A hydrogen gas generation system is provided for use in a mobile vehicle. The mobile vehicle may be for example, a car or truck or other vehicle such as a balloon, dirigible, airship, ship, or boat. The vehicle has an on-board hydrogen generator for generating hydrogen gas, preferably using an electrolysis process. The hydrogen produced by the electrolysis process is stored in an on-board hydrogen storage tank. Hydrogen from the storage tank is flowed into a vehicle propulsion system where the hydrogen gas is consumed to provide power to propel the vehicle. An on-board electrical generation system provides at least some of the electricity for the electrolysis process. In one example, the vehicle has an on-board electrical generator for providing electricity for the electrolysis process. The on-board electric generation system may be, for example, a solar photovoltaic cell system, a wind turbine generator system, or a regenerative braking generator, for example. Depending on the particular electrical generation process or processes used, the vehicle may generate hydrogen gas when moving, when coasting or braking, or when long-term parked.

Systems and methods are described for allocating frequency resources based on historical usage data in a wireless communication system. A base station tracks its local usage pattern to generate a set of historical usage statistics. The base station may share those statistics with another base station node in the same network and with a server. The server may generate a frequency resource allocation plan to allocate shared resources most efficiently to various base stations based on historical usage information. Allocating frequency resources in this manner reduces the probability of cochannel interference between nearby cells and optimizes power solutions for local and regional radio access networks.
