World's First "Ene-Farm" Home Fuel Cell for Condominiums to Be R

World's First "Ene-Farm" Home Fuel Cell for Condominiums to Be Released 
Tokyo, Oct 21, 2013 - (JCN Newswire) -  Tokyo Gas Co., Ltd. (President:
Tsuyoshi Okamoto, hereafter "Tokyo Gas") and Panasonic Corporation
(President: Kazuhiro Tsuga, hereafter "Panasonic") today announced
the joint development of the world's first "Ene-Farm" home fuel
cell for condominiums(1)(2). The new "Ene-Farm" home fuel cell for
condominiums will be sold by Tokyo Gas from April 1, 2014. The product is the
first commercialized fuel cell in the world(3) where the fuel cell unit, hot
water unit and backup heat source unit can all be stored in the pipe shaft(4)
of the condominium. 
In comparison to detached houses, condominiums have more restrictions on the
conditions for installations. By increasing the airtightness of the unit
itself, it has become possible to install the new fuel cell in the pipe shaft
in the open hallway(5) of a condominium. In addition, in order to meet the
installation standards of condominiums, the legs that anchor the unit have been
strengthened, making the fuel cell more earthquake resistant, and measures,
such as a modified exhaust structure, have improved the wind resistance of the
fuel cell, making installation in the upper floors of a condominium and
operation in strong winds possible. 
Compared to using electricity from thermal power plants and heating water
using city gas(6), the new "Ene-Farm" fuel cell for condominiums
reduces primary energy consumption by approximately 37 percent and CO2
emissions by approximately 49 percent(7) when operating at the rated
electricity generation. In a model case, users can cut around 30,000 to 40,000
yen from their annual utility bills, and reduce annual CO2 emissions by
approximately 1.0 ton(8). 
Tokyo Gas is aiming for sales of 500 units in FY 2015 (ending March 31, 2015). 
In last fiscal year, Tokyo Gas expressed its intention to announce the release
of the new fuel cell for condominiums in FY 2014 (ending March 31, 2014). As of
Monday October 21, Tokyu Land Corporation and Sohgoh Real Estate have expressed
their will to adopt the new fuel cell in condominiums they will sell (2
properties, 456 units)(9). 
Through the spread of these "Ene-Farm" products, Tokyo Gas and
Panasonic will contribute to bringing greater comfort to their customers'
lives as well as helping to protect the global environment and cutting peak
power demand. 
(1)Development was partially based on results obtained from a project
commissioned by the New Energy and Industrial Technology Development
Organization (NEDO). 
(2) The hot water unit of Ene-Farm and the backup heat source to heat up hot
water for home heating and to supply hot water in case no hot water is left in
the hot water tank were developed jointly by Tokyo Gas, Gaster Co., Ltd. and
Rinnai Corporation. 
(3) There have been cases where Ene-Farms for detached homes have been
individually modified to comply with standards for installation in
condominiums. In such cases, Ene-Farms were installed outside the pipe shaft
(in the alcove in front of the entrance). However, the new fuel cell for
condominiums has a standard specification that complies with standards for
installation in condominiums. The fuel cell unit, hot water unit and backup
heat source can all be installed within the pipe shaft. 
(4) A pipe shaft is a space to store water and gas pipes that runs vertically
through condominium floors. The pipe shaft is usually located beside the
entrance in many condominiums. 
(5) An open hallway refers to a hallway having residential units on one side,
with the other side facing exterior space. 
(6) This is a method whereby electricity is supplied by thermal power plants
and heat is generated using city gas supplied by Tokyo Gas. 
(7) Compared to the method with a rated electricity generation operation of
0.75 kWh and heat recovery volume of 1.08 kWh / approximately 37 liters at 40
degrees Celsius. 
(8) Conditions used for estimate:
 (1) Primary energy equivalent - Electricity: 9.76 MJ/kWh (Act on Rational Use
of Energy), gas: 45 MJ/cubic meter (Tokyo Gas data), heating efficiency: 80
 (2) CO2 equivalent - Electricity: 0.69 kg-CO2/kWh (Interim Report of Goal
Achievement Scenario Subcommittee, Global Environment Committee, Central
Environment Council, July 2001), gas: 2.29 kg-CO2/cubic meter (Tokyo Gas data)
 (3) Annual burden - Hot water supply: 13.01 GJ, warming bath water: 1.45 GJ,
cooking: 1.8 GJ, air conditioning (cooling): 4.15 GJ, floor heating: 7.75 GJ,
air conditioning (heating): 2.77 GJ, lighting and others: 11.41 GJ (3-person
family in a condominium unit (total floor area: 80 square meter))
 (4) Power demand/power consumption for homes using gas and electricity: 3,643
kWh (Tokyo Gas survey)
 (5) Gas charges - conventional system: using "Danran Plan";
Ene-Farm: using "Eco plan with Ene-Farm". Electricity charges-using
"Meter Rate Lighting B" with 40 A contract for both conventional
system and Ene-Farm. Gas-electricity charges: estimates calculated based on
adjusted unit charges as of January 2013. 
(9):Properties intending to adopt the Product:
 Sohgoh Real Estate (Property name: (Provisional Title) RENAI SKY PREMIER
SHINAGAWA-NAKANOBU: Planned number of units: 100; location: 6 Nishioi,
Shinagawa-ku, Tokyo; planned release date: February 2014)
 Tokyu Land Corporation (Property name: Branz City Shinagawa Katsushima:
Planned number of units: 356; location: 1 Katsushima, Shinagawa-ku, Tokyo;
planned release date: April 2014) 
Main Features 
(1) Installation possible in pipe shafts
 Through measures such improvements in the airtightness of the unit itself and
thickened exterior panels, the installation of the fuel cell unit, hot water
unit and backup heat source in the pipe shaft in an open hallway has become
possible. In addition, the exhaust etc. for the fuel cell unit has been
integrated into a single outlet, making installation within the pipe shaft
possible, and creating a sense of uniformity when it is installed close to the
backup heat source. 
(2) Compliance with standards for condominium installation
 In order to comply with condominium installation standards, the legs to
anchor the main body have been strengthened to improve earthquake resistance.
Changes in the structure integrating the intake and exhaust outlet etc. of the
fuel cell unit and have reduced the impact of wind pressure to the equipment
interior, allowing operation during strong winds of 30 m/s and enabling
installation in the upper floors of a condominium. 
(3) Compatible with various installation conditions
 In addition to installing the fuel cell unit, hot water unit and backup heat
source all together in a pipe shaft, it is also possible to install them
separately in more than one pipe shaft. By offering multiple exhaust methods
for the fuel cell unit and backup heat source and by offering a backup heat
source that is slimmer than the standard model, the fuel cell can be installed
in various configurations in condominiums.
