Hydrogen Blending and Long‑Duration Clean Energy Storage Demonstration at Caltech

Fuel cell technology

The Bloom Energy Server is a stationary, modular power generation system based on solid oxide fuel cell (SOFC) stacks that converts chemical energy from fuels such as natural gas, biogas, or hydrogen directly into electricity through an electrochemical process, without combustion, to provide always‑on, highly efficient power for commercial and industrial customers.[6][8]

The Bloom Electrolyzer is a high‑temperature solid oxide electrolyzer cell (SOEC) system designed to produce hydrogen by splitting steam into hydrogen and oxygen using electricity, delivering higher hydrogen output per megawatt than conventional low‑temperature PEM or alkaline electrolyzers and targeting large‑scale clean hydrogen applications.[9]

A collaborative project between SoCalGas and Bloom Energy to generate hydrogen and blend it into the existing natural gas network at the California Institute of Technology in Pasadena, intended to showcase how hydrogen can be integrated into gas infrastructure for decarbonization and resilience.

A high‑temperature solid oxide electrolyzer installation at NASA’s Ames Research Center in Mountain View, California, which Bloom Energy describes as the world’s largest solid oxide electrolyzer and uses to demonstrate high‑efficiency hydrogen production.

A solid oxide electrolyzer cell (SOEC) system that generates green hydrogen from renewable power. The technology is manufactured in Delaware and California and is positioned as efficient, reliable, proven, and low-cost.

A system that uses solid oxide fuel cells to generate power from hydrogen without combustion, aiming to reduce carbon emissions and increase reliability.
