Mr.K.R.Sridhar, an Indian born Ph.D.

used to work for NASA to develop

technologies to sustain life on Mars. His

company, Bloom has been working for a

decade to produce the Bloom Boxwhich was officially launched on 24 FEB

2010.

WHO INTRODUCED THIS INNOVATIVE

IDEA ?

STRUGGLE FOR GREEN

About Bloom Energy:- (power plant in a box)

Bloom Energy is a provider of breakthrough solid oxide fuel

cell technology that generates clean, highly-efficient power

onsite from virtually any fuel source(from natural gas to a

wide range of biogases). Bloom Energys mission is to make

clean, reliable energy affordable for everyone in the world.

The Bloom Energy Server is currently producing power for

several Fortune 500 companies.

The company says that its first 100 kW Bloom Energy Servers were shipped

to Google in July 2008

What is an Energy Server?Built with our patented 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.

Each Bloom Energy Server provides 100kW of power.

There are similarities and differences between PEM and SOFC

technology

Proton Exchange Membrane (PEM)

Polymer electrolyte

Proton-conducting electrolyte

Low temperature (~100C)

Requires H2 fuel

CO is a poison Needs good reforming/separation

Precious-metal catalysts

Low thermal inertia

Fairly mature

SolidOxide Fuel Cell (SOFC)

Ceramic electrolyte

Oxygen-ion conductor

High temperature (~700C)

Can use hydrocarbon fuel

CO2 is not a poison May use reforming or CPOX

Inexpensive catalysts

Large thermal inertia

In development

Bloom allows you to save money first. The efficiency built into Bloom's fuel

cell systems allows a typical customer to achieve a 3-5 year financial

payback making it an easy and economically sound choice. But the

economics aren't the only story. Customers can also cut their

CO2 emissions by 40%-100% compared to the U.S. grid (depending on their

fuel choice) and virtually eliminate all SOx, NOx, and other harmful smog

forming particulate emissions.

More Benefits & Applications

Power for every individual house with less cost. Unlike Fuel cells they can withstand high temperature

Hydrogen Production and Non-polluting way of generation.

To save money, the Bloom Energy Server uses inexpensive

metal alloy plates for electric conductivity, where as in fuel cell

platinum is used for electric conductivity.

Closing thoughts:-

Let us hope this technology will be availableto ordinary customers with more efficiency

And reduced costs.

And also with the implementation ofBloom energy

we can make sure that our Environment will suffer less.Twenty percent of the Bloom Energy Server cost savings

depend upon avoiding transfer losses that result from

energy grid use.
