Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

For comparison, the US DOE’s 2020 target for the levelized cost of hydrogen (production only) is $2.30/kg. The results from this study suggested a cost of hydrogen as low as ¥17 to ¥27/Nm 3 (US$0.16 - $0.25) using a combination of technologies and the achievement of ambitious individual cost targets for batteries, PV, and electrolyzers.

Tesla to Adapt Bi-Directional Chargers by 2025

Get Electric Vehicle

Any electric vehicle that is linked to a smart charging station or has an internet connection can have a controllable load, or the ability to choose when an EV charges. What is Bidirectional Charging? The enormous size of the battery pack, particularly in a Long Range EV. The current Powerwall has a total energy capacity of 13.5

Renault makes public its lifecycle study of Fluence ICE vs Fluence EV

Green Car Congress

Renault’s comparison of the carbon footprint of EV and ICE vehicles over production, operation and end of life. is shown with both UK and French grid mixes. Further, due to the variation in the power grid mix from one country to another, the benefits of the EV varies significantly based on that grid mix.

New PNNL zinc-polyiodide redox flow battery offers 2x energy density of next-best system; potential for mobile applications

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have developed a new zinc-polyiodide redox flow battery offering more than two times the energy density of the next-best flow battery used to store renewable energy and support the power grid. Hoses were connected between the vials, a pump and a small stack.

How to protect an EV’s on-board charger from transient grid surges – Charged EVs

Baua Electric

In addition to the heat, voltage transients, and electromagnetic interference (EMI) in the automotive environment, the on-board charger must interface with the AC power grid, requiring protection from AC line disturbances for reliable operation. Table 1 lists maximum surge voltages up to 4kV. The IEEE C62.41.2-2002 2002 Standard 1.2/50
