Kazakhstan possesses significant natural resources, including coal, oil, natural gas, and uranium, and also has substantial potential for utilizing renewable energy sources such as wind, solar, hydropower, and biomass. However, the country currently relies heavily on fossil fuels for electricity generation. Coal-fired power plants account for 75% of the total electricity production, raising concerns about greenhouse gas emissions and their detrimental impact on human health and the environment. In December 2020, at the Climate Ambition Summit, the President of Kazakhstan announced a new goal for the country to achieve carbon neutrality by 2060. To attain this objective, the government faces the ambitious task of developing a strategy for the development of hydrogen energy in Kazakhstan. This review extensively discusses Kazakhstan’s main energy resources, the potential for low-carbon and green hydrogen production, existing and prospective pilot projects in the field of hydrogen, as well as the challenges and barriers hindering the development of hydrogen energy in Kazakhstan. Authors consider existing research, national reports, energy strategies, and plans to discuss the prospects for hydrogen energy development in Kazakhstan. The transition to hydrogen energy in Kazakhstan requires the development of a comprehensive roadmap that takes into account various aspects such as production, infrastructure development, policy support, and international cooperation. Currently, the country lacks a roadmap for hydrogen energy development that considers these crucial aspects. Therefore, as a result of this review, we have developed a new roadmap for hydrogen production by 2040 in Kazakhstan, incorporating various technologies. Authors believe this roadmap will be valuable information for the government to develop a national strategy for the active development of hydrogen energy in Kazakhstan.

The power sector confronts a crucial challenge in identifying sustainable and environmentally friendly energy carriers, with hydrogen emerging as a promising solution. This paper focuses on the modeling, analysis, and techno-economic evaluation of an independent photovoltaic (PV) system. The system is specifically designed to power industrial loads while simultaneously producing green hydrogen through water electrolysis. The emphasis is on utilizing renewable sources to generate hydrogen, particularly for fueling hydrogen-based cars. The study, conducted in Skikda, Algeria, involves a case study with thirty-two cars, each equipped with a 5 kg hydrogen storage tank. Employing an integrated approach that incorporates modeling, simulation, and optimization, the techno-economic analysis indicates that the proposed system provides a competitive, cost-effective, and environmentally friendly solution, with a rate of 0.239 $/kWh. The examined standalone PV system yields 24.5 GWh/year of electrical energy and produces 7584 kg/year of hydrogen. The findings highlight the potential of the proposed system to address the challenges in the power sector, offering a sustainable and efficient solution for both electricity generation and hydrogen production.

Humanity is being forced to alter how we use energy sources, to move away from fossil fuels and focus instead on renewable, especially solar energy. This transformation may prove to be the long sought-after “holy grail” of energy.

On 14 January 2021, the Polish Ministry of Climate and the Environment submitted for public consultation the draft Polish Hydrogen Strategy until 2030 with a perspective until 2040. The project defines goals and activities related to developing national competencies and technologies for building a low-emission hydrogen economy. The draft announces the preparation of the “Hydrogen Law”, which is to be a package of changes to currently existing acts, particularly the Polish Energy Law. However, the proposals presented in the strategy do not seem to be fully consistent with the vision of the development of the future regulation of the hydrogen market presented by the European Commission. The article presents the Polish Hydrogen Strategy’s most important assumptions regarding the proposed legislative changes and discusses them in the context of the European strategy. The main focus is on two aspects related to the planned legislative changes that seem to be the most important at this stage in order to stimulate the development of the hydrogen market: the definition of hydrogen and the decision upon which production methods will be supported, and the future regulation of the hydrogen market.
