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. It took us a long time to get the data needed to let us connect to the grid. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%.

Wärtsilä to supply a major LNG/bioLNG production plant for CO2-neutral transport fuels

Green Car Congress

The plant will liquefy gas from the natural gas grid to produce carbon-neutral LNG. The use of LNG as an emissions-reducing fuel in the marine and transportation industries is already well established, and to introduce bioLNG which can be mixed with LNG is the next obvious step in enabling a CO2-neutral transportation fuel.

Montauk Renewables signs LOI with European Energy to provide CO2 for e-methanol production in Texas

Green Car Congress

Montauk Renewables captures methane, preventing it from being released into the atmosphere, and converts it into either RNG or electrical power for the electrical grid. The planned delivery would prevent biogenic CO 2 from entering the atmosphere and put it to beneficial use, creating a new fixed-price commodity revenue stream for Montauk.

EIA: California drought will decrease hydropower, increase natural gas use and CO2 emissions

Green Car Congress

California has a diverse electricity fuel mix and is highly interconnected with the regional electric grid, but our study shows that a significant decrease in hydropower generation this summer could lead to higher electricity prices, among other effects.

The world’s first CO2 battery for long-duration energy storage is being commercialized [update]

Electrek

Italian startup Energy Dome has now begun to commercialize the world’s first CO2 Battery, which was launched earlier this month in Sardinia, Italy. The battery uses carbon dioxide to store renewable energy on the grid, and Energy Dome says the technology can be quickly deployed anywhere in the world.
