Romania to take control of Lukoil’s assets

Romania wants to take control of Lukoil’s operations to prevent an imminent freeze from the sanctions imposed by the United States. Bulgaria is already putting the Russian company’s refinery, the largest in the Balkans, under a trusteeship. Serbia announced that similar measures have been proposed to exempt Gazprom-owned NIS and its refinery, the only one in the country, from the sanctions.

Minister of Energy of Romania Bogdan Ivan seems to have endorsed neighboring Bulgaria’s approach to the issue of US sanctions against Lukoil. He said the government has to take control of the Russian company’s operations, Profit.ro reported.

The minister didn’t clarify whether it would be a temporary trusteeship. But President Nicușor Dan, who took the helm half a year ago, said there is an option for Romania to assume control for a limited period.

“We protect Romania’s energy security and firmly enforce international sanctions targeting Lukoil. My colleagues in the Ministry of Energy continue to work, together with all relevant authorities, on creating legislation that will ensure, on the one hand, full compliance with the sanctions regime established by the United States, and on the other hand, the continuity of Petrotel Ploiești’s refining activities, as well as the placement of petroleum products, without jeopardizing the supply of the national fuel market,” Ivan stated.

Minister Ivan turns more hawkish regarding sanctions against Russia

The minister claimed he would not request an extension of the November 21 deadline from the US. “Moreover, I will support the replication and uniform application of the sanctions initiated by the US throughout the European Union,” he stressed.

It marks a shift from the stance that the ministry expressed late last month, saying that the EU needs to adopt a position before Romania decides to move. Notably, Ivan held talks on November 8 in Washington with senior US officials, the article notes.

“Romania must take control of the company to guarantee the full implementation of international measures, to protect the jobs of the 5,000 employees and to ensure the stability and security of the national energy system,” Ivan said.

However, the Petrotel Lukoil refinery had 542 employees on average in 2023 and another 203 worked at the company’s gas stations. Altogether, its six firms have a total payroll of under nine hundred, the article notes.

Germany placed Rosneft under state administration in 2022.

Bulgaria, Serbia struggling to keep Russian-owned refineries in operation

Nationalization could backfire because of property rights, though imposing state management is also a complicated matter. Romania earlier signaled that nationalization would be the last option.

Bulgaria has urgently adopted a law facilitating a takeover of Lukoil’s refinery in Burgas, the largest in the region. The state administrator would be authorized to sell it. It is unclear whether the measure could postpone or prevent the sanctions.

President Rumen Radev refused to sign the law and returned it to the National Assembly. It would “undermine the legal order” through “indirect nationalization” and expose public finances to a high risk, he warned.

Oil refiner and service stations operator NIS in Serbia is already under US sanctions. Russian state-owned Gazprom holds a majority stake in the company through two subsidiaries.

Serbian Minister of Mining and Energy Dubravka Đedović Handanović said yesterday that the “Russian owners” sent a request to the US Office of Foreign Assets Control (OFAC) to renew the company’s license due to “negotiations with a third party.”

The government in Belgrade has supported the request, she added. The Russian side is prepared to cede control and influence over NIS to a third party, Đedović Handanović revealed.

According to media speculations, one of the candidates is Hungary-based MOL, given that the country managed to obtain a one-year exemption from the US for Russian oil and gas.

Lukoil is operating in Serbia as well, where it has a chain of fuel stations.

Project pipeline in Greece for CO2 capture, storage nearing EUR 4 billion

Carbon capture and storage projects worth as much as EUR 3.6 billion are under development in Greece. Energean’s subsidiary EnEarth has launched a tender for drilling two wells for the Prinos site under the Aegean Sea, while DESFA won a EUR 169 million EU grant for a carbon dioxide liquefaction unit.

Investors in Greece are counting on demand from the domestic industry for carbon capture and storage (CCS), so that it can remain competitive with regard to carbon dioxide emission costs. Euro2day calculated that the project pipeline is worth up to EUR 3.6 billion as the endeavors are clearing major milestones.

The time for drilling in Prinos is approaching. EnEarth, a subsidiary of Energean, is working on the establishment of the storage facility offshore Kavala. Earlier this month it launched a tender for drilling two wells.

The Prinos project is valued at EUR 1.2 billion

Works are scheduled to begin in the first half of next year. The project is worth EUR 1.2 billion, of which the firm secured EUR 270 million in funding from the European Union. It is waiting for environmental terms (AEPO) from the Ministry of Environment and Energy, as well as for the storage permit.

Notably, a draft law covering the sector is reportedly complete.

DESFA seeks contractor to drill two wells in Prinos

Another step ahead was achieved with a project for a pipeline that would transport CO2 from energy-intensive industrial facilities to a liquefaction system in Revithoussa. The endeavor is called ApolloCO2. Greece’s National Natural Gas System Operator (DESFA) won EUR 169.3 million through the European Union’s Innovation Fund for the terminal.

The system would include temporary storage and transport by ships to permanent storage. The budget amounts to EUR 700 million in the first phase, with another EUR 60 million envisaged for an expansion.

ApolloCO2 is in a group of 61 projects in the Innovation Fund’s latest round for net zero technology, worth EUR 2.9 billion in total.

DESFA is working on the investment with Ecolog, a subsidiary of GasLog.

EU funding three major carbon capture projects that would be connected with Prinos storage site

AppoloCO2 would bring CO2 from three capture facilities also funded by the EU. There is a possibility to involve overseas customers as well.

Cement maker Heracles, part of Holcim Group, is developing the Olympus project worth EUR 400 million in Milaki, Aliveri. Its competitor Titan has a EUR 584 million endeavor underway in Kamari, Boeotia (Viotia). It is called Ifestos.

DESFA has applied for EUR 30 million from Connecting Europe Facility for the CO2 pipeline

Motor Oil Hellas aims to install a unit in its Agioi Theodoroi oil refinery costing EUR 300 million to EUR 400 million. The project is called IRIS – Innovative low caRbon hydrogen and methanol productIon by large Scale carbon capture. It is for the construction and operation of a CCUS and e-methanol production system that would cut the refinery’s CO2 emissions by a quarter. CCUS stands for carbon capture, utilization and storage.

DESFA is seeking EUR 30 million from the EU’s Connecting Europe Facility (CEF) for a 35-kilometer CO2 pipeline. The first part would go from Ifestos and branch out to HELLENiQ Energy’s oil refinery in Elefsina (Eleusis). In subsequent phases, pipelines would reach Heracles’ Olympus, Metlen’s aluminum complex in Aspra Spitia, Thisvi in Boeotia (for GEK Terna’s Heron and HELLENiQ’s subsidiary Elpedison), and eventually Motor Oil’s IRIS.

As capacities grow, larger ships would be required to lower transportation costs. According to the article, three such vessels would cost EUR 240 million overall.

US torpedoes Lukoil’s deal to sell its overseas business to Gunvor

The United States Department of the Treasury said it wouldn’t allow Gunvor to “operate and profit,” calling it “the Kremlin’s puppet.” The energy trader responded that the statement is “fundamentally misinformed and false,” but it withdrew its proposal for Lukoil’s international assets.

For a minute it seemed that a potential fuel crisis in Europe – especially in the southeast – was going to be prevented. Russian oil company Lukoil, which came under US sanctions, agreed late last month to sell its foreign assets to Gunvor Group. The proposed transaction could have become a model for the resolution of sanctions against Serbia-based NIS, which operates the country’s only refinery and the largest chain of service stations.

A comprehensive reshuffling of Russian energy business in Europe apparently depends on peace negotiations for Ukraine with the administration of President Donald Trump. Amid a lack of progress, it scuttled the acquisition.

“President Trump has been clear that the war must end immediately. As long as Putin continues the senseless killings, the Kremlin’s puppet, Gunvor, will never get a license to operate and profit,” the Treasury Department said.

Gunvor scraps Lukoil deal after US threat

Gunvor, one of the largest energy traders in the world, is registered in Cyprus. The company, which operates out of Geneva and several other offices, gave up on the deal.

“The Treasury Department statement about Gunvor is fundamentally misinformed and false. Gunvor is and has always been open and transparent about its ownership and business, and has for more than a decade actively distanced itself from Russia, stopped trading in line with sanctions, sold off Russian assets, and publicly condemned the war in Ukraine. We welcome the opportunity to ensure this clear misunderstanding is corrected. In the meantime, Gunvor withdraws its proposal for Lukoil’s international assets,” the firm said.

Swedish billionaire Torbjörn Törnqvist, Gunvor’s CEO, owns a 85% share

Chief executive officer Torbjörn Törnqvist, a Swedish billionaire, owns 85% of the company. He co-founded it in 2000 with Russian businessman Gennady Timchenko, who sold his stake to his partner in 2014 after coming under US sanctions himself.

Russia reacted to the US Treasury Department’s new accusations by calling the trade restrictions illegal.

Refinery in Romania not attractive for purchase

Lukoil’s facilities up for sale include the largest oil refinery in the Balkans – Lukoil Neftohim Burgas in Bulgaria, as well as the Petrotel-Lukoil refinery in Romania. The Russian company also has fuel retail networks in Romania, Bulgaria, Turkey, North Macedonia, Croatia, Serbia, and Montenegro.

Notably, the refinery in Romania doesn’t seem to be attractive for possible buyers, Profit.ro reported. It is designed for processing the Russian Ural type of oil, rich in sulfur. Adaptation to sweeter crude would require major investments, maybe bigger than for an entirely new refinery, according to the article.

A crucial factor as well is that Lukoil’s businesses abroad were worth an estimated USD 22 billion in 2023, over three times more than Gunvor.

Russia’s Lukoil to sell refineries, fuel chains in Southeast Europe amid US sanctions

Russian oil producer Lukoil said it intends to sell its international assets due to US sanctions and that it has already begun reviewing bids. The company’s foreign subsidiaries include oil refineries in Bulgaria and Romania, as well as fuel retail chains across Southeast Europe.

The sale of Lukoil’s international assets is being carried out under a wind-down license from the United States Office of Foreign Assets Control (OFAC). In a press release, the company said it might apply for an extension of the license, if necessary to ensure uninterrupted operations of its subsidiaries.​

The facilities up for sale include the largest oil refinery in the Balkans – Lukoil Neftohim Burgas in Bulgaria, as well as the Petrotel-Lukoil refinery in Romania. Lukoil also has fuel retail networks in Romania, Bulgaria, Turkey, North Macedonia, Croatia, Serbia, and Montenegro.

Lukoil operates the largest oil refinery in the Balkans and fuel retail chains across the region

Lukoil Neftohim Burgas is a major player in Bulgaria, supplying almost the entire market, according to reports. Its capacity is 190,000 barrels per day. On the other hand, the capacity of Petrotel-Lukoil in Romania is much smaller, at about 2.4 million tons per year.

The Bulgarian parliament has adopted legislative amendments requiring any sale of Lukoil’s assets in Bulgaria to be cleared by the country’s government and intelligence service.

Serbia-based oil company NIS is also under US sanctions, while the EU is imposing a ban on Russian gas

The US sanctions against Russian energy companies, which took effect earlier this month, are also affecting NIS, a Serbia-based oil refiner and fuel retailer owned by Russia’s Gazprom.

At the same time, the European Union plans to ban imports of Russian natural gas starting on January 1, 2026. However, a European Commission spokesperson said that it would not apply to the transit of Russian gas and would not affect deliveries to Serbia and Bosnia and Herzegovina.

Oil trader Gunvor set to take over Lukoil’s refineries, fuel chains in Southeast Europe

Russian oil producer Lukoil has accepted an offer from global commodities trader Gunvor Group Ltd. to acquire its international assets, which were put up for sale due to sanctions imposed by the United States over the war in Ukraine. The assets include oil refineries in Bulgaria and Romania, as well as fuel retail chains across Southeast Europe.

Lukoil has decided not to negotiate with other potential buyers. It will sell 100% of Lukoil International GmbH, which owns its assets outside of Russia, to Gunvor under key terms agreed earlier, according to an announcement from the Russian company. The value of the transaction was not disclosed.

Lukoil will not negotiate with other potential buyers

To conclude a binding agreement, the buyer needs to obtain permission from the US Office of Foreign Assets Control (OFAC), along with other approvals in relevant jurisdictions, Lukoil said.

If necessary, the two companies will apply for an extension of the existing OFAC license to ensure uninterrupted operations of Lukoil’s international assets and their banking servicing until the completion of the transaction, it added.

Gunvor is owned by Swedish billionaire Torbjörn Törnqvist

According to its website, Gunvor is one of the world’s largest independent commodities trading houses by turnover and a leading global oil trader. The company is majority‑owned by Swedish billionaire Torbjörn Törnqvist.

Lukoil’s facilities up for sale include the largest oil refinery in the Balkans – Lukoil Neftohim Burgas in Bulgaria, as well as the Petrotel-Lukoil refinery in Romania. The Russian company also has fuel retail networks in Romania, Bulgaria, Turkey, North Macedonia, Croatia, Serbia, and Montenegro.

The US sanctions targeting Russian energy companies took effect earlier this month.

Several EU member states face uncertainty amid looming Russian gas ban

The European Union’s proposed measures to phase out imports of Russian oil and gas would destroy Hungary’s security of supply, according to Minister of Foreign Affairs and Trade Péter Szijjártó, who spoke at the meeting of energy ministers in Luxembourg. Slovakia is in a similar situation, while Romania pointed to the difficulty of proving the origin of foreign gas.

The draft regulation that the Council of the EU adopted doesn’t explicitly call for a ban on the transit of gas to third countries, while it foresees a temporary suspension for member states in case of supply disruption. The proposal also allows the possibility of importing non-Russian gas through the TurkStream pipeline.

The meeting of the so-called Energy Council highlighted several issues and concerns among EU member states about the proposed ban on Russian natural gas, including liquefied natural gas (LNG). Energy ministers in the Council of the EU adopted their position ahead of negotiations with the European Parliament on measures that they plan to introduce on January 1.

There would be a transition period for existing contracts for Russian fossil gas. Short-term ones concluded before June 17 this year would remain in force until June 17, 2026. Long-term contracts may run until January 1, 2028. It is also the targeted date for ending imports of Russian oil.

Szijjártó: The remaining infrastructure, physically and capacity-wise, is not able to supply Hungary

“The real impact of this regulation is that our safe supply of energy in Hungary is gonna be killed,” the country’s Minister of Foreign Affairs and Trade Péter Szijjártó stressed at the meeting.

He clarified that he wasn’t speaking about prices, and warned of damage from the proposed regulation – in the name of diversification.

“As now we are phasing out supply routes towards Hungary, the remaining infrastructure, physically and capacity-wise, is not able to supply the country. This has nothing to do with politics. This has nothing to do with Russia. This has nothing to do with the war in Ukraine. This is mathematics and physics,” Szijjártó stressed.

He also reiterated that his country would be left dependent on one oil supply route, via Croatia. It would leave Hungary “totally defenseless to a monopoly” as the transit fee doubled since the start of the war and it is five times higher than the current European benchmark, the minister underscored.

Bulgaria asks for protection from arbitration for gas TSOs

Slovak Deputy Prime Minister and Minister of Economy Denisa Saková said the supply of gas to her country is limited. There are interconnections with all neighbors, but external capacity bottlenecks remain, she argued. Bulgaria asked for provisions protecting gas transmission system operators (TSOs) from arbitration and financial penalties.

Romania voted for the draft regulation, but warned that identifying the origin of imported gas would be difficult

Secretary of State in Romania’s Ministry of Energy Cristian Bușoi urged for a workable and harmonized verification system and for the development of clear guidelines.

“This is not a matter of energy policy, but of strategic autonomy and European solidarity. At the same time, as we move from political vision to implementation, we believe it is important that the new authorization and verification system remains practical, transparent and proportionate. The additional requirements to demonstrate the exact country of production represent a new level of responsibility that, while understandable, and we support this in principle, may be difficult to fulfill in practice, particularly for pipeline [and] natural gas traded on hubs, and shipments transport, including LNG cargos that involve multiple sources and blending,” Bușoi told the ministers.

Council of EU proposes suspension clause

Notably, the Energy Council’s position, part of the REPowerEU plan and sanctions against Russia, is that the regulation should contain a suspension clause. The European Commission could temporarily lift the ban on Russian gas and LNG in case of significant disruptions of supply.

Another important element is the possibility of importing non-Russian gas through the TurkStream pipeline if the fuel’s origin is proven.

Gas transit through EU not subject to prohibition

Energy ministers said the EU should ensure that natural gas which crosses the 27-member bloc under a transit procedure is not ultimately entering into free circulation in the union.

It would imply that Serbia, Bosnia and Herzegovina and North Macedonia, non-EU countries, could continue to buy Russian gas that is delivered through Balkan Stream. It is the extension of TurkStream running through Bulgaria and Serbia to Hungary.

“Any gas which, before its import into the EU, was exported from the Russian Federation, either via direct export from Russia to the EU or via indirect export through a third country, should, except in case of transit, be subject to the prohibition”, the document reads.

Serbia still hasn’t signed a long-term gas supply contract with the Russian side, and the previous one expired in May. Moreover, the United States have imposed sanctions on Gazprom-controlled NIS, Serbia’s national oil importer, refiner and operator of a chain of service stations.

On top of it all, hydropower output is at a record low due to chronic drought, while coal is being imported as domestic mines don’t produce enough lignite.

Hungary’s Szijjártó: MOL to supply more oil, fuel to Serbia amid sanctions

Minister of Foreign Affairs and Trade of Hungary Péter Szijjártó said Serbia can count on an increase in supply of oil and fuel from MOL, as NIS is now under US sanctions. However, it cannot fully replace the volume that was coming through Croatia, he warned and stressed that it shows the risk of depending on a single oil pipeline.

The United States has imposed sanctions on Serbian oil refiner and fuel distributor NIS, controlled by Russian Gazprom’s subsidiaries. Except for a small share of domestic production, the company was getting all its oil through the Croatian Jadranski naftovod (JANAF) pipeline. Serbian President Aleksandar Vučić said the country’s only refinery, in Pančevo, can only operate until the end of the month, while that the current stockpiles of derivatives can last until the end of the year.

Hungarian Minister of Foreign Affairs and Trade Péter Szijjártó promised assistance. “Of course, we stand by our Serbian friends. We are in constant contact, and since MOL, as the largest energy company in the region, plays an important role in the supply of crude oil and fuel in Serbia, of course our Serbian friends can also count on MOL’s increased deliveries,” he stated.

Serbia’s only refinery has oil only until the end of the month

At the same time, the Hungarian official acknowledged that it cannot fully replace the volume that was coming via Croatia.

“Therefore, everyone should remember once again as a very important lesson: there are very serious risks in the situation when a country depends on a single oil pipeline, especially if it comes from Croatia,” Szijjártó stressed.

Namely, the government in Budapest has been complaining that JANAF’s oil transport fees were too high and it disputed the Croatian state-owned pipeline operator’s ability to cover the entire needs of MOL’s refineries in Hungary and Slovakia. The company still gets Russian oil through the Druzhba pipeline as well.

According to the Energy Community Secretariat, oil and petroleum product stocks in Serbia in July amounted to 43.8 days of average net imports, compared to the required 90 days.

Šušnjar: Croatia prepared to buy oil company NIS in Serbia

Minister of Economy Ante Šušnjar has said that Croatia is prepared to acquire Russian-owned oil company NIS in Serbia, which came under US sanctions today. Croatian state-owned oil pipeline operator Jadranski naftovod (JANAF) relies heavily on deliveries to NIS, and Šušnjar believes the acquisition would benefit both Croatia and Serbia.

The US sanctions against the Serbia-based oil company took effect after nine months of delays. JANAF stated yesterday that it had a license to continue deliveries to NIS until October 15, but Minister of Economy Ante Šušnjar said today that everything from the terminals and the pipeline had already been transported and that there were no more deliveries to Serbia.

Šušnjar: Croatia’s plan to buy NIS is not aimed at dominating Serbia’s retail market

Asked about plans to buy NIS, Šušnjar said that Croatia is prepared to do so to protect JANAF, whose business has relied on ties with NIS for the past 40 years. He emphasized that there is no intention to dominate Serbia’s retail market.

US sanctions against NIS will affect Croatia, Serbia, and BiH

According to Šušnjar, if Croatia were to take over NIS, it would ease the situation for both Croatia and Serbia. The sanctions also pose an additional challenge for Bosnia and Herzegovina, given that 20% of the country’s oil derivatives market is supplied by NIS’ refinery in Pančevo, he noted.

Business with NIS accounts for more than 30% of JANAF’s revenue, and suspending deliveries until the end of this year alone would cost Croatia around EUR 18 million, according to Stjepan Adanić, chairman of JANAF’s management board.

The US imposed sanctions on Russian state-owned Gazprom Neft, which until recently held a 50% stake in NIS, with its parent company Gazprom controlling a further 6.2%. After a reshuffle, Gazprom Neft now owns 44.9%, and Intelligence, a firm within Gazprom’s system, 11.3% of NIS. Serbia’s stake is 29.9%.

Serbia’s economy in uncharted territory amid imminent US sanctions against oil company NIS

For NIS in Serbia, doing business will become exceptionally difficult from tomorrow, when the United States imposes sanctions, starting with payment systems. The same goes for any enterprise cooperating with the oil refiner and distributor, majority owned by Russia’s Gazprom Neft and another firm controlled by Gazprom.

Nine months after the US announced sanctions against NIS, which were postponed several times, they are coming into force tomorrow morning. Apparently, the American Office of Foreign Assets Control (OFAC) is imposing restrictive measures for Serbia’s national oil importer, refiner and operator of a chain of service stations. Croatian company Jadranski naftovod (JANAF), which depends to a great extent on supplying NIS, said the deliveries can last until October 15.

The US and the United Kingdom announced sanctions early this year against Russian state-owned Gazprom Neft, which at the time held 50% of ownership, while its parent Gazprom controlled another 6.2%. After a reshuffle, Gazprom Neft now has 44.9% of NIS, and Intelligence, a firm within Gazprom’s system, owns 11.3%. Serbia’s stake is 29.9%.

Plan B has numerous unknowns

The oil refinery in Pančevo is the only diesel and gasoline producer in Serbia and it dominates the market by far. According to media reports, NIS has considered switching to cash payments, with the exception of the domestic currency system DinaCard, and transferring all its accounts to the state-owned Postal Savings Bank.

It is unlikely that the company would be able to cover all the logistics and finances that way. At the same time, the entire Serbian economy is at risk, together with basic services for citizens. Organizing fuel imports will take time, which may lead to shortages and price hikes. Officials and the representatives of the oil sector claim that the current stockpiles can last several months.

Forced nationalization may switch energy crisis to gas supply from Russia

Back in January, President of Serbia Aleksandar Vučić immediately estimated that Russia would have to completely and urgently exit ownership. There was no success in the meantime in talks with the Kremlin and Gazprom.

“There is one possibility. If I said: I may seek nationalization of the property tomorrow. That is the last thing i would say, if I had to. I don’t want that,” Vučić stated late last week.

In case of a forced purchase of the Russian stake, the focus would turn to the supply of Russian gas through the Balkan Stream pipeline, an extension of TurkStream. Serbia still hasn’t signed a long-term contract with the Russian side, and the previous one expired in May.

To make matters worse, Bulgaria said it would end the transit of Russian gas, through Balkan Stream, for short-term arrangements. The move is part of the European Union’s measures to end the purchases of Russian fossil fuels. A total halt is scheduled for 2028. If the supply chain isn’t drastically changed, it would heavily impact Hungary, Slovakia and Serbia, together with Bosnia and Herzegovina and North Macedonia.

Investment risk highest for nuclear power, lowest for solar

Nuclear power plants have the highest construction cost overrun and the longest time delays of all energy projects. In the clean energy sector, the worst marks for violation of set construction cost and timelines go to hydrogen, carbon capture and storage as well as gas power plants, according to a study by the Boston University Institute for Global Sustainability.

The average project costs 40% more than expected for construction and takes almost two years longer than planned, the Boston University Institute for Global Sustainability (IGS) said.

Its researchers used an original dataset 50% larger than the ones in previous literature. They examined cost overrun risks for 662 energy infrastructure projects across 83 countries built between 1936 and 2024, covering USD 1.358 trillion in investment and a total capacity of more than 400 GW.

In total, the study evaluated ten types of projects: coal-, oil-, and natural gas–fueled power plants; nuclear reactors; hydropower plants; utility-scale wind farms; utility-scale solar photovoltaic and concentrated solar power (CSP) facilities; high-voltage transmission lines; bioenergy and geothermal power plants; hydrogen production units; and carbon capture and storage (CCS) facilities.

Both hydrogen and CCS projects exhibited significant time and cost overruns

“We found that more than three fifths of the projects experienced cost overruns, with these overruns being particularly prominent in projects exceeding 1,561 MW in capacity. Positively, the escalation rate in cost overruns has been declining since 1976,” reads the study, published in the Energy Research & Social Science journal.

However, the findings show patterns of cost overruns varied by fuel source. Nuclear and fossil thermal projects exhibited higher cost escalation rates over time, whereas solar power projects showed a decline.

Critically, both hydrogen and CCS projects exhibited significant time and cost overruns, casting doubt on their ability to be rapidly scaled up, to address climate change or meet energy and climate policy priorities, the authors underlined.

The average nuclear power plant has a construction cost overrun of 102.5% and ends up costing USD 1.56 billion more than expected, IGS said.

Red flag for efforts to substantially push forward a hydrogen economy

“Worryingly, these findings raise a legitimate red flag concerning efforts to substantially push forward a hydrogen economy,” said Benjamin Sovacool, lead and first author of the study, director of IGS, and professor at Boston University’s Department of Earth and Environment.

In the results, solar energy and electricity grid transmission projects have the best construction track record and that they are often completed ahead of schedule or below expected cost.

Wind farms also performed favorably in the financial risk assessment, according to the study, called ‘Beyond economies of scale: Learning from construction cost overrun risks and time delays in global energy infrastructure projects’.

“Low-carbon sources of energy such as wind and solar not only have huge climatic and energy security benefits, but also financial advantages related to less construction risk and less chance of delays,” Sovacool stated.

For him, it’s further evidence that such technologies have an array of underrated and underappreciated social and economic value.
