Abstract The 2018 report by the Intergovernmental Panel on Climate Change (IPCC) details how rapidly Earth's climate is changing due to rising atmospheric CO2 concentrations. Maintaining a recognizable terrestrial ecosphere over the next eighty years will require, by 2030, a decrease in global CO2 emissions by 45% from their 2010 levels, with zero net global emissions by 2050. However in 2018, global CO2 emissions were 112% of 2010 levels. Our interest lies in the use of sunlight to efficiently recycle CO2 from a waste combustion product, together with water vapor, into hydrocarbon fuels that can be readily stored, transported and used within the current energy infrastructure. While the concept is intriguing until 2019 such a solar fuels technology has been limited by the vanishingly small CO2-to-fuel photoconversion efficiencies achieved. Recently there has been a significant advance in CO2 to fuel photoconversion efficiencies with researchers achieving, in an unoptimized system, over a 6 h period, a Joule (sunlight) to Joule (fuel) photoconversion efficiency of 1%. Just as photovoltaics went from niche market devices of low photoconversion efficiency to highly efficient devices enabling a global industry, such a sunlight-to-fuel photoconversion efficiency suggest utility-scale implementation of a sunlight-powered recycled-CO2 to hydrocarbon fuel technology is realistically achievable in the near future. With an aim towards enabling significant advances in the field, leading to translation of the technology from laboratory to industrial-scale application, we examine what we believe are the key opportunities for achieving significant advances in sunlight-to-fuel photoconversion efficiencies.

气相CO2减排最新进展综述及未来进展建议

摘要 政府间气候变化专门委员会 (IPCC) 2018 年的报告详细介绍了由于大气 CO2 浓度上升导致地球气候变化的速度。到 2030 年,要在未来 80 年维持一个可识别的陆地生态圈,全球二氧化碳排放量将比 2010 年水平减少 45%,到 2050 年全球净排放量为零。然而,2018 年,全球二氧化碳排放量是 2010 年的 112%水平。我们的兴趣在于利用阳光有效地将二氧化碳与水蒸气一起从废物燃烧产物中回收成碳氢燃料,这些燃料可以在当前的能源基础设施中轻松储存、运输和使用。虽然这个概念在 2019 年之前一直很有趣,但这种太阳能燃料技术一直受到所实现的 CO2 到燃料的光转化效率微乎其微的限制。最近,研究人员在未优化的系统中,在 6 小时内实现了焦耳(阳光)到焦耳(燃料)的光转换效率为 1%,这在 CO2 燃料光转换效率方面取得了重大进展。正如光伏从光转换效率低的利基市场设备转变为支持全球产业的高效设备一样,这种阳光到燃料的光转换效率表明,在公用事业规模上实施太阳能再生二氧化碳到碳氢化合物燃料技术是现实可行的在不远的将来。为了实现该领域的重大进步,将技术从实验室转化为工业规模的应用,
