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.

HyperSolar reaches 1.25 V for water-splitting with its self-contained low-cost photoelectrochemical nanosystem

Green Car Congress

volts (V) of water-splitting voltage with its novel low-cost electrolysis technology. Further, overcoming the corrosive degradation of these “artificial photosynthesis” systems remains a challenge and has thus far eluded commercialization. HyperSolar, Inc. announced that it had reached 1.25 V (at 25 °C at pH 0).

Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The module developed at Rice University can be immersed into water directly to produce fuel when exposed to sunlight. That lowers the entry barrier for commercial adoption.

Stanford team reports new low-cost, non-precious metal catalyst for water splitting with performance close to platinum

Green Car Congress

Researchers at Stanford University, with colleagues at Oak Ridge National Laboratory and other institutions, have developed a nickel-based electrocatalyst for low-cost water-splitting for hydrogen production with performance close to that of much more expensive commercial platinum electrocatalysts.

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

Green Car Congress

A team led by Dr. 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. Currently, perovskite instability limits the cell lifetime.)
