China team develops efficient multifunctional catalyst for conversion of CO2 to gasoline-range hydrocarbons

Green Car Congress

This catalyst exhibited 78% selectivity to C 5 -C 11 as well as low (4%) CH 4 at a CO 2 conversion of 22% under industrial relevant conditions. Moreover, the multifunctional catalyst exhibited a remarkable stability for 1,000 h on stream, showing potential to be a promising industrial catalyst for CO 2 conversion to liquid fuels.

Sandia-led team demonstrates two efficient hybrid biochemical routes for lignin conversion to value-added chemicals

Green Car Congress

A Sandia National Laboratories-led team has demonstrated two new routes to lignin conversion that combine the advantages of earlier methods while minimizing their drawbacks. Lignin, the tough material left over from biofuel production, contains compounds that can be converted into products such nylon, plastics and drugs.

Researchers in Japan propose a more efficient method to reduce radioactive waste; fast reactor system shortens the lifetime of LLFPs

Green Car Congress

Their approach involves converting radioactive material into short-lived nuclides by absorbing surplus neutrons in the core peripheral portion of a small fast reactor faster than they are generated in the core. Minor actinides are elements synthesized in nuclear fuel other than uranium and plutonium, such as neptunium, americium and curium.

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

The maximum theoretical efficiency of a solar cell is limited by how much photon energy can be converted into usable electrical energy, with photon energy in excess of the semiconductor absorption band edge lost to heat. —Matthew Beard. QDs, which are spherical semiconductor nanocrystals (2-10 nm in diameter), enhance the MEG process.

List of The Best 10 Alternative Fuels for Cars that Could Replace Gasoline

Get Electric Vehicle

Bioethanol is being produced converting carbon-based agricultural feedstock such as sugar cane, bagasse, grain, barley, potatoes. A pneumatic motor which works on expanding compressed air is used to convert the energy to mechanical energy – either linear motion or rotation. Over 2 million electric cars were sold in 2017.

NREL shows graded catalytic-protective layer boosts longevity of high-efficiency photocathodes for renewable hydrogen

Green Car Congress

A PEC cell absorbs sunlight and converts that energy into hydrogen and oxygen by splitting water molecules. However, the slow charge transport kinetics and/or large bandgaps that typically define these oxide semiconductors result in very low energy conversion efficiencies.
