Sažetak
Although countries around the world have increased the utilization of renewable and clean energy, the consumption of fossil fuels is still increasing, leading to an increasing emission of greenhouse gases, especially CO2 , into the atmosphere. The fundamental problem with this phenomenon is that most renewable energy sources are characterized by instability, low energy density, and difficulty in storage. The existing energy conversion technologies convert these primary energy sources into power energy, which is not a carrier and is not easy to transport and store. However, turning renewable energy resource into energy carriers, such as hydrogen, can solve the fundamental problem. This paper takes China as an example to deeply explore the current situation and shortcomings of the energy supply system, as well as the important tasks of energy development. The green, efficient, and low-cost production of sufficient hydrogen/power is the prerequisite and core, and low-cost long-term storage and transportation of sufficient hydrogen/power is the key. After years of research, State Key Laboratory of Multiphase Flow in Power Engineering has developed emerging technologies for preparing energy carriers based on renewable and fossil fuels. The development of these efficient and low-cost large-scale hydrogen/power generation technologies, as well as low-cost long-term hydrogen/energy storage and transportation technologies, can provide reliable core support for large-scale reduction of CO2 emissions and suff icient and inexpensive green hydrogen/power supply, and strategic technical support for building a new green energy supply system and ensuring national energy security.
