Jules Hydrogen™

An End-to-End Solution for Green Hydrogen Production

Jules Hydrogen is an end-to-end solution for clean hydrogen production, uniting a suite of technologies including Thermal Hydrogen Synthesis (THS), high-temperature thermal storage, advanced power electronics, BESS, and Photovoltaic-Thermal (PVT) panels into a single, efficient system that reduces costs and scales seamlessly from compact plants to large hydrogen hubs.

By capturing both solar heat and electricity, Jules Hydrogen harnesses up to four times more energy per acre, setting a new standard for zero-GHG hydrogen production. This approach enables affordable, scalable green hydrogen without costly infrastructure upgrades, accelerating the transition to a sustainable energy system that fosters harmony between environmental sustainability and global prosperity.

Thermal Hydrogen Synthesis (THS)

Utilizing Thermal Hydrogen Synthesis (THS)-a proprietary process that integrates thermal and solar energy-Jules Hydrogen enhances hydrogen production efficiency by up to 20%, optimizing performance in existing electrolyzer technologies such as PEM, alkaline, and SOEC. By leveraging advanced Photovoltaic-Thermal (PVT) technology, THS supplies both electrical and thermal energy to the hydrogen production process, reducing the energy demand on electrolyzers. This process captures and converts energy from PVT panels with maximum efficiency, delivering a consistent and cost-effective green hydrogen output.

THS is engineered to optimize heat transfer from end to end throughout the hydrogen production process, enhancing each phase to support ideal electrolyzer conditions. This full-spectrum approach minimizes energy usage, reduces wear, and extends the operational lifespan of electrolyzers. Scalable across various applications-from industrial facilities to dedicated hydrogen plants-THS represents a breakthrough in renewable hydrogen production, providing a technically advanced, environmentally sustainable, and economically viable solution that drives growth in the clean hydrogen economy.

Photovoltaic Thermal (PVT) Technology and THS

Photovoltaic-Thermal (PVT) technology enhances hydrogen production by capturing both solar electricity and thermal energy. Unlike standard PV systems, PVT panels generate electricity and capture heat simultaneously, providing a consistent thermal source that preheats water for electrolysis. This dual energy supply reduces the demand on electrolyzers-whether PEM, alkaline, or SOEC-improving their efficiency and lowering the total energy required for hydrogen production. By maximizing energy output per unit area, PVT technology in THS delivers a compact, cost-effective, and sustainable approach to green hydrogen, setting a new benchmark for renewable energy systems.

Advanced Dynamic Power Electronic Systems

Advanced DC power solutions are central to the scalability and adaptability of Jules Hydrogen. Technologies like IGBT-based buck rectifiers, SCR/thyristor rectifiers, and back-to-back DC/DC converters play a critical role in regulating and stabilizing power flows between renewable sources and the electrolyzer system. These power electronics ensure that Jules Hydrogen consistently delivers optimal voltage and current levels, regardless of fluctuations in renewable energy inputs. This stability enables Jules Hydrogen to operate efficiently across diverse production environments, from small modular units to expansive hydrogen hubs, ensuring reliable and scalable green hydrogen production.

Thermal Storage and Integrated Controls

Jules Hydrogen's efficiency is driven by a high-temperature thermal storage system that captures surplus heat from PVT panels, pre-heating water feedstock to reduce the electricity needed for hydrogen production. By lowering the demand on electrolyzers, this storage system cuts operational costs, stabilizes production, and boosts energy conversion efficiency. An advanced control system seamlessly integrates thermal storage, PVT panels, power electronics, and electrolyzers, continuously adjusting energy flows to optimize output. This dynamic balance between thermal and electrical inputs ensures Jules Hydrogen operates at peak efficiency, maintaining stable production even with renewable energy fluctuations.

"I believe that water will one day be employed as fuel, that hydrogen and oxygen which constitute it, used singly or together, will furnish an inexhaustible source of heat and light."
Jules Verne, "The Mysterious Island"

Jules Hydrogen takes its name from Jules Verne, the pioneering author who, in The Mysterious Island, envisioned a world powered by hydrogen. This homage captures Jules Hydrogen's commitment to making Verne's vision a reality.  By transforming hydrogen into an affordable, scalable, and zero-emissions energy source, Jules Hydrogen aims to fulfill Verne's dream of an inexhaustible, sustainable energy future.

Hydrogen production and carbon emissions

the case for green hydrogen

Hydrogen production is currently dominated by carbon-intensive methods, primarily steam methane reforming (SMR). SMR is a process in which natural gas (mainly methane) is heated with steam to produce hydrogen. While widely used due to its relative efficiency and lower cost, SMR is heavily reliant on fossil fuels, emitting substantial quantities of carbon dioxide (CO₂) as a byproduct.

For every kilogram of hydrogen produced through SMR, approximately 9-10 kilograms of CO₂ are released into the atmosphere. Given that most hydrogen production globally still relies on SMR, this makes hydrogen a significant contributor to greenhouse gas (GHG) emissions.This reliance on high-emission processes for hydrogen production presents a critical challenge, particularly as the world seeks to scale up hydrogen use in sectors such as transportation, industry, and power generation for a cleaner energy transition.

Without a shift to low-carbon or zero-carbon production methods, such as electrolysis powered by renewable energy, hydrogen's potential as a clean energy carrier cannot be fully realized. As a result, there is growing interest in alternative methods like green hydrogen production through electrolysis and innovative solutions like Thermal Hydrogen Synthesis (THS), which combine renewable energy sources to produce hydrogen without emitting CO₂.Transitioning from traditional SMR to renewable hydrogen technologies can play a crucial role in reducing the carbon footprint of hydrogen and aligning its production with climate goals.
