2030 VisionContribute to decarbonization and effective BCP for Minato Mirai 21, to become the district’s heating and cooling supplier of choice
In April 2022, Minato Mirai 21 was recognized by the national government as a Decarbonization Leading Area. In partnership with the public sector, the district is working to create an urban model for decarbonization.
Since its founding in 1989, the mission of MM21 DHC has been to stably supply heating and cooling. As we grow and prosper along with Minato Mirai 21, we aim to be the community’s DHC supplier of choice, contributing to reducing carbon emissions in district and strengthening its BCP.
- Improvement in energy efficiency of 20% or more
- Expanding adoption of carbon-neutral heating and cooling by selling carbon-neutral heating and cooling to Central District businesses and organizations participating in the Decarbonization Leading Area project
- 50% reduction in carbon intensity
- Exploration of hydrogen use, and promotion of innovation
Decarbonizing heating and cooling
Approximately 30% of Minato Mirai 21’s CO2 emissions are generated from heating and cooling. MM21 DHC is working hard to help reduce or eliminate carbon emissions in the district.
We are further reducing our energy consumption through actions such as expanding and upgrading equipment, constructing No. 3 Plant, and using AI to increase the efficiency of plant operation. We expect to achieve 20% or greater energy-saving performance versus fiscal 2013 by 2030.
We are also seeking to decarbonize our heating and cooling energy sources (electricity, gas, etc.) so that we can commercialize and sell carbon-neutral heating and cooling that meets customers’ needs for carbon reduction. In addition, we are proactively pursuing innovation in this area, including introducing technologies for using hydrogen and capturing and using CO2.
Continuity and rapid recovery of heating and cooling supply
MM21 DHC is strengthening its disaster preparedness, including by increasing the resilience of its buildings and equipment and implementing flooding countermeasures. Our aim is to ensure continuity of supply and rapid recovery in the event that essential services are disrupted by an earthquake other natural disaster.
We are installing a backup oil-fueled gas-turbine generator and gas and oil pass-through boilers in No. 3 Plant, currently under construction. This equipment, along with the operation of centrifugal and absorption chillers, is expected to enable early implementation of the BCP and improve functionality, achieving a 30% increase in our capacity to supply heating and cooling during a major power failure.
We are also taking steps to improve community resilience. These include effecting closer coordination with customers to achieve rapid resumption of supply after recovery of essential services, and preparing for priority supply to serve specific consumers such as hospitals and temporary refuges in the event of a blackout.
- 72 hours’ continuous supply serving specific consumers such as hospitals and temporary refuges in the event of a major power failure
- If power is restored within 72 hours, supply will resume within 3 hours.
- Zero supply interruption incidents attributable to MM21 DHC
- Fair and transparent pricing in response to fluctuations in prices of inputs
Stable supply of heating and cooling
Expert heat-source equipment operators are stationed at Center Plant and No. 2 Plant round the clock every day to maintain stable supply of heating and cooling. Since the start of supply in 1989, not a single supply interruption incident attributable to MM21 DHC has occurred.
We will continue our ceaseless efforts to ensure continued operation with zero supply interruptions. Moreover, amid high energy prices and sales of carbon-neutral heating and cooling, we will set prices in a fair and transparent manner, carefully listening to customer concerns and clearly explaining our actions.
Optimal use of heating and cooling
Because Minato Mirai 21 is a mixed-use district, the introduction of DHC has proven highly effective in reducing peak energy demand across the entire district and achieving high energy efficiency.
MM21 DHC encourages customers to use heating and cooling wisely. We help them do this with services such as visualization of their heating and cooling consumption, and contract maintenance of their heating and cooling equipment.
- Visualizing each customer’s heating and cooling consumption
- Expansion of contract maintenance services for customers’ heating and cooling equipment
