Can hydrogen storage be integrated with rooftop photovoltaic systems?

This study focused on the modelling and optimization of hydrogen storage integrated with combined heat and power plants and rooftop photovoltaic systems in an energy system in central Sweden. Three different scenarios (S0–S2) were designed to investigate the impacts on the system flexibility and operational strategy.

What is the operational strategy of a hydrogen storage system?

A large share of the power stored as hydrogen is surplus power generated from the rooftop PV systems. Therefore, the operational strategy of the hydrogen storage system is similar to that of the storage in scenario S1. However, on several occasions, the amount of power to hydrogen is decreased due to reduced supply from thermal plants.

What are a-type solar energy to hydrogen conversion & storage devices?

A-type devices for solar energy to hydrogen conversion and storage 3.1.1. A-1 type device The most common photoelectrochemical configurations consist of a single PEC cell with all electrodes immersed directly in an electrolyte ( Fig. 3 a, hereafter referred to as A-1).

Are solar-based devices suitable for (photo)electrochemical hydrogen generation and reversible storage?

In Section 3, several architectures of solar-based devices for (photo)electrochemical hydrogen generation and reversible storage were critically discussed from the perspective of the operating principles, (photo)electrochemical performance of integrated components, and the overall efficiency of hydrogen generation, storage, and release.

What is solid-state hydrogen storage?

Conventional PEC devices require downstream technologies to capture and store the generated hydrogen gas for its further use as an energy carrier or a fuel. Among various methods, solid-state hydrogen storage appears particularly attractive due to its safety, long-term stability, and application flexibility.

Can hydrogen storage meet a power deficit in a regional energy system?

The regional energy system including the CHP plants and heat-only boilers integrated with rooftop PV systems and power-to-gas storage is considered as the reference scenario. The other scenarios are described to investigate the potential of the hydrogen storage and the fuel cell application to meet the deficit of power supply in the system.
