It seems to be like Europe actually is critical about slicing its dependence on Russian fuel. An enormous LNG loophole nonetheless lurks throughout the continent’s sanctions towards Russia, however a brand new offshore wind farm deliberate for the Baltic Sea with a built-in inexperienced hydrogen angle will assist sink LNG from Russia, sanctions or not. If all goes in keeping with plan, the beleaguered waters of the Baltic will get an help, too.
Neptunus: But One other Large Offshore Wind Farm In The Baltic Sea
CleanTechnica is amongst these paying attention to the sudden burst of offshore wind and inexperienced hydrogen exercise within the Baltic Sea following Russia’s murderous rampage by Ukraine, which is now closing in on two years (see our full Baltic wind protection right here).
Referred to as Neptunus, this explicit renewable power venture is especially attention-grabbing as a result of it places the excessive profile model IKEA entrance and heart in effort to chop Europe free from Russian fossil power imports. Neptunus pairs the Swedish renewable power developer OX2 with the main IKEA retail franchisee, Ingka Group, by its Ingka Investments department.
Earlier this week OX2 introduced that the companions have simply filed their paperwork to construct Neptunus inside Sweden’s Unique Financial Zone, about 50 kilometers off the southern coast of Sweden, at Blekinge.
One other focal point is the venture’s dimension. If all goes in keeping with plan, Neptunus will sport as much as 207 generators with a complete capability of as much as 3.1 gigawatts.
“The manufacturing is estimated to about 13-15 TWh yearly, which corresponds to the present complete electrical energy consumption of the Blekinge and Skåne area,” OX2 defined in a press assertion.
Inexperienced Hydrogen And Useless Bottoms
Inexperienced hydrogen was not pre-planned into earlier offshore wind developments, however these days it’s turning into a normal function. That can be mirrored within the plans for Neptunus, with a further twist.
Inexperienced hydrogen refers to hydrogen jolted free from water, with {an electrical} present supplied by renewable power. That leaves some leftover oxygen to take care of. OX2 and Ingka suggest to place the leftovers to work, to assist re-oxygenate the troubled waters of the Baltic Sea.
“The extent of so-called lifeless bottoms within the Baltic Sea is likely one of the largest on this planet, with an space nearly twice that of Denmark,” reported the College of Stockholm, which not too long ago issued a research of the water physique’s well being.
“Nearly all water under the halocline, i.e. deeper than 60–80 meters, is now poor in oxygen and arduous or not possible for animals to stay in,” they added.
As described by lead researcher Carl Rolff, till the 1980’s the primary drivers of the issue have been the standard suspects, consisting of extra vitamins from agriculture and sewage. New anti-pollution measures after the 1980’s achieved sharp cuts in phosphorus and nitrogen, however researchers nonetheless haven’t discovered any actual indicators of enchancment within the waters.
The complicated hydrology of the Baltic Sea is additional sophisticated by inflows from the North Sea, and it stays to be seen if extra oxygen from offshore inexperienced hydrogen operations might help scale back the Baltic Sea “oxygen debt.”
OX2 has already spent two years surveying the realm with a watch on beginning building round 2030, so there may be loads of time to make a dedication about piggybacking an oxygenation system onto the brand new wind farm.
Extra Offshore Wind For Jap Europe
Within the meantime, OX2 has been relatively busy. In 2022 the corporate famous that it had a complete venture portfolio of about 23,864 meawatts within the pipeline, together with two new offshore wind tasks within the Åland space, referred to as Noatun South and Noatun North.
The numbers are spectacular, however when it comes to releasing Europe from the Russian fossil power web there may be extra to the story.
“Along with offshore wind farms within the Åland maritime zone, the Noatun tasks additionally embody a grid resolution for the distribution of electrical energy to Åland, Sweden, Finland and Estonia,” OX2 famous.
Estonia shares a border with Russia, and it’s scrambling to stage up each its border safety and its renewable power profile.
Final December, the highly effective agency Copenhagen Infrastructure Companions and the Ignitus Renewables department of the main European agency Ignitus Group received the rights to develop the very first offshore wind farm in Estonia. Earlier this week they added a second venture, they usually introduced plans to mix the 2 into one tasks.
The 2 companions intention to reap 1-1.5 gigawatts from the mixed web site when the generators begin spinning, someday round 2035.
“Having now secured each the Liivi 1 and Liivi 2 sea areas, CIP and Ignitis Renewables have a strategic place to optimize the dimensions and potential of the websites, representing a key funding in Estonia’s and the area’s transformation right into a sustainable, long-term inexperienced power hub in Europe.”
They’ll have loads of firm. Other than Neptunus, one other huge inexperienced hydrogen hub in Europe is deliberate for the Netherlands, with the electrolyzers to be powered by each wind and photo voltaic power.
Russia’s LNG loophole can be threatened by Ukraine, which is already planning to deploy its appreciable renewable power belongings to produce Europe with inexperienced hydrogen and 0 emission electrical energy.
Water, Water All over the place
That also leaves some questions on offshore wind energy within the Baltic Sea, and safety is one in every of them.
Russia has a slim fingerhold on the Baltic Sea by Kaliningrad Oblast, so in idea it, too, might get some offshore wind tasks up and operating. That’s unlikely, contemplating that Kaliningrad is the headquarters of Russia’s Baltic Fleet.
Wind stakeholders have already raised issues over indicators that Russia has been scouting the placement of offshore wind generators within the North Sea. It’s a secure guess the identical issues are at work within the Baltic Sea.
Placing that apart for the second, the opposite query that involves thoughts is water for the electrolysis techniques. Earlier iterations of electrolysis know-how required pure water so as to not gum up the gear, which signifies that seawater poses one thing of a problem.
The US Division of Power has been placing its power into growing low-cost pre-treatment techniques that allow using seawater, as a near-term resolution.
Over the long run, researchers are additionally engaged on next-generation electrolyzers that may deal with as seawater. Wastewater-to-hydrogen options are additionally starting to emerge.
In an attention-grabbing twist, scientists at Heriot-Watt College within the UK have been engaged on a system for producing inexperienced hydrogen from distillery wastewater.
“Globally, the distilling business is believed to provide round 1 billion litres a yr of wastewater,” the varsity notes, with Scotland alone contributing about 1 million liters to the overall.
“It takes 9kg of water to provide each 1kg of inexperienced hydrogen. In the meantime, each 1 litre of malt whisky manufacturing creates about 10 litres of residue,” provides Heriot-Watt supplies scientist Dr. Sudhagar Pitchaimuthu.
Thus far the outcomes look promising. In a newly revealed research, the brand new course of “produced related or barely increased portions of inexperienced hydrogen from the wastewater, in comparison with the outcomes from recent water,” the varsity reported.
You may try the research underneath the title, “From brew to scrub gas: harnessing distillery wastewater for electrolysis H2 era utilizing nano scale nickle selenide water oxidation catalysts” within the journal Sustainable Power & Fuels.

I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we carried out a restricted paywall for some time, but it surely all the time felt improper — and it was all the time powerful to resolve what we must always put behind there.
