NTPC chooses Bloom Energy for supply of electrolyser



India’s largest power company, NTPC, has chosen Bloom Energy (India) Pvt Ltd., wholly owned subsidiary of California based Bloom Energy, for the supply of electrolysers.for the country’s first green hydrogen-based energy storage deployment.


The initial collaboration between NTPC and Bloom Energy India is expected to serve as a foundation for expanded future cooperation, says a press release from Bloom.

.

The collaboration will utilize Bloom Energy’s solid oxide, high temperature electrolyzer to generate green hydrogen from renewable electricity produced by a nearby floating solar farm. The hydrogen will then be converted into carbon neutral electricity without combustion through Bloom Energy’s hydrogen fuel cells to power NTPC’s Guest House, a local accommodation intended for use by NTPC employees and guests. The project is expected to commence in 2022 in Simhadri, Visakhapatnam, India.

The solar farm coupled with Bloom Energy’s electrolyzer and hydrogen fuel cells is intended to operate around the clock. At scale, the combination could enable long duration clean energy storage and resilient power for businesses, residential neighborhoods, dense urban areas, and remote and island communities.


The powerful combination of Bloom’s high-efficiency electrolyzers and fuel cells enables the highest possible round trip efficiency with green hydrogen for energy storage,” the release says.


The release says that Bloom Energy’s high-temperature electrolyzer produces hydrogen more efficiently than low-temperature PEM and alkaline electrolyzers. Because it operates at high temperatures, the Bloom Electrolyzer requires less energy to break up water molecules and produce hydrogen. Electricity accounts for nearly 80 percent of the cost of hydrogen from electrolysis. By using less electricity, hydrogen production becomes more economical and will accelerate adoption.

Bloom Energy Servers – solid oxide fuel cells that combine ambient air with a fuel source, such as natural gas, biogas, hydrogen, or a blend of fuels – produce electricity through a non-combustion electrochemical reaction, resulting in reduced carbon emissions, harmful air pollutants, and water use compared to grid alternatives. When hydrogen is used as a fuel source, Bloom Energy Servers emit zero carbon.
