Electrolytes that have both hydrogen as well as oxygen ions on one side of the cell can generate two electrolysis products, hydrogen and oxygen, in hybrid SOECs. Water electrolysis occurred at the two electrodes of hybrid SOECs, where this electrolyte was first introduced.
The integration of water electrolyzers and photovoltaic (PV) solar technology is a potential development in renewable energy systems, offering new avenues for sustainable energy generation and storage. This coupling consists of using PV-generated electricity to power water electrolysis, breaking down water molecules into hydrogen and oxygen.
An electrolyzer may be powered by solar energy to convert water into hydrogen . This is an energy-intensive electrolysis process that has so far prevented widespread deployment . Solar energy is on the rise as a low-cost power source for producing green hydrogen .
As a commercial product, the solid oxide electrolysis cell (SOEC), a green hydrogen-generating technique, is still in its infancy . For electrolysis, a stack of solid oxide fuel cells (SOFCs) typically operates in regenerative mode or backward. SOECs generate hydrogen from electricity as opposed to SOFCs, which store electric energy .
Battery-assisted electrolysis emerges as a promising solution to mitigate solar energy intermittency, albeit with ongoing research focused on cost reduction and addressing associated environmental concerns. In the end, this review serves as a roadmap for advancing the integration of electrolyzers with PV systems for sustainable hydrogen production.
It appears that the PV cell module has a high solar-to-hydrogen efficiency, potentially reaching 77.05%. This makes it a practical and effective option for generating solar hydrogen . The thermodynamic efficiencies of the PV plant remain high during sunlight and are more cost-effective than a hybrid CSP plant.
