Bloom energy

  1. 1. History Dr. K.R. Sridhar, Bloom founder and Chief Executive Officer, in connection with creating a technology to convert atmospheric gases to oxygen for life support. Dr. Sridhar and his team built a fuel cell capable of producing air and fuel from electricity generated by a solar panel.
  2. 2.  In 2001, when their project ended, the team decided to continue their research and start a company. Originally called Ion America, Bloom Energy, was founded with the mission to make clean, reliable energy affordable for everyone on earth. In early 2006 Bloom shipped its first 5kW field trial unit to the University of Tennessee, Chattanooga. After two years of successful field trials in Tennessee , California, and Alaska, to validate the technology, the first commercial (100kW) products were shipped to Google in July 2008. eBay is reportedly using the100 Kilowatt boxes for powering 15 percent of its headquarters.

  4. 4. ENERGY SERVER It is built with patented solid oxide fuel cell technology. Blooms 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 different from hydrogen fuel cell in three
  5. 5. 1 . Low cost materials – This 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 technologies3. Fuel flexibility – This system are capable of using either renewable or fossil fuels
  6. 6.  Each Bloom Energy Server provides 200kW of power, enough to meet the needs of 160 average homes or an office building... day and night.
  7. 7. How a Solid Oxide Fuel Cell Works? 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
  8. 8.  A solid oxide fuel cell 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. The water gets recycled to produce the steam needed to reform the fuel. The process also
  9. 9.  As long as theres fuel, air, and heat, the process continues producing clean, reliable, affordable energy.
  10. 10. Energy Server Architecture Each Energy Server consists of thousands of Blooms 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“.
  11. 11.  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.
  12. 12. Benefits 1. Clean Energy: Bloom Energy delivers Better Electrons.  All electrons are not created equal. Only Bloom Energy delivers clean energy i.e electrons that are clean and reliable and affordable… 2 Reduce Energy Costs: Lower & Lock-In Energy Costs
  13. 13.  3 save money & environment ◦ Bloom allows you to save money first. The efficiency built into Blooms fuel cell systems allows a typical customer to achieve a 3-5 year financial payback making it an easy and economically sound choice. ◦ Customers can also reduce their CO2 emissions by 40%-100% compared to the U.S. grid ◦ References  www.bloomenergy.com www.google.com Digit Magazine
