ACH Aluminum Corporation of China Ltd

Synthesis Energy Systems, Inc. (SES) (NASDAQ:SYMX), a global energy and gasification technology company enabling clean, high-value energy and chemical products from multiple feedstocks, reports a progress update from Suzhou Thvow Technology Co., Ltd. (THVOW) (Shenzhen listing code:002564) regarding the first of three previously announced natural gas replacement projects under construction for Aluminum Corporation of China Limited (CHALCO) (NYSE:ACH) (HKEx:2600) (SSE:601600), located in Zibo City, Shandong Province. THVOW has reported that the Zibo City project, which entered its commissioning phase in June 2015, has achieved an important milestone with the first of the two gasification systems having successfully completed 72 hours of continuous full-load testing. Once all testing work has been completed and the project turned over to CHALCO, the Zibo Project would become the largest domestic Chinese gasification project of its type.

The test results confirmed that the performance of the first of two SES Gasification Technology (SGT) gasification systems installed in the Zibo Project meets the required design requirements. During the continuous full-load test, the SGT gasifier system produced 110% of the required design syngas capacity, reaching 43,000 NCM (normal cubic meters) per hour of clean syngas. Additionally, the energy content of the syngas also exceeded the design requirements by 10%.

"The SES technical team has been working closely with our Tianwo-SES JV partner and our China JV partner's ICCDI design institute to help achieve this operating milestone. During this commissioning phase, the project has been routinely supplying the Shandong CHALCO branch with syngas for more than a month as the teams complete commissioning and refine the operation of the gasification systems," stated DeLome Fair, President SES Technologies, LLC. "Our SES Gasification Technology has very broad flexibility regarding the range of coal feedstocks it can gasify and this, combined with very high gasification efficiency, lower water consumption and lower construction cost than comparable technologies, has the potential to bring significant value to projects using our technology.

"This first CHALCO project at Zibo City is making another important step in demonstrating these key attributes of our technology which we believe is the future of coal gasification," added Ms. Fair.

Total construction order commitments of approximately 650 million Yuan ($102 million) for the three projects were announced in December 2014 between Aluminum Corporation of China, China's largest alumina and primary aluminum producer, and Innovative Coal Chemical Design Institute (Shanghai) Co., Ltd. (ICCDI). ICCDI is the general contractor supplying all the engineering, construction and balance of plant equipment for the three projects. The total order value for these projects to Tianwo-SES for technology and equipment supply from ICCDI, a subsidiary of Suzhou Thvow Technology Co., Ltd. (STT) (Shenzhen listing code:002564), is expected to be approximately 140.3 million Yuan ($22 million). Tianwo-SES Clean Energy Technologies Co., Ltd. (Tianwo-SES) is SES's joint venture with STT.
