Geely’s CRI investment and work with renewable methanol is similar to the approach Audi is taking with its own e-fuels projects—producing very low carbon liquid or gaseous fuels using only renewable energy, water and CO 2. Their results showed that in comparison with gasoline mode, CO emitted in methanol mode decreased 11.2%.

Comparison with conventional Cu/ZnO/Al2O3 catalysts revealed the same or better methanol synthesis activity, as well as considerably lower production of CO. Another challenge arises with the use of CO-free CO 2 , which will lead to CO as a by-product of methanol via the reverse water–gas shift (rWGS) reaction. —Studt et al.

The Precourt Institute for Energy, the umbrella organization for energy research and education at Stanford, will fund the following four studies: Nanostructured Polymers for High-Performance Batteries. This project explores the use of specially designed nanostructured polymers to make high-energy, low-cost, flexible and stretchable batteries.

mgPt cm -2 ) is shown for comparison (dashed line). The prohibitive cost of platinum for catalyzing the ORR has hampered the widespread use of polymer electrolyte fuel cells. For all intents and purposes, this is a zero-cost catalyst in comparison to platinum, so it directly addresses one of the main barriers to hydrogen fuel cells.

Pyrolysis bio-oils are produced by the thermal decomposition of biomass by heating in the absence of oxygen at more than 500 °C; fast pyrolysis of biomass is much less expensive than biomass conversion technologies based on gasification or fermentation processes. In comparison, increasing the H/C eff ratio of pyrolysis oil from 0 to 1.4

An NREL report summarizing the 2011 Alkaline Membrane Fuel Cell Workshop noted that: In comparison with PEMFCs, AMFCs offer the advantage of avoiding Pt or Pt group metal (PGM) electrocatalysts, one of the primary limitations in the commercial deployment of fuel cells. … An alternative is the alkaline environment of the AEMFC.

To release the sugars locked into the cellulose polymers in biomass, producers use both physical and chemical methods, with physical chemical pretreatment processes followed by enzymatic hydrolysis being the most common, note Raines and Binder. Furthermore, the hydrolysate products are readily converted into ethanol by microorganisms.
