摘要：
2022 年底，ICAO 成员国通过了一项长期全球理想目标（LTAG），即到 2050 年实现国际航空净零碳排放。然而，迄今为止，尚未有人提出一种可在经济上规模化的航空脱碳解决方案。尽管人们已对包括电子燃料、可持续航空燃料（SAF）、氢或氨在内的潜在替代燃料进行了大量研究，并对纯电推进开展了广泛研究，但低碳推进方法仍无法以相同或更优的经济性取代化石燃料。当前推进技术的一种可能替代方案，是将飞机所需的推进功率直接波束传输给飞机。迄今为止，已有若干技术得到考虑，尤其是激光能量传输和微波能量传输。本文提出了一种可能的概念：未来客机主要由地面产生的电力供能。随着太阳能电池板制造预期的改进与规模化，即使按照当前喷气燃料价格，所提出的概念也将具有经济竞争力，同时大幅减少 CO2 排放。
英文摘要：
In late 2022, ICAO member states adopted a long-term global aspirational goal (LTAG) to achieve net zero carbon emissions from international aviation by 2050. To date however, no economically scalable solution to the aviation decarbonization problem has been proposed. Despite considerable research on potential alternative fuels including e-fuels, Sustainable Aviation Fuel (SAF), Hydrogen or Ammonia, and extensive research on purely electric propulsion, low-carbon propulsion methods are unable to replace fossil-fuels with identical or better economics. A possible alternative to current propulsion technologies is to directly beam the required propulsive power to aircraft. Several techniques have been considered to date, in particular laser energy beaming and microwave energy beaming. This paper proposes a possible concept where future airliners are mostly powered with ground-generated power. With expected improvements and scaling in solar panel manufacturing, the proposed concept would be economically competitive even with current jet fuel prices, while considerably reducing CO2 emissions.
