2. South Kalimantan. 3. East Kalimantan. The Indonesian coal industry is rather fragmented with only a few big producers and many small players that own coal mines and coal mine concessions (mainly in Sumatra and Kalimantan). Since the early 1990s, when the coal mining sector was reopened for foreign investment, Indonesia witnessed a robust
201311 Prospects for commercial coal processing depend on the prices for the basic energy carriers: oil, gas and coal. According to the LTPDCI-2030 Programme (Ministry of Energy of the Russian Federation, 2010b), coal processing into liquid fuels and chemicals is forecast to be operating at the commercial scale (10–15 Mt of coal) by 2020–30. 7.3.1
2021515 Abstract. High-temperature coal tar (HTCT) is an important raw material for obtaining value-added aromatics. However, effective utilization of HTCT is not optimistic because of backward processing technology and higher energy consumption, resulting in fewer product types and lower purity. Accordingly, value-added utilization (VAU) of HTCT
2016628 India has proven reserves of coal amounting to ∼126 billion tonnes out of which ∼18 billion tonnes is metallurgical or coking coal, ∼107 billion tonnes is thermal coal, and ∼1 billion
2021219 Introduction. Coal is China’s main energy source, accounting for more than 60% of the primary energy. The status of this subject energy will be difficult to change for a long time in the future.
Just over 40 Mt of CMM were released to the atmosphere in 2022, representing more than 10% of total methane emissions from human activity. Steam coal and lignite accounted for around 75% of CMM emissions and coking coal for the remaining 25%. Underground mines were responsible for around 70% of emissions and surface mines for the remainder.

202161 Hydrogen is produced through detoxification purification, water steam conversion, high-temperature shift reactions, low-temperature shift reactions, decarbonization, and methanation of the raw materials. Because the process is rather mature, the hydrogen yield over a unit of raw material consumption is relatively high.

201941 Considering the most strict emissions standards applied in China (NOx < 50 mg/m3; SO2 < 35 mg/m3), advanced coal-fired power plants can promote the environmentally sustainable performance of thermal power plants by combining with desulfurization and denitrification equipment. The CFB coal-fired power plant is an
2022518 While hydrogen can be used in many sectors, its derivative, ammonia, has emerged as a key tool to provide flexible power generation and integrate variable renewables. Analysis by Wood Mackenzie shows that a 10% ammonia co-firing in global coal plants would translate to 200 million tonnes (Mt) of ammonia demand, a potential

IEA analysis finds that the cost of producing hydrogen from renewable electricity could fall 30% by 2030 as a result of declining costs of renewables and the scaling up of hydrogen production. Fuel cells, refuelling equipment and electrolysers (which produce hydrogen from electricity and water) can all benefit from mass manufacturing.
