Research into carbon capture and sequestration has shown both promise and disappointment. A 2010 study indicated that “negative emission technologies…significantly enhances the possibility to meet low concentration targets” (Azar et al, 2010). The American Geophysical Union has also called for further research (Landau, 2018). A recent article published in the Cambridge University Press called for a research agenda on NETS and stated: “There are many technological solutions to address climate change but unfortunately there are no silver bullets” (Nekuda, 2019).
A 2016 paper called the assumption that these technologies and concepts will work to scale in time a “moral hazard” (Anderson & Peters, 2016). However, Friedmann responded by saying “CO2 removal has gone from a moral hazard to a moral imperative.” (Welch, 2019).
As succinctly stated in Physics Today, we need increased R&D to scale NETs (Kramer, 2020). As explained by Dr Glen Peters from the Centre for International Climate and Environmental Research “we need to focus on getting things deployed that we know already work and at the same time we also need to focus on developing new technologies that will help us go the last part of the journey,” (McGrath, 2017).
Roger Aines, the chief scientist of the energy program at Lawrence Livermore National Laboratory explained, “we have to get started” with widely employing technologies capable of removing CO2 from the air. “It’s the question of how to get started,” he said (Ross, 2018).
