Special Issue Information

Dear Colleagues,

In response to the global challenge of climate change, more and more economies have announced the goal of “Net-Zero”. Decarbonization of energy systems plays an important role in mitigating climate change. The power system will likely experience a profound transformation to achieve zero carbon emissions in the future. The latest Sixth Assessment Report of the United Nations Intergovernmental Panel on Climate Change (IPCC) states that “in pathways limiting climate warming to 1.5 °C, almost all electricity will need to rely on the supply from zero- or low-carbon sources in 2050”. It is necessary to develop renewable energy and fossil energy electricity with low-carbon technologies.

Clear, stable, and well-designed policies are essential for reducing emissions. On the one hand, effective renewable energy policies have a good effect on integrating renewable energy, stimulating renewable energy investment and consumption. On the other hand, the carbon emission trading policy is a tool for controlling greenhouse gas (GHG) emissions based on market mechanisms. Two aspects are crucial for the sustainable energy system. Therefore, the purpose of this Special Issue, entitled “Sustainable Energy Systems: Integrating Renewable Energy Carbon Trading and Electricity Markets”, is to expand the study of the depths of sustainable energy systems, with a focus on clean and low-carbon energy policies, and address the pertinent economic, social, and environmental challenges. This Special Issue will publish new contributions related to renewable energy policies, sustainable energy systems, emission trading systems, low carbon energy transformation, energy structures, and integrating renewable energy.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  1. Renewable energy policies and management;
  2. Low-carbon energy transformation and sustainable development;
  3. Emission trading system and low-carbon technologies;
  4. Integrated renewable energy and energy structure optimization;
  5. Renewable and low-carbon energy policy synergy;
  6. Other topics related to sustainable energy systems.

I look forward to receiving your contributions.

The production and use of hydrogen are encouraged by the European Union through Delegated Acts, especially in sectors that are difficult to decarbonize, such as the industrial and transport sectors. This study analyzes the possibility of partial decarbonization of the existing plant in the petrochemical industry, with a partial transition from natural gas to renewable hydrogen, as a precursor to the adoption of the hydrogen economy by 2050. This study was based on the example of a plant from the petrochemical industry, namely an existing fertilizer plant. Namely, in the petrochemical industry, hydrogen is produced by steam-reforming natural gas, which is needed in the process of producing ammonia, one of the basic raw materials for mineral fertilizers. By building an electrolyzer at the location of the existing fertilizer plant, it is possible to obtain renewable hydrogen, which enters the ammonia production process as a raw material. The electricity from which hydrogen is produced in the electrolyzer is provided through Power Purchase Agreement contracts concluded with electricity producers from 12 wind power plants. The results of this study show that the production of renewable hydrogen at the location of the analyzed plant is not profitable, but due to the specificity of the process of such an industry, the high consumption of natural gas, and large savings in CO2 emissions which can be achieved by the production of renewable hydrogen, investment is needed. With a 370 MW electrolyzer, about 31,000 tons of renewable hydrogen is produced, which represents about 50% of the hydrogen needs of the analyzed plant. By producing renewable hydrogen for part of the needs of the analyzed plant, a saving of about 300,000 tons of CO2 emissions is achieved in relation to the production of gray hydrogen, which contributes to the partial decarbonization of the analyzed plant. The authors are aware that the current market opportunities do not allow the profitability of the investment without subsidies, but with the advancement of technology and a different price ratio of electricity, natural gas, and CO2 emissions, they believe that such investments will be profitable even without subsidies.
