Green Hydrogen: Powering the Next Generation of Clean Energy Systems

By Mwikisa Kanguya

Hydrogen is becoming a key component of the worldwide clean energy transition because it provides a flexible, emission-free fuel that can decarbonize sectors like steel, long-duration energy storage, and heavy transportation where electrification is insufficient. Green hydrogen, when created with renewable energy, is a completely sustainable energy carrier that has the potential to replace fossil fuels on a large scale. For balancing intermittent renewable sources like solar and wind, its high energy density and portability make it perfect. Growing government backing, increased investment, and developments in electrolysis technology position hydrogen to be a key component of future low-carbon, resilient energy systems.

Production of Green Hydrogen

Green hydrogen is created by electrolysis, a technique that splits water (H₂O) into hydrogen (H₂) and oxygen (O₂) using electricity from renewable sources like sun, wind, or hydropower. Green hydrogen, when fueled by clean electricity, is completely carbon-free, in contrast to grey or blue hydrogen, which are dependent on fossil fuels and release carbon dioxide. Alkaline, PEM (Proton Exchange Membrane), and solid oxide electrolyzers are the three types of fundamental technology, and each has a unique cost and efficiency profile. This process’s scalability is largely dependent on having access to inexpensive renewable energy and water supplies. Green hydrogen is emerging as a sustainable fuel for energy storage, transportation, and industrial applications as innovation lowers the cost of electrolyzer systems and renewable energy sources, opening the door to a circular,

Green Hydrogen Disruptors: The Startups Reinventing Clean Energy

Electric Hydrogen

Electric Hydrogen is a U.S.-based startup co-founded by Raffi Garabedian that is advancing clean energy infrastructure through the development of high-power electrolyzer systems for large-scale hydrogen production. Its HYPRPlant platform features an advanced PEM stack capable of supporting gigawatt-scale output, designed to significantly reduce total installed costs and simplify on-site integration. Manufactured in the U.S., the system is optimized for rapid deployment and broad industrial use. Applications span key sectors including refineries, sustainable fuels, steelmaking, ammonia production, and chemical processing, helping enable the transition from fossil-based to hydrogen-driven operations.

Lhyfe

Co-founded by Marc D. Lhyfe is a French startup that specializes in the production and supply of green hydrogen generated exclusively from renewable energy and water, with no carbon emissions. Its decentralized model connects hydrogen production units directly to local renewable energy sources, enabling efficient on-site electrolysis and regional distribution. By integrating renewable power and water electrolysis, Lhyfe provides a sustainable alternative to fossil-based fuels for sectors such as transportation and industry. The company’s modular production solutions—onshore, on-site, and offshore—are designed to adapt to varying energy demands, advancing the energy transition through practical and scalable hydrogen infrastructure.

Hystar

Hystar is a startup co-founded by Magnus Thomassen that develops high-efficiency PEM electrolyzer technology for green hydrogen production, with systems engineered and manufactured in Høvik, Norway. Its core offering includes containerized 5 MW solutions and scalable non-containerized systems for large-scale projects.
