What is a fuel cell?

A fuel cell is a system that uses hydrogen taken out from city gas or LP gas and oxygen in the air, directly converts it to electricity through the reverse chemical reaction of electrolysis of water which generates electricity.
Since electricity is generated on the site where electricity is used, there is no electric transmission loss. Also, energy can be used efficiently since it utilizes the heat generated as a by-product of power generation, which has been discarded in the conventional power generation method, to heat water.
You can reduce CO2 emission while using the same amount of electricity and heat you have been using.
Furthermore, this is an environmentally-friendly power generating system with a low noise level and clean exhaust.

ECOWILL

What is a gas-engine water heater?

ECOWILL is the world's first home-use cogeneration system that uses a gas engine fueled with LP gas. It can provide [hot-water supply], [hot water (for heating)], and [electricity] in the house. ECOWILL generates heat with a gas engine, and efficiently utilizes exhaust heat, achieving 85% energy efficiency! This system covers most of the heat demands and approximately 40% of electricity demands at the average home, contributing to energy saving and cost reduction.

ENE-FARM
(Fuel cell for home-use)
ECOWILL
(Gas-engine water heater)
Mechanism
A fuel-cell type cogeneration system that takes out hydrogen from gas, and chemically causes reaction with oxygen in the air to generate electricity. Heat generated during power generation can be used to boil water, which is used for heating.
A gas cogeneration system for home-use that generates electricity with gas, and utilizes the by-product exhaust heat to boil water and use it for heating.
Types of energy to be created
Hot water, electricity, hot water (for heating)
Hot water, electricity, hot water (for heating)
Use efficiency from the primary energy
Approx. 70 to 80% (A)
Approx. 85% (B)
On-site power generation achieves high efficiency.
On-site power generation achieves high efficiency.
Advantages for customers
Reduction of total utility costs
Although use of gas will increase since power is generated using gas, the amount of electricity purchased will decrease, resulting in reduction of total utility costs.

The amount of electricity purchased will be reduced approximately 30 to 40% per year. (*A family of four in a house is assumed.)
Annual CO2 reduction
Approx. 30 to 40% (A)
Approx. 20% (B)
Electricity use during power failure
Not available
Not available
Operation noise
40dB (A)
as quiet as a library
(*subject to the influence of the installation environment)
44dB (B)
as quiet as a quiet residential area in the daytime
(*subject to the influence of the installation environment)
Main unit reference price
Approx. 3.5 million yen
Approx. 900,000 yen
Installation precautions
When installing in an existing house, installation space, piping, and wiring routes need to be secured. Also, construction for replacing the currently used components such as a panel board as well as application (for grid connection) to a power company are required. For details, contact our nearest sales office.

(A)
Comparison with thermal power generation system + conventional water heater. The values are based on the operating data (estimate) at an installation site of TOSHIBA FUEL CELL POWER SYSTEMS CORPORATION under the Large-Scale Stationary Fuel Cell Demonstration Project implemented by the New Energy Foundation. Furthermore, efficiency varies depending on the energy use and use pattern at each house.
(B)
Estimate by Honda Motor Co., Ltd.: Comparison was made against the case where electricity by thermal power generation and water heater fueled by gas are used.
