Earlier quoted context omitted.
None of this applies to KSA's oil - which is more than enough oil to meet plastic consumption for 100 years. At $20 per barrel - the economics alone will be tough to beat with some other material.
Wow, I didn’t know that refining, shipping, and access to global capital didn’t apply to KSA. Such a magical country. They’re going to need that magic when the primary export collapses — or if it doesn’t, wet bulb temperatures in the Gulf make it literally unlivable. The $20 a barrel will be even harder to sustain in a protracted civil war, which is where they are headed if they don’t diversify enough.
KSA refines all its own oil.
KSA doesn't need capital. It's a money printing machine - even at $30 per barrel.
Shipping will have some impact. ~40% of global shipping cargo is fossil fuels.
However, my guess is, fossil fuel shipping would get even cheaper, not more expensive.
