Hy-Politics – political considerations shaping the evolution of clean hydrogen policy
Summary of the use case in Japan
The “Hydrogen Basic Strategy” adopted by the Japanese Government on 26 December 2017 (the “Hydrogen Basic Strategy”) describes the use case for hydrogen as follows:
- Power Generation: An alternative to LNG as fuel for combustion power generation;
- Mobility: Use of hydrogen as fuel for FCVs (fuel cell vehicles);
- Industrial process: Use of hydrogen for fuel cell cogeneration system; and
- Fuel Cell: Storage for decentralised power source.
The Government has been particularly active in promoting FCVs by setting up a taskforce for deregulation since the automobile is one of the key industrial sectors in Japan.
The Hydrogen Basic Strategy illustrates two key advantages to the use of hydrogen: (i) energy security and (ii) promotion of a low carbon society. Japan is scarce in natural resources and securing energy resources has always been a top priority on the national agenda. Currently Japan is heavily dependent on fossil fuels which are imported from overseas for power generation and hydrogen is one of the key potential solutions for these issues.
Hydrogen is perceived as a promising future technology by the industry but the higher costs for production and transportation relative to other energy sources is a major obstacle to the widespread use of hydrogen. The research project organised under the Cross-ministerial Strategic Innovation Promotion Program (SIP) has identified three forms of hydrogen carriers, being: (a) liquefied hydrogen, (b) chemical organic hydride, and (c) ammonium. The respective carriers have their own advantages and disadvantages but there has been a degree of competition among these carriers.
The Latrobe Valley Project illustrated below is envisaging the transportation of hydrogen in a liquefied form which needs to be below negative 253 degrees celsius. Kawasaki Heavy Industries has launched a dedicated vessel for liquefied hydrogen transportation. In contrast, Brunei-Kawasaki project mentioned above adopts the chemical carbon hydride which does not require low temperatures but involves additional processes for extracting pure hydrogen from the chemical carbon hydride. The competition among the hydrogen carriers will continue as the technologies are evolving in this field.
“Mid and Long Term Policy for Ports and Harbours “Port 2030”” published by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) in June 2018 envisages that, as a part of national port development strategy, ports should function as a base for hydrogen-related activities which include, without limitation, import, production, consumption and storage.
In conjunction with this initiative, hydrogen was highlighted in the first meeting of the public private council for offshore wind projects recently hosted by MLIT and METI as one of the promising options for maximising the ports’ efficiency and potential. For example, hydrogen can be produced by the electricity generated by offshore wind farms and be stored in a liquefied form or consumed as fuel for FCVs.
Examples of demonstration/feasibility projects in Japan
Latrobe Hydrogen Energy Supply Chain Project (“Latrobe Valley Project”): this is a pilot project for development of the hydrogen energy supply chain between Japan and Australia by producing hydrogen through brown coal gasification without CO2 emission by carbon capture and storage (CCS) and export/import the liquefied hydrogen by a special vessel from Australia to Japan. In this project, Kawasaki Heavy Industries, Ltd., J Power, Iwatani Corporation, Shell Japan Limited, Marubeni Corporation and other Japanese companies formed an association called “HySTRA” and have undertaken the processes for the brown coal gasification in Latrobe Valley, liquefied hydrogen marine transportation from Victoria, Australia and unloading in Kobe, Japan. This pilot project is supported by funding from the Japanese Government through New Energy and Industrial Technology Development Organization of Japan (NEDO) and both the Australian federal government and the Victorian state government.
Brunei-Kawasaki Hydrogen Supply Chain Project (“AHEAD Brunei Project”): this is a pioneering project for demonstrating the viability of hydrogen energy supply chain between Japan and Brunei with the funding from NEDO. Mitsubishi Corporation, Chiyoda Corporation, Mitsui & Co. Ltd., and Nippon Yusen Kabushiki Kaisha have established the Advanced Hydrogen Energy Chain Association for Technology Development (AHEAD) for this project. In this project, hydrogen is manufactured from LNG in Brunei (210 tons annually at full capacity) and then imported into Japan by utilising the organic chemical hydride method and consumed as fuel for thermal power generation facility. According to AHEAD’s announcement, the methylcyclohexane (MCH), a chemical compound of hydrogen and toluene produced in Brunei, has arrived in Japan in December 2019 and the supply of hydrogen separated in a dehydration plant to the fuel gas turbines of a local power generation plant has been commenced and under stable operation since May 2020.
Feasibility Study Program for Ammonia Co-firing in Thermal Power Generation Facility: IHI Corporation, JERA Co., Inc. and Marubeni Corporation, in consultation with Woodside Energy Ltd., participated in NEDO’s feasibility study programme for application of the ammonia as fuel for a co-firing thermal power generation plant in March 2020. In this project, the ammonia will be produced from renewable energy and/or natural gases and transported to thermal power generation facilities where the ammonia is applied as fuel for thermal power generation. Ammonia does not emit carbon dioxide when combusted, and therefore would be useful for reducing the emission of the greenhouse gases.
Queensland Hydrogen Supply Chain Project: this is a technology-verification project carried out by Queensland University of Technology (QUT), the University of Tokyo, JXTG Nippon Oil & Energy Corporation (JXTG) and Chiyoda Corporation from December 2018 to March 2019. In this project JXTG produced MCH by using the electricity generated by QUT’s PV power generator, then MCH was transported into Japan and Chiyoda Corporation successfully separated the hydrogen from MCH.
