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.

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.

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

Green Car Congress

Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. 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.

Fukushima Hydrogen Energy Research Field (FH2R) completed in Japan; aiming for low-cost green hydrogen production; P2G

Green Car Congress

Renewable energy output is subject to large fluctuations, so FH2R will adjust to supply and demand in the power grid in order to maximize utilization of this energy while establishing low-cost, Green hydrogen production technology. It has the capacity to produce, store, and supply up to 1,200 Nm 3 of hydrogen per hour (rated power operation).

Siemens Energy, FFI and GeoPura developing prototype ammonia cracker to produce hydrogen

Green Car Congress

We have just 13 years to deliver a net-zero electricity grid for the UK. It can be used for storing large amounts of hydrogen in a liquid form that builds on existing global supply chain infrastructure. The technology could then be scaled up for future markets, including industry, heat, and grid-scale power generation.
