Bloom Energy and Benefits

Bloom Energy

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. Fuel cells 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. 
Our particular type of fuel cell technology is different than legacy "hydrogen" fuel cells in three main ways:

1. Low cost materials – our cells use a common sand-like powder instead of precious
metals like platinum or corrosive materials like acids.
2. High electrical efficiency – we can convert fuel into electricity at nearly twice the
rate of some legacy technologies
3. Fuel flexibility – our systems are capable of using either renewable or fossil fuels
Each Bloom Energy Server provides 200kW of power, enough to meet the base load needs
of 160 average homes or an office building... day and night, in roughly the footprint of a
standard parking space. For more power simply add more energy servers.

Energy Server Architecture

At the heart of every Energy Server™ is Bloom's patented solid oxide fuel cell technology.
Each Energy Server consists of thousands of Bloom's fuel cells. Each cell is a flat solid
ceramic square made from a common sand-like "powder." Each Bloom Energy fuel cell is
capable of producing about 25W... enough to power a light bulb. For more power, the cells
are sandwiched, along with metal interconnect plates into a fuel cell "stack". A few stacks,
together about the size of a loaf of bread, is enough to power an average home. In an
Energy Server, multiple stacks are aggregated together into a "power module", and then
multiple power modules, along with a common fuel input and electrical output are
Aassembled as a complete system.
For more power, multiple Energy Server systems can be
In addition to Bloom's unmatched performance, this modular architecture offers...
· easy and fast deployment
· inherent redundancy for fault tolerance
· high availability (one power module can be serviced while all others continue to
· mobility

The Benefits of Bloom Energy
Bloom Energy is a Distributed Generation solution that is clean and reliable and affordable
all at the same time. Bloom's Energy Servers, assembled deployed side by side. can produce clean energy 24 hours per day,365 days per year, generating more electrons than intermittent solutions, and delivering
faster payback and greater environmental benefits for the customer. And while other DG systems may require lengthy installations, sunny locations, or demand for consistent 24/7/365 heat load, Bloom's systems are easy and fast to install, practically anywhere.
