PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure).

DOE awards $22.1M to 10 nuclear technology projects including clean hydrogen production

Green Car Congress

million to 10 industry-led projects to advance nuclear technologies, including two aimed at expanding clean hydrogen production with nuclear energy. A well-established downstream syngas-to-synfuel conversion process, such as Fischer-Tropsch synthesis, converts the syngas to liquid synfuel for a total projected cost of less than $4/gallon.

Researchers develop earth-abundant photocatalyst for conversion of ammonia into hydrogen

Green Car Congress

This result demonstrates the potential for highly efficient, electrically driven production of hydrogen from an ammonia carrier with earth-abundant transition metals. This discovery paves the way for sustainable, low-cost hydrogen that could be produced locally rather than in massive centralized plants. —Yuan et al.

KIST team develops membrane reactor system to produce pure H2 from ammonia with high productivity

Green Car Congress

Researchers at the Korea Institute of Science and Technology (KIST) have developed a steam-carrier-adopted composite membrane reactor system to produce pure H 2 (>99.99%) from ammonia with high productivity (>0.35 1 ) and ammonia conversion (>99%) at a significantly reduced operating temperature (. mol-H 2 g cat ?1 Credit: KIST.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Herein, we demonstrate a sulfur looping scheme in a one-reactor system using a low-cost and environmentally safe iron-based sulfur carrier. Compared with the undoped sulfur carrier, Mo dopant facilitates the surface hydrogen diffusion, thus promoting the overall H 2 S conversion. —Jangam et al. 1c03410.

Georgia Tech team develops melt-infiltration technique for scalable production of solid-state batteries

Green Car Congress

A new fabrication technique could allow all-solid-state automotive lithium-ion batteries (ASSLBs) to adopt nonflammable ceramic electrolytes using the same production processes as in batteries made with conventional liquid electrolytes. In the study, the team used this energy-efficient method to fabricate inorganic ASSLBs with LiNi 0.33
