Solar-Electrocatalytic System for Hydrogen Generation

Utilization of carbon-rich fossil fuels (e.g., coal, oil, and natural gas) in our society has led to a significant increase in CO2 emissions, resulting in the climate changes due to the ‘‘greenhouse effect’’. Lately, there is a new concept, known as hydrogen economy, which utilizes hydrogen, generated by renewable energies, as high-density energy carriers instead of electricity.

• Instead of the centralized generation of hydrogen at power plants, hydrogen fuels can be produced on-demand on the spot for the delocalized energy generation by different schemes without using any energy storage technologies, power grid and transportation systems.
• The hydrogen fuel can be generated on-demand in the local regions when it is needed, while there is no need to have a centralized generation as well as a large-scale storage and transportation of hydrogen fuels.
• Solar-driven evaporation of seawater to freshwater and solar-driven electrocatalytic hydrogen production from the pre-evaporated seawater, which can enable the large-scale deployment for eco-friendly and low-cost solar-driven hydrogen fuel production from local seawater as an alternative clean energy carrier.

• On-demand generation of large-scale and low-cost hydrogen fuels
• Multi-functionality and high-performance of micro-nanostructure electrocatalysts
• Solar-driven (e.g., photovoltaic and photothermal) water splitting
