Besides road vehicles, Ballard delivers fuel cells also for trains, mining trucks, marine applications, and backup power systems for critical infrastructures such as radio towers. Furthermore, a fuel cell system for application in is under development.
[pdf] In New Zealand:most residential homes would use a system between 1.5kW – 4kW. A panel-only no battery 4kWh system is around $10,000.a 3kW grid-connected solar power system is popular because it helps reduce electricity costs, while remaining relatively affordable (around $8,000).battery systems for a standard house cost around $10,000. .
