Kawasaki Marien

Installation of H2One™ in Kawasaki was carried out in collaboration with Kawasaki City at Kawasaki City Port Promotion Association Hall and Higashi-Ogishima-Naka Park (a public sports and recreational facility known as “Kawasaki Marien”). Demonstration operation started on April 20, 2015. This installation will present the effectiveness of the Hydrogen BCP System in emergency situations, and of the Hydrogen Energy Management System in normal use. Toshiba will continue to improve the efficiency of the overall system, in addition to futher enhancement of the hydrogen storage function, as a future energy supply system for local production and local consumption.

Toshiba has announced that it will take the lead in a demonstration project in Hokkaido that will establish the viability of a locally-based supply chain to support low-carbon, hydrogen power systems for small communities. The five-year project will run from 2015 to 2019, in cooperation with the Hokkaido prefectural government and Kushiro-shi and Shiranuka-cho, and will cover the generation, storage, transportation and use of hydrogen in power and heat generation.

Toshiba Fuel Cell Power Systems Corporation Begins Demonstration Research into Pure Hydrogen Fuel Cell System in Yamaguchi Prefecture, Japan

Toshiba Fuel Cell Power Systems Corporation started a demonstration research of its newly developed next-generation 700-watt pure hydrogen fuel cells, in collaboration with Yamaguchi Liquid Hydrogen Corporation, Chofukosan Co., Ltd and Iwatani Corporation.
The demonstration research was selected for support by Yamaguchi Prefecture and funded by the Yamaguchi Industrial Strategic Research & Development Fund established in 2014. Toshiba Fuel Cell Power Systems Corporation will collect operating data from the installed systems until 2017, and use it to further improve power generation efficiency. The fuel cell systems will provide lighting and air-conditioning at Tokuyama Zoo and Shunan Local Wholesale Market. The zoo will use the warm water produced by the power generation process for showers to wash animals, the market to wash vegetables.

Toshiba has announced that it will participate in the Levenmouth Community Energy Project in Fife, Scotland, a major 4-year project to investigate the potential of hydrogen as a future fuel. The project is funded by the Local Energy Challenge Fund.Electricity generated by wind and solar power will be used to power a hydrogen producing water electrolysis system, and the hydrogen will be stored and used as a fuel source for hybrid commercial vehicles (HCV) powered by fuel cells and diesel engines. Toshiba will deploy its hydrogen energy management system (H2 EMS), which is designed for optimal production and storage of hydrogen based on electricity supply and demand forecasts. Toshiba will also handle overall system control, allowing it to collect operating data from the entire system, including the H2 EMS, water electrolysis systems and HCV, for utilization in future projects.

a Kyushu Resort Hotel

On March 14th 2016, H2One™ has entered operation in the Phase-2 building of the Henn na Hotel, at the Huis Ten Bosch theme park in Nagasaki, Kyushu.

The long hours of summer sunshine of Kyushu, the third largest and southernmost of Japan’s main islands, allow H2One’s™ photovoltaic energy system to generate enough renewable energy to meet all the requirements of the 12 rooms in the Henn na Hotel’s Phase 2, and additional power to electrolyze water and produce hydrogen. The hydrogen is stored in the system’s integrated tank, ready for use on demand, and in winter powers fuel cells that generate electricity and hot water. The H2One’s™ capacity is sufficient enough to supply Henn na Hotel’s Phase 2 with electricity all year round.

The H2One™ installed at Henna Hotel deploys a hydrogen storage tank made with a new hydrogen storage alloy that achieves much improved high-density storage. The tank is less than one-tenth the size of the conventional model it replaces, and suitable for use even in small spaces.

the City of Yokohama’s Port & Harbor Bureau

On April 1st 2016, the first commercial unit of H2One™ has started operation as an emergency power supply and load management system in Yokohama, Japan. The system has been installed at the Yokohama Cargo Center (YCC) on Daikoku Futo, an artificial island and pier in the Port of Yokohama.

The unit at YCC, ordered in October last year and this is the first time has been operated this month as a local government, is a Business Continuity Plan (BCP) H2One™. If a disaster knocks out power supply to Daikoku Futo, the system will convert stored hydrogen to electricity, allowing YCC to maintain communications for as long as 72 hours, and help to secure continuity of port operations. In normal everyday use, H2One’s hydrogen energy management system will support peak shift, which optimizes management of hydrogen production, power generation and storage to reduce demand for mains power at times of high demand.
