JR East and Iwatani Push Toward a Next-Generation Hydrogen Train
Building on HYBARI, the partners are moving toward higher-pressure hydrogen storage and longer operation. The question is whether fuel cells can replace diesel on hard-to-electrify regional lines.
Can Japan Build a Hydrogen Highway From Fukushima to Fukuoka?
Japan’s plan concentrates heavy hydrogen trucks and large stations along freight corridors rather than spreading infrastructure everywhere at once.
JFE Uses Green Hydrogen to Make Direct-Reduced Iron in Chiba
Renewable hydrogen from Yamanashi was transported to Chiba and used in direct reduction. The trial probes one of steelmaking’s hardest decarbonization problems.
Kawasaki Plans Japan’s First High-Pressure Pipeline for Bulk Hydrogen Transport
A roughly four-kilometer high-pressure pipeline is planned to connect a future liquid-hydrogen terminal with industrial demand and reduce reliance on truck delivery.
Maibara Tests an Inland Green-Hydrogen Hub at Japan’s Transport Crossroads
At a crossroads linking Tokai, Kansai and Hokuriku, the project studies hydrogen production, CNT demand, refueling and possible use of oxygen and waste heat.
Kawasaki to Build a 40,000 m³ Liquid-Hydrogen Carrier for JSE
With tank volume about 32 times Suiso Frontier’s, the new carrier is meant to move liquid hydrogen from demonstration scale toward commercial logistics.
Kobe Tests a Next-Generation Liquid-Hydrogen Fuel Supply for Power Generation
The system pumps liquid hydrogen above critical pressure before vaporization, potentially reducing gas-compression work while creating opportunities to use cryogenic cold.
Don’t Throw Away Minus 253°C: Obayashi and Iwatani Turn Liquid Hydrogen’s Cold Into Building Energy
A new heat exchanger recovers about 90% of the cold available during liquid-hydrogen vaporization, opening a route to cooling buildings and refrigeration.
Whisky, Water and Hydrogen: Hakushu Tries to Reinvent Industrial Heat
A 16 MW P2G system is feeding hydrogen boilers for sterilization steam at Suntory’s water plant, with direct-fired whisky distillation under study.
Can 15 Years of Support Create a Real Hydrogen Market? Japan’s Price-Gap Experiment Begins
Japan will bridge part of the cost gap between low-carbon hydrogen or ammonia and incumbent fuels for 15 years, then test whether supply can survive without the bridge.
Hydrogen Gets Cheaper When Demand Clusters: Inside JERA’s Hekinan Hub
Price-gap support targets the molecule; hub support targets shared tanks, loading and distribution. Hekinan is the test of demand clustering around one large anchor.
A Quiet Hydrogen Dinner on Tokyo Bay: How AMANE Could Make Fuel Cells Feel Ordinary at Sea
Lady Crystal’s successor will combine Yanmar fuel cells, Toyota hydrogen storage and ENEOS supply, turning quiet electric propulsion into part of the passenger experience.
From Expo Showcase to Working Port: Tokyo Gives Hydrogen Ship Mahoroba a Second Life
The pure-hydrogen passenger vessel from Expo 2025 is moving to Tokyo Port for public rides and education, testing whether demonstration hardware can become everyday infrastructure.
Build the Hydrogen Drone in Japan: Robodex, TEPCO and a Kyotango Fuel Cell Take On the Flight-Time Wall
A domestic fuel-cell stack joins Robodex and TEPCO’s hydrogen-drone work, targeting missions where endurance can change inspection, logistics and disaster response.
After Giving Up the Car Keys, Can You Still Get to the Store? ELEMOs and Robodex Bet on Hydrogen Mobility
A license-free four-wheel platform could use lightweight replaceable hydrogen cylinders, but real value depends on easy handling, local fuel access and economics versus batteries.
Nagasaki Marks 81 Years Since the Atomic Bombing and Renews Its Appeal for Peace
Eighty-one years after 11:02 a.m. on August 9, 1945, Nagasaki connects survivor memory and reconstruction with a world still shadowed by nuclear weapons.
Kumamoto Earthquake Leaves a 33-Kilometer Surface Rupture
A 33-kilometer surface rupture offers a physical map of underground failure and new evidence for understanding the earthquake and rebuilding.
Japan’s Food Self-Sufficiency Rate Falls to a Record-Low 37%
Imported grain, shrinking farmland and fewer farmers leave Japan’s food system exposed to international supply disruption and price shocks.
Megumi Ogata Warns of Unauthorized AI ‘Voice Theft’ From Japanese Performers
Is a voice data, performance, or identity? Unauthorized generative-AI cloning is forcing Japan to confront contracts, copyright and personality rights.
