据海上风能网6月27日报道，Lhyfe正在法国测试名为Sealhyfe海上制氢平台在上个月被拖到与BW Ideol的浮动风力涡轮机Floatgen相连的SEMV-REV海上试验场后，于6月20日开始生产首批氢气。

Sealhyfe预计每天能够生产多达400公斤的氢气。

从2022年9月开始，在圣纳泽尔港的一个码头进行了八个月的测试后，随着投产里程碑的到来，该平台已进入第二阶段的测试，重点是在海上条件下生产氢气。

Sealhyfe包括一个由Plug提供的1兆瓦电解槽，安装在GEPS Techno的WAVEGEM浮动平台上，该平台经过重新设计，可稳定海上生产装置。

在港口进行的八个月测试中，该平台进行了基准测试以及技术和系统优化。通过第一阶段的试验，Lhyfe还开发了使Sealhyfe能够完全自主运行所需远程管理网站软件和算法构建模块。

该公司表示，在第一个测试阶段之后，其已经更新了所有陆上和海上站点的操作规范，并且所有设备都将受益于Sealhyfe试点项目的操作优化。

在Centrale Nantes的SEM-REV海上试验场，由OPEN-C基金会运营、位于大西洋距离法国海岸20公里的Sealhyfe通过专门为氢气应用设计的脐带电缆连接到该试验场的海底枢纽。

据Lhyfe称，在该平台被拖至连接到集线器后，该系统在短短48小时内重新启动并投入使用。

该公司现在将重现在码头进行多次测试，以便对结果进行比较，然后将进行额外的海上特定测试。

为了在海上环境中实现可靠的氢气生产，Lhyfe计划开发一种操作能力，包括管理平台的运作和环境压力以及验证绿色和可再生氢气生产软件和算法。

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.
