Green ammonia to fuel Indonesia’s coal-fired plants?
PT Indo Raya Tenaga (IRT)*, owner/operator of the Jawa 9 and 10 ultrasupercritical coal fired units in Indonesia, has signed a memorandum of understanding with Doosan Enerbility that will see a study carried out on maximising the utilisation of green ammonia as a possible alternative fuel source for Jawa 9 and 10. These two 1000 MWe units, adjacent to the existing eight-unit 4025 MWe Suralaya coal/biomass fuelled plant in Cilegon, on the west coast of Java island, about 120 km from Jakarta, are currently under execution by Doosan Enerbility, with Doosan ultrasupercritical boilers and Siemens SST-6000 steam turbines, and are close to completion.
Following IRT’s visits to KEPRI and Doosan test facilities and to KOMIPO’s ultrasupercritical power plant in Korea, it was concluded that utilising green ammonia and green hydrogen for power generation is one of the key programmes in the energy transition roadmap to net zero being pursued by the Korean government. “Presently, Doosan is implementing the optimisation of

the ammonia burner with a target of reaching the commercial stage by 2027”, said the CEO of Doosan Power Service in his opening remarks during the visit of IRT to Doosan Enerbility’s facility in Changwon, Korea.
Previously PT Indo Raya Tenaga has concluded a joint study with PT PLN Enjiniring which found that up to 60% green ammonia was a suitable fuel source for the Jawa 9 and 10 boilers, which are equipped with selective catalytic reduction (SCR). IRT notes that SCR is essential in reducing
NOx
emissions resulting from ammonia co-firing above about 20%.
It was recognised, however, that the ammonia supply chain presents challenges. Doosan Enerbility has also signed a memorandum of understanding with Indonesia Power (IP)** on “transitioning to eco-friendly power plants” and reducing emissions. With the signing of this MOU, the two companies say they have agreed to “enter into a comprehensive partnership” aimed at pursuing the application of eco-friendly technologies at the Suralaya power plant.
“Doosan Enerbility’s various carbon neutral solutions, such as ammonia co-firing technology, hydrogen gas turbines and hydrogen liquefaction plants, will serve as an effective alternative for Indonesia in achieving its carbon reduction goals,” said Yeonin Jung, president and COO of Doosan Enerbility. “We’re hoping that this MOU will be the start of more active exchanges for pursuing carbon reduction power projects in Indonesia.”

India could become a global wind power supply chain powerhouse
India could become a key player in the global wind energy supply chain, according to the report From local wind power to global export hub: India wind energy market outlook 2023-2027, recently published by the Global Wind Energy Council (GWEC) and MEC Intelligence.
The report emphasises the huge supply chain opportunities for India in the export market, and looks at the domestic challenges of ramping up deployment of wind energy in this decade to meet ambitious targets. The report forecasts that around 22 GW of wind energy capacity will be added in India over the next five years, at the
current pace of growth. Under an accelerated growth scenario with heightened demand from central and state markets, as well as commercial and industrial consumers of clean energy, more than 26 GW could be added within this period. The government of India is targeting 140 GW of cumulative installed wind energy capacity by 2030, though various factors make it more likely that around 100 GW of capacity will be achieved by the end of the decade. The projected shortfall can still be avoided, but this will require proactive policy and industrial strategy support to help accelerate growth.

“India has an enormous strategic opportunity to leverage an invigorated domestic market and its existing wind manufacturing base and knowledge to become a key player in the global wind supply chain.”
The report highlights the fact that in 2022, 10.4 GW of tenders were issued for standalone wind and hybrid projects.
This followed the reopening of state tenders for standalone and hybrid wind, which were nearly dormant for the past few years after the introduction of the e-reverse- auction regime.
