Wärtsilä hybrid propulsion system with methanol engine to power four SAL heavy lift vessels; wind farm installations

Green Car Congress

The Energy Storage system will be based on Lithium-Titanium-Oxide (LTO) batteries, which can handle higher amounts of deep cycles than normal Lithium-ion based systems. The ships are scheduled for delivery in 2025 and will be used mainly to support wind farm installations.

Axion supplying PbC batteries to Norfolk Southern for all-battery switcher and working on line-haul hybrid locomotives; micro-hybrid and stationary expansion

Green Car Congress

The battery-electric NS-999, “under the long hood”. In April, Axion Power International Inc received an order from Norfolk Southern Corp (NS) for PbC lead-carbon batteries for use in an all-battery-powered switcher locomotive. To date, this is the largest single PbC battery order that Axion has received. PbC batteries.

PNNL study outlines requirements for grid storage, reviews four electrochemical energy storage systems: vanadium redox flow, Na-beta, Li-ion and lead-carbon

Green Car Congress

published in the ACS journal Chemical Reviews , reviews in detail four stationary storage systems considered the most promising candidates for electrochemical energy storage: vanadium redox flow; sodium-beta alumina membrane; lithium-ion; and lead-carbon batteries. Among the most important factors are capital cost and life-cycle cost.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Typical ultracapacitors are characterized by high power density compared to batteries (but poor energy density), as well as quick charge and discharge. Ioxus is also interested in working with battery companies on integrated solutions. Two lithium-ion battery companies are working with us now. Earlier post.).

Proud of its roots

Electric Auto Association

I ordered a controller from a company in California, which used a single power Darlington transistor, and 4 deep cycle 12-volt batteries.” We like to do in person meetings when we can actually visit something,” he continued, describing chapter trips to battery manufacturing plants, wind farms, and the solar array at the U.S.
