Can solar hydrogen production be scaled?

Our findings demonstrate that scaling of solar hydrogen production via photocatalytic overall water splitting to a size of 100 m 2 —by far the largest solar hydrogen production unit yet reported to our knowledge—is feasible, with further scaling in principle possible without efficiency degradation.

What is solar hydrogen production through water splitting?

Solar hydrogen production through water splitting is the most important and promising approach to obtaining green hydrogen energy. Although this technology developed rapidly in the last two decades, it is still a long way from true commercialization.

What is the cost of solar hydrogen production from water?

An economic assessment gave a hydrogen prodn. cost of 7.98 kg-1 and 14.75 kg-1 of H2 for, resp. a 55 MWth and 11 MWth solar tower plant operating 40 years. Liu, G.; Sheng, Y.; Ager, J. W.; Kraft, M.; Xu, R.Research advances towards large-scale solar hydrogen production from water. EnergyChem.2019, 1, 100014, DOI: 10.1016/j.enchem.2019.100014

How much hydrogen does a solar system produce?

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.

Can solar energy make hydrogen?

One of the most sustainable ways to make hydrogen is to use solar energy to split water into hydrogen and oxygen. This can be done using photoelectrochemical (PEC) systems that combine a photovoltaic device and an electrolyzer device. The PV device absorbs sunlight and generates electricity that drives the electrolytic splitting of water.

How is hydrogen produced from water using solar energy?

The prodn. of hydrogen from water using solar energy via a two-step thermochem. cycle is considered. The 1st, endothermic step is the thermal dissocn. of ZnO (s) into Zn (g) and O2 at 2300 K using concd. solar energy as the source of process heat.
