Hydrogen ships are moving from future concepts to practical applications, and three pictures of different types of hydrogen ships clearly outline a clear development path: from the ultimate vision to a small prototype with mature technology to real zero-emission transportation in the city.
氫能船舶正從未來概念走向實際應用,而三張不同類型的氫能船圖片,恰好構成了一條清晰的發展軸線：從極致願景,到技術成熟的小型原型,再到城市中真正落地的零排放交通。
The first image shows a luxury hydrogen yacht with avant-garde shapes and smooth lines.
第一張圖展示的是一艘造型前衛、線條流暢的豪華氫能遊艇。
It presents a futuristic vision of hydrogen-powered marine propulsion, with a minimalist metal shell and an inverted bow: an emission-free, vibration-free, near-silent luxury experience.
它以極簡金屬外殼和倒斜船首呈現氫能對海上移動的未來圖像：無排放、無震動、近乎無聲的奢華體驗。
This concept ship primarily uses liquid hydrogen and large fuel cells, representing the ultimate application of hydrogen energy technology on high-power ships and symbolizing the direction and ambition of the entire industry.
這類概念艦多採用液態氫與大型燃料電池,是氫能技術在高功率船舶上的極致呈現,也象徵著整個產業的方向與企圖心。
The second image returns to a more pragmatic level: YANMAR's hydrogen-fuel-cell high-speed dinghy.
第二張圖則回到更務實的層面：YANMAR 的氫能燃料電池高速小艇。
This small vessel, painted in red and white, is the actual size at which hydrogen energy is most likely to land first.
這艘紅白塗裝的小型船隻,是氫能最有可能率先落地的實際尺寸。
It can be equipped with high-pressure hydrogen storage cylinders and fuel cell modules, providing smooth propulsion, low noise, zero warm-up start-up, and minimal maintenance requirements, making it ideal as a basic platform for inspection, scientific research, port management, or coastal operations.
它能搭載高壓儲氫瓶與燃料電池模組,提供平順推進、低噪音、免暖機啟動與極低的維護需求,非常適合作為巡查、科研、港務管理或沿岸作業船艇的基礎平台。
The third map represents the future of urban mobility: medium-sized hydrogen ferries.
第三張圖則代表城市交通的未來：中型氫能渡輪。
It uses fuel cells as the main propulsion and tens of kilograms of high-pressure hydrogen storage, providing long-term quiet, exhaust-free navigation in harbor waters.
它以燃料電池作為主力推進、搭配數十公斤的高壓儲氫,在港灣水域中提供長時間的安靜、無廢氣航行。
For port cities, hydrogen ferries can reduce noise, oil odors, and air pollution, and also symbolize a key turning point in hydrogen energy, moving from demonstration to daily transportation.
對於港口城市而言,氫能渡輪能改善噪音、油味與空氣汙染,同時也象徵氫能從示範走向日常運輸的關鍵轉折。
The technical feasibility of small hydrogen vessels includes a proven 20–60 kW PEM fuel cell, 350 bar hydrogen storage, 6–12 hours of sailing time, and full compliance with safety standards such as ISO, DNV, and IEC.
小型氫能船的技術可行性包含成熟的 20–60 kW PEM 燃料電池、350 bar 儲氫、6–12 小時航行能力,以及完整的 ISO、DNV、IEC 等安全規範。
Although the construction cost is about twice that of diesel ships, the overall life-cycle cost is more competitive due to the lower maintenance and energy efficiency of fuel cells.
雖然建造成本約為柴油船的兩倍,但因燃料電池維護量低、能源效率高,整體生命周期成本更具競爭力。
