At plants painted with birds and hedgehogs, hot water from deep underground is being channelled to produce energy and heat for thousands of households in Hungary’s third largest city Szeged.
Experts say the project — billed as Europe’s biggest urban heating system overhaul — can serve as a model for other cities across the continent as EU nations scramble to wean themselves off Russian gas after Moscow’s invasion of Ukraine.
“Geothermal energy is local, accessible and renewable so why not use it,” geologist Tamas Medgyes told AFP beside a recently completed well in the middle of a residential neighbourhood.
The city of 160,000 people, located some 170 kilometres (110 miles) south of Budapest, is one of 12 in the landlocked central European country with geothermal district heating.
When the system is fully built out next year, 27 wells and 16 heating plants will push geothermally heated water through 250 kilometres of pipes to heat 27,000 flats and 400 non-residential consumers.
– ‘Blueprint’ –
This will make it Europe’s biggest geothermal urban heating system outside of Iceland.
But unlike in the Icelandic capital, Szeged’s heating systems were built to run on gas.
EU member Hungary covers 65 percent of its oil needs and 80 percent of its gas needs with imports from Russia.
“This housing project was built in the 1980s. Since then we have burnt millions of cubic metres of imported Russian gas to heat cold water in these apartments,” Medgyes said.
But now, “we drilled down and got the hot water beneath our feet,” he said about the project, whose cost of more than 50 million euros ($51 million) is partially covered by EU funds.
He added the project can be a “blueprint” for cities in parts of France, Germany, Italy or Slovakia that are rich in geothermal deposits.
Experts says geothermal energy is an underutilised source of renewable heat in Europe.
“The geothermal urban heating development in Szeged is an easy-to-adopt example in many regions of Europe,” said Ladislaus Rybach, an expert at the Institute of Geophysics in Zurich, Switzerland.
Lajos Kerekes of the Regional Centre of Energy Policy Research told AFP that more than 25 percent of the EU’s population lives in areas suitable for geothermal district heating.
Long before the Ukraine war, Balazs Kobor, director at Szeged heating firm Szetav, began exploring how cities can use geothermal energy and “knocking on doors of decision-makers”.
In 2015, the city municipality appointed him and Medgyes to initiate the integration of renewables into district heating.
“To heat the city annually the firm was burning 30 million cubic metres of gas and producing around 55,000 tonnes of carbon emissions every year,” said Kobor.
“The city itself was its biggest carbon emitter,” he added.
Replacing gas by geothermal energy will slash the city’s greenhouse gas emissions by 60 percent — around 35,000 tonnes — annually, according to Kobor.
If similar small-to-medium-sized cities switched their district heating to geothermal it would be “a major step towards a carbon neutral, sustainable Europe,” he said.
– 2,000 metres below ground –
Surrounded by the Carpathian and Alps mountain ranges, Hungary and especially the area around Szeged forms a basin where 92-93 degree Celsius (198-199 degree Fahrenheit) hot water collects as deep as 2,000 metres (6,600 feet) below ground.
In facilities adjacent to the wells, “heat exchangers” comprising hundreds of metal panels transfer the heat to water in pipeline circuits that serve different neighbourhoods.
The geothermal water itself does not enter the circuits but re-enters the earth through a “reinjection” well nearby, explained Medgyes.
In another neighbourhood, a noisy drill is gradually working its way deeper and deeper into the ground, adding sections of pipe as it goes.
The drilling period takes around three months, said Medgyes.
And while residents can see and hear the drills as they work, after the work is done, they don’t notice the change of heat source in their homes.
“The radiators and tap water are as warm as before. I don’t feel any difference,” Gabriella Maar Pallo, a 50-year-old clerk, told AFP in her nearby apartment.
US regulators clear Boeing to resume 787 deliveries
After more than a year, aviation giant Boeing will be allowed to resume deliveries of its 787 Dreamliner aircraft “in the coming days,” after the company made changes to its manufacturing process, US air safety regulators announced Monday.
Deliveries of the top-selling widebody plane have been halted since spring 2021, so the news will be welcomed by US airlines and travelers who have suffered from massive delays and canceled flights in recent weeks, partly due to the shortage of aircraft.
“Boeing has made the necessary changes to ensure that the 787 Dreamliner meets all certification standards,” the Federal Aviation Administration said in a statement.
The plane’s travails date to late summer 2020, when the company uncovered manufacturing flaws with some jets. Boeing subsequently identified additional issues, including with the horizontal stabilizer.
The difficulties curtailed deliveries between November 2020 and March 2021. Boeing suspended deliveries later in spring 2021 after more problems surfaced.
Acting FAA Administrator Billy Nolen met with safety inspectors in South Carolina last week to confirm they were satisfied with the company’s improvements, which were made to ensure they comply with standards and to identify potential risks after defects were uncovered on the plane.
“The FAA will inspect each aircraft before an airworthiness certificate is issued and cleared for delivery,” the statement said. “We expect deliveries to resume in the coming days.”
– Cleared for takeoff –
A company spokesman told AFP that Boeing will “continue to work transparently with the FAA and our customers toward resuming 787 deliveries,” but did not confirm the firm had received final FAA approval.
During a July 27 earnings conference call, Chief Executive Dave Calhoun described the company was “on the verge” of garnering approval, though he declined to give a precise target date.
At the end of June, Boeing had 120 Dreamliner planes in inventory and was producing the jet “at very low rates,” the company said in a filing.
The company’s stock price gained ground on the news, closing 0.5 percent higher.
Inability to deliver the Dreamliner has dragged down Boeing’s profits, which plunged 67 percent in the second quarter. And the manufacturing changes have led to billions in additional costs for the company.
The firm has delivered just over 1,000 of the planes since it was first introduced in 2004.
The enhanced regulatory scrutiny of the 787 and other Boeing planes comes on the heels of a pair of crashes in 2018 and 2019 on the 737 MAX, which led to aircraft being banned from the skies globally for more than a year.
But the MAX has since returned to service, enabling Boeing to ramp up production of the planes, collect meaningful revenues and announce significant new orders at the Farnborough Airshow earlier this month.
Even so, Boeing’s backlog of orders in the pipeline lags behind that of archrival Airbus.
No recession in Switzerland this year: chief economist
Switzerland does not expect to dip into recession this year despite the threat of an energy supply squeeze, the government’s chief economist said Sunday.
The Swiss economy is “doing well” despite the impact of the war in Ukraine on energy prices, Eric Scheidegger told the SonntagsZeitung newspaper.
He said it was down to companies to steel themselves for the possibility of power shortages in the winter months.
“We may have to revise our economic forecast downwards for next year. The revised forecast will be published on September 20. However, we do not expect a recession for this year,” Scheidegger said.
“We run the risk of an energy supply bottleneck in winter. If there are persistent production interruptions in the EU and we ourselves have a gas shortage, it becomes problematic.
“In our negative scenario, we expect zero growth for 2023 instead of growth of almost two percent.”
Despite the threat of power shortages and the effects of the war in Ukraine, Scheidegger does not see a serious economic crisis heading towards Switzerland.
“At present, the economy is still doing well. Current indicators show that the economy in this country also developed well in the second quarter — after the outbreak of the war in Ukraine,” he said.
“Economic support measures such as general perks or tax relief are currently therefore neither necessary nor helpful,” he added.
– ‘Foreseeable events’ –
Scheidegger said the Swiss economy was less susceptible to high energy prices than other European countries as gas accounted for only five percent of its total energy consumption.
He said the government would discuss possible measures to curb high energy prices in the coming weeks, which could involve reducing health insurance premiums for low-income households.
The State Secretariat for Economic Affairs official said the help for businesses during the Covid-19 pandemic could not become the norm during economic downturns.
“It’s been known since spring that there can be a power shortage in winter. Companies have time to prepare for this,” he said.
“Companies can, and must, take this operational risk into account… it is up to companies to prepare for foreseeable events.”
As for inflation, he said Switzerland was “an island of bliss” compared to the United States, and inflation was likely to fall before the end of the year.
“At 3.4 percent, inflation is much lower here than in other countries. Core inflation — inflation excluding fresh food, energy and fuel — is at two percent,” he said.
Markets struggle as strong US jobs boost Fed rate hike bets
Asian markets struggled Monday and the dollar held big gains as a blockbuster US jobs report ramped up bets that the Federal Reserve will announce more sharp interest rate hikes as it tries to tame runaway inflation.
While the employment reading — which was more than twice as high as expected — indicated the world’s top economy remained resilient despite rising prices and borrowing costs, it will complicate the bank’s plans to tighten monetary policy.
Traders have hoped that with several indicators pointing to a slowdown, including GDP figures showing a technical recession, policymakers could begin to ease back on their pace of rate hikes.
Now, speculation is growing that the Fed will have to announce a third successive 75 basis-point increase next month, particularly as officials have said their decisions will be data-dependent.
“Friday’s payroll report indicates an overheated labour market that continues to tighten further,” said SPI Asset Management’s Stephen Innes.
“Hence at minimum, the markets expect another 100 basis points of Fed funds rate increases over the next three meetings… with risks skewed towards significant increases.”
All eyes are now on the release this week of US July inflation data, which is expected to show a slight slowdown from June but still at four-decade highs.
The “report seems very unlikely to offer ‘compelling evidence’ of a slowdown needed for the Fed to pull away from its aggressive inflation-fighting mode.” Innes added.
The jobs figures left Wall Street’s main indexes mixed Friday, and Asia followed suit with markets fluctuating in early trade.
However, there was some relief that tensions had calmed since Nancy Pelosi’s visit to Taiwan last week sparked a furious reaction from China that saw it conduct days of live-fire military drills around the island.
Hong Kong dipped along with Sydney, Seoul, Singapore, Taipei, Manila, Jakarta and Wellington.
Tokyo edged up and Shanghai was flat, with better-than-expected Chinese trade data offset by fresh worries about Covid lockdowns in the country that threaten the economic recovery.
The prospect of higher interest rates sent the dollar surging, and it held on to those gains in Asia.
Bets on a recession across leading economies continued to weigh on oil prices as investors worry about the impact on demand — figures last week indicated Americans were driving less now than in summer 2020 at the height of the pandemic.
A rise in US stockpiles was partly responsible for a 10 percent drop in the commodity last week, pushing WTI below $90 for the first time since February.
Both main contracts have lost all the gains seen in the wake of Vladimir Putin’s invasion of Ukraine, which led the United States and Europe to ban imports of Russian crude, hammering already thin supplies.
