RE:RE:Temporary context regarding ValeYou are presuming that VALE continued the testing and is paying for it, ..time will tell
If Vale chose plasma which is powered by electricity which has consistantly increased in price and escalating and appears to cost 700 % more than gas the directors and all officers would have to resign.
Currently chinese steel plants are going bankrupt due to energy costs and electricity is the most expensive heat source by multiples. Infact china has placed surcharges on aluminum plants electrical use
Gas prices fluctuate and will decrease over time as demand decreases Take a look at 20 year gas prices, ( below) . Carbon offsets can be used to go full green and then they will go to hydrogen by 2050 or plant a few million more trees
Not to mention Vale partners with BHP on Pellet plants in Brazil and BHP is along with steel is a ..drum roll.. Gas Company
