的低碳氢供应在经济上和环境上都是可行的，如果采用最佳生产实践，将会带来显著的好处。 这份题为《氢脱碳途径》的报告指出，决策者必须把重点放在脱碳上，以确保氢充分发挥其潜力，成为全球能源转型的关键解决方案，为实现净零排放做出重大贡献。 液化空气公司董事长兼首席执行官、氢委员会联合主席伯努瓦·博捷（Benoit Potier）表示，如果氢能成为全球脱碳工业的解决方案并为能源转型做出贡献，那么只有通过减少碳排放并考虑到每个地区的特殊性，我们才能充分发挥其潜力。这将需要多种可再生能源和低碳途径的结合，并辅以有利的法规，以及进一步发展低碳氢技术。 该报告称，没有一种单一的氢生产途径可以实现低生命周期温室气体(GHG)排放，而是需要一种基于事实的方法，利用地区资源，包括不同的生产途径的组合。 这将有助于实现减排和降低成本，从而有助于能源系统脱碳和限制全球变暖。该报告探讨了三种假设的氢供应情况，以衡量大规模部署可再生能源和低碳氢的可行性和影响。通过可再生能源水电解生产的绿色氢达到最低排放，而天然气生产的蓝色氢具有高二氧化碳捕获率和存储能力，如果采用最佳技术和遵循最佳实践，也可以实现低排放。 在该报告中探讨的8种说明性途径中，分析表明，与传统化石燃料相比，温室气体减排可达60%-90%或更多。 该报告总结道，大规模供应低碳氢是完全可以实现的。在调查了两种假想的边界情况(仅绿色和仅蓝色情况)以评估脱碳氢供应的可行性和影响后，报告发现这两种情况都是可行的。 这两种氢不受世界可再生能源潜力或碳封存能力(CCS)的限制。氢能源委员会在2020年1月发布的数据显示，在可再生能源和低碳氢能源成本下降的推动下，到2030年，广泛的氢能源应用将具有竞争力。 郝芬 译自 能源世界网 原文如下： Clean hydrogen should be tapped to its full potential to reduce greenhouse gas emissions: Report Low carbon hydrogen supply at scale is economically and environmentally feasible and will have significant benefits if the best practices of production are used, according to a report published by the Hydrogen Council on clean hydrogen production and decarbonization. The report titled "Hydrogen Decarbonization Pathways" notes that decision-makers must put the focus on decarbonization to ensure hydrogen fulfills its potential as a key solution in the global energy transition, making a significant contribution to net-zero emissions. “If Hydrogen represents a global solution to decarbonize industry and to contribute to the energy transition, it’s only by reducing emissions along the chain and taking into account each local specificity that we will be able to unlock its full potential,” Benoit Potier, Chairman and CEO of Air Liquide and Co-Chair of the Hydrogen Council said. He said it will require a combination of several renewable and low carbon pathways, facilitated by favorable regulations, as well as further industrial developments for low carbon hydrogen technologies. The report says there is not one single hydrogen production pathway to achieve low lifecycle greenhouse gas (GHG) emissions, but rather the need is for a fact-based approach that leverages regional resources and includes a combination of different production pathways. This will help in achieving emissions and cost reductions helping in the decarbonization of the energy system and limiting global warming. The report explores three hypothetical hydrogen supply scenarios to measure the feasibility and impact of deploying renewables and low carbon hydrogen at scale. “While green hydrogen produced through water electrolysis with renewable power achieves the lowest emissions, blue hydrogen produced from natural gas with high CO2 capture rate and storage can also achieve low emissions if best technologies are used and best practises followed,” the report says. Across the eight illustrative pathways explored in the report, analysis has shown that GHG emission reductions can be made as much as 60-90 per cent or more compared to conventional fossil fuels. The report concludes that low-carbon hydrogen supply at scale is fully achievable. After investigating two hypothetical boundary scenarios (a green only and blue only scenario) to assess the feasibility and impact of decarbonized hydrogen supply, the report found that both the scenarios are feasible. They are not limited by the world’s renewables potential or carbon sequestration capacities (CCS). The Hydrogen Council's data released in January 2020 showed that a wide range of hydrogen applications can become competitive by 2030, driven by falling costs of renewables and low carbon hydrogen. |
