UCLA team proposes non-photosynthetic biological conversion of CO2

Green Car Congress

Most of us naturally associate biological CO 2 conversion with photosynthesis in plants and algae. Furthermore, the maximum efficiency of solar energy conversion by photosynthesis is 5%, while typical solar panel efficiency reaches 20%. an and Park (2020) “Light-Independent Biological Conversion of CO 2 ,” Joule doi: 10.1016/ j.joule.2020.08.007.

Novel tin-based metal–organic frameworks for reducing carbon dioxide to formate

Green Car Congress

Researchers from Tokyo Tech have developed a tin-based metal–organic framework (MOF) that can photocatalytically reduce carbon dioxide (CO 2 ) into formate under visible light. A popular method for carrying out such conversions is to use visible light for driving the photoreduction of CO 2 via photocatalysts. —Prof. 202305923

Phillips 66 progressing its conversion of California refinery to renewable fuels

Green Car Congress

In April, the company completed the diesel hydrotreater conversion, which will ramp up to 8,000 bbl/d (120 million gallons per year) of renewable diesel production by the third quarter of 2021. Subject to permitting and approvals, full conversion of the refinery is expected in early 2024. Earlier post.).

Penn team proposes liquid-organic hydrogen carriers as endothermic fuels for hypersonic aircraft

Green Car Congress

A team at the University of Pennsylvania is proposing the use of a liquid-organic hydrogen carrier (LOHC)—specifically, 1,2,3,4 -tetrahydroquinoline (THQ)—for use as an endothermic fuel for thermal protection of hypersonic aircraft engines. 1 were obtained, with conversions greater than 80% at 600 °C.

Startup licenses ORNL technology for converting organic waste to hydrogen

Green Car Congress

The technologies work as a system that converts organic waste into renewable hydrogen gas for use as a biofuel. The system combines biology and electrochemistry to degrade organic waste—such as plant biomass or food waste—to produce hydrogen. —Alex Lewis, CEO.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones.

Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

The catalyst shows a carbon dioxide conversion through hydrogenation to hydrocarbons in the aviation jet fuel range of 38.2%, with a yield of 17.2%, and a selectivity of 47.8%, and with an attendant low carbon monoxide (5.6%) and methane selectivity (10.4%). In brief, the Fe–Mn–K catalyst shows a CO 2 conversion of 38.2% Makgae, O.A.
