Aquaponics is a sustainable farming solution that’s a combination of hydroponics (growing plants in water) and aquaculture (raising fish in tanks). In the case of being hitched up to a Hyundai ix35 Fuel Cell, it operates by taking the water emitted from the fuel cell vehicle
and filtering this water into the fish tank. The aquaponics technology then harnesses minerals from the fish waste to grow the plants on the farm.
Support for this interesting display of fuel cell usage came from the London government, which has been a big backer of low carbon technologies.
