Bloom Energy has unveiled its new “Bloom Electrolyser” today (July 14) that is said to be the most energy-efficient electrolyser to produce clean hydrogen to date with 15 to 45% more efficiency than other products on the market today.
The new electrolyser 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.
In being 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.
The Bloom electrolyser operates at high temperatures meaning that it requires less energy to break up water molecules and produce hydrogen.
As a result, Bloom Energy’s electrolyser consumes 15% less electricity than other electrolyser technologies to make hydrogen when electricity is the sole input source.
Unlike low-temperature PEM and alkaline electrolysers that predominantly require electricity to make hydrogen, the Bloom Electrolyser can leverage both electricity and heat to produce hydrogen.
Bloom Energy’s high-temperature electrolyser technology has the potential to use up to 45% less electricity when integrated with external heat sources than low-temperature PEM and alkaline electrolysers.
When the Bloom Electrolyser 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.
KR Sridhar, founder, Chairman, and CEO of Bloom Energy, said, “The launch of the Bloom Electrolyser is a big leap forward in our mission to enable and empower the global hydrogen economy and a decarbonised society.
“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 electrolyser is expected to produce hydrogen at a lower price than any alternative on the market today.”
