The UK company, chaired by Genel Energy chief executive Tony Hayward, said it had received the investment from a “consortium of investors”, which it did not name.

CompactGTL signed a preliminary agreement in March to develop the plant in Kazakhstan, saying at the time it intended to rope in Kazakhstani investors to finance design and construction of the proposed facility.

It is envisaged that the plant would convert 820,000 cubic metres per day of associated gas into about 3000 barrels per day of diesel fuel and monetise more than 300 million cubic metres of gas annually.
