Here we present the successful scaling of a thermally integrated photoelectrochemical device—utilizing concentrated solar irradiation—to a kW-scale pilot plant capable of co-generation of hydrogen .
Solar hydrogen production devices have demonstrated promising performance at the lab scale, but there are few large-scale on-sun demonstrations. Here the authors present a thermally integrated kilowatt-scale pilot plant, tested under real-world conditions, for the co-generation of hydrogen and heat.
CORALVILLE, IA – October 21, 2024 – SunHydrogen, Inc. (OTCQB: HYSR), the developer of a breakthrough technology to produce renewable hydrogen using sunlight and water, today shared an update on the Company's progress toward demonstrating its green hydrogen panels at the commercially-relevant 1m² scale.
Notably, a two order-of-magnitude increase in solar hydrogen production power (HHV) is achieved when compared with previous results: 32 W (ref. 3) vs >2.0 kW achieved in this work (averaged over total experimental time).
As outlined in Supplementary Table 3, the maximal peak hydrogen production rate calculated over a 5 minute window was 14.0 Nl min −1 (1.26 g min −1), and during the complete campaign, more than 3.2 kg of solar hydrogen was produced. The system produces on average 10.6 kW th of thermal heat at an outlet temperature of 45.1 °C, as defined in Methods.
At an output level of about half a kilogram of solar hydrogen per day, the EPFL campus system could power around 1.5 hydrogen fuel cell vehicles driving an average annual distance; or meet up to half the electricity demand and more than half of the annual heat demand of a typical four-person Swiss household.
The solar to hydrogen (STH) efficiency of photovoltaic-electrolysis (PV-E) setups is a key parameter to lower the cost of green hydrogen produced. Commercial c-Si solar cells have neared saturation with respect to their efficiency, which warrants the need to look at alternative technologies.

Hydrogen storage and batteries are two prominent technologies for energy storage, each with its own advantages and limitations. Here is a detailed comparison between the two [7, 21]: Energy Density: Batteries generally have higher energy density compared to hydrogen storage systems.
Batteries' Levelized Cost Of Storage could be 10 times higher than hydrogen. The energy transition is pushing towards a considerable diffusion of local energy communities based on renewable energy systems and coupled with energy storage systems or energy vectors to provide independence from fossil fuels and limit carbon emissions.
The efficiency of batteries and hydrogen systems can vary depending on various factors and specific technologies used. The efficiency of batteries typically ranges from 80 to 95%, while the efficiency of hydrogen systems can vary depending on the method of hydrogen production, storage, and utilization.
On the other hand, even though the hydrogen storage system can be considered a single energy storage solution, it has been divided into two conversion systems (e.g., electrolyser and fuel cell) plus one storage (e.g., hydrogen tank) to evaluate the power and energy decoupling nature of this solution.
Hydrogen storage is a compelling motivation in the realm of energy storage due to its unique advantages and potential. As an emerging storage technology, hydrogen offers a flexible and scalable solution for storing renewable energy over extended periods, addressing the intermittency challenge of renewable sources .
Power Density: Hydrogen storage systems typically have higher power density than batteries. This means that hydrogen can be quickly converted into electricity at high power levels, making it suitable for applications that require rapid energy release, such as fuel cells in vehicles.

H = (C x O x G x A) ÷ R 100 (H) = Volume of hydrogen produced during recharge. (C) = Number of cells in battery. (O) = Percentage of overcharge assumed during a recharge, use 20%.
During the recharge process, a lead acid battery releases hydrogen and oxygen through the electrolysis of sulfuric acid. The beginning of gassing is determined by the battery voltage. The amount of gas released depends on the current that is utilized in the electrolysis of the sulfuric acid.
Lead acid motive power batteries give off hydrogen gas and other fumes when recharging and for a period after the charge is complete. Proper ventilation in the battery charging area is extremely important. A hydrogen-in-air mixture of 4% or greater substantially increases the risk of an explosion.
This hydrogen evolution, or outgassing, is primarily the result of lead acid batteries under charge, where typically the charge current is greater than that required to maintain a 100% state of charge due to the normal chemical inefficiencies of the electrolyte and the internal resistance of the cells.
Most codes and regulations mandate facility design to ensure a maximum allowable limit of 1% hydrogen concentration in battery rooms. Flooded lead-acid batteries are often delivered filled with electrolyte. Once the electrodes of a battery are filled with electrolyte, the corrosion and self-discharge processes begin.
While it is particularly critical for flooded lead acid battery systems, even VRLA batteries will vent hydrogen gas under certain conditions. The objectives of this paper are the following:.

Watering is the most common battery maintenance action required from the user. Automatic and semi automatic watering systems are among the most popular lead acid battery accessories. Lack of proper watering leads to quick degradation of the battery (corrosion, sulfation....).
Best practice standards such as IEEE documents and fire code state that you must deal with hydrogen in one of two ways: 1) Prove the hydrogen evolution of the battery (using IEEE 1635 / ASHRE 21), or 2) have continuous ventilation in the battery room.
