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. The theoretical minimum voltage needed to split water molecules into hydrogen and oxygen is 1.23 Nanosystem for water electrolysis. This lowers the system cost of what is essentially an electrolysis process.

Eneos opens demo plant in Australia to produce MCH liquid organic hydrogen carrier

Green Car Congress

ENEOS Corporation has constructed a demonstration plant in Brisbane, Australia, to produce methylcyclohexane (MCH), a liquid organic hydrogen carrier (LOHC), using its proprietary low-cost electrochemical synthesis of organic hydride method Direct MCH. Eneos’ Direct MCH uses an electrolyzer to produce MCH directly from water.

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. Larger scale C2CNT can be achieved through direct elimination of atmospheric CO 2 using solar heat and solar to electric PVs. Monel cathode substrates, electrolyte equilibration, and a mixed metal (NiChrome) nucleation facilitate the synthesis of this CNT wool.

Energy Vault to provide 1.6 GWh of gravity energy storage to support DG Fuels SAF projects

Green Car Congress

Energy Vault’s advanced gravity energy storage solutions are based on the proven physics and mechanical engineering fundamentals of pumped hydroelectric energy storage, but replace water with custom-made composite blocks, or “mobile masses”, which do not lose storage capacity over time.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

The technology could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and sun far more economical and reliable. Solid-electrode batteries maintain discharge at peak power for far too short a time to fully regulate wind or solar power output.

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

Green Car Congress

Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. 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.

Hydrogen Optimized to supply more than 40 MW of large-scale hydrogen production capacity

Green Car Congress

has entered into a confidential Letter of Intent (LOI) with a large industrial company to provide more than 40 MW of RuggedCell water electrolyzer capacity for hydrogen production. RuggedCell water electrolysis technology was designed from the start to offer important capabilities which were missing in the market. —Andrew T.
