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

Green Car Congress

AQDSH 2 refers to the reduced form of AQDS. Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. Flow batteries store energy in chemical fluids contained in external tanks, as with fuel cells, instead of within the battery container itself.

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

Green Car Congress

When renewable natural gas is used as the feedstock, C-Zero’s technology can even be carbon negative, effectively extracting carbon dioxide from the atmosphere and permanently storing it in the form of high-density solid carbon.

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).

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

Green Car Congress

In the figure "ton" refers to metric tonne and CNT, carbon nanotube. The C2CNT production is achieved at a fraction of the current cost of manufacturing nanotubes and results in a cost of carbon savings in the materials production significantly below the current cost of carbon mitigation.

Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Nanosheets having asymmetric chemical functionalization on opposite faces are commonly referred to as “Janus” graphene, named after a two-faced ancient Roman god. Sodium is an abundant low-cost metal, and a main ingredient in seawater. —Sun et al. The Chalmers researchers devised a novel way to solve this.

8 Products That Excel at Protecting Children’s Digital Privacy

Cars That Think

The platform, which collects minimal data about the students, runs on low-cost and legacy devices. Yoti asks children to authenticate their age and does not store their data. Proof of age includes facial age estimation and reference checks with mobile phone operators or credit agencies. age-appropriate design code.

Lloyd’s Register and UMAS release Zero Emission Vessels 2030 study

Green Car Congress

All analyses are performed against a heavy fuel oil (HFO) reference ship. For those in shipping with niche access to a low-cost supply of zero-emission fuel or energy sources, or an ability to pass on a voyage cost premium to a supply chain that values zero-emission services, the gap may already be closed.
