Gigastack renewable hydrogen from offshore wind project advances to next phase; 100MW electrolyzer system

Green Car Congress

The Gigastack project, led by ITM Power, Ørsted, Phillips 66 Limited and Element Energy, will show how renewable hydrogen derived from offshore wind can support the UK’s 2050 net-zero greenhouse gas emission target. from an offshore wind farm—the process of producing hydrogen from water (electrolysis) can be decarbonized.

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. MCH contains more than 500 times more hydrogen per unit volume than hydrogen gas.

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. Carbon dioxide is the sole reactant in this CNT transformation, providing a financial impetus for the removal of this greenhouse gas. Monel cathode substrates, electrolyte equilibration, and a mixed metal (NiChrome) nucleation facilitate the synthesis of this CNT wool.

UK awards £28M for 5 demonstration-phase low-carbon hydrogen production projects

Green Car Congress

The Dolphyn project showcases a floating semi-submersible design with an integrated wind turbine, PEM electrolysis and desalination facilities. The project concerns the production of hydrogen at scale from offshore floating wind in deep water locations. The project aims to reduce the cost of electrolytic hydrogen significantly.

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.
