“…The method examined in the present study consists in creating an electrothermal breakdown channel in the formation between electrodes positioned in wells. The breakdown channel is then used as a resistive heater element for heating [6,7]. It is economically reasonable to increase the distance between wells as much as possible.…”

The paper is devoted to the study of the characteristics of partial discharges in solid fossil fuels. The appearance of partial discharges in solid fuels occurs at very low voltages, which are not typical for most dielectrics. The activity of partial discharges leads to the onset of rock breakdown. The characteristics of partial discharges in the oil shale of the Huadan deposit (China), presented in the work, indicate the voltage value at which partial discharges arise and breakdown occurs, and also show how these characteristics depend on voltage. We attempted to explain the low value of the voltage of partial discharges in solid fuels, as well as to substantiate the possibility of using partial discharge characteristics to predict the breakdown of the interelectrode space for use in the technology of in-situ heating and the pyrolysis of solid fuels. Keywords: Oil shale, subterranean conversion, field distribution simulation, apparent chage measurement.

“…Commercial coal gasification facilities operate in the US, the PRC, and Australia (CoalAge 2021). Coal gasification technology in Kazakhstan has not reached the commercial stage and remains in the R&D stage with several projects related to fixed-bed, plasma, and underground coal gasification(Tokmurzin et al 2019;Messerle, Ustimenko, Lavrichshev 2021;Martemyanov et al 2021).Unlike natural gas, coal in Kazakhstan has no resource shortage problem. Blue hydrogen production will not compete with current coal use, and thus coal could provide feedstock for the longer term.…”

The energy transition is driving governments and industries to adopt various measures to reduce their climate impacts while maintaining the stability of their economy. Hydrogen technologies are one of the central topics in the energy transition. Different nations have different stances on it. Some governments see hydrogen as a decarbonization tool or part of their energy security strategy, while some others see it as a potential export commodity. While identifying priorities for the future, Kazakhstan should clearly define the role of hydrogen in the country’s long-term energy and decarbonization strategy. This work presents the first country-scale assessment of hydrogen technologies in Kazakhstan by focusing on policy, technology and economy aspects. A preliminary analysis has shown that Kazakhstan should approach hydrogen mainly as a part of its long-term decarbonization strategy. While coping with the financial risks of launching a hydrogen economy, the country can benefit from the export potential of low-carbon hydrogen in the near term. The export potential of low-carbon hydrogen in Kazakhstan is justified by its proximity to the largest hydrogen markets, huge resource base, and potentially low cost of production (in the case of blue hydrogen). Technology options for hydrogen transportation and storage for Kazakhstan are discussed in our work. The paper also identifies target hydrogen utilization areas in emission sectors regulated by Kazakhstan’s Emissions Trading System.
