Harry, the cost comparision is with the current technologies generate hydrogon.
(1) The minimum cost of a facility to generate commerical level hydrogen with electricity is $2 million. In addition to this fixed cost, on-going electricity usage adds variable cost with volume. As I posted in the IBOX, the cost of generating hydrogen from electricity is in the range of $4.00-5.00 per equivalent gallon of gasoline.
(2) We know Welch's facility is a commerical scale facility, we know the company didn't spend over $500K to construct it and generate hydrogen. The fixed cost is small compare to an electricity facility. We also know they use microbial to generate hydrogen instead of electricity. Microbial are free and cost nothing. Everything equal, one unknown cost we don't know is how they generate the heat treatment to keep the temperature at 90 degree for 20 minutes per cycle at the bioreactor. But I can bet the cost is much much less than using electricity.
(3) Remember they are generating hydrogen at a NON-LAB enviroment. Many posters here even doubt they could generate hydrogen at Welch. As they fine tune the system, I'd expect them to release more specific information on the volume content and others.
(4) They only suggested a possibility for the waste facility to generate additional income or alternative use of hydrogen.
As a matter of fact, coal was the fuel used to generate the largest share (50.8 percent) of electricity in 2005, natural gas was used to generate 16.7 percent, and petroleum accounted for 3.1 percent. If hydrogen is cheap and readily avaliable, isn't hydrogen can replace coal, natural gas, or oil to generate electricity?
Folks always find a reason to sell. If you look at the PRs and the price movement for the past several weeks, it has been always the case. When they hired Dr. Sergey Gazenko, folks posted they're running technical issues and hired an expert, sell! Today, it is no exception, guys always find a reason to sell.
For me and many of my friends, we are here for the long-term. We are not looking at the daily price movements or one PR, we look at the potentials in the long-term.
Contrary to some posters said, I believe today's news is not the end, I believe today is just a new start for NNLX, we'll hear many great news in the weeks or months to come.
