Abstract

Oversupply of electrical energy is a big problem faced by PLN today. One alternative solution for solving this problem is the opportunity to convert Power to Gas. An example of a case study in this paper is Hydrogen gas. In addition to the market demand that continues to increase from year to year, both on a local and global scale. Hydrogen is also considered to significantly reduce greenhouse gas emissions, especially those from renewable energy. Indonesia is an archipelagic country where water is more than 60% of its territory. Moreover, Indonesia is blessed with sunshine that can shine all year round. These two great potentials can be utilized to produce cleaner hydrogen using Floating PV and Water Electrolysis. In this research, two models were developed that will produce Hydrogen gas for the industrial sector with a pressure of 200 bar for every 10 m3 and Oxygen gas for every 6 m3 through electrolysis sourced from the PLN grid is close to a renewable generator. The example in this study is Cirata Floating PV with an installed capacity of 192.4 MWp and a Power Purchase Agreement (PPA) with a PLN of 145 MW (AC). The annual output of electrical energy is obtained from modeling using the PV Syst 7.1 software. In this paper, the first model is made by utilizing the excess power from the PPA. It's called model A. Furthermore, a second model is made by considering the oversupply of the utility grid (PLN) in the Java-Bali system, assuming that all electrical energy output of the Cirata Floating PV is used as the basis for capacity production at the electrolysis plant, which in this paper is referred to as model B. Both models were simulated based on several scenarios. It was found that model A gets the highest IRR of 17.12% and Model B can get the highest IRR of up to 20.86%. In addition to obtaining the feasibility of the Power to the Gas project, this paper also calculates the potential for reducing CO2 emissions from the two models, namely S07,763.70 kg CO2eq for model A and 163,824,121.31 kg CO2eq for model B.
