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. The two main components—the electrochemical conversion hardware through which the fluids are flowed (which sets the peak power capacity) and the chemical storage tanks (which set the energy capacity)—may be independently sized. Cell schematic. Huskinson et al. Click to enlarge.

Transphorm and ON Semiconductor begin production of co-branded 600V GaN cascode transistors

Green Car Congress

At APEC 2015, ON Semiconductor and power conversion specialist Transphorm, building on their previously announced partnership to bring gallium nitride (GaN) based power solutions to market, introduced the co-branded NTP8G202N (TPH3202PS) and NTP8G206N (TPH3206PS) 600V GaN cascode transistors and a 240 W reference design that utilizes them.

Nitrogen-doped graphene nanoplatelets offer high catalytic performance in fuel cells and solar cells; possible replacement for Pt

Green Car Congress

Researchers in South Korea have developed a simple, low-cost and eco-friendly method of creating nitrogen-doped graphene nanoplatelets (NGnPs) with excellent catalytic performance in both dye-sensitized solar cells and fuel cells to replace conventional platinum (Pt)-based catalysts for energy conversion. —Jeon et al.

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. In this discovery of the C2CNT-composite process, carbon nanotubes are produced by electrolysis at low cost consuming, rather than releasing, CO 2 , and then mixed with the structural material. (B) Carbon mitigation with CNT-Al. Licht et al.

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.

ARPA-E adds five new funding topics to FOA to advance critical energy innovation

Green Car Congress

Direct removal of CO 2 from the atmosphere, sometimes referred to as direct air capture (DAC), is the separation of CO 2 at ambient concentration (about 410 parts per million by volume fraction (ppmv)) from air. ARPA-E seeks to establish robust, energy efficient, and low-cost strategies for direct removal of carbon dioxide from ambient air.

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

Researchers from Ulsan National Institute of Science and Technology (UNIST) in Korea and Karlsruher Institute of Technology in Germany have developed a novel energy conversion and storage system using seawater as a cathode. In addition, this system can be easily scaled up.
