Ukraine, EU discuss energy hub to dilute Moscow's gas power
* Since late last year, limited EU imports to Ukraine
* Slovakia also working on reverse flow technology
* Ukraine seeking to increase gas storage to 50 bcm
BRUSSELS, May 3 (Reuters) - Ukraine is working to become an energy hub, producing its own gas, developing storage and importing from both the European Union and Russia, Ukraine's visiting energy minister said.
The European Union is pressing for agreements to be sealed with Ukraine by the end of this year as both parties seek to dilute Russia's dominance as a gas supplier.
But Kiev is torn between EU cooperation and Russia's promise to cut its gas bills in return for control of its pipelines.
At the end of April, Ukraine's government asked parliament to lift a ban on the privatisation of state energy firm Naftogaz, which includes pipelines that pump Russian gas to Europe. That could allow Kiev to sell or lease them to Russia's gas export monopoly Gazprom.
Ukraine's Energy Minister Eduard Stavytsky and EU Energy Commissioner Guenther Oettinger raised the possibility of a three-way relationship at talks in Brussels on Friday.
"Ukraine is really trying to consider its geopolitical situation and to establish a gas hub, so we will be able to do spot purchases in central Europe," Stavytsky told reporters.
Guenther Oettinger said he believed EU firms were willing to buy into Ukraine infrastructure. He did not name potential investors, but energy firms were at the closed-door talks, including ExxonMobil and Royal Dutch Shell. None was immediately available to comment.
Stavytsky said $550 million was needed to modernise Ukraine's infrastructure, of which Naftogaz could provide $240 million, while the rest would come from loans.
Since late last year, technology allowing pipeline flows to be reversed has allowed Ukraine to import some gas from EU nations, including Hungary and from Germany via Poland. In addition, Slovakia is seeking to develop reverse flow technology, with a test expected this month, Oettinger said.
As the European Commission seeks to expand its internal energy market, it has also been working to develop Ukraine's extensive gas storage, which could ease any supply shortages.
Ukraine already has storage of 31 billion cubic metres (bcm) and Stavytsky said it was seeking to increase it to 50 bcm, compared with 95 bcm for the European Union as a whole.
In the past, gas flows to the European Union have been disrupted because of Ukraine's quarrels with Russia over how much it has to pay for its supplies.
The European Union depends on Russia for about a quarter of its gas, more than 60 percent of which passes through Ukraine.
All parties are seeking to broaden their options and Russia has built pipelines to bypass Ukraine.
It wants Ukraine to join its Customs Union, while Ukraine and the European Union are debating a free trade and political association deal.
Theoretically, it is to be signed later this year, but the European Union said it is conditional on improved human rights and addressing "politically motivated convictions," a reference to the jailing of former Prime Minister Yulia Tymoshenko, President Viktor Yanukovich's arch rival.
