Hybrid biomass flow battery stores electricity and produces valuable chemicals at the same time

Green Car Congress

Rechargeable batteries store electricity in their electrode materials, while redox flow batteries use chemicals stored in tanks attached to the electrodes. Researchers have now developed a battery system based on a hybrid cell, which not only stores and provides electricity but also produces valuable chemicals in a flow system.

SoCalGas, H2U testing new Gramme 50 electroylzer for green hydrogen production

Green Car Congress

(SoCalGas) and H2U Technologies are testing a new electrolyzer, called the Gramme 50, for the production of green hydrogen. The Gramme 50 electrolyzer features a radically different stack design to achieve high current density and outlet pressure requirements.

H2Carrier and Anori developing PtX project in Greenland; production of green ammonia on floating platform P2XFloater

Green Car Congress

H2Carrier AS and Greenland-based Anori A/S have signed a Letter of Intent (LOI) with the purpose of developing the first commercial wind farm in Greenland with subsequent production and export of green ammonia. The 1.5GW wind farm will supply power to H2Carrier’s floating production vessel for hydrogen and green ammonia, the P2XFloater.

Nornickel investigating using mining tailings to capture and store CO2

Green Car Congress

Russia-based Norilsk Nickel (Nornickel)—the world’s largest nickel producer—is studying the potential for mining tailings to capture and store CO 2. As a waste, tailings are stored in designated storage facilities called tailing dams. In 2021, Nornickel extracted 41.2 mm) that looks like sand.

Provaris receives ABS approval for design of H2Neo compressed hydrogen carrier

Green Car Congress

Australia-based Provaris Energy has received class approval from the American Bureau of Shipping (ABS) for the design of Provaris’ 26,000 m 3 H2Neo compressed hydrogen carrier, the first of its kind to receive this level of approval. The tanks are designed so that they cannot suddenly rupture and release a catastrophic amount of energy.

IIT, Argonne team designs Li2O-based Li-air battery with solid electrolyte; four-electron reaction for higher energy density

Green Car Congress

In past lithium-air designs, the lithium in a lithium metal anode moves through a liquid electrolyte to combine with oxygen during the discharge, yielding lithium peroxide (Li 2 O 2 ) or superoxide (LiO 2 ) at the cathode. This chemical sequence stores and releases energy on demand. —Kondori et al.
