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.

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).

Combined heat and power, also known as cogeneration, is an efficient process that generates electricity and captures and utilizes the waste heat produced simultaneously. It involves using a single fuel source, such as natural gas or biomass, to generate electricity through a generator or turbine. The waste heat generated during this process is recovered and utilized for heating, cooling, or other thermal energy applications. Combined heat and power systems offer higher energy efficiency, typically exceeding 80%, compared to separate production of electricity and heat. They provide cost savings, reduce fuel consumption, and contribute to environmental sustainability by maximizing the use of energy resources. Combined heat and power find applications in various sectors, including industrial, commercial, and residential settings.

Coal gasification is a thermochemical process in which coal is subject to heat and pressure in a gasifier to break it down into its chemical constituents. The resulting product, known as syngas, primarily comprises carbon monoxide and hydrogen and, occasionally, other gaseous compounds. Syngas can be used for electricity generation, as a fuel in energy-efficient fuel cell technology, and even as a chemical building block in industrial applications. Moreover, hydrogen can be extracted for use as fuel in a hydrogen economy. Also, syngas can be used to produce transportation fuels that can be a substitute for gasoline in vehicles.

Ultrapure water is the water treated to obtain the highest purity levels for use in critical cleaning and process feed applications. Ultrapure water is primarily used in the semiconductor industry, power plants, and the healthcare sector. It is obtained by combining several filtering techniques, including reverse osmosis, ultrafiltration, and ion exchange. The processes for obtaining ultrapure water are monitored by stringent specifications and standards formulated by regulatory bodies.
