Merdeka Battery to build new HPAL plant

Indonesian nickel miner Merdeka Battery Materials (MBMA) and partners have signed definitive agreements to construct a high-pressure acid leach (HPAL) plant on the Morowali industrial park, Sulawesi. The unit will have a nameplate capacity of 90,000 t/a of contained nickel in mixed hydroxide precipitate (MHP). PT Sulawesi Nickel Cobalt (SLNC) will construct and operate the plant adjacent to the existing HPAL plant operated by PT Huayue Nickel Cobalt (HNC). SLNC will source and process laterite nickel ore through a 20 year commercial agreement with MBMA's SCM mine, starting from the commissioning date. An ore preparation plant will be built at the SCM mine to enable ore transportation via pipeline to the SLNC processing plant at IMIP. The total combined investment for constructing SLNC (including interest incurred during construction) is expected to be approximately $1.8 billion according to Merdeka. Construction of the project commenced in January 2025 and is expected to reach commissioning stage within 18 months.

The odyssey of green ammonia: optimising levelised cost

Green ammonia production facilities can be situated in remote areas with access to often fully off-grid renewable power supply. This article examines plant concepts and discusses the challenges and solutions for these plant architectures. Through a case study, an efficient and innovative methodology to compare options and optimise the sizing of the plant is presented. The methodology addresses the intermittency of the power production, the flexibility limits of the main process units, and the costs of investment and operation, using proprietary techno-economic dynamic simulation software, Odyssey.
