Japan progresses on hydrogen neighbourhood

A hydrogen powered residential compound consisting of 5,632 privately-owned/rental flats, nursing homes, a day-care centre and other facilities is being built in Harumi, Japan.

The project is scheduled to be completed in time for the Tokyo 2020 Games where the site will perform as the Olympic Village for the games.

The new site will be a flagship neighbourhood for urban lifestyles. The neighbourhood is made up of five zones and will feature a full-scale hydrogen infrastructure system, the first of its kind in Japan.

The Harumi Flag announcement followed the Government’s announced plans for the environment and sustainability, which stated ‘initiatives to build a hydrogen society’ back in 2016.

Among other hydrogen proposals, the Government also announced plans for residential development for the Olympic Village after the Tokyo 2020 Games which consisted of three pillars:

  1. Build a hydrogen supply station for Bus Rapid Transit (BRT) systems and fuel cell vehicles
  2. Install next-generation fuel cells for common-use spaces and commercial buildings
  3. Install EneFarm (residential fuel cell) to all privately owned residences

Harumi Flag will feature a hydrogen station which will be located within the site. An underground pipeline system will deliver hydrogen from the station to five residential blocks, this stage has already been complete.

JXTG Nippon Oil & Energy is responsible for the construction and operation of the hydrogen station that will be located on a neighbouring piece of land, leased from Tokyo Metropolis.

The company will supply hydrogen BRT transportation system and local bus service fuel cell vehicle fleet, both of which will connect urban and bay areas. It will also produce hydrogen within the station to be sent to residential blocks.

Harumi Eco Energy Co., Ltd., a wholly owned subsidiary of Tokyo Gas, is responsible for the pipelines and hydrogen distribution to town blocks. The company will also own the hydrogen fuel cell generators which will be installed in the residential blocks.

Panasonic will be responsible for the supply of hydrogen fuel cell generators to each residential block. The company plans to bring out fuel cells capable of delivering power output of 5kW and rated energy conversion efficiency of 56%.
