Can a solar hydrogen production plant co-generation a kilowatt-scale pilot plant?

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.

What is solar photovoltaic (PV) power generation?

Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.

What is an off-grid PV system?

Off-grid (stand-alone) PV systems use arrays of solar panels to charge banks of rechargeable batteries during the day for use at night when energy from the sun is not available. The reasons for using an off-grid PV system include reduced energy costs and power outages, production of clean energy, and energy independence.

Are solar-to-fuel efficiencies based on Gibbs free energy?

While solar-to-fuel efficiencies are typically based on the Gibbs free energy under standard conditions 37, it is common in the water electrolysis field for voltage efficiencies to be reported on an enthalpy basis (HHV) 34, and therefore both definitions (discussed further in Supplementary Note 4) will be used here for completeness.

What is STH efficiency based on Gibbs free energy?

This corresponds to 20.3% ± 2.3% and 22.6%, respectively, when based on Gibbs free energy. The STH efficiency for lab-scale PEC devices is typically calculated based on Gibbs free energy 37 in the same manner as the device-level fuel efficiency defined in this work and so can be compared on an equal basis.

Is solar concentration a viable route to high-power-density photoabsorbers?

In particular, solar concentration has been shown to be a promising route towards economically competitive, high-power-density devices permitting the use of more expensive photoabsorber materials 22, 23, 24, 25, 26.
