ARPA-E awards $38M to 12 projects leading used nuclear fuel recycling initiative

Green Car Congress

While used nuclear fuel, sometimes referred to as spent nuclear fuel, is created during the process of generating nuclear energy, clean energy generated from this fuel would be enough to power more than 70 million homes. Upon discharge from a nuclear reactor, the UNF is initially stored in steel-lined concrete pools surrounded by water.

LOTTE, Sumitomo of Americas and Syzygy Plasmonics to partner on photocatalytic cracking of ammonia to produce hydrogen

Green Car Congress

Plans include importing green ammonia that can be readily transported and stored before it is converted into clean hydrogen with expectations of generating 1.2 The traditional thermal cracking of ammonia uses high heat and pressure to convert it to hydrogen gas. million tons of hydrogen per year domestically by 2030.

New composite reduces rare earth element usage in three-way catalytic converters

Green Car Congress

The high-performance, three-way catalytic (TWC) converter is one of the workhorses of emissions reduction for gasoline engines. Ce is an essential element in oxygen-storage materials that reversibly stores and releases large amounts of oxygen depending upon the partial oxygen pressure in the gas phase. —Machida et al.

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

pre- and post- decarbonization of the electric power sector—to which he referred as pre-CCS and post-CCS, respectively (although decarbonization was not necessarily via CCS—carbon capture and storage).) When that carbon is converted into a fuel, burned, and exhausted to the atmosphere, the overall cycle is roughly neutral.

DICP vanadium redox flow battery hits 10,000 charge/discharge cycle mark

Green Car Congress

A redox flow battery (RFB) stores electrical energy typically in two soluble redox couples contained in external electrolyte tanks sized in accordance with application requirements. The electrolytes flowing through the cathode and anode are often different and are referred to as anolyte and catholyte, respectively.

Ideal Power, developer of new indirect power conversion technology, prices IPO

Green Car Congress

PPSA has a 100% indirect power transfer compared to direct power transfer from conventional power converters. All the energy runs through, and is temporarily stored in, a high-frequency AC link consisting of an inductor and capacitor. Ideal Power Inc. The system is designed to allow power to flow in any mix among any ports with 96.5%

Kopernikus Project P2X integrated container-scale test facility produces first fuels from air-captured CO2 and green power

Green Car Congress

Dittmeyer suggests that is thus only reasonable to store unused green power in chemical energy carriers. 60% of the green power used can be stored in the fuel as chemical energy. —Professor Roland Dittmeyer, KIT, coordinator of the “Hydrocarbons and Long-chain Alcohols” research cluster of the Power-to-X (P2X) Kopernikus project.
