What is MidCat?
Initially launched in 2003, the 190-kilometre (120-mile) Midi-Catalonia (MidCat) pipeline would pump gas across the Pyrenees from Hostalric just north of Barcelona to Barbaira in southern France.
Its aim was to transport gas from Algeria through Spain to the rest of the European Union. There are currently only two small gas pipelines linking Spain and France.
But following several years of work, the project was abandoned in 2019 after energy regulators from both countries rejected it amid questions over its environmental impact and profitability.
Why restart it?
Since Russia invaded Ukraine in February, the EU has vowed to end its dependence on gas from Russia, which currently supplies nearly 40 percent of the bloc’s gas needs.
A 750-kilometre deepwater pipeline called Medgaz already links gas-rich Algeria with southern Spain.
A second underwater pipeline, called GME links Spain to Algeria via Morocco but Algiers in November shut supply through it due to a diplomatic conflict with Rabat.
Spain also has six terminals for regasifying and storing liquefied natural gas (LNG) transported by sea, the largest network in Europe.
Gas which arrives in Spain by sea and pipeline from Algeria could then be sent on to the rest of Europe though MidCat.
The MidCat pipeline is “crucial” to reduce the EU’s reliance on fossil fuels and “end the Kremlin’s blackmail”, EU commission chief Ursula von der Leyen said Friday in Barcelona in a reference to Russia’s threats to halt its gas supplies to the bloc.
What are the obstacles?
The MidCat pipeline faces several hurdles, starting with its huge price tag estimated in 2018 at €440 million ($460 million). It would also take three to four years to complete.
“MidCat cannot be approached as a short-term solution,” France’s ambassador to Spain, Jean-Michel Casa, said during an interview with Barcelona-based daily newspaper La Vanguadia in March.
In addition, there is a lack of connections between France and Germany, the country which is most interested in finding alternatives to Russian gas.
It would be “much simpler to bring gas directly by boat to Germany,” said Thierry Bros, an energy expert at the Science Po university in Paris.
“This would of course require building gas terminals in Germany” but their cost would not be higher than building MidCat, he told AFP.
How much support does MidCat have?
Despite the debate over its usefulness, MidCat enjoys significant support, especially in Spain where the authorities are pushing for Brussels to declare the project to be of “community interest”.
France has so far been more reserved but according to Madrid this position is changing.
There is a new “perception of the risks and opportunities” that MidCat brings, Spanish Energy Minister Teresa Ribera said, adding Paris “has understood” that Midcat “must” be built.
There are also questions over the financing for the project.
Madrid argues Brussels should foot the bill, not Spanish taxpayers, because the project would benefit the entire EU.
But the European commission has not yet committed to funding it.
Spain also wants the pipeline to be compatible with the transport of green hydrogen, in the hopes this will boost its appeal to Brussels which has made financing renewable energy projects a priority.
