Hydrogen is widely regarded as a sustainable energy carrier with tremendous potential for low-carbon energy transition. Solar photovoltaic-driven water electrolysis (PV-E) is a clean and sustainable approach of hydrogen production, but with major barriers of high hydrogen production costs and limited capacity. Steam methane reforming (SMR), the .
A system-wide model is developed that uses meteorological data to estimate how much solar power would be generated and how much hydrogen would be produced as a result. Then, using the model, a framework is suggested for calculating and simultaneously optimizing the amount of hydrogen produced and levelized cost of hydrogen (LCOH).
The balance-of-systems (BoS) costs were the largest factor in differentiating the PEC and PV-E systems. No single or combination of technical advancements based on currently demonstrated technology can provide sufficient cost reductions to allow solar hydrogen to directly compete on a levelized cost basis with hydrogen produced from fossil energy.
It is proposed that the more feasible mode is photovoltaic hydrogen production + first stage: compressed hydrogen energy storage + second stage: natural gas mixed with hydrogen pipeline transmission + parallel second stage: gas storage (tank) storage.

6 FAQs about [How much is the profit of photovoltaic hydrogen production and energy storage]
Can solar cells reduce the cost of PV hydrogen production?
Future technological advances in PV–hydrogen production systems, such as perovskite solar cells (PSCs) and noble metal-free cocatalysts for enhanced photocatalytic H2 production [ 3, 4, 5 ], will play an important role in further reducing the levelized cost of PV hydrogen production.
What is solar PV-E for hydrogen production?
Solar PV-E for hydrogen production converts fluctuating PV electricity to stable chemical energy, and provides a stable and time-shifted energy source to support the power grid and address practical energy demands. In addition, the products of water electrolysis (H2, O 2) are produced separately at the two electrodes of the electrolytic cell.
What factors affect the future cost of PV-powered hydrogen production?
4.2.2. Projection of Future Levelized Cost of PV-Powered Hydrogen Production The uncertainty in the technological progress of both PV and electrolyzer hydrogen production is an important factor affecting the future cost of PV hydrogen production, which will, in turn, affect its economic efficiency.
Is solar energy a viable option for green hydrogen production?
The current barrier to the widespread commercial adoption of green hydrogen production using solar energy is its economic viability as the cost is much higher than that of the conventional hydrogen production using fossil fuels , .
Does the size of a photovoltaic system affect hydrogen production?
Overall, when the size of the photovoltaic system was additionally considered as a decision variable for a given annual hydrogen production required, the overall trends for LCOH, hydrogen generation, and capacity factor are compatible to the results of the previous simulation case studies.
Should solar power be a battery or a hydrogen storage technology?
Solar electricity production and storage using either batteries or PEC hydrogen technologies are currently an order of magnitude greater in cost than electricity prices with no clear advantage to either battery or hydrogen storage as of yet.
