Lower & Lock-In Energy Costs


Take Control of your Energy Economics
Depending solely on your local utility for your power needs leaves you exposed to significant risk. Prices are increasing and volatile and outages are unpredictable, leaving you vulnerable to damages from brownouts, surges, and unexpected service interruptions.
Lack of consistent service isn't the only consideration, because if history means anything, electricity prices aren't likely to go down. In fact, in places like California, they've gone up on average ~6% per year over the last 40 years. And while no one knows for sure what the future holds for grid electricity prices, most experts conclude that they will continue to increase significantly over the next decade due to a combination of rising fuel costs, pending carbon legislation, and large investments required to overhaul the antiquated grid infrastructure to keep pace with our modern world.
For those uncomfortable with this status quo, Bloom Energy can help you take control of your energy economics.
Lower Costs
Bloom Energy enables you to save money by lowering your electricity costs. Our customers today generate their own electricity for less than they pay their power company. The savings typically provide a 3-5 year payback on their initial capital investment.
Our systems can generate electricity cheaper than the power company for two main reasons. First, Bloom's unmatched efficiency in converting fuel to electricity means that our systems produce significantly more electricity for the same fuel costs. Second, our ability to generate the electricity on-site eliminates the need for costly transmission and distribution infrastructure.
Lock-in Pricing
While lowering energy costs is important, for some it is even more critical to make them predictable. Bloom Energy offers you a way to lock-in your electricity costs for the long term. You can fix your electricity costs by entering into a long term fuel contract with your gas supplier and taking advantage of our ability to consistently produce clean electricity from that fuel.
Pay As You Grow
Bloom Energy provides a modular solution that allows you to incrementally increase your onsite generating capacity if, and when, your energy needs grow. Instead of being forced to anticipate your power demand for the next ten to twenty years and paying upfront for equipment capacity you can't use, our solution allows you to match your initial deployment to your current base load and to pay as you grow.
...AND IT'S CLEANER TOO
Bloom Energy doesn't believe that achieving your sustainability goals should cost you more. Given the opportunity to save money and help the environment, the right decision becomes an easy one.

Solid Oxide Fuel Cells


Fuel cells were invented over a century ago and have been used in practically every NASA mission since the 1960's, but until now, they have not gained widespread adoption because of their inherently high costs.
Legacy fuel cell technologies like proton exchange membranes (PEMs), phosphoric acid fuel cells (PAFCs), and molten carbonate fuel cells (MCFCs), have all required expensive precious metals, corrosive acids, or hard to contain molten materials. Combined with performance that has been only marginally better than alternatives, they have not been able to deliver a strong enough economic value proposition to overcome the status quo.
Some makers of legacy fuel cell technologies have tried to overcome these limitations by offering combined heat and power (CHP) schemes to take advantage of their wasted heat. While CHP does improve the economic value proposition, it only really does so in environments with exactly the right ratios of heat and power requirements on a 24/7/365 basis. Everywhere else the cost, complexity, and customization of CHP tends to outweigh the benefits.
For decades, experts have agreed that solid oxide fuel cells (SOFCs) hold the greatest potential of any fuel cell technology. With low cost ceramic materials, and extremely high electrical efficiencies, SOFCs can deliver attractive economics without relying on CHP. But until now, there were significant technical challenges inhibiting the commercialization of this promising new technology. SOFCs operate at extremely high temperature (typically above 800°C). This high temperature gives them extremely high electrical efficiencies, and fuel flexibility, both of which contribute to better economics, but it also creates engineering challenges.
Bloom has solved these engineering challenges. With breakthroughs in materials science, and revolutionary new design, Bloom's SOFC technology is a cost effective, all-electric solution.
Over a century in the making, fuel cells are finally clean, reliable, and most importantly, affordable.

Energy Server Architecture

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 assembled as a complete system.


For more power, multiple Energy Server systems can be deployed side by side.
In addition to Bloom's unmatched performance, this modular architecture offers...

  • easy and fast deployment
  • inherent redundancy for fault tolerance
  • high availability (one power

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 four 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
  4. Reversible – our technology is capable of both energy generation and storage
Each Bloom Energy Server provides 100kW of power, enough to meet the baseload needs of 100 average homes or a small office building... day and night, in roughly the footprint of a standard parking space. For more power simply add more energy servers.

Bloom Box Energy & Walmart

Bloom Box Energy & Walmart

Walmart views sustainability as an important opportunity for both the future of their business and
the world. Accordingly, they have set a vision of supplying their operations with 100% renewable
energy. Walmart, which evaluates their energy vendors with the same rigor they apply to all their
suppliers, sought a renewable energy solution that could contribute to their sustainability goals
and help lower costs for the business and its customers. Walmart has completed Energy Server
deployments with 400kW systems at two southern California retail locations.
“At Walmart, our goal is to be supplied by 100 percent renewable energy. To do this, we are
considering a number of emerging technologies, including Bloom Energy, to ensure they work for
our business, help lower costs for our customers, and reduce our impact on the environment. We
hope to use our scale to help bring these technologies to market in a fast and cost effective way,”
said Bill Simon, Chief Operating Officer, Walmart U.S.
