Abstract

Background

Fossil fuels can be replaced with electricity and hydrogen. However, the implementation and use of these low-carbon energy carriers require a sociotechnical transition. This transition might not be completed in time.

Main text

\(\text {CO}_2\)-based methane is a substitute for natural gas that is less carbon-intensive. This methane is synthesized by capturing \(\text {CO}_2\) from air and by performing water electrolysis to produce hydrogen. \(\text {CO}_2\)-based methane is compatible with our current fossil-based society. An analysis of the substitution of natural gas with different energy carriers will be performed, and the results will be compared. The effects of \(\text {CO}_2\)-based methane, hydrogen, and electricity will be evaluated for energy storage, high-temperature level heat production, and residential heating. The multi-level perspective will be applied to assess these energy carriers in the context of our society.

Conclusions

\(\text {CO}_2\)-based methane is the least energy efficient energy carrier among those analyzed. Nevertheless, this type of methane supports the acceleration of the energy transition.

Highlights

CO₂-based methane is a valuable, renewable, and carbon-neutral energy carrier that supports a timely energy transition.
The implementation of hydrogen and electricity requires more modifications to our current sociotechnical society than the implementation of CO₂-based methane.
The urgency of reducing CO₂ emissions is not being considered adequately in the current societal discussion, and a multi-level perspective analysis should provide valuable results that account for the temporal aspect.

\以（text {CO}_2\ ）为基础的甲烷：被忽视的能源转型解决方案

背景电力和氢气可以替代化石燃料。然而，这些低碳能源载体的实施和使用需要社会技术的转型。正文基于（\text {CO}_2\）的甲烷是一种碳密集度较低的天然气替代品。这种甲烷是通过捕捉空气中的\(text {CO}_2\) 并通过电解水来产生氢来合成的。\以（\text {CO}_2\ ）为基础的甲烷与我们当前以化石为基础的社会是兼容的。我们将分析不同能源载体对天然气的替代作用，并对结果进行比较。将对（\text {CO}_2\ ）基甲烷、氢气和电力在储能、高温级制热和居民供暖方面的效果进行评估。多层次的视角将被应用于评估这些能源载体在我们社会中的作用。要点基于二氧化碳的甲烷是一种有价值的、可再生的、碳中性的能源载体，支持及时的能源转型。与使用二氧化碳甲烷相比，使用氢气和电力需要对我们当前的社会技术进行更多的改造。在当前的社会讨论中，没有充分考虑到减少二氧化碳排放的紧迫性，多层次的视角分析应能提供考虑到时间方面的有价值的结果。
