💡 The #LH2 complex is required for #lightharvesting in many bacteria. In a recently published study, Konstantin M. Boyko et al. reveal that a colorless #carotenoid fully substitutes for colored pigments while maintaining the octameric symmetry of the complex.

Here you have a cryoEM structure of the photosynthetic LH2-LH1 complex from the purple bacterium Halorhodospira halophila (PDB code: 8Z81)

‪Hey @canarymedia.com, if an 8MW liquid-hydrogen-fueled @plugpowerinc.bsky.social fuel cell can perform bumpless transfer from grid to islanded microgrid mode, it would be technical malpractice to not spend a few extra $ & program black-start capability! All the hardware is already there!

I could have saved SwRI’s client a lot of money by showing them this 1968 NASA report⬇️: solubility of hydrogen in liquified natural gas (methane) is well below 1% (≈0.06% v/v).

So it is basically impossible to store economically-useful amounts of #hydrogen in #LNG.
#H2 #LH2 #GH2 #methane #CH4

My issue is the lack of knowledge in some quarters...

As an @mitcheme.bsky.social with 40+ years of broad & deep knowledge of energy, I know that liquified natural gas #LNG systems cannot be easily repurposed to liquid hydrogen #LH2 use, etc.

It took me <5min of Googling to find that NASA report.

Gee whiz, I thought it was something better than cryo-compressed hydrogen #CCH2, not just liquid hydrogen #LH2...

Commercially-available processes:

#H2 via steam methane reforming #SMR natgas then liquifying the #GH2 with grid electricity to make #LH2

Grid electricity for liquid #O2 via (1) air separation #ASU then (2) liquifying the #GOX to make #LOX

Future renewable grids & #GreenHydrogen will be cleaner!

Thanks for applying science to spaceflight, but you totally left out the "upstream" CO2 emissions of making Blue Origin's liquid hydrogen and liquid oxygen:

The carbon intensity #CI of making #LH2 is ~12 kgCO2eq/kg H2;
#LOX is ~2 kgCO2eq/kg O2.

So today it's not very green! (Details below)
