With atmospheric carbon dioxide levels on the rise, “innovative research that finds ways to transform CO 2 in the atmosphere into something positive is more important than ever.” BETO notes that the long-term challenge of the research will be scaling up scientific findings into commercial applications.

Atmosphere The gaseous envelope surrounding the Earth. The dry atmosphere consists almost entirely of nitrogen (78.1% volume mixing ratio), together with a number of trace gases, such as argon (0.93% volume mixing ratio), helium, radiatively active greenhouse gases such as carbon dioxide (0.035% volume mixing ratio), and ozone.

Each credit one metric ton of carbon dioxide equivalent pollution below the standard. I’ve written recently about why a Cap on Vegetable Oil-Based Fuels Will Stabilize and Strengthen California’s Low Carbon Fuel Standard , which addresses the bio-based diesel credits.

H is for Hydrogen ExxonMobil, which spent an estimated $68 million to advertise its $300-million investment in algae biofuels , has pulled the plug on that research and now wants us to put our faith in hydrogen and carbon capture and storage as climate solutions.

of the world’s total carbon dioxide emissions from fossil fuel combustion, many airlines are considering carbon-capture-and-storage technologies and electric-powered planes. One year later , it scheduled more than 200 trial flights between Paris and Amsterdam using biofuel made from used cooking oil.

Less than a quarter of cropland is devoted to food directly eaten by humans, with the rest going to mostly to animal feed and biofuel feedstock, and it takes many pounds of grains to produce a pound of beef. Bovine guts generate methane, which is 85 times more powerful than carbon dioxide over 20 years.

Weighing just 260 kg each, they will fly in very-low-Earth orbit at heights of roughly 550 km, which means that atmospheric drag will pull them down within a few years so they don’t end up as yet more space junk. Powered by ultra-low-carbon biofuel, it will have 86% fewer emissions than a fossil-fuel rocket.
