Solar Fuels

We study a range of strategies for the conversion of solar energy to fuels.  Specifically, we first synthesize integrated solar refineries and then build models to study them – identify the major technical bottlenecks and economic drivers. In collaboration with experimental groups, we have studies a range of strategies, including (1) thermochemical splitting of hydrogen and/or carbon dioxide towards the production of Fischer-Tropsch fuels (Kim et al., 2011; Kim et al., 2012), (2) alternative systems for solar ammonia (Wang et al., 2018), and (3) solar methanol (Tountas et al., 2019). We have also developed a general framework for the assessment of such systems (Herron et al, 2015).
