In farm sector the hydrogen distribution is not a problem because hydrogen can be produced on site using the available renewable energies wind photovoltaic biomass. The main activities are - Development of a hydrogen production and storage system based on 1 photovoltaic and electrolyzer fig. 14 2 biomass 3 low temperature thermolysis 4 high temperature pyrolysis - Design and development of tractor equipped with fuel cell powertrain on board hydrogen storage system and other needed auxiliary subsystems. - Development of energy saving systems for efficiency increase. Some of these are photovoltaic roof high efficiency air-conditioning and external lights hydraulic systems and power take-off PTO with electric drive. - Replacement of hydraulic drive with electric drive avoiding oil that is a polluting substances and increasing the check. - Design of a Multi-Power Testing-Trailer able to carry out simultaneous tests on the traction hydraulic system and electric devices. - Field test of the FC tractor during operation both in external sites and inside places hayloft . Fig. 20. Hy-Tractor Project layout with photovoltaic plant. The H-BUS is a joint project of National research Council of Italy and two supplier companies to develop a range extender Fuel Cell Battery Hybrid Electric city bus. The aim of H-BUS project is to realize a pre-commercial Fuel Cell Battery HEV able to increase the range at least 30 with respect to same bus in a standard electric configuration using a small size of fuel cell that works as batteries recharge on board. Within the project CNR TAE Institute is involved in determining the optimal level of hybridization assessing all boundary conditions mission performances hydrogen consumption range etc. . The bus selected for the prototype realization is an .
