NOVELTY - The system has an elevated structure e.g. bridge (48), and an electrolysis device e.g. Hoffman apparatus, for production of gaseous products such as hydrogen and oxygen, from water. A conduction device transfers electrical output of an energy generating subsystem to the electrolysis device or to an electrical power storage device e.g. battery. The conduction device includes a switching device for shunting the output to the electrolysis device or to the electrical device. A multi-service station network generates electrical power using the products and dispenses the products based on demand.    USE - Site system for provision of electrical and fuel products e.g. gasoline and either compressed natural gas (CNG) or liquefied natural gas (LNG), for site servicing of a marine craft e.g. pleasure power boat, or clean air vehicle (CAV) such as hybrid vehicle, low emission vehicle (LEV) and zero emission vehicle (ZEV), in a road way and an industrial site (all claimed). Can also be used for waterways, commercial sites, dwellings, savannas, buildings, open spaces, public areas, parks, rivers, lakes, oceans, and airspace.    ADVANTAGE - The system is physically compact and essentially fixed, and contemporaneously provides electrical and fuel products for immediate site-servicing of the eco-friendly vehicles. The system combines the elements such as electrolysis device, at sites, thus providing maximum operational efficiency and accessibility for the vehicles.    DETAILED DESCRIPTION - The energy generating subsystem is selected from a group consisting of a solar panel (12), a wind power generator (14), a tidal barge (16), and a water power generator. The conduction device includes a capacitor made of electrolytes, metal oxide coated electrodes, carbon nanotubes and conductive polymers, organic electrolytes and carbon aerogel, and selected from the group consisting of a supercapacitor, an ultracapacitor and a double-layer capacitor. The multi-service station network comprises service modalities selected from the group consisting of a fuel cell charging station, a methane mixer-low emissions vehicle charging station and a zero emissions vehicle charging station.
