Engine system
First Claim
1. An engine system, which comprises:
- first and second hydrogen supply devices for producing hydrogen rich gas from a medium which chemically repeats storage and release of hydrogen, and drives an engine by using hydrogen rich gas produced in the first and second hydrogen supply devices for fuel;
a waste heat supply device for supplying waste heat from the engine to the first and second hydrogen supply devices;
a generator which generates electricity by using power from the engine;
an energy storage device for storing electric power produced by the generator;
a motor for converting electric power supplied from the energy storage device into mechanical power; and
a combustor installed in an exhaust pipe of the engine, the combustor burning the hydrogen rich gas produced by the medium or the first hydrogen supply device,wherein the first hydrogen supply device is provided on the upstream side of the exhaust pipe with respect to a position where the combustor is installed, the second hydrogen supply device is provided on the downstream side of the exhaust pipe with respect to a position where the combustor is installed, and heat from the combustor is supplied to at least the second hydrogen supply device.

Abstract
An engine system includes a medium which chemically repeats storage and release of hydrogen to provide an engine system where CO2 emissions can be suppressed and system efficiency is excellent. The engine system includes a hydrogen supply device for producing hydrogen rich gas from a medium which chemically repeats the storage and release of hydrogen, and drives an engine using the hydrogen rich gas produced in the hydrogen supply device as one of the fuels. This engine system is characterized by comprising a waste heat supply device for supplying waste heat of the engine to hydrogen supply device, a generator which generates electricity by power of the engine, an energy storage device for storing electric power produced by the generator, and a motor for converting electric power discharged from the energy storage device into power.
