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.

A heating and cooling system known as an air source heat pump pulls heat from the outside air and transfers it inside a building for space heating or cooling. It functions as an energy-efficient substitute for conventional heating, ventilation, and air conditioning (HVAC) systems by compressing refrigerant gas to absorb and release heat. Owing to their adaptability and suitability for use in commercial, industrial, and residential settings, air source heat pumps help save energy and have a smaller negative environmental impact.
