Hydrogenics (HYGS) is focused on two areas; Hydrogen Generation/Distribution and Hydrogen Fuel Cells. Their future looks really good because revenue generation is here now in applications like;

1. Hydrogen Generation and Fueling Stations
2. Solar and Wind hydrogen generation and storage
3. Materials Handling (Forklifts etc) to reduce emissions in warehouses.
4. Backup of Data Centers (partnered with Schneider Electric/APC)
5. Backup of Wireless Telecom stations (partnered with CommScope)
6. Small vehicle power (Deere, etc)

A great stock to invest in.
