Different CO2 utilization technologies are currently of interest as it is unlikely for just one technology to be the solution for climate change, but rather the combination of many sustainable technologies. In this op-ed, Geoff introduces the concept of Li-CO2 … Continue reading →

In order to minimize the effects of climate change, net greenhouse gas (GHG) emissions must be reduced to zero. In this op-ed, Geoff details how GHG-emitting technologies are being displaced by more environmentally friendly technologies, but also touches on some … Continue reading →

In the inaugural issue of Joule, Geoff provided a commentary on Prof. Steinfeld’s work on CO2 reduction. Their current photo-thermal reactor design implementing a CeO2 catalyst is described with insight into the chemistry of how the originally multistep process has … Continue reading →

In this op-ed, Geoff makes a case for CO2 sourced synthetic fuels despite the growing electrification trend in transportation. Key points in the production-use-end life cycle of each path is highlighted for considering whether the production and use of CO2 … Continue reading →

In celebration of Geoff’s 74th birthday, a vignette of his past 50 years of scientific contributions is featured. Geoff’s work on nanochemistry began with with the controlled nucleation and growth of ‘naked’ metal atoms in cryogenic conditions and has since … Continue reading →

With the development of an all electric autonomous cargo ship by Kongsberg and Yara International, is the need for synthetic CO2-based fuels diminishing? In this op-ed, Geoff discusses the state of electrification and the continued need for CO2-based fuels. The … Continue reading →

Congratulations to Jia on her two recently published papers! Her review published in ChemSocRev covers the broad field of how defects in metal oxides play a role in the heterogeneous catalytic hydrogenation of CO2. Her paper published in Avanced Science … Continue reading →

In this op-ed, Geoff outlines the roadmap to achieving CO2 utilization on a gigaton scale, detailing four missions: to utilize atmospheric CO2, recycle CO2 from combustion sources, prevent CO2 being released into the atmosphere, and boost CO2 sinks on the … Continue reading →

Despite hydrogen having the largest known gravimetric energy storage capacity (33kWh/kg), its storage requires prohibitively low temperatures or high pressures. In this op-ed, Geoff describes the use of liquid organic hydrogen carriers to effectively access hydrogen hydrogen storage. The full … Continue reading →

Transportation is well known to generate a large fraction of the world’s anthropogenic CO2, which consequently produces negative consequences for future transportation, specifically aviation. In this op-ed, Geoff highlights the effect of climate change on aviation, including intensification of clear … Continue reading →
