China: Taiwan Cement (TCC) commissioned a 107MWh energy storage project at its Yingde plant in Guangdong province in August 2023. Subsidiary NHOA Energy worked on the project that linked the battery storage capacity to a 42MW waste heat recovery (WHR) system and a 8MWp solar photovoltaic unit. It uses lithium iron phosphate batteries supplied by Ningde Times.

The company’s say that the project is one of the largest industrial microgrids in the world. It is intended to provide energy flexibility to the cement plant by using NHOA Energy’s proprietary energy management system to manage peaks in energy demand and acting as a backup for critical equipment to avoid damage caused by sudden blackouts.

The NHOA Energy storage project is expected to store about 46000MWh/yr of electricity and save just under US$3m/yr in electricity costs. The system will also support the Guangdong Provincial Government’s energy storage development policy and be eligible to associated subsidies of over US$350,000/yr.

Giuseppe Artizzu, the chief executive officer of NHOA Energy, said “NHOA Energy’s proprietary energy management system will optimise the generation and consumption profile of the industrial microgrid, while also supporting the regional grid towards its 100% green energy objective, taking the energy transition in the area one step forward in total accordance with NHOA Group’s and TCC’s shared mission of fostering a positive change for the future of our planet.”

South Korea: Ssangyong Cement plans to install a waste heat recovery (WHR) unit at its Donghae plant in Gangwon. The upgrade will be operational by August 2018, according to the Maeil Business Newspaper. The new unit is expected to save the cement producer about 33% of its electricity costs or US$24m/yr.

The investment is the largest that the cement producer’s owner Hahn & Company has approved since it took control. The WHR will work with an energy storage system (ESS) that was installed in March 2018. The ESS saves power consumption by storing energy during the night and then using it during the day. The 22MWhr storage system is power by powered by 2880 batteries. The company said that it would save it at least US$2.4m/yr.

Ssangyong Cement’s Donghae plant is one of the largest in the world with a cement production capacity of 11.2Mt/yr across seven production lines. It occupies an areas of 11.3MM².
