Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4. The conversion rate reaches 32.9 ± 1.38

EPFL team develops low-cost water splitting cell with solar-to-hydrogen efficiency of 12.3%

Green Car Congress

Michael Grätzel at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland has developed a highly efficient and low-cost water-splitting cell combining an advanced perovskite tandem solar cell and a bi-functional Earth-abundant catalyst. Splitting water requires an applied voltage of at least 1.23 V and up to 1.5

MIT Researchers Identify New Low-Cost Water-Splitting Catalyst

Green Car Congress

Daniel Nocera and his associates have found another formulation, based on inexpensive and widely available materials, that can efficiently catalyze the splitting of water molecules using electricity. Earlier post.). Materials for the new catalyst are even more abundant and inexpensive than those required for the first.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Cost is a greater concern. We decided we needed to develop a new chemistry if we were going to make low-cost batteries and battery electrodes for the power grid.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

The process is constrained by the (low) cost of electricity. Initial scaling is efficiently applied to available concentrated, hot sources of CO 2 , such as eliminating the CO 2 emission from industrial smoke stacks and simultaneously forming valuable CNT wool. —Johnson et al.

KIT team designs low-cost photoreactor for efficient solar-driven synthesis

Green Car Congress

Researchers from the Karlsruhe Institute of Technology (KIT) and their Canadian partners have designed a low-cost photoreactor design for solar-driven synthesis. The photoreactors have a low level of complexity, are readily manufacturable via mass fabrication techniques in polymers, and are easy to adapt to diverse photocatalysts.
