Problems solved by technology
The concentrator is a high-precision parabolic reflector, and the processing and debugging are complicated. The light concentrating is based on the principle of geometric optics, which is strongly dependent on the incident angle of sunlight, and requires a complex heliotropic device
For example, the processing, operation and maintenance costs of the trough heat collection system account for more than 50% of the investment in the entire solar thermal power station, and the power generation system is complex, which restricts the rapid development of the solar thermal power generation industry and limits the transformation and upgrading of my country's glass industry

Abstract
The invention belongs to the technical field of water electrolysis hydrogen production devices, and particularly relates to a broadband wide-angle transmission type plane metasurface condenser and a device and system comprising the same. The wide-angle condensation advantage of a planar luneberg lens, the broadband condensation advantage of a planar metasurface lens with a multi-layer cascade architecture and the solar spectrum absorption enhancement advantage of metal nanoparticles are integrated, the working temperature of 800 DEG C is provided for the chemical reaction of hydrogen production through water electrolysis of solid oxides, and an electrolytic tank is formed in the heat absorption pipe with the inverted-T-shaped section; the device is firstly assembled in a series connection mode, and the condensation heat absorption temperature is increased so as to meet the requirement for heat needed by water electrolysis hydrogen production. And then, parallel assembly is carried out, so that the hydrogen production amount is increased, and the requirements of human production and living are met.
Description
technical field [0001] The invention belongs to the technical field of electrolytic water hydrogen production devices, and in particular relates to a broadband wide-angle transmission type flat metasurface condensing mirror and a device and system including the same. Background technique [0002] Hydrogen production by electrolysis of water can not only store hydrogen as a clean and high-energy fuel, and supply power and heat through fuel cells when needed, but also can be directly integrated into or integrated with carbon dioxide to synthesize methane into the existing gas supply network to realize electricity to gas. Complementary transformation, relying on the gas system to achieve super-large-scale energy storage. Therefore, it provides a relatively effective solution to the demand for seasonal ultra-large-scale energy storage of renewable energy. [0003] The current electrolysis of water to produce hydrogen energy storage technology includes alkaline electrolysis tech...
