Decarbonizing Planet Earth – Nuclear vs. Renewable

Adding to the controversial scientific debate whether renewable or nuclear energy decarbonize the atmosphere quicker, Lovins et al of the Rocky Mountain Institute in Basalt, Colorado, argue that renewable energy is doing a better job. In their recent study, published in Energy Research & Social Science, they analyzed 17 years of recent energy resource development worldwide to support their conclusion. Their paper stands in contrast to numerous previous studies, including a 2016 report published by Cao et al in Science, claiming that nuclear power is better suited for fast decarbonization. However, the nuclear waste problem still remains unresolved.

Starting up Power-to-Gas Reactors

In their paper “Effect of Start-Up Strategies and Electrode Materials on Carbon Dioxide Reduction on Biocathodes“, which was recently published in Applied and Environmental Microbiology, Saheb-Alam et al. teach us how to start-up bio-electrical systems for CO2 conversion to methane gas. They compared pre-acclimated with pristine electrodes and found that there is no difference in start-up time. Their findings stand in contrast to previous observations where pre-acclimation has indeed helped to improve reactor performance. For example, LaBarge et al. found that electrodes acclimated with methane-forming microbes, called Methanobacterium, do reduce start-up time.
