Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. of hydrogen is currently produced via water electrolysis and only a fraction of this production is powered by renewable energy.

Study finds GWP of electrolyzed hydrogen to meet ORD’s fuel needs would be 2.5x that of fossil fuels with 2020 grid mix

Green Car Congress

Phil Ansell, an aerospace engineer at the University of Illinois Urbana-Champaign, modeled the life cycle carbon dioxide equivalent emissions of liquid hydrogen production required to meet the fuel needs of Chicago’s O’Hare International Airport (ORD) with today’s electric grid mix.

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.

Tesla submerges Powerwall 3 in water amidst larger advertising efforts

Teslarati

In a brief advertisement video shared on YouTube earlier this month, Tesla showed a demonstration of the recently released Powerwall 3 submerged in water and still powering appliances, noting that it can continue to operate in more than two feet of water. The Powerwall 3 offers an energy capacity of 13.5 kWh and 11.5

Sandia team develops GaN diode that is significant step toward protecting grid from EMPs

Green Car Congress

Scientists from Sandia National Laboratories have developed a new gallium-nitride (GaN) diode that can shunt excess electricity within a few billionths of a second while operating at a record-breaking 6,400 volts—a significant step towards protecting the nation’s electric grid from an electromagnetic pulse (EMP). —Bob Kaplar.
