TOKYO -- December 20, 2012

On November 14, Hitachi Ltd. (TOKYO:6501)("Hitachi") and Hitachi Plant
Technologies, Ltd. ("Hitachi Plant Technologies") signed an agreement with the
Kingdom of Saudi Arabia's King Abdulaziz University (KAU) (President, Prof.
Osama S. Tayek) for joint research on water quality monitoring technology to
be used in seawater desalination facilities.

The joint research will focus on the demonstration and validation, evaluation,
and improvement of water quality monitoring technology developed at Hitachi's
Yokohama Research Laboratory (Yokohama, Kanagawa, Japan) that will be used in
Hitachi Plant Technologies' seawater desalination plant. This work will be
conducted over a nearly two-year period in cooperation with KAU's Center of
Excellence in Desalination Technology (Executive Director Dr. Mohammed H.
Albeirutty; hereinafter "CEDT"), which is one of the most experienced
organizations in this field in Saudi Arabia, one of the world's most important
markets for seawater desalination plants.

Seawater reverse osmosis plants based on reverse osmosis (RO) membranes are
widely used to obtain potable water and industrial water in regions such as
the Middle East, which have a serious shortage of water resource. An important
task in operating the Seawater reverse osmosis plants is preventing membrane
fouling caused by the foulants included in the seawater. An accurate
assessment of seawater properties based on its monitoring is essential for
controlling fouling and ensuring stable operation of the plants because the
operating parameters must be set in view of these properties.

The water quality monitoring technology developed at Hitachi's Yokohama
Research Laboratory measures the very small amount of substances in seawater
that cause RO membrane fouling using the quartz crystal microbalance method
(QCM method). The QCM method measures the mass of minute quantities of
substances adhering to a quartz oscillator by detecting changes in the
oscillator's natural frequency induced by the mass increase. This approach has
already been developed for film thickness sensors used in semiconductor
production equipment and other applications. Hitachi and Hitachi Plant
Technologies have studied the relationship between RO membrane fouling and
water quality monitoring data using the QCM method with view to controlling
operations for minimize fouling and optimizing the cleaning and replacement
intervals of RO membranes. Using actual seawater from the Red Sea, the joint
research with KAU's CEDT will demonstrate the performance of this system and
accelerate its commercialization. The Hitachi Group plans to use the results
of the joint research to expand business in engineering, procurement, and
construction (EPC) of seawater desalinization plants and their operation and
management business.

At the signing ceremony held on November 14 at KAU in Saudi Arabia, CEDT
Executive Manager Dr. Mohammed H. Albeirutty expressed his hopes for the
project, saying, "This project is an opportunity to blaze a new trail in
seawater desalinization plants by leveraging the advanced technology of
Hitachi and Hitachi Plant Technologies." Dr. Koichi Tsuzuki, Vice President
and Executive Officer of Hitachi Plant Technologies, echoed Dr. Albeirutty's
sentiment, saying, "It is our hope that Hitachi's technologies, not limited to
the fruits of this joint research project, will contribute to the further
development of Saudi Arabia." Hitachi and Hitachi Plant Technologies will
continue to hold discussions with KAU on expanding their areas of cooperation.

In recent years, the Hitachi Group has strengthened its presence in Saudi
Arabia. In October 2009, Hitachi opened a branch in the Saudi capital of
Riyadh to serve as a base for its operations. Hitachi Plant Technologies
became the first Japanese company to sign a corporate procurement agreement
(CPA) to supply and service compressors for oil-and-gas plants with the Saudi
Arabian Oil Company (Saudi Aramco) in June 2011 and in June 2012, established
Hitachi Saihati Engineering Services Co., Ltd. to provide industrial equipment
maintenance services. In January 2013, Hitachi Plant Saudi Arabia Co., Ltd.
(provisional name) will be established as a joint venture with the El Seif
Group to provide social and industrial infrastructure construction and
engineering business. The Hitachi Group considers this joint research
agreement with KAU as an important milestone in building-up ties with Saudi
Arabian research organizations for providing solutions to regional needs
through locally-led initiatives research and development.
