Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Sandia National Laboratories researchers recently delivered electricity produced by a new power-generating system to the Sandia-Kirtland Air Force Base electrical grid. Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity.

Hydrogen Battery "Sponges" Store Solar for the Grid

Cars That Think

A novel project in Australia aims to harness the sun’s energy in two different ways: by storing it and by using it to produce green hydrogen. Operators can use the systems to store energy from solar panels and deliver power to the grid during cloudy days or at night. reduce pressure and add stability to the grid,” Yu said.

million) STORE&GO research project. While the current facility feeds pure hydrogen (“WindGas”) directly into the gas grid, the new methanation plant provides for the generation of “green” methane. This stored energy is then available as backup whenever there is an insufficient supply of solar and wind power.

It selectively filters the hydrogen while blocking other gases, allowing it to be used as a fuel and converted as needed, at the time of re-fueling. We have just 13 years to deliver a net-zero electricity grid for the UK. The ammonia is stored, before being used for electricity generation. Source: CSIRO. million (US$1.8-million)

Power-to-gas trial to inject hydrogen into Australia’s gas grid; A$5M award to AquaHydrex

Green Car Congress

The Australian Renewable Energy Agency (ARENA) announced a trial for a new type of electrolyzer which could see excess renewable energy stored in the gas grid and used to decarbonize Australia’s gas supply. When hydrogen burns, it produces only water vapor and no carbon dioxide. —AGN CEO Ben Wilson.
