Business Description and Liquidity [Text Block]	Note 1 (a) Organization and description of business Synthesis Energy Systems, Inc. (referred to herein as “we”, “us” and “our”), together with its wholly-owned and majority-owned controlled subsidiaries is a global clean energy company that owns proprietary technology, SES Gasification Technology (“SGT”), for the low-cost and environmentally responsible production of synthesis gas (referred to as the “syngas”). Syngas produced from SGT is a mixture of primarily hydrogen, carbon monoxide and methane and is used for the production of a wide variety of high-value clean energy and chemical projects such as substitute natural gas, power, methanol, and fertilizer. Our current focus has been primarily on commercializing our technology outside China through the regional business platforms we have created with partners in Australia, Australia Future Energy Pty Ltd (“AFE”), and in Poland, SES EnCoal Energy sp. zo. o (“SEE”). Through AFE and SEE we believe we are developing energy and resource projects with the necessary commercial and financing structures to deliver attractive financial results. Our business model is to create value growth through AFE and SEE via the generation of earnings, from the licensing of our proprietary technology and the sale of proprietary equipment into those project developments, and through income from earned or carried equity ownership in resource and clean energy production facilities that utilize our technology. AFE and SEE endeavor to link long-term access to low-cost coal or renewable resources to the projects they develop as well as secure long-term contracts for product off-take thereby establishing the commercial and financing foundation for those projects. We operate our business from our headquarters located in Houston, Texas and our offices in Shanghai, China. Additionally, our partnership companies AFE and SEE have independent operations in Brisbane, Australia and Warsaw, Poland respectively.

Depreciation is computed by using the straight-line method at rates based on the estimated useful lives of the various classes of property, plant and equipment. Estimates of useful lives are based upon a variety of factors including durability of the asset, the amount of usage that is expected from the asset, the rate of technological change and the Company’s business plans for the asset.

The deferred tax assets and liabilities are classified as long-term asset or long-term liability. Valuation allowances are established when necessary based upon the judgment of management to reduce deferred tax assets to the amount expected to be realized and could be necessary based upon estimates of future profitability and expenditure levels over specific time horizons in tax jurisdictions.

Gains and losses from foreign currency transactions are included in the calculation of net loss. (o) Stock-based expense The Company has a stock-based compensation plan under which stock-based awards have been granted to employees and non-employees.

We continue to evaluate the conditions of the Yima Joint Venture to monitor for any impairments in our investment. Yima had lower production levels in the fourth June 30, 2018. June 30, 2018. Our operations are subject to stringent laws and regulations governing the discharge of materials into the environment, remediation of contaminated soil and groundwater, sitting of facilities or otherwise relating to environmental protection. Numerous governmental agencies, such as various Chinese, Australian and European Union authorities at the municipal, provincial or central government level and similar regulatory bodies in other countries, issue regulations to implement and enforce such laws, which often require difficult and costly compliance measures that carry substantial potential administrative, civil and criminal penalties or may may not not not For example, in China, developing, constructing and operating gasification facilities is highly regulated. In the development stage of a project, the key government approvals are the project’s environmental impact assessment report, or EIA, feasibility study (also known as the project application report). Approvals in China are required at the municipal, provincial and/or central government levels depending on the total size of the investment in the project. Prior to commencing full commercial operations, we also need additional environmental approvals to ensure that the facility will comply with standards adopted in the EIA. Although we have been successful in obtaining the permits that are required at this stage of our development, any retroactive change in policy guidelines or regulations, or an opinion that the approvals that have been obtained are inadequate, could require us to obtain additional or new permits, spend considerable resources on complying with such requirements or delay commencement of construction. Other developments, such as the enactment of more stringent environmental laws, regulations or policy guidelines or more rigorous enforcement procedures, or newly discovered conditions, could require us to incur significant capital expenditures. Selling syngas, methanol, glycol and other commodities is highly regulated in many markets around the world, as will be projects in our business verticals. We believe these projects will be supported by the governmental agencies in the areas where the projects will operate because coal-based technologies, which are less burdensome on the environment, are generally encouraged by most governments. However, in China and other developing markets, the regulatory environment is often uncertain and can change quickly, often with contradictory regulations or policy guidelines being issued. In some cases, government officials have different interpretations of such regulations and policy guidelines and project approvals that are obtained could later be deemed to be inadequate. Furthermore, new policy guidelines or regulations could alter applicable requirements or require that additional levels of approvals be obtained. In addition, the European Union continues to promote clean energy and climate policies and encouraging a shift away from facilities powered by coal. The Chinese government also continues to encourage newer technologies that can cleanly process coal. Although we do not The Company is subject to concentration of credit risk with respect to our cash and cash equivalents, which it attempts to minimize by maintaining cash and cash equivalents with major high credit quality financial institutions. At times, the Company’s cash balances in a particular financial institution exceed limits that are insured by the U.S. Federal Deposit Insurance Corporation or equivalent agencies in foreign countries and jurisdictions such as Hong Kong.

The impact of these changes on the prior year would have resulted in a similar change to the valuation allowance and therefore the net income tax expense/(benefit) recognized in the prior year would not have changed.
