In collaboration with CTF Solar, SunHydrogen has designed scalable thin-film solar cell module architecture that will form the basis for multiple 1m² hydrogen panel
SunHydrogen claims its unit can effectively turn water and sunlight into readily usable energy. The demonstration unit used nine modular solar panels in a square-meter array
CORALVILLE, IA – January 15, 2025 – SunHydrogen, Inc. (OTCQB: HYSR), the developer of a breakthrough technology to produce renewable hydrogen using sunlight and water, today
In this work, we report a concentrator photovoltaic-electrolysis (CPV-E) setup with a STH efficiency of 28% at 41 suns (without the use of Fresnel lenses), the highest reported efficiency using an alkaline system to date.
SunHydrogen, a company pioneering renewable hydrogen production, recently unveiled its groundbreaking 1m² green hydrogen panel demonstration. Conducted on December 11, 2024, at their Coralville, Iowa
Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size. A
It is the first hydrogen-producing integrated project for wind-solar hydrogen production in Inner Mongolia and the world''s first 100,000-ton green hydrogen demonstration
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.
