Title: Energy management system
Inventor: ITO MASANORI
IPC: H02J3/00
Filed: 2019-03-27
Abstract: To provide an energy management system that mainly performs energy conversion between power and hydrogen.SOLUTION: A system platform 1 performs daily power demand prediction, and transmits a power generation instruction that enables necessary demand power to be ensured to each power generation facility. Surplus power is sent to a hydrogen station 3, and converted into hydrogen by an electrolytic and power generation device 4 arranged in the hydrogen station 3. Hydrogen produced in the hydrogen station is added to intake air of an engine for improving the combustion efficiency. That is, in a case where a load of the engine largely fluctuates in a marine vessel or vehicle, the amount of fuel supplied into a cylinder of the engine changes. Particularly when the amount of fuel increases abruptly, incomplete combustion occurs, and CO and the like are produced, but if a slight amount of hydrogen is added to the intake air, a hydrogen gas is burnt first in the cylinder because the combustion speed of the hydrogen gas is extremely higher than that of gasoline or heavy oil. Through this combustion, the fuel in the cylinder is made fine on the molecular level, and mixed into the intake air, so that complete combustion is promoted.SELECTED DRAWING: Figure 1
