3. ABSTRACT
 World has been constantly struggling with the
energy problems. Scientists are searching for new
economic, clean, renewable and efficient sources
of energy. Despite of all the expensive and
tremendous research, we are unable to find any
reliable energy resource which will satisfy all our
needs. Now the world has been introduced to
BloomEnergy, a new entry in the fuel cell business
which claims to be ready to revolutionize the
energy economy.

4. INTRODUCTION
 About 80 to 90 percent electricity used in world came
from non renewable fossil fuels
 Use of fossil fuels in electricity production release lot
os potentially harmful gases in air
 Fossil fuels are in limited quantity
 Sustainability is major problem of fossil fuels

5. WHAT IS
BLOOM BOX ?
Built solid oxide fuel
cell technology, Bloom's
Energy Server is a new class
of distributed power
generator, producing clean,
reliable, affordable
electricity at the customer
site.
The Bloom Energy Server
uses thin white ceramic
plates (100 × 100 mm) that
are made from components
found in beach sand

6. WHAT IS SOFC ?
 SOLID OXIDE FUEL CELLS (SOFC) are devices that
convert fuel into electricity through a clean electro-
chemical process rather than dirty combustion. They
are like batteries except that they always run

7. HOW SOFC WORK ?
 A fuel cell is like a battery that always runs. It consists
of three parts: an electrolyte, an anode, and a cathode.
 For a solid oxide fuel cell, the electrolyte is a solid
ceramic material. The anode and cathode are made
from special inks that coat the electrolyte. Unlike other
types of fuel cells, no precious metals, corrosive acids,
or molten materials are required.
 Next, an electrochemical reaction converts fuel and air
into energy, specifically electricity without
combustion.

9. WORKING
 A solid oxide fuel cell (SOFC) is a high temperature
fuel cell. At high temperature, warmed air enters the
cathode side of the fuel cell and steam mixes with fuel
to produce reformed fuel… which enters on the anode
side.
 Next, the chemical reaction begins in the fuel cell. As
the reformed fuel crosses the anode, it attracts oxygen
ions from the cathode. The oxygen ions combine with
the reformed fuel to produce electricity, water, and
small amounts of carbon dioxide.

11. A TIMELINE OF BLOOM ENERGY
 Located in sunnyvale california
 Founded in 2001
 Founded by Dr. KR Sridhar
 The device was originally invented to produce oxygen
on Mars but when NASA scrapped mars mission
Sridhar reversed his mars machine, pumping oxygen
instead of making oxygen

12. COST OF BLOOM ENERGY SEVER
 The current cost of bloom energy server of 100 kW
capacity cost $700000 to $800000 with 3 years of
recovery period
 Bloom box neccassary to run indian avg. Home will
cost $5000 with recovery period 5 to 6 years

13. ADVANTAGES OF BLOOM BOX
ENERGY
 Lower cost energy resourse
 Fuel flexible
 Sustainability
 Increased realiablity and sustainability
 Simple installation and maintainence

14. CO2 EMISSION

15. STRATEGIC IMPACT
 REDUCE THE ELECTRICITY COST

16. CURRENT CUSTOMERS
 Adobe
 Google
 Staples
 eBay
 Walmart

17. John donahoe eBay’s CEO says its five boxes
were installed over a Year ago and have already
saved the company $200000 in electricity costs

18. RISKS
 The technology is still in inception stage
 The cost of bloom box is not economical yet
 High operating temprature

19. TECHNICAL CONCLUSIONS
 When comparing fuel cells wind & solar power there
are several important factors to note
 First a bloom box still requires some sort of fuel to be
operated. This fuel is some kind of hydrocarbon so it
still add CO2 in atmosphere
 Second wind and solar power are not able to produce
constant level of electricity
 Lastly due to their variable nature wind & solar plant
of 100kw do not provide the same amount of power as
bloom box.
