EU working on jet fuel plan as Iran crisis threatens air travel

* EU drafting measures to map refinery capacity, maximise output, draft shows

* Airlines warn of shortages, ​price hikes, disruptions ⁠if Middle East supply stays blocked

* Jet fuel stocks uneven across Europe; ​Spain exports while UK relies on imports

BRUSSELS/LONDON, April 16 (Reuters) - The European Union is drafting plans to tackle a looming jet fuel supply crunch and maximise refinery output, officials ​said.

European ‌airlines have warned of jet fuel shortages within weeks as a result of the Iran war, disrupting travel ahead of summer. Europe is more dependent on jet fuel imports, with ⁠some 75% from the Middle East, than for any other transport fuel. From next month, the ⁠European Commission will introduce EU-wide mapping of refining capacity for ​oil products and introduce measures "to ensure that existing refining capacity is fully utilised and maintained", a draft proposal seen by Reuters said.

The EU is also working on measures targeting jet fuel supply, but those are still in development, officials familiar with the proposals said. The Commission declined to comment on the draft plans, which are due to ​be published on ‌April 22.

Jet fuel prices have soared since the blocking of the Strait of Hormuz and European airlines are warning of price hikes, cancellations and grounded planes if the war does not end soon. U.S. President Donald Trump said in comments aired on Wednesday that the war with Iran could end soon, telling the world to watch out for an "amazing two days", while U.S. forces imposing a blockade turned back vessels leaving Iranian ports.

SHORTAGES COULD HIT SUMMER HOLIDAY SEASON Airlines are preparing for ​a potential supply crunch, with the International Energy Agency forecasting jet fuel shortages by June if the region can only replace half of the supplies it normally gets from ‌the Middle East.

Increased imports from Africa and the U.S. are unlikely to fully make up for the drop, while fuel handling consortia that feed into airports do not always keep long-term stocks, analysts said, and many airports do ‌not keep large stocks on hand. Some airports have warned of shortages within three weeks if the Strait of Hormuz remains closed to fuel shipments.

As domestic oil production has shrunk and governments have sought to shift to cleaner energy sources, Europe's refining capacity has declined in recent years.

The IEA said this month that many ​European refiners are already operating at maximum capacity for jet fuel production.

"Our (jet fuel) suppliers are changing their forecasting windows, and they're no longer keen to give an outlook over a time window ‌that goes beyond one month," Lufthansa CTO, Grazia Vittadini, told Reuters in Frankfurt on Wednesday.

A spokesperson for UK airport Heathrow said that the impacts of the war had not yet hit its operations, although it was monitoring the situation. ADP, owner of Paris Charles de Gaulle, did not respond to a request for comment.

The proposed EU ⁠rules would not ⁠be expected to impact Britain, which is outside the 27-member bloc.

JET FUEL STOCKS VARY AROUND EUROPE Jet fuel ‌supplies are highly uneven across Europe. Spain has eight refineries and is a net exporter of jet fuel, while imports cover more than 60% of British demand. European airlines have asked the EU to ​improve monitoring of jet fuel supplies and consider ​joint purchasing of kerosene.

The OECD Europe region, which includes EU countries as well as others like Britain and ‌Norway, imports more than 30% of its jet fuel, IEA data shows, with most going through the Strait.

The EU requires its members to maintain 90 days of emergency oil reserves as a buffer against supply shocks. This does not include a specific requirement on jet fuel, although countries can count it and other oil products towards their stock.
