Hydrogen on demand has taken over my small construction company. Pricing for our kits is available from the online shop and we are located in Edmonton, Alberta, Canada. Click the 3 lined waffle to get to the online shop for price by model that matches the engine size in litres. If you're Albertan I offer free delivery and install with a 5% discount
