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.
Each credit one metric ton of carbondioxide 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.

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 carbondioxide (0.035% volume mixing ratio), and ozone.
With atmosphericcarbondioxide 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.
of the world’s total carbondioxide 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.
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-carbonbiofuel, it will have 86% fewer emissions than a fossil-fuel rocket.
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 carbondioxide over 20 years.
The law provides $140 billion in tax incentives, direct loans, and grants to replace fossil fuels with cleaner renewable energy that lowers emissions of carbondioxide. Gevo asserts its “farm-to-flight” project will release 80 percent less carbondioxide to the atmosphere than ethanol produced by a conventional plant.
The executive order will include training programs for biotechnology workers and is expected to cover sectors from pharmaceuticals to biofuels and agricultural food supplies. NASEM: The Board on Atmospheric Science and Climate released a review of the U.S. 12, aimed at boosting the U.S. CEQ must receive nominations by Sept.
32] Part of the reason the planet is greening stems from greater carbondioxide in the atmosphere, and greater planetary warming. [33] 33] Scientists find that plants grow faster as a result of higher carbondioxide concentrations. 34] All else being equal, it would be best for global temperatures to remain stable.
