
100kW of power - 1MW or more
Baseload needs to 100 average homes or a small
office building
Day and night
Footprint – standard parking space
More energy – Add additional energy servers
BLOOM ENERGY SERVERS
Developed by a
Former NASA
Ames Researcher,
K.R. Sridhar
Each server is the
equivalent size of
one parking spot.
Cost Up to
$800,000 per unit
Ability to get off
the grid (but
should remained
connected to
ensure use during
emergencies)
Can sell excess
(unused) energy
back to power
company
Uses an
electrochemical
profess to generate
electricity,
operates at
extremely high
temperatures

FUEL CELL
TECHNOLOGY

Differs from legacy “hydrogen” fuel cells
 Use low cost materials – cells use a common sand
like power instead of precious metals like platinum
or corrosive materials like acids

High electrical efficiency – convert fuel into
electricity at nearly twice the rate of legacy
technologies

Fuel flexibility – systems are capable of using
either renewable or fossil fuels

Reversible – capable of both energy generation and
storage
