SAN JOSE, Calif., July 14, 2021 – Bloom Energy (NYSE: BE) today unveiled the Bloom Electrolyzer; the most energy-efficient electrolyzer to produce clean hydrogen to date and 15 to 45 percent more efficient than any other product on the market today.

The Bloom Electrolyzer relies on the same, commercially proven and proprietary solid oxide technology platform used by Bloom Energy Servers to provide on-site electricity at high fuel efficiency. Highly flexible, it offers unique advantages for deployment across a broad variety of hydrogen applications, using multiple energy sources including intermittent renewable energy and excess heat.

Superior Value at High Temperatures
Low-cost electrolysis has been difficult to achieve due to electricity costs, which can account for nearly 80 percent of the cost of hydrogen production through electrolysis. An opportunity has emerged, as renewable energy costs have declined precipitously over the last decade. Any reduction in electricity requirements makes hydrogen production more economical and scalable.

Because it operates at high temperatures, the Bloom Electrolyzer requires less energy to break up water molecules and produce hydrogen. As a result, Bloom Energy’s electrolyzer consumes 15 percent less electricity than other electrolyzer technologies to make hydrogen when electricity is the sole input source.

Unlike low-temperature PEM and alkaline electrolyzers that predominantly require electricity to make hydrogen, the Bloom Electrolyzer can leverage both electricity and heat to produce hydrogen. Bloom Energy’s high-temperature electrolyzer technology has the potential to use up to 45 percent less electricity when integrated with external heat sources than low-temperature PEM and alkaline electrolyzers.

“The launch of the Bloom Electrolyzer is a big leap forward in our mission to enable and empower the global hydrogen economy and a decarbonized society,” said KR Sridhar, founder, chairman, and CEO, Bloom Energy. “Hydrogen enables us to leverage abundant and inexpensive renewable energy to provide zero-carbon power, reliably—instead of intermittently. Given its efficiency and input options to make hydrogen, Bloom Energy’s electrolyzer is expected to produce hydrogen at a lower price than any alternative on the market today.”

Decarbonizing Heavy Industries
High-temperature electrolysis unlocks substantial value with heat-intensive processing applications in hard-to-decarbonize heavy industries, like steel, chemical, cement, and glass manufacturing. By utilizing excess heat from these processes, hydrogen can be produced at a higher electrical efficiency. Further, the hydrogen required to power high-temperature furnaces at these factories can be produced on-site using Bloom Energy electrolyzers, eliminating transportation and distribution costs.

Optimizing Intermittent Renewables
When the Bloom Electrolyzer is paired with intermittent renewable resources, such as wind and solar, the resulting green hydrogen provides an important storage mechanism. Hydrogen can be stored for long periods of time and transported over long distances. Alternatively, Bloom Energy’s fuel cells can convert this hydrogen to electricity, thereby providing continuous, reliable power.
