Abstract

Hydrogen is similar to natural gas in terms of its physical and chemical properties but does not release carbon dioxide when burnt. This makes hydrogen an energy carrier of great importance in climate policy, especially as an enabler of increasing integration of volatile renewable energy, progressive electrification, and effective emission reductions in the hard-to-decarbonize sectors. Leaving aside the problems of transporting hydrogen as a liquid, technological challenges along the entire supply chain can be considered as solved in principle, as shown in the experimental findings of the Hydrogen Innovation Program of the German Technical and Scientific Association for Gas and Water. By scaling up production and end-use capacities and, most importantly, producing hydrogen in regions with abundant renewable energy, hydrogen and its applications can displace natural gas at affordable prices in the medium term. However, this substitution will take place at different rates in different regions and with different levels of added value, all of which must be understood for hydrogen uptake to be successful.

氢气会成为新的天然气吗?天然气电网中的氢整合。
氢气的物理和化学性质与天然气相似,但燃烧时不会释放二氧化碳。这使得氢气成为气候政策中非常重要的能源载体,尤其是作为增加不稳定可再生能源的整合、逐步电气化以及在难以去碳化的部门有效减排的推动力。撇开氢作为液体运输的问题不谈,正如德国天然气与水技术和科学协会氢创新计划的实验结果所示,整个供应链上的技术挑战原则上都可以被视为已经解决。通过提高生产和终端使用能力,最重要的是在可再生能源丰富的地区生产氢气,氢气及其应用可以在中期内以可承受的价格取代天然气。然而,在不同地区,这种替代将以不同的速度进行,并具有不同程度的附加值,要想成功吸收氢气,就必须了解所有这些因素。
