It has no viral launch campaign, no sleek consumer interface, and no celebrity endorsement attached to it. But the MARMOK-A-5, designed by Spanish engineering firm IDOM, just did something that deserves far more attention than it\u2019s getting. It may be one of the more quietly significant design stories of the year.<\/p>\n<p>In May 2026, an updated version of the MARMOK-A-5 was successfully deployed at the Biscay Marine Energy Platform (BiMEP), off the coast of Bilbao, as part of the EuropeWave Pre-Commercial Procurement program. IDOM is one of three finalists competing for a share of a \u20ac13.4 million budget to develop and test next-generation wave energy <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a>.

The main structure is a floating spar buoy, 5 meters in diameter and weighing 162 tons. Inside it sits a cylindrical water column. As ocean waves pass through, the water inside rises and falls like a piston. That motion compresses and expands an air chamber at the top of the buoy, and the resulting rush of air spins a turbine. That turbine generates electricity, which <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/trip-and-travel\/\" data-internallinksmanager029f6b8e52c=\"10\" title=\"Trip &amp; Travel\" target=\"_blank\" rel=\"noopener\">travel<\/a>s to shore through a subsea cable. No burning, no drilling, no fuel. Just water moving the way it always has.<\/p>\n<p>The technology has been in development for years. IDOM first deployed the original MARMOK-A-5 at BiMEP back in 2016, making it the first wave energy converter ever connected to the Spanish state electricity grid. That alone was historic. The version now in the water is significantly upgraded, featuring a newly developed power take-off system, controllable turbine blades, onboard batteries, and intelligent control systems built to optimize performance in real, unpredictable high-seas conditions.<\/p>\n<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-03.jpg\" alt=\"\" width=\"1280\" height=\"960\" class=\"alignnone size-full wp-image-626340\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2026\/05\/21\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/\" data-jpibfi-post-title=\"IDOM\u2019s 42-Meter Steel Buoy Just Proved Wave Energy Can Actually Work\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-03.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-03.jpg\" alt=\"\" width=\"1280\" height=\"960\" class=\"lazyload alignnone size-full wp-image-626340\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2026\/05\/21\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/\" data-jpibfi-post-title=\"IDOM\u2019s 42-Meter Steel Buoy Just Proved Wave Energy Can Actually Work\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-03.jpg\"><\/p>\n<p>What strikes me about this project is how deliberately it was built. Every iteration, every sea campaign, fed into a deeper understanding of how ocean energy behaves at scale. IDOM didn\u2019t rush to market. They observed, adjusted, and came back smarter. The redesigned system focuses on improving power performance while keeping the one quality that sea deployments demand above all else: reliability. A beautiful machine that can\u2019t survive the North Atlantic is just expensive wreckage.<\/p>\n<p>Among the milestones from this latest deployment, one is worth calling out: the MARMOK-A-5 is now the first WEC to connect electrically to the grid through the HarshLab buoy at BiMEP. It sounds like a technical footnote, but it\u2019s a meaningful shift in how ocean energy infrastructure can be tested and eventually scaled. The ability to gather live, grid-connected data from a genuinely harsh marine environment is exactly the kind of proof point that moves wave energy from \u201cpromising concept\u201d to \u201cserious contender.\u201d<\/p>\n<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-04.jpg\" alt=\"\" width=\"1280\" height=\"960\" class=\"alignnone size-full wp-image-626341\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2026\/05\/21\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/\" data-jpibfi-post-title=\"IDOM\u2019s 42-Meter Steel Buoy Just Proved Wave Energy Can Actually Work\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-04.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-04.jpg\" alt=\"\" width=\"1280\" height=\"960\" class=\"lazyload alignnone size-full wp-image-626341\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2026\/05\/21\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/\" data-jpibfi-post-title=\"IDOM\u2019s 42-Meter Steel Buoy Just Proved Wave Energy Can Actually Work\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-04.jpg\"><\/p>\n<div class=\"code-block code-block-2\" style=\"margin: 8px 0; clear: both;\">\n<div style=\"padding: 4px; margin: 18px auto 20px; text-align:center;\"><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-7222236028814181\" crossorigin=\"anonymous\" type=\"420641e9062ce39b98094b55-text\/javascript\"><\/script><br \/>\n<!-- In-Content-Ads-2 --><\/p>\n<p><script type=\"420641e9062ce39b98094b55-text\/javascript\">\n<\/script><\/div>\n<\/div>\n<p>Wave energy has long sat in the shadow of wind and solar.

The ocean covers more than two-thirds of the planet\u2019s surface, and most of that constant motion still goes completely untapped. The MARMOK-A-5 is still a prototype, rated at just 30 kilowatts. But prototypes are how industries start.<\/p>\n<p>I keep thinking about how much of what will eventually power our lives is currently sitting, mostly unnoticed, off some coast. Not announced with a keynote. Not trending. Just quietly working, enduring salt and storm, sending electricity down a cable while the rest of us scroll past. The MARMOK-A-5 might be one of the least glamorous objects in clean energy right now. But it might also be one of the most important.<\/p>\n<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-05.jpg\" alt=\"\" width=\"1280\" height=\"960\" class=\"alignnone size-full wp-image-626342\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2026\/05\/21\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/\" data-jpibfi-post-title=\"IDOM\u2019s 42-Meter Steel Buoy Just Proved Wave Energy Can Actually Work\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-05.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-05.jpg\" alt=\"\" width=\"1280\" height=\"960\" class=\"lazyload alignnone size-full wp-image-626342\" data-jpibfi-post-excerpt=\"\" data-jpibfi-post-url=\"https:\/\/www.yankodesign.com\/2026\/05\/21\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/\" data-jpibfi-post-title=\"IDOM\u2019s 42-Meter Steel Buoy Just Proved Wave Energy Can Actually Work\" data-jpibfi-src=\"https:\/\/www.yankodesign.com\/images\/design_news\/2026\/05\/idoms-42-meter-steel-buoy-just-proved-wave-energy-can-actually-work\/marmok-05.jpg\"><\/p>\n<div class=\"yanko-preferred-source\" style=\"margin: 24px 0 16px;
