Direct solar hydrogen generation via a combination of photovoltaics (PV) and water electrolysis can potentially ensure sustainable energy supply while minimizing greenhouse emissions. The PECSYS project aims at demonstrating solar‐driven electrochemical system with an area >10 m 2 high efficiency reasonable cost. Thermally integrated PV electrolyzers (ECs) using thin‐film silicon, undoped, silver‐doped Cu(In,Ga)Se silicon heterojunction combined alkaline to form one unit are developed on...
The large-scale implementation of solar hydrogen production requires an optimal combination photovoltaic systems with suitably-designed electrochemical cells, possibly avoiding power electronics for DC-DC conversion, to decrease costs. Here, a stable, solar-driven water splitting system is presented, obtained through the direct connection state-of-the-art proton exchange membrane (PEM) electrolyzer bifacial silicon heterojunction (SHJ) module three cells in series total area 730 cm2....
In order for electrolysis cells to operate optimally, mass transport must be improved. The key initial component optimal operation is the current collector, which also essential transport. Water as an educt of reaction evenly distributed by collector membrane electrode assembly. As products reaction, hydrogen and oxygen directed quickly efficiently through into channel removed from cell. second stoichiometry, includes density water volume flow rate represents ratio between supplied consumed....
Water electrolysis will be an essential element of the future energy system, with hydrogen serving as a climate-friendly storage medium. To make electrolyzers suitable for market penetration at scale, cost manufacturing megawatt must minimized, no detrimental effects to their performance and lifetime. Here we show facile cost-effective method produce one-piece Ti-based bipolar plates. Low-cost commercially readily available feedstock materials (blank sheets, expanded metals nonwovens) are...
Herein we discuss polymer electrolyte membrane (PEM) electrolysis stacks and systems developed that are optimized for direct coupling to a photovoltaic (PV) panel. One advantage of PEM is their use non-corrosive non-toxic media. Thus, safe outdoor operation can be guaranteed, even in the case leakage. The system design was adapted reduce number connection tubes, allowing series multiple at low cost high reliability. coupled PEM/PV tested under various temperature irradiance conditions. All...
A thermally-integrated solar water-splitting approach is presented, using bifunctional precious metal free catalysts based on Fe and Ni. The scalable reaches up to 13.4% solar-to-hydrogen (STH) efficiency.
A new type of energy system based on renewable sources and hydrogen technologies is put into operation at Forschungszentrum Jülich, Germany. The aim the "Living Lab Energy Campus (LLEC)" project testing optimizing systems interactions. Central components are wind power PV systems, PEM electrolysis system, conditioning subsequent gas transport in H 2 O pipelines, storage LOHC reactors use combined heat plants.
