论文摘要
天文学的碳足迹的很大一部分源于化石燃料，供应天文学的电压需求。在这里，我们探索了新计划的Atacama大型孔径望远镜的各种孤立的低碳电源设置，并将它们与一个普遍存在的柴油发电系统进行比较。设计系统中包括的技术是光伏，集中的太阳能，柴油发电机，电池和氢气存储。我们将电力系统优化模型大大调整到该案例研究中，并以望远镜预计的能源需求，2030年的成本假设以及特定于现场的容量因素为基础。我们的结果表明，LCOES的最低成本系统为$ 116/MWH，主要使用Photovoltaics与电池和燃料电池配对，并在进口和现场生产的绿色氢中运行。一些柴油发电机运行以进行备份。与企业相比，该解决方案将使望远镜的电力碳足迹减少95％。
A large portion of astronomy's carbon footprint stems from fossil fuels supplying the power demand of astronomical observatories. Here, we explore various isolated low-carbon power system setups for the newly planned Atacama Large Aperture Submillimeter Telescope, and compare them to a business-as-usual diesel power generated system. Technologies included in the designed systems are photovoltaics, concentrated solar power, diesel generators, batteries, and hydrogen storage. We adapt the electricity system optimization model highRES to this case study and feed it with the telescope's projected energy demand, cost assumptions for the year 2030 and site-specific capacity factors. Our results show that the lowest-cost system with LCOEs of $116/MWh majorly uses photovoltaics paired with batteries and fuel cells running on imported and on-site produced green hydrogen. Some diesel generators run for backup. This solution would reduce the telescope's power-side carbon footprint by 95% compared to the business-as-usual case.
