Special Issue Information

Dear Colleagues,

The concept of a hydrogen economy originated during the 1960s, developing into the modern-day "the third hydrogen wave", which has recently gained considerable attention as a promising solution to the challenges faced in decarbonization, energy security, and energy transition. The hydrogen economy is central to meeting global energy needs, fostering a transition from fossil fuels to renewable forms of energy. The hydrogen economy is the chain of production, distribution, and efficient utilization of hydrogen in various sectors, including transportation, industry, and power generation. Hydrogen can be produced using several different methods. The most common methods include steam methane reforming, electrolysis, and biomass gasification; however, some common challenges include expensive production methods, infrastructure development, and the need for large-scale renewable energy. In addition, there are concerns regarding storage and transportation, and safety is paramount. Despite these limitations, the hydrogen economy represents an effective option for a sustainable energy future. Governments, industries, and research institutions worldwide are investing in research and development to unlock the full potential of hydrogen as a clean energy solution.

Low or even zero carbon dioxide emissions will be an essential requirement for energy supplies in the near future. Besides transport and electricity generation, industry is another large carbon emitter. Hydrogen produced by renewable energy provides a flexible way of utilizing that energy. Hydrogen, as an energy carrier, could be stored in a large capacity compared to electricity. In Sweden, hydrogen will be used to replace coal for steel production. This paper discusses how the need for electricity to produce hydrogen will affect the electricity supply and power flow in the Swedish power grid, and whether it will result in increased emissions in other regions. Data of the Swedish system will be used to study the feasibility of implementing the hydrogen system from the power system viewpoint, and discuss the electricity price and emission issues caused by the hydrogen production in different scenarios. This paper concludes that the Swedish power grid is feasible for accommodating the additional electricity capacity requirement of producing green hydrogen for the steel industry. The obtained results could be references for decision makers, investors, and power system operators. Full article
