Prisma Photonics vs Electric Hydrogen
Side-by-side comparison of AI visibility scores, market position, and capabilities
Prisma Photonics uses existing optical fiber cables as distributed sensors to monitor power grids, pipelines, and railways for physical disturbances and threats;
About
Prisma Photonics is an Israeli deep technology company founded in 2017 by Yotam Levy, Yoav Peled, and Ronen Dar, headquartered in Tel Aviv, Israel. The company commercializes distributed fiber optic sensing (DFOS) technology that converts existing optical fiber cables — deployed by telecommunications companies in power grids, pipelines, railways, and perimeter security — into continuous, distributed sensors. Rather than deploying discrete point sensors at specific locations, Prisma's technology uses the fiber cable itself as a sensing medium: laser pulses are sent along the fiber and backscattered light is analyzed to detect, locate, and classify physical disturbances (vibrations, strain, temperature changes) along the entire cable length with meter-level spatial resolution.
Electric Hydrogen designs and manufactures 100MW+ industrial electrolyzer systems for green hydrogen production at scale; raised $380M in funding including a $200M Series C in 2023;
About
Electric Hydrogen is a Natick, Massachusetts-based clean energy company founded in 2020 by Raffi Garabedian (former CEO of First Solar) and David Eaglesham. The company designs and manufactures large-scale industrial electrolyzers — systems that use electricity to split water into hydrogen and oxygen — intended to produce green hydrogen at the cost and scale required to decarbonize heavy industries. Electric Hydrogen's core product is a 100MW electrolyzer plant that represents one of the largest single electrolyzer systems commercially available, designed for industrial customers in steel, ammonia, chemicals, and fuel production who need hydrogen at massive volumes.
