NREL study finds high-pressure hydrogen pipeline system could potentially make hydrogen cost-competitive with gasoline

Green Car Congress

About half of the levelized cost of retail station hydrogen can be attributed to hydrogen delivery, compression, and dispensing costs. Department of Energy (DOE) estimates that a dispensed cost of about $7/kg must be achieved to make FCEVs competitive with gasoline internal combustion engine vehicles in early FCEV markets.

U Waterloo, GM R&D team develops new very high-performance silicon-sulfur-graphene electrode for Li-ion batteries

Green Car Congress

Current LIBs [Li-ion battery] systems utilize graphite anodes, where energy is stored by intercalating lithium into the graphite layers. However, the limitation in electrode loading and the high cost of high temperatures have led us to think of a new electrode design.

OSU hybrid “solar battery” uses photo-assisted charging to improve performance of Li-air batteries; “negative overpotential”

Green Car Congress

The basic concept of the integrated solar battery is to use the contribution of the photovoltage to reduce greatly the charging overpotential caused by the difficulty in efficiently electrochemically decomposing lithium peroxide (Li 2 O 2 ), the discharge product formed on the oxygen electrode. Any time you can do that, you reduce cost.

Enter BMW — with Carbon Fiber

Revenge of the Electric Car

2009 BMW Concept ActiveE. Here’s the full text of the entire article, in case the link goes bad: [link]. The total cost of the plant will exceed $100 million, and some 80 jobs are expected to result. All MegaCity cars will run solely on electricity stored in a 16-kilowatt-hour lithium-ion battery pack. Early tests.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

US $5 PER KILOGRAM Cost of green hydrogen today. And the Norwegian company H2Carrier recently received approval in principle for its concept for an industrial-scale floating production unit to make green ammonia at sea. The trick will be to keep the cost of these buffers to a minimum. Conventional, or gray, hydrogen: $1.50

Volvo XC40 Recharge and Polestar 2: EV cousins offer different takes on “premium”

Charged EVs

Android running the dashboard means Google Assistant, Google Maps, Google Play Store, and more, are instantly available and work the way you already use them. Polestar itself is in the process of setting up its company stores, a process obviously affected by the global COVID pandemic now entering its second year. Watch this space.
