Key strategic elements OBSTACLE STRATEGY 

1.      Current incumbent (diesel 

engine) has immense capital 

asset advantage; significant 

market presence  

•

Use excess capacity in the existing value chain to 

deliver new product

•

Enter narrow market segments with catalyst for 

change 

2.      New refueling infrastructure 

required 

•

Focus on high‐fuel‐use fleets to maximize capital 

efficiency and lower risk. 

•

Create fueling alliances with natural gas industry. 

3.      Purchase price premium to  

incumbent technology 

(diesel)

•

Deliver lower overall lifecycle costs with 

competitive reliability, lower fuel costs, emissions 

credits

4.      Initial success will require 

rapid scaleup

•

Focus on OEM supply chain to enable rapid scale‐

up without supply chain disruption or heavy 

capital investment.
