Siemens Gamesa turmoil, main offshore wind challenge pullouts and a Greta Thunberg protest towards wind generators supplied a few of this yr’s best-read Recharge articles, together with battery breakthroughs and additional guarantees of near-limitless energy from nuclear fusion.
It has to say the least been a bruising yr for the wind trade, particularly with regards to Western offshore developments, with provide chain points and spiralling inflation wreaking havoc in tasks.
European turbine makers additionally had a yr to overlook, suffering from profitability and reliability points and looking out over their shoulders at cheaper and ever extra highly effective Chinese language fashions on provide.
Nevertheless it was Spanish-German turbine maker Siemens Gamesa that stole the best-read headlines when it got here to issues going spectacularly mistaken in 2023 – not even together with its payout to an engineer whose arm was ‘guillotined’ by considered one of its generators.
Shocked Siemens Gamesa CEO Eickholt: ‘Issues a lot worse than I assumed potential’
Siemens Gamesa shocked the wind trade – and even its personal CEO Jochen Eickholt – when the results of a technical evaluation of generators was so dangerous that its mum or dad firm Siemens Vitality was compelled to scrap its 2023 forecast.

“The results of the present evaluation will probably be a lot worse than even I’d have thought potential,” Eickholt mentioned in June.
“I’ve mentioned on a number of events that at Siemens Gamesa there’s nothing I’ve not witnessed elsewhere. I’d not repeat that right now,” he mentioned, including that the turbine maker had contrived to supply “new types of failures.”
Siemens Gamesa chief: ‘We offered wind generators that weren’t sufficiently examined’
A couple of months later, Eickholt was again with the admission that Siemens Gamesa had offered generators that “had not been sufficiently examined.”
As Eickholt put it: “Right here, we see, should you like, that we’re roughly the sufferer of our personal ambitions.”
Turbine makers in Europe have additionally confronted wider issues, not least the spectre of Chinese language competitors, which put paid to the continent’s photo voltaic sector within the 2010s.
Jürgen Zeschky, CEO of fellow German turbine maker Enercon, was considered one of many to ring the alarm bell that low-cost Chinese language generators are threatening to blow away one of the best that Europe has to supply.
After a yr of handwringing – interspersed with complaints that Chinese language and American generators are being unfairly subsidised – the EU wind trade has rallied with a European Wind Constitution to assist save its embattled sector.
The rated energy “arms race” between turbine makers has additionally been a supply of accelerating competition and debate within the trade this yr.
Anders Nielsen, chief expertise officer at Vestas, advised Recharge in Might that it was time for a pause on measurement – with the Danish turbine maker pleased to consolidate round its 15MW offshore flagship, which was licensed this month.
That strategy will probably be welcomed by many within the provide chain and wider trade, however the resolve of producers in favour of a pause will undoubtedly be examined by those that aren’t – notably Chinese language turbine makers who at the moment are pushing 20MW and past.
Vattenfall despatched shockwaves across the sector this yr when it halted its 1.4GW Norfolk Boreas challenge citing a “excellent storm” of price will increase engulfing the trade.
Recharge requested whether or not this may be the “first domino to fall” within the nation’s internet zero plans. Definitely it was not the final of the dangerous information.
Finally, Vattenfall offered its complete 4.2GW East Anglia portfolio to Germany’s RWE in a deal that values the tasks at $1.2bn and is among the largest in offshore wind historical past.
However as one analyst warned Recharge in its piece on the challenge pullout, “if Vattenfall are struggling to make the sums work then others are more likely to be in an analogous place.”
Orsted scraps large US offshore wind tasks and takes $4bn hit
So it proved just some months later, when Danish large Orsted scrapped two of America’s largest wind farm tasks – and took a $4bn hit within the course of.
Persevering with provide chain turmoil, excessive rates of interest and allowing delays have been cited as the explanations for the cancellation of the 1.1GW Ocean Wind 1 and 1.15GW Ocean Wind 2 tasks deliberate off the New Jersey coast.
The debacle provoked each rage and glee within the US, whereas Orsted’s chief monetary officer Daniel Lerup and its chief working officer Richard Hunter have been fast to exit the corporate.
Greta Thunberg joins new protest towards wind farm as inexperienced energy large Statkraft blockaded
Local weather activist Greta Thunberg flying in to demand the partial demolition of considered one of Europe’s largest onshore wind tasks supplied one of many yr’s most eye-catching moments.
Thunberg discovered time to go to Oslo twice in 2023 to affix protests towards Statkraft’s 1GW Fosen Vind challenge – undeterred by being detained the primary time.
The challenge was earlier discovered to be based mostly on invalid permits that violated the human rights of the indigenous Sami neighborhood, which complained that two farms that type a part of it are scaring away the reindeer they herd.
Statkraft and its minority companions in one of many offending wind farms not too long ago agreed to pay hundreds of thousands to the reindeer herders in compensation, though a dispute over one other website rumbles on.
‘100,000 years of energy’ | US-Japan workforce hails H2-boron plasma fusion breakthrough
Away from the wind sector, there have been a collection of thrilling headlines within the nuclear fusion trade this yr.
Probably the most eye-catching for our readers was the information that fusion tech that makes use of no radioactive supplies and is calculated to be able to “powering the planet for greater than 100,000 years” had been efficiently piloted.
US scientists have in the meantime achieved the landmark feat of reaching internet vitality achieve from a nuclear fusion response, whereas there may be elevated bullishness concerning the prospect of getting commercial-scale fusion on-line by the top of the last decade.
Within the vitality storage trade, lithium-ion batteries might reign supreme, however there stays enormous curiosity in revolutionary options that imagine they need to have a spot within the inexperienced vitality ecosystem.
Peak Vitality, a US start-up that includes two Tesla veterans, attracted consideration with its declare that its sodium-ion batteries might halve the price of vitality storage and are safer than their lithium-ion counterparts.
A sodium-based battery would additionally calm issues that the lithium-ion provide chain has been cornered by China, a main concern in Europe notably after its current traumatic expertise of going chilly turkey on Russian gasoline.
Breakthrough for brand new battery that boasts 5 instances the ability of lithium-ion
Australian researchers in the meantime claimed to have made a breakthrough in creating revolutionary lithium-sulphur batteries that may maintain as much as 5 instances the vitality of lithium-ion.
The workforce at Monash College in Melbourne mentioned their “nanoporous polymer-coated lithium foil anode” has solved a long-standing difficulty with lithium-sulphur batteries that was inflicting them to die too quickly.
In addition they declare their batteries can be half the worth of lithium-ion, whose sellers will probably be trying over their shoulders if this turbo-charged system ever makes it to market.
