GWU team suggests C2CNT carbon nanotube composites could amplify reduction of GHG emissions

Green Car Congress

Stuart Licht reports that the addition of carbon nanotubes (CNTs) produced from CO 2 by low-energy C2CNT (CO 2 to CNT) molten electrolysis ( earlier post ) to materials such as concrete or steel not only forms composites with significantly better properties, but amplifies the reduction of CO 2. A) Carbon mitigation with CNT-cement. (B)

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

When including the cost of storage and pipeline infrastructure, the delivered cost of renewable hydrogen in China, India and Western Europe could fall to around $2/kg ($15/MMBtu) in 2030 and $1/kg ($7.4/MMBtu) Note: Clean hydrogen refers to both renewable and low-carbon hydrogen (from fossil-fuels with CCS).

AQDSH 2 refers to the reduced form of AQDS. AQDS undergoes extremely rapid and reversible two-electron two-proton reduction on a glassy carbon electrode in sulfuric acid. First, scalability: AQDS contains only the Earth-abundant atoms carbon, sulphur, hydrogen and oxygen, and can be inexpensively manufactured on large scales.

C-Zero raises $11.5M Series A to produce clean hydrogen from natural gas via methane pyrolysis

Green Car Congress

C-Zero’s technology, which was initially developed at the University of California, Santa Barbara, uses innovative thermocatalysis to split methane into hydrogen and solid carbon in a process known as methane pyrolysis. The methane decomposition reaction is moderately endothermic; the energy requirement per mole of hydrogen produced (8.9

Global study shows uneven urbanization among large cities in the last two decades

Green Car Congress

China will reach carbon emission peak before 2030 and carbon neutrality by 2060, and large cities with a significant greening trend play an important role in neutralizing carbon emission and mitigating the impact of global climate change in urban areas.

Nitrogen-doped graphene nanoplatelets offer high catalytic performance in fuel cells and solar cells; possible replacement for Pt

Green Car Congress

Researchers in South Korea have developed a simple, low-cost and eco-friendly method of creating nitrogen-doped graphene nanoplatelets (NGnPs) with excellent catalytic performance in both dye-sensitized solar cells and fuel cells to replace conventional platinum (Pt)-based catalysts for energy conversion. —Jeon et al.
