By Rachael Gormley Of DOW JONES NEWSWIRES LONDON (Dow Jones)--Professional recruitment business Hydrogen Group PLC (HYDG.LN) is looking to enter potentially lucrative new markets in Europe and the Middle East, Executive Chairman Ian Temple said Thursday, but it isn't likely to open another international office this year. Temple said the firm has set up teams in London to look to break into economies like Germany and the Benelux region, as well as the Middle East, as it looks to increase overseas revenue. "We really want to hit the ground running," he said. "We expect to open a couple of international offices next year." Hydrogen said Thursday the percentage of its group net fee income from its international increased to around 35% in the first half of 2010 from 19% in the same period a year earlier. -By Rachael Gormley, Dow Jones Newswires; 44-20-7842-9308; rachael.gormley@dowjones.com (END) Dow Jones Newswires July 01, 2010 07:00 ET (11:00 GMT)
