根据可持续能源系统的关键标准，分析了氢气在世界和德国长期可持续能源情景中的作用。氢在长期能源情景中的可能范围是广泛和不确定的，这取决于对所使用的一次能源、技术组合、能源效率提高的速度和成本下降(“学习效应”)的假设。无论如何，可持续能源战略必须把提高能效放在最重要的位置，同时加快可再生能源的市场推广(“综合战略”)。在这种情况下，氢气将在2030年前发挥主要作用，利用天然气作为通往可再生氢气的桥梁。在德国正在讨论一项雄心勃勃的二氧化碳减排目标的背景下，根据最新的可持续能源情景，分析了提高能效的潜力、发电厂系统必要的结构变化(对应于逐步淘汰核能的决定、运输部门的转型和可再生能源的市场实施顺序(“首先为发电、然后用于供热、然后用于运输部门的效率准则”))。
The role of hydrogen in long run sustainable energy scenarios for the world and for the case of Germany is analysed, based on key criteria for sustainable energy systems. The possible range of hydrogen within long-term energy scenarios is broad and uncertain depending on assumptions on used primary energy, technology mix, rate of energy efficiency increase and costs degression (“learning effects”). In any case, sustainable energy strategies must give energy efficiency highest priority combined with an accelerated market introduction of renewables (“integrated strategy”). Under these conditions hydrogen will play a major role not before 2030 using natural gas as a bridge to renewable hydrogen. Against the background of an ambitious CO2-reduction goal which is under discussion in Germany the potentials for efficiency increase, the necessary structural change of the power plant system (corresponding to the decision to phase out nuclear energy, the transformation of the transportation sector and the market implementation order of renewable energies (“following efficiency guidelines first for electricity generation purposes, than for heat generation and than for the transportation sector”)) are analysed based on latest sustainable energy scenarios.
