EVs vs Biofuels: new study looks at ethanol’s impact on agricultural land use, food prices, emissions

July 21, 2022 by Josh Gabbatiss

For transport, biofuels have lower emissions than gasoline/petrol, but EVs will have the lowest emissions of all. Hence the opposition to those biofuels, along with objections to the valuable cropland used to make the ethanol. But the overall advantage depends on the speed of transition to EVs charged with clean electricity. Now, a calculation has been made of the amount of agricultural land preserved for global food production - or kept as … [Read more...]

SAFFiRE: cheap, Sustainable Aviation Fuel from agricultural waste

July 6, 2022 by Ryan Horns

SAFFiRE (Sustainable Aviation Fuel From [i] Renewable Ethanol) is a 10-ton-per-day pilot plant project. The goal is 7bn gallons of sustainable, low-carbon aviation fuel by 2040. Ryan Horns at NREL explains that the sustainable fuel is made from corn stover, an agricultural waste product, chemically broken down into sugars that can then be converted to fuels. The SAFFiRE process can take advantage of the existing infrastructure of over 200 ethanol … [Read more...]

Converting captured CO2 directly into fuels could get simpler, cheaper

February 23, 2022 by David Chandler

Converting captured CO2 directly into fuels (or other products) at scale seems an effective way to mitigate emissions. But most of the conversion methods, including electrochemical, thermocatalytic, photothermal, or photochemical processes, have not proved very effective. David Chandler at MIT describes how researchers there have identified the main stumbling block and found a very simple solution. Basically, at the molecular level, the contact … [Read more...]

Engineering yeast to create Biofuels from non-food crops (straw, grass, cellulosic waste)

July 21, 2021 by Anne Trafton

Using ethanol can reduce the global consumption of fossil fuels. But, commercially, ethanol in the U.S. is produced from corn and not enough is grown to make a significant impact on U.S. fuel needs. Anne Trafton at MIT describes research that has engineered yeast to break down straw and woody plant material to create ethanol as efficiently as it’s done from corn. High yields of ethanol were extracted from five different types of cellulosic … [Read more...]

CCUS “gasphilic” process could double the conversion rate of CO2 into useful fuels

February 3, 2021 by David Chandler

Carbon capture and storage (CCS) is proving very expensive. So rather than simply store the CO2 underground it’s better to turn it into something that you can sell. Hence, much work is being directed at turning CO2 into transportation fuels or chemical feedstocks by focussing on the science of reactive materials: the other chemicals in the soup, using different catalysts, and even designing the right nanostructures to maximise the results. MIT’s … [Read more...]
