HOUSTON, April 9, 2013

HOUSTON, April 9, 2013 /PRNewswire/ --Hainan Dongfang Henghe Energy
Development Company Ltd., ("Henghe"), based in Hainan Province, China, has
selected Synthesis Energy Systems, Inc. ("SES) (Nasdaq: SYMX) for a large
scale, 10 billion RMB (US$1.6 billion) coal waste to synthetic natural gas
("SNG") project in Jiangxi Province, China.

The Jiangxi Province project will be designed to convert coal mining wastes
into two billion normal cubic meters of SNG per year, and is expected to be
built in multiple phases. Both companies have agreed to work together
exclusively for this project over the next 12 months to complete commercial
agreements for licensing SES' technology as well as equipment supply and
service agreements. During this period, Henghe will manage development of the
project including obtaining necessary government approvals.

Ms. Li Jinmei, chairwoman of Henghe, stated, "We have confidence in SES'
technology as we see SES' Yima project begin operations. We believe the SES
technology is a good technology for China and is well suited for our Jiangxi
project because of its ability to cleanly and cost effectively convert our low
quality coal and waste coal for SNG production. We look forward to advancing
this project with SES and beginning construction sometime in 2014."

"Our track record of technology success in China, buoyed by the recent
start-up of our Yima Joint Venture plant, has resulted in a significant uptick
in inquiries from industrial companies and project developers looking to
utilize our coal gasification technology," said Robert Rigdon, president and
CEO of SES. "The Jiangxi project with Henghe is an ideal large-scale
commercial application of our technology for the conversion of very low
quality and low cost fuels into high-value products like synthetic natural
gas. We expect the project to require multiple SES gasifier systems and we
look forward to finalizing the commercial arrangements for our technology and
equipment."

About Synthesis Energy Systems, Inc.
SES provides technology, equipment and engineering services for the conversion
of low rank, low cost coal and biomass feedstocks into energy and chemical
products. Its strategy is to create value through providing technology and
equipment in regions where low rank coals and biomass feedstocks can be
profitably converted into high value products through its proprietary U-GAS^®
fluidized bed gasification technology, which SES licenses from the Gas
Technology Institute. U-GAS^® gasifies coal cost effectively, without many of
the harmful emissions normally associated with coal combustion plants. The
primary advantages of U-GAS^® relative to other gasification technologies are
(a) greater fuel flexibility provided by the ability of SES to use all ranks
of coal (including low rank, high ash and high moisture coals, which are
significantly cheaper than higher grade coals), many coal waste products and
biomass feed stocks; and (b) the ability of SES to operate efficiently on a
smaller scale, which enables the construction of plants more quickly, at a
lower capital cost, and, in many cases, in closer proximity to coal sources.
SES currently has offices in Houston, Texas, and Shanghai, China. For more
