OVERVIEW: A renewable energy feed-in tariff took effect in Japan in July 2012, and is expected to accelerate the adoption of photovoltaic power generation and other forms of renewable energy. Due to restrictions in the building of photovoltaic and wind power plants, there are expected to be increasing numbers of cases where such plants are built in remote locations far from the places where large amounts of energy are consumed, both in Japan and internationally. For this reason, problems related to the stabilization of power grids between energy production and consumption locations may grow serious. To deal with this situation, Hitachi is working towards the realization of power supply stabilization and wide-area interconnection by pursuing efforts in power system stabilizers, SVCs, energy storage systems, high voltage DC transmission systems, and other power grid technologies.

The market for video surveillance systems has been growing, with the technology being seen as essential for preventing unauthorized or criminal activity at logistics or financial services branches, and for quickly resolving violent incidents and similar. With the spread of networks in recent years, there has been growing demand for use of these systems in business. This demand extends beyond existing applications for preventing crime to also include uses such as remote monitoring to keep track of people and equipment, and image analysis to support customer operations and business management. Hitachi has been developing cloud-based video surveillance systems to meet this demand, and has plans to extend this development to future cloud services such as using image analysis for customer business support and equipment operation monitoring. © Hitachi, Ltd. 1994, 2014.

Railways are a key form of public transportation, yet the electric power shortages resulting from factors such as the impact of the Great East Japan Earthquake on nuclear power plants have made it more necessary than ever that they seek to save electricity. Another issue is the action being taken around the world to deal with the problem of global warming. Hitachi has developed a system for the storage of regenerative power that uses the same lithium-ion batteries as hybrid cars to store and reuse this energy in trains. The system was commercialized in 2007. In some cases, the installation of this system produced savings of more than 10% in power consumption. Hitachi intends to accelerate the deployment of this system to reduce railway power consumption in Japan and other markets. Source

Many countries and regions around the world are facing threats of severe water shortages or degradation of the water environment resulting from factors such as explosive population growth, rising living standards brought about by economic progress, and increasing use of industrial water Using the advanced technologies of water treatment systems, information and control systems, and energy saving systems, Hitachi has been helping protect and improve the world water environment for about a centuly. In the future, Hitachi intends to continue utilizing its high levels of both hardware and software technology built up in a variety of water-related fields to work with customers on building water distribution systems. © Hitachi, Ltd. 1994, 2013.

OVERVIEW: The scope of application of international standards has been growing as people seek ways of resolving global issues. There has also been a trend in recent times toward the introduction of standards for services. These service standards are intended to apply not to individual technologies but to actual services in a particular field. There is also a strengthening move toward international standardization of social infrastructure systems, a field that in the past did not need to take account of international standards. Hitachi is actively involved in international standardization. In the field of smart cities, Japan proposed the establishment of an ISO committee for standardizing indicators used to evaluate the performance of community infrastructure, resulting in the creation of the new ISO/TC 268/SC1 subcommittee. As a member of the Japanese team, Hitachi assisted with the proposal to establish this committee and with the writing of standards. Source
