It plans to use the technology to support CCU adoption by municipalities and companies and contribute to wider use of carbon recycling.<\/p>\n\n\n\n<p>CCU refers to capturing CO2 emitted from factories and reusing it to produce fuels, chemicals and other materials. Mitsubishi Electric said a lack of established evaluation methods has made it difficult to determine what types and volumes of CCU should be introduced into regional energy systems to cut emissions economically in normal times while enabling energy self-sufficiency during emergencies.<\/p>\n\n\n\n<p>The method sets multiple regional conditions that could arise during natural disasters, including power outages, water supply disruptions and fuel supply stoppages, and models the probability of those conditions changing over time. It can then quantify the benefit of introducing CCU that allows a region to remain self-sufficient for a certain period even when electricity and fuel supplies are interrupted, while identifying the lowest-cost system configuration that balances emissions reductions and resilience.<\/p>\n\n\n\n<p>Mitsubishi Electric said the model defines wind and flood damage as involving power outages, while a major earthquake is defined as causing simultaneous power outages, water supply disruptions and halts in fuel deliveries. It models state transitions at intervals of one to 24 hours. Even without considering transitions between wind-and-flood disasters and major earthquakes, the number of state transitions exceeds 100 million by day six and 1 trillion by day nine.<\/p>\n\n\n\n<p>To handle that scale, the system uses stochastic dynamic programming to aggregate expected future costs at each point in time into value functions, and improves approximation accuracy with a cutting-plane approach based on randomly generated state-transition samples. Removing unnecessary planes during approximation helps contain memory requirements for large-scale problems, while parallel computing can shorten processing times for long-duration analyses broken into smaller time-based problems.<\/p>\n\n\n\n<p>The company implemented a parallel computing program using MPI on commercially available server clusters and achieved significant acceleration.<\/p>\n\n\n\n<p>Japan has promoted regional decarbonization and disaster preparedness in parallel as the country faces frequent earthquakes, typhoons and heavy rain. The release referred to the concept of a &#8220;regional circular and ecological sphere,&#8221; a Japanese policy framework aimed at maximizing local resources to address environmental, social and economic issues together.<\/p>\n\n\n\n<p>Mitsubishi Electric has previously worked on regional energy demonstrations, including the Hachinohe &#8220;Water Flow Returned as Electricity&#8221; project conducted with Mitsubishi Research Institute and the city of Hachinohe under a commission from NEDO, a Japanese national research and development agency focused on energy and industrial technology.<\/p>\n\n\n\n<p>Mitsubishi Electric Group posted consolidated revenue of 5.8947 trillion yen ($37.5 billion) in fiscal 2025, and has more than 200 group companies and about 150,000 employees worldwide.
