據海上風能網6月27日報道，Lhyfe正在法國測試名為Sealhyfe海上制氫平臺在上個月被拖到與BW Ideol的浮動風力渦輪機Floatgen相連的SEMV-REV海上試驗場后，于6月20日開始生產首批氫氣。

Sealhyfe預計每天能夠生產多達400公斤的氫氣。

從2022年9月開始，在圣納澤爾港的一個碼頭進行了八個月的測試后，隨著投產里程碑的到來，該平臺已進入第二階段的測試，重點是在海上條件下生產氫氣。

Sealhyfe包括一個由Plug提供的1兆瓦電解槽，安裝在GEPS Techno的WAVEGEM浮動平臺上，該平臺經過重新設計，可穩定海上生產裝置。

在港口進行的八個月測試中，該平臺進行了基準測試以及技術和系統優化。通過第一階段的試驗，Lhyfe還開發了使Sealhyfe能夠完全自主運行所需遠程管理網站軟件和算法構建模塊。

該公司表示，在第一個測試階段之后，其已經更新了所有陸上和海上站點的操作規范，并且所有設備都將受益于Sealhyfe試點項目的操作優化。

在Centrale Nantes的SEM-REV海上試驗場，由OPEN-C基金會運營、位于大西洋距離法國海岸20公里的Sealhyfe通過專門為氫氣應用設計的臍帶電纜連接到該試驗場的海底樞紐。

據Lhyfe稱，在該平臺被拖至連接到集線器后，該系統在短短48小時內重新啟動并投入使用。

該公司現在將重現在碼頭進行多次測試，以便對結果進行比較，然后將進行額外的海上特定測試。

為了在海上環境中實現可靠的氫氣生產，Lhyfe計劃開發一種操作能力，包括管理平臺的運作和環境壓力以及驗證綠色和可再生氫氣生產軟件和算法。

World’s First Offshore Hydrogen Production Project Yields First Kilograms of Green Hydrogen

The offshore hydrogen production platform that Lhyfe is testing in France, named Sealhyfe, began producing its first kilograms of hydrogen on 20 June after it was towed last month to the SEM-REV offshore test site which is connected to BW Ideol’s floating wind turbine Floatgen.

Sealhyfe is capable of producing up to 400 kilograms of hydrogen per day.

With the start-of-production milestone now reached, the platform has entered the second phase of testing, which focuses on producing hydrogen in offshore conditions, after eight months of being tested at a quay in the Port of Saint-Nazaire, starting in September 2022.

Sealhyfe comprises a 1 MW electrolyser, supplied by Plug, mounted on GEPS Techno’s WAVEGEM floating platform which has been re-engineered to stabilise the production unit at sea.

During the eight months of testing at the port, the platform underwent benchmarking tests and technology and system optimisation. Through this first phase of trials, Lhyfe also developed software and algorithm building blocks necessary to manage the site remotely and to enable Sealhyfe to operate fully autonomously.

The company says that, following the first testing phase, it has already updated its specifications for all its sites, both onshore and offshore, and that all of its units will benefit from the operating optimisations trialled in the Sealhyfe pilot project.

At Centrale Nantes’s SEM-REV offshore testing site, operated by the OPEN-C Foundation and located 20 kilometres off the French coast, in the Atlantic Ocean, Sealhyfe is connected to the site’s subsea hub via an umbilical cable that was specially designed for hydrogen application.

After the platform was towed and connected to the hub, the system was restarted and on stream in just 48 hours, according to Lhyfe.

The company will now reproduce all of the tests that were performed at quay several times in order to have a comparison of results and will then be carrying out additional offshore-specific tests.

With an aim of achieving reliable production of hydrogen in the offshore environment, Lhyfe plans to develop an operating capability that involves managing the platform’s movement and environmental stresses, and validating green and renewable hydrogen production software and algorithms.
