Distributed power generation that contributes to the reduction of CO2 emissions
What is Distributed Power Generation ?
Currently, the majority of electricity used by the general population is intensively generated by thermal power plants and nuclear power plants in remote areas.
Electricity is generated at thermal power plants by burning fossil fuels such as oil and coal, however, its energy efficiency is said to be approximately 35%.
In fact, 65% is emitted as a waste of heat and is lost when transmitted from the remote areas to the destination of its consumption.
Furthermore, nuclear power plants have serious security issues. Tokyo Electric Power Co., Inc., the largest electric power company in Japan, has the power generating capacity to accommodate the electricity demand, however, it has plunged into being unable to operate the power plants due to their inspections.
A possibility exists that these new power plants will become more and more difficult to build and to be profitable in terms of costs.
On the contrary, distributed power generation is built in the close proximity of electricity demand so that high thermal efficiency can be achieved and CO2 emissions can be minimized due to lesser electricity loss from transmission and the use of the heat from the power generation.
Power Generation with Fuel Cells
Power generation with fuel cells, which generates electricity through a reverse chemical reaction of water electrolysis, gives off cleaner emissions and is said to be an environmentally sound energy source.
The energy efficiency can be up to 80%, for the heat from the generation can be used on site as a heat source for air conditioners.
The figure above is a pattern diagram and actual fuel cell systems can be as compact as exterior units of home air conditioners.
Power Generation with Micro Gas Turbines (MGT).
Power generation with MGT can easily be installed by placing the equipment on site.
It can use various fuels such as a gaseous fuel and a liquid fuel. Its exhaust gas is substantially cleaner in comparison with other combustion engines.
Similar to fuel cell generation, it can generate electricity close to the destination of consumption so that high energy efficiency can be achieved by using heat waste for air conditioning.
It is expected to be used where the infrastructure for fuel supply is not yet developed and as peak-cut power generation.
