Indonesia has some of the world's largest Ni laterite deposits- but cf with Ni sulphides,(which BSX has in its mines in Vietnam), Ni laterites are far "inferior", as they require much more energy to refine for EV vehicles & batteries.
The vast majority of Indonesia's energy comes from its vast coal (not as "clean", has high CO2 emissions, cf Australian coal), oil, & gas reserves.

BSX, of course, would use "clean green" hydro for its Ni mines, & proposed NCM refinery- MUCH more attractive for ESG purposes, & promoting the advantages/selection of EV vehicles etc.
Hopefully, VinFast would utilise BSX Ni mines & refinery for its EV vehicles & NCM batteries- gives it a strong PR advantage, on ESG grounds, compared to other vehicle makers who use fossil fuels.
