BION has already negotiated long term deals for biomass supply and for the purchase of all urea produced. I don't remember the details and don't have time to look them up right now but at least for the next 10 years the cost of NG and biomass should not affect them.
Actually, it was for 25 years, according to a BION press release on March 3, 2014. (see their website)
A couple of things concern me about this statement. One, it was made by BK.
Two, I don't understand how the biomass seller, or the urea buyer, could enforce the contract if BION goes bankrupt.. Remember, this is a company that has never produced a pound of product.
And, how could BION enforce the contract if the biomass seller, or urea buyer, went bankrupt?
The "contracts", whose existence is inferred by BK, seem more aspirational than enforceable.
There is a reason, I think, people don't have 25-year firm contracts with national gasoline producers to provide all their gasoline for the next 25 years. The reason: such a contract would not make any sense.
