Producing sustainable e-fuels like ethanol and butanol requires the processing of biofeedstocks. Using microbes to chew their way through them is well known. Justin Rickard at NREL describes research there that has found a much more efficient way, using electron-bifurcating enzymes. Flavin-based bifurcating enzymes are biocatalysts that have evolved to perform efficient metabolic reactions in harsh environments with low nutrients. The researchers … [Read more...]
Methane Removal: an overlooked climate solution that could cut temperatures by 1°C?
If you think CO2 removal isn’t getting enough attention, methane removal is getting virtually none. There are attempts to reduce methane emissions directly from fossil fuel production. But Rob Jordan at the Stanford Woods Institute for the Environment describes studies and models that conclude we should be looking at large and wide scale reduction and capture of methane. A 40% reduction in global methane emissions by 2050 could reduce peak … [Read more...]
