According to this article, BRUA gas pipeline project seems to be on hold after a surprise decision coming from Hungary:
The Hungarian transmission system operator FGSZ took the European gas market by surprise on Friday when it announced it was no longer in a position to hold an open season on the Romanian-Hungarian-Austrian section of the pipeline.
Instead, FGSZ noted, the only ‘economically viable’ part of the Bulgaria-Hungary-Romania-Austria (BRUA) pipeline would be the existing Romania-Hungary interconnector, which could be expanded from its current capacity of 4.4 billion cubic metres (bcm) to 5.26bmc/year.
FGSZ said it had contacted the Romanian grid operator Transgaz with a view to conduct an open season procedure just on this point. The procedure would have an almost identical draft for the Romania-Hungary project only.
Question: Why does Hungary not seem to support anymore the original project? This project should support a less dependent EU on Russian gas.

Russia’s Gazprom may be able to use the existing infrastructure to sell Russian gas to the region.and thatcompanies which expect to export the Black Sea gas, including the US ExxonMobil, or Austria’s OMV could be locked out of regional exports.. However these are not elaborated and thus I came to Politics.SE with this question. – Alexei Aug 17 '17 at 15:50
