Corporate InformationSustainability

Hitachi's smart city concept uses technology to reduce the environmental burden while ensuring quality of life such as safety and convenience, comfort and enjoyment. We will continue to contribute to the creation of smart cities optimized for people and the environment, mindful of cultural and social considerations for each country and region.

Smart Cities and Smart Communities Worldwide

Global warming from greenhouse gases is a serious global problem. Lowering atmospheric concentrations of greenhouse gases to 450 ppm requires a major reduction in CO2. Renewable energies—hydro, wind and solar—are vital for energy and environmental challenges, but they can be unreliable and expensive. We are helping to build smart cities and communities using integrated information and control solutions, power distribution, and storage.

Breakdown of Energy-Related CO2 Emission Reductions


New Policies Scenario: A scenario that takes into account broad policy commitments and plans that have been announced by countries.
450 ppm Scenario: A scenario that restricts the global increase in temperature to 2°C by limiting concentrations of greenhouse gases in the atmosphere to around 450 parts per million of CO2.

Wind and Photovoltaic Generation and EV Demonstration Project on Maui, Hawaii

We are working on the Japan-US Island Grid Project (JUMPSmartMaui). The island of Maui in Hawaii relies heavily on fossil fuels, and aims to boost the renewable energy ratio to 40 percent by 2030. We installed charging management systems for electric vehicles (EVs)—more widely used in the future—as well as home gateways and other equipment. This will create a smart grid for a stable supply of power even with increasing reliance on renewable energy which is affected by weather conditions through this demonstration project.

µDMS: Micro Distribution Management System

The basic policy for the demonstration project is to respond to the widespread adoption of EVs, ensure a continual power supply, and make maximum use of renewable energy. We promote the smart grid environment utilizing EV charging management system and an ICT platform.

Smart Cities and Mutual Agreement

At an event to recruit volunteers for the demonstration
project in Hawaii, people could try out our car chargers.

Mutual agreement and dialogue with local communities is vital for realizing smart cities. For the Maui demonstration project, we built strong community relationships through meetings with local NPOs and leaders, being sensitive to the regional situation and culture, keeping residents informed, and creating user-friendly manuals.


Change a challenge to an opportunity

Maui is fortunate to have been selected as the site for the groundbreaking JUMPSmartMaui demonstration project. Our island-and state-are challenged by the highest rates for energy in the United States and an unsustainable dependence on fossil fuel. The cost of energy impacts our businesses, public institutions and the economic and social wellbeing of our residents. Our challenge is also an opportunity. JUMPSmartMaui represents a win-win: Maui offers a willing, ideal test-bed for Hitachi's cutting edge strategies and technologies; NEDO (New Energy and Industrial Technology Development Organization) and Hitachi invest in solutions that accelerate Maui's search for broad-scale, clean energy solutions.
As importantly, Hitachi has embraced our island community. Project leaders have placed a high priority on respecting the environmental and cultural values deeply held by our residents. They have tapped local businesses to assist with planning and implementation. They have readily adopted island traditions. All of these experiences have laid the groundwork for a productive relationship. We look forward to the results.
