Couple of possibilities ...

1) ... I know this is the same AHS PR, but it is on the Velociti website and it indicates KANSAS CITY, Kan also ... It states:

Intelligent hydrogen systems to be installed on diesel combustion engines throughout North America

KANSAS CITY, Kan. & FARMINGTON, Ark. – July 10, 2012-

Deryk Powell is now the President and COO of Velociti ...

“The use of hydrogen systems to improve fuel economy in combustion engines has been on our radar for quite some time,” said Deryk Powell, COO of Velociti. “But frankly, until now, we’ve not felt a viable solution was available in the market. After many months of studying the engineering, manufacturing and design for AHS’s Hy-Impact product, we feel confident AHS offers enterprise-level users the solution they’ve been waiting for. The market potential for AHS is massive in size and we are pleased they understand the importance of professional deployment and trust Velociti to get the job done.”
