Not only should energy utilization not be taken into accounts just in terms of its profits, but its efficiency (availability of fuel sources) and impacts on the environment should also be taken into accounts.
Climate Change is an environmental issue currently becoming a global concern. This research was aimed at finding solutions to solve current environmental problems one of which was by helping reduce the greenhouse effect or global warming using the technology of CO2 (carbon dioxide) gas adsorption either with local materials or with new materials that were being developed.
Adsorption technology can be applied in gas storage, cooling, or other applications in the health sector. Carbon dioxide capture (Carbon Capture) results will play a crucial role in industrial areas producing combustion gases such as steam/gas powerplants or powerplants using a lot of fossil fuel. Conventional cooling systems categorized as not environmentally friendly directly impact the greenhouse effects and ozone layer depletion. An adsorption cooling system utilizing solar energy (renewable energy) advantageously employs an environmentally-friendly working fluid such as water. It is then moved with a clean and environmentally friendly source of energy. Since the solar energy potential in Indonesia is vast, it is very possible to implement this system. Countries such as Germany, Japan, and Singapore have researched adsorption cooling systems utilizing solar energy.
In a rapidly-developed industrial world, people often encounter a problem of waste adversely affecting its surrounding environment. Any waste produced in a liquid, gas, and solid form must be controlled. Some of the waste produced by many industries is exhaust gas resulting from a combustion unit. If the exhaust gas is released in a large amount, it will undoubtedly create various problems such as global warming. One solution to that problem is to capture carbon dioxide gas contained in the gas using multiple methods.
Moreover, a strategy needs to be employed to reduce its emissions to the air. For instance, carbon capture is employed through an adsorption process by utilizing adsorbents derived from activated carbon. These raw materials are abundantly available in Indonesia, especially from waste either in plants, animals, or minerals such as rice husks, animal bones, and coal.
A new approach to analyzing an energy system is called exergy analysis, conducted through multi-objective optimization. For example, although thermodynamics, economics, and environmental science are different disciplines, they are interrelated in an exergy analysis. With exergy analysis, we can find out how such limited energy on earth can be wisely used for the benefit of humankind.
