Why turquoise hydrogen will Be a game changer for the energy transition

چکیده

With hydrogen being promoted as a promising energy vector for decarbonized world, low-carbon production methods are of interest to replace the current Steam-Methane-Reforming “grey” hydrogen. While existing studies focus on life-cycle-assessment green produced by water electrolysis, an alternative, which has attracted growing due much lower intensity (10–30 kWh/kgH2 < 50–60 kWh/kgH2), is turquoise pyrolysis methane. Specifically, this study conducts methane via thermal-plasma. A sensitivity analysis also conducted environmental-metric time-horizon and emissions rates. Results show that carbon-intensity using novel method 88.3–90.8% than grey Furthermore, renewable-natural-gas with feedstock percentage low 8–18% leads negative (reaching −4.09 −10.40 kgCO2e/kgH2 at 100% renewable natural gas), lowest compared grey, blue, hydrogen, making game-changer transition.

Will Real-Time Monitoring Technology be a Game Changer for Perfusion Safety?

I want to take this opportunity to thank the program committee for inviting me. I was asked specifically to discuss if real-time monitoring technology will be a game changer for perfusion safety. Again, there are no conflicts of interest for this presentation. To begin, the American Recovery and Reinvestment Act of 2009 stipulated that by January 1, 2014, all public and private health-care prov...

Editorial commentary: Disparities in invasive pneumococcal disease rates between populations: will the extended pneumococcal conjugate vaccines be a game-changer?

The first 7-valent pneumococcal conjugated vaccine (PCV7) was developed on the basis of data demonstrating that within the United States and other developed countries, the 7 vaccine serotypes were responsible for >80% of invasive pneumococcal disease (IPD) in young children [1]. Indeed, shortly after the introduction of PCV7, a significant and dramatic reduction in IPD rates was observed in man...
