Generators are devices that are mostly used as a source of power backup in the event of power outages. The two most predominantly used fuels in generators are diesel and natural gas. Natural gas generators are gaining popularity and adoption currently due to their benefits over their diesel counterparts.

An industrial lead-acid battery is basically a lead-acid battery designed to frequently deep discharge using most of its power capacity. An industrial lead-acid battery provides a steady amount of current over longer durations. This type of battery not only delivers a power surge when needed but also deeply discharges repeatedly.

Heliport lighting refers to a specialized lighting system designed to provide illumination and guidance for helicopter operations at heliports. It consists of various components, including elevated perimeter lights, approach lights, landing area lights, touchdown, lift-off area lights (TLOF), and wind indicator lights. These lights assist pilots in locating and safely navigating the heliport, especially during low-light conditions or at night. They help outline the heliport boundaries, guide the approach and landing phases, highlight the touchdown and lift-off areas, and provide information about wind direction and intensity.

根据国家能源局统计，截至 2023 年底，全国已建成投运新型储能项目累计装机规模达 3139 万千瓦/6687 万千瓦时，平均储能时长 2.1 小时。2023 年新增装机规模约 2260 万千瓦/4870 万千瓦时，较 2022 年底增长超过 260%。截至 2023 年底，已投运锂离子电池储能占比 97.4%， 铅炭电池储能占比 0.5%，压缩空气储能占比 0.5%，液流电池储能占比 0.4%，其他新型储能技术占比 1.2%。 

Fuel cells produce electricity by utilizing the power generated by electrochemical reactions and convert potential chemical energy into electrical and heat energy. They use external sources of chemical energy, such as hydrogen and oxygen, to produce energy. Electrochemical reactions in the fuel cells oxidize hydrogen, which reacts with oxygen to form water, releasing electrons that flow through the external circuit as electric current.

A fuel cell is a device that converts chemical energy to electrical energy in the presence of an electrolyte. It has two electrodes - an anode and a cathode, which facilitate the movement of positively and negatively charged ions to produce water and heat as by-products. Therefore, defense agencies are inclined toward fuel cell technology for their military aircraft (manned and unmanned).
