The government held the New and Renewable Energy Policy Council (President Ju Young-jun) on December 29, 2020, and the ‘5th Development and Use of Renewable Energy Technology’ The basic dissemination plan is deliberated and confirmed (in below, the fifth basic plan).
In the fifth basic plan, solar and wind power were set at 39.3% and 35.1%, respectively, and fuel cells were set at 12.5%, respectively.
In particular, the construction sector plans to supply 20% of the energy used to new buildings as new and renewable energy using the mandatory Zero Energy Building (ZEB) system with the goal of supplying new and renewable energy of 3,456,000 TOE .
The vision of the V Basic Plan is to “ accelerate the transition towards a low-carbon economy and society by establishing a base for the diffusion of renewable and sustainable energy ”. To this end, the expansion of the sectoral coupling focused on renewable heat and green hydrogen will be promoted.
Accelerating the realization of a low-carbon economy and societyFive major innovations such as △ diffusion △ market △ demand △ industry △ infrastructure were suggested as strategies for the fifth basic plan.
Innovation in diffusion is promoted by diversifying participants and locations, expanding distribution, and revitalizing private and joint investment. In particular, if ZEB’s energy independence rate exceeds the standard, it plans to induce further expansion of new and renewable energy by supporting installation subsidies.
To improve profitability, we will change the RPS market to focus on long-term contracts and increase the RPS obligation ratio to 38%, the level necessary to meet the 2034 supply target. In addition, the REC weighting system is reorganized to induce technological development and investment in new renewable energy facilities.
In particular, we will promote the diffusion of new and renewable heat, a non-electric renewable energy source, as a mandatory method for each supply and demand objective. Through this, it is hoped to achieve efficient energy use, minimization of conversion losses and a balanced supply of new and renewable energy.
To create diverse bases of demand for renewable energy, companies and public institutions, focused on RE100, can purchase renewable energy and recognize its use.
Furthermore, for a carbon-neutral society, sectoral coupling (link between energy and non-energy sectors) is promoted to convert and use renewable energy in other energy sources. To this end, the development and demonstration of the P2X technology will be implemented based on the annual forecast of excess supply availability.
We create a new market for new and renewable energies through R&D linked to commercialization. In particular, it promotes the creation of a hydrothermal energy market through R&D to improve the performance of hydrothermal heat pumps and operating systems, the revision of KS certification standards and pilot projects. Taking into account the future performance of hydrothermal energy, the range of renewable heat will be expanded. In addition, a 100MW class green hydrogen mass production system will be established in 2030 through a green hydrogen demonstration project using renewable energy.
We started to strengthen the system and maintain the operations management system. To this end, it supports timely access to the grid through preventative grid investments and improves the grid operating system to respond to grid congestion and mitigate fluctuations in renewable energy.
For carbon neutrality in all sectors other than power generation, sectoral coupling between energy sources focused on green hydrogen will be activated using P2X technology. To revitalize the coupling of the sector, the mandatory provisions for each type of energy, such as heat, fuel and energy, will be integrated.
Technological development is also promoted for each energy source. In the solar energy sector, △ High-efficiency and high-reliability Jeonilsa solar heat collection and high-density heat storage core technology △ Solar heat-based building cooling and industrial heat supply system technology △ The commercialization of large-scale export solar power generation systems and the development of absorption and storage technology above 600 ℃ will be promoted. .
In the geothermal field, exploration technology for exploration and evaluation of geothermal resources is developed to ensure the economic viability of geothermal energy △ high temperature heat pump unit using low GWP refrigerant △ hybrid geothermal heat pump system and technology low temperature geothermal power generation system.
The hydrothermal field will be developed with △ hybrid river water heating and cooling system technology and regenerative heat △ complex technology to improve the membrane filtration water treatment process by applying heat from water △ water utilization technology deep low temperature applied to installations with high energy consumption.
