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.

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

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF). Abatement cost with hydrogen at $1/kg (7.4/MMBtu).

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.

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.

US DOE to award $4M to support projects on hydrogen delivery technology for fuel cell vehicle refueling

Green Car Congress

DOE’s long-term goal of production and delivery research and development (R&D) is a high-volume hydrogen cost goal of $2-$4 per gallon gasoline equivalent (gge) (produced, delivered and dispensed, but untaxed) to allow FCEVs to be competitive on a dollar per mile basis with gasoline in hybrid electric vehicles.

SEAT pushes forward with CNG line-up

Green Car Congress

As well as ecological and tax benefits, TGI technology offers exceptionally low costs per kilometer—up to 50% cheaper than a gasoline equivalent model and 30% cheaper than a diesel—and with the further improvements SEAT has made to the technology, now it can go even further before needing to be refueled.
