The Nippon Foundation Sponsors Seminar to Promote “Zero Emission Ships” [2021年06月03日(Thu)]

Participants in a panel discussion on the development of hydrogen-fueled vessels during a seminar on “zero emission ships” held at The Nippon Foundation in Tokyo on May 18, 2021. Some attended the session in person, while more than 700 others took part online.


The Nippon Foundation has sponsored a seminar to promote the development of “zero emission ships” that emit no carbon dioxide (CO2) or other greenhouse gases. These ships are expected to play a major role in Japan’s efforts to cut greenhouse gas emissions to zero on a net basis to become a carbon-neutral society by 2050.

Supported by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), the May 18 seminar attracted participants from shipping, shipbuilding and other companies and organizations across the country, with several dozen people attending in person and more than 700 others online, reflecting the keen interest in and strong commitment to contributing to the decarbonization of the maritime industry.

In my opening remarks, I stated: “Development of zero emission inland ships will spearhead innovation on a global scale. By mobilizing many future-oriented people who can reorient the existing values, let’s push ahead with the innovation.”

Mr. Naoki Fujii, MLIT vice minister for transport and international affairs, noted that at a time when Japan and the rest of the world are racing to achieve carbon neutrality to fight climate change, it was most fitting to hold a seminar on zero emission ships−and especially on the use of hydrogen to power them.

The first session focused on challenges facing the promotion of hydrogen-fueled ships, especially the need to set up schemes for providing subsidies to small businesses engaged in research and development of hydrogen vessels and the advisability of introducing a carbon tax to be levied on carbon emissions by the maritime industry to finance emission-free ship projects.

In the second session, Mr. Mitsuyuki Unno, managing director of The Nippon Foundation, presented the foundation’s scenario envisaging progress in the use of next-generation fuels to power inland ships in 2050.

For the time being, he said, Japan’s efforts to reduce greenhouse gas emissions from ships will depend mainly on the existing technologies and infrastructure, including LNG (Liquefied Natural Gas) cells and batteries. Over the medium term, however, hydrogen and ammonia will play a significant role−and especially hydrogen.

Seen as the ultimate green fuel, hydrogen only emits water during combustion and would account for some 55% of all alternative fuels to power inland ships in Japan in 2050, followed by batteries (about 38%) and ammonia (about 7%), according to the scenario.

If progress is made in the use of hydrogen and other alternative fuels as envisioned, Mr. Unno said, the economic benefits gained by the nation’s shipping and shipbuilding industries in 2050 are expected to total approximately 2,300 billion yen (about $20.9 billion).

The participants also discussed the current state of research and development of zero emission ships, schemes and incentives for putting those vessels into actual service, nurturing human resources and what they would like the government to do to help develop zero emission vessels.

If we are to help Japan to become a carbon-neutral country by 2050, it is essential to start designing and developing hydrogen and other zero emission ships now, because ships built today will stay on the water for decades, given the long lifetime of modern vessels (typically 25 to 35 years).

I was greatly impressed by the participants’ strong commitment and dedicated effort. The foundation is determined to support the nation’s fledgling fleet of zero emission ships for decades to come.
