    　View Summary

    A thermal power plant employing amine-based post-combustion CO2 capture (PCC) is a key technology for low-carbon, dispatchable power sources for the carbon-neutral electric power sector. Power-to-heat amine-based PCC is likely an economically promising system operation, which conducts CO2 absorption along with the power generation and facilitates CO2 desorption through a heat pump driven by exceptionally inexpensive electricity procured during peak power generation periods from electricity market via the grid. The combination of mathematical modelling and cost analysis evaluated the annual profits of the proposed system in future electricity markets (2030–2050) in Japan, which was predicted by an energy system optimization model. The results demonstrated that employing power to heat amine-based PCC instead of the conventional one increased the annual profits by approximately 2–27%. Notably, depending on economic factors (e.g., electricity market prices, capacity factor, or interest rate), annual profits were positive without further improvement in the amine-based PCC technologies. This result indicates that now is the time to move from laboratory investigations to real-world implementation and that techno economic analysis regarding investment decision is more important rather than calculation of carbon capture costs to showcase the feasibility of thermal power plants with PCC, propelling its swift implementation.

  • Development of a Global Energy and Mineral Supply-Demand Model Considering Resource Constraints and Material Balances of Lithium, Cobalt, and Nickel

    Hamada Ryo, Otsuki Takashi

    Journal of Japan Society of Energy and Resources   46 ( 4 ) 177 - 188  2025.07  [Refereed]

    　View Summary

    A stable and sustainable supply of critical minerals becomes an important policy agenda from climate change and economic security perspectives. This study newly develops a global energy and mineral supply-demand model to assess the cost-effective energy technology choice considering resource constraints and material balances of critical minerals. We focus on lithium, cobalt, and nickel, which are the basic materials for lithium-ion batteries for mobility and stationary uses. The simulation results suggest the following two points. First, resource constraints of these three minerals affect the optimal penetration of BEV (battery electric vehicles) and stationary batteries. In particular, conventional NMC (nickel manganese cobalt oxide) batteries are constrained by the availability of nickel and cobalt resources. Nickel and cobalt-free batteries, such as LFP (lithium-iron phosphate) batteries, would be necessary to accelerate the deployment of BEV and stationary batteries. Second, from the viewpoints of lithium supply and demand, our results imply that lithium-ion batteries for vehicles would be the main demand, rather than stationary batteries. Lithium brine resources play a key role in meeting the demand in the long-term.

  • Model Analysis of the Role of E-Methane in Realizing Net-zero CO2 Energy Systems in Japan

    Otsuki Takashi

    Journal of Japan Society of Energy and Resources   46 ( 4 ) 199 - 212  2025.07  [Refereed]

    　View Summary

    Synthetic methane (e-methane) can contribute to supplying carbon-neutral heat and electricity while utilizing existing technologies and infrastructures. This study investigates the role of e-methane in Japan’s energy system by 2050. The author employs an energy system optimization model that encompasses the entire energy system with detailed modeling for e-methane supply (e.g., innovative e-methane productions and e-methane imports) and consumption (e.g., industry, transport, and power generation). Key findings include the following three points. First, imported e-methane would be a cost-effective option for industries and buildings. In the industry, fuel switching from coal and oil to natural gas in the medium term and then to e-methane in the longer term is estimated to be cost-effective for decarbonizing heat demand. Electrification is important for buildings, although e-methane can be a part of the optimal final energy mix. Second, our results imply the potential of e-methane as a fuel for large-scale power generation, whereas e-methane for road transport is projected to be modest. Finally, this study found that the innovative e-methane production process can reduce the CO2 abatement cost by 7%-16% in 2050. E-methane is estimated to improve the economic feasibility of net-zero CO2 energy systems.

    　View Summary

    Abstract

    We study Japan’s net-zero emissions target by 2050 in a multi-model framework, focusing on residual emissions and carbon dioxide removal (CDR). Four energy-economic and integrated assessment models show similar but stronger strategies for the net-zero target, compared to the previous, low-carbon policy target (80% emissions reduction). Results indicate that around 90% (inter-model median) of the current emissions are reduced through abatement, including improved energy efficiency and cleaner electricity and fuels. Models deploy new options such as CDR based on carbon capture and storage (CCS) (bioenergy with CCS and direct air carbon dioxide capture and storage) and hydrogen to achieve net zero. The scale of CCS-based CDR deployment reaches an inter-model median of 132Mt-CO2/yr. The median hydrogen share of final energy in 2050 increases from 0.79% to 6.9% between the low-carbon and net-zero scenarios. The CDR sensitivity analysis reveals that limiting the use of CDR significantly increases the mitigation costs for net zero. Achieving Japan’s net-zero goal will require exploring methods to reduce residual emissions, including demand-side solutions, and accelerating responsible CDR policies.

    　View Summary

    The authors’ previous assessment indicated that the marginal electricity cost in 2050 in Japan is more than doubled in an energy system based on a 100% renewable power supply compared to the cost-optimal system. However, some assumptions may be conservative given the recent developments, including the cost of variable renewable energy (VRE) and energy storage technologies and the availability of dispatchable renewable power generation (such as biomass-fired). Therefore, to test the robustness of the previous assessment, this study conducts a sensitivity analysis with a focus on these factors, using an energy system optimization model with a detailed temporal resolution. Simulation results imply that the high marginal electricity cost in the “100% renewable power system” is partially due to the costs of managing VRE’s seasonality. Low-cost energy storage and dispatchable renewable power plants can curb the marginal electricity cost. However, the results also suggest that the marginal cost in these sensitivity cases remains high compared to the cost-optimal system, still posing economic challenges to the system based on a 100% renewable power supply.
