The fuel cell was purchased from Ballard Power Systems. The one-megawatt, hydrogen-powered fuel cell, also known as a proton exchange membrane fuel cell, can power 500 homes. Situated at a coal power plant in Eastlake, Ohio, the 54-foot PEM fuel cell is expected to handle peak loads from May through September.
Fuel cells don’t run out of power like batteries do. As long as a fuel source such as natural gas is supplied, hydrogen and oxygen can produce water and heat to power homes.
“This is a demonstration project. But if it works, it will be easy to scale up,” said FirstEnergy spokesperson Mark Durbin. The nine fuel cell system will be tested over the next five years, which is enough time to see how it performs in the real world
FirstEnergy’s proton exchange membrane (PEM) fuel cell is different from other cells, such as those produced by Bloom Energy.
The technology is different because Bloom Energy uses solid oxide fuel cells. This fuel cell is powered by more plentiful gas-based fuels, which helps cut costs.
Also, Bloom Energy’s $800,000 portable power plants, nicknamed Bloom Boxes, are only the size of industrial refrigerators. And it only takes a single 100 kilo-watt unit to power 100 homes or a 30,000 square-foot office building.
Another key difference is the temperature the fuel cells run at. Bloom Boxes operate at high temperatures, while PEM fuel cells run at room temperature. This makes the fuel cells more attractive in different markets. For instance, the automotive industry would prefer the PEM fuel cells over the other types.
Bloom Boxes are better suited to satisfy corporate needs rather than those of utilities. Bloom Energy recently sold its boxes to major companies like Google, eBay and Walmart.
