Kamojang Geothermal Power Plant (PLTP) officially became the first geothermal-based green hydrogen producer in Southeast Asia. The green hydrogen plant (GHP) at this new renewable energy (EBT) plant is the 22nd GHP built by PT PLN (Persero) and will supply green hydrogen for the Senayan Hydrogen Refueling Station (HRS) which was inaugurated on Wednesday (21/2) yesterday.

The geothermal-based green hydrogen is produced from condensation water from the Kamojang PLTP electricity production process. PLN plans to increase the capacity of the GHP at Kamojang PLTP so that hydrogen production will be even greater.

PLN President Director Darmawan Prasodjo said that PLN continues to innovate in accelerating the end-to-end hydrogen ecosystem in Indonesia. Through the presence of GHP, Darmawan said, PLN also supports the development of hydrogen vehicles which are known to be economical and low in emissions.

“We want to try green hydrogen from a pure new and renewable energy production process. So, we built a GHP at Kamojang PLTP, there is an additional 4.3 tons per year,” Darmawan said.

With the operation of the GHP at Kamojang PLTP, PLN currently has 22 GHPs spread across Indonesia that can produce 203 tons of green hydrogen per year. Darmawan detailed, from the total production of 203, 75 tons of hydrogen will be used for the operational needs of the plant. Meanwhile, 128 tons will be used to support the development of the hydrogen vehicle ecosystem.

According to him, assuming each car travels 100 km / day, the total green hydrogen production capacity can be used for 438 cars in a year and can reduce fuel import energy by 1.59 million liters per year into domestic energy.

“From the upstream side, we can complete it, from the downstream we are building HRS as a pilot project, later there will also be a hydrogen center here,” Darmawan said.

National Research and Innovation Agency (BRIN) Principal Expert Researcher Eniya Listiani Dewi supports PLN in presenting HRS as an innovation in supporting green transformation in the transportation sector. Eniya also encouraged the green hydrogen ecosystem to continue to be improved in line with the high public demand for environmentally friendly transportation.

“This is a historic moment to achieve a golden Indonesia 2045, which is not only advanced but also clean and sustainable. In the future, there is still a lot of homework to complete the ecosystem as well as the demand. We will certainly encourage public transportation such as buses and ships,” Eniya explained.
