Abstract: A microscale energy cogeneration system includes at least a micro/nano-turbine set for converting fuel into mechanical energy, and a generator for converting mechanical energy produced by said micro/nano-turbine into electrical energy in the range of 1 to 5 kWh. The system further includes an exhaust passage downstream from said micro/nano-turbine delivering high temperature exhaust air from said micro/nano-turbine. At least one heat exchanger receives high temperature exhaust air from said exhaust passage for heat transfer. Said heat exchanger may be used to heat water and/or air of a house. A water heating system may be coupled to the heat exchanger for convening tap water into hot water and/or cool heating air into hot air. The portable micro/nano-turbine set may be scaled up by interconnecting several units at the same time and/or interconnecting different units of different users for balancing out the energy demand of those users.

Abstract: A modular compressed natural gas station, including a modular compact unit with a flat supporting surface, lateral walls and a detachable roof. At least two different areas are defined inside the modular compact unit: a first anti-explosive area where a set of gas storage vessels and a compressor unit are lodged and a second area where an engine for driving said compressor unit and a measuring bridge unit are arranged. The station is capable of being transported and includes connectors for receiving gas from the general gas pipeline and connector for gas dispenser units. The second area also includes a measuring bridge unit for controlling variables of the station and an electrical switching board.
