It seems to be like Europe actually is critical about slicing its dependence on Russian fuel. A large LNG loophole nonetheless lurks throughout the continent’s sanctions in opposition to 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 line with plan, the beleaguered waters of the Baltic will get an help, too.
Neptunus: But One other Big 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 via Ukraine, which is now closing in on two years (see our full Baltic wind protection right here).
Known as Neptunus, this explicit renewable vitality challenge is especially fascinating as a result of it places the excessive profile model IKEA entrance and middle in effort to chop Europe free from Russian fossil vitality imports. Neptunus pairs the Swedish renewable vitality developer OX2 with the main IKEA retail franchisee, Ingka Group, via 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 challenge’s measurement. If all goes in line 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 Lifeless 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 offered by renewable vitality. That leaves some leftover oxygen to cope with. 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 useless bottoms within the Baltic Sea is among the largest on the earth, with an space nearly twice that of Denmark,” reported the College of Stockholm, which not too long ago issued a examine 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 unimaginable for animals to stay in,” they added.
As described by lead researcher Carl Rolff, till the 1980’s the principle drivers of the issue had been the same old 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 will help cut back the Baltic Sea “oxygen debt.”
OX2 has already spent two years surveying the world with a watch on beginning building round 2030, so there’s 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 reasonably busy. In 2022 the corporate famous that it had a complete challenge portfolio of about 23,864 meawatts within the pipeline, together with two new offshore wind tasks within the Åland space, known as Noatun South and Noatun North.
The numbers are spectacular, however by way of releasing Europe from the Russian fossil vitality internet there’s extra to the story.
“Along with offshore wind farms within the Åland maritime zone, the Noatun tasks additionally embrace a grid answer 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 degree up each its border safety and its renewable vitality 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 challenge, they usually introduced plans to mix the 2 into one tasks.
The 2 companions purpose 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 vitality hub in Europe.”
They’ll have loads of firm. Except for Neptunus, one other large inexperienced hydrogen hub in Europe is deliberate for the Netherlands, with the electrolyzers to be powered by each wind and photo voltaic vitality.
Russia’s LNG loophole can be threatened by Ukraine, which is already planning to deploy its appreciable renewable vitality property to provide Europe with inexperienced hydrogen and 0 emission electrical energy.
Water, Water In every single place
That also leaves some questions on offshore wind energy within the Baltic Sea, and safety is considered one of them.
Russia has a slim fingerhold on the Baltic Sea via Kaliningrad Oblast, so in principle it, too, might get some offshore wind tasks up and working. That’s unlikely, contemplating that Kaliningrad is the headquarters of Russia’s Baltic Fleet.
Wind stakeholders have already raised considerations over indicators that Russia has been scouting the situation of offshore wind generators within the North Sea. It’s a secure guess the identical considerations are at work within the Baltic Sea.
Placing that apart for the second, the opposite query that involves thoughts is water for the electrolysis methods. Earlier iterations of electrolysis know-how required pure water to be able to not gum up the tools, which signifies that seawater poses one thing of a problem.
The US Division of Power has been placing its vitality into growing low-cost pre-treatment methods that allow the usage of seawater, as a near-term answer.
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 fascinating 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 assumed to supply round 1 billion litres a 12 months of wastewater,” the college notes, with Scotland alone contributing about 1 million liters to the full.
“It takes 9kg of water to supply 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 examine, the brand new course of “produced related or barely greater portions of inexperienced hydrogen from the wastewater, in comparison with the outcomes from contemporary water,” the college reported.
You may try the examine below the title, “From brew to wash 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 applied a restricted paywall for some time, but it surely all the time felt fallacious — and it was all the time powerful to resolve what we must always put behind there. In principle, your most unique and finest content material goes behind a paywall. However then fewer folks learn it!! So, we have determined to fully nix paywalls right here at CleanTechnica. However…
