Herbert Smith has boosted its profile in the Middle East after advising Hydrogen Energy – a joint venture between BP and Rio Tinto – on a deal that paves the way for the construction of a 'clean' power complex in Abu Dhabi, worth at least $2bn (£1bn).

The agreement between Hydrogen Energy and the Abu Dhabi-based Mubadala Development Company was reached earlier this week, with Herbert Smith fielding a team under City-based partners Andrew Newbery (project finance) and John Geraghty (corporate).

Herbert Smith, whose team also included associates Simon Tysoe and Jacqueline Knox, landed the role thanks to its existing relationship with BP. The mandate comes with the top 10 City law firm set to launch in the emirate in February, adding to a Middle East presence that already includes an office in Dubai.

Magic circle giant Allen & Overy – which launched in Abu Dhabi last year after hiring a team from rival City firm Simmons & Simmons – represented Mubadala on the deal. Abu Dhabi-based projects partner Jaspal Gillar led the firm's team.

The project will see clean hydrogen-based fuel created from natural gas, with carbon dioxide emissions captured and stored rather than being released into the atmosphere.

Geraghty commented: "We are very pleased to have played a role in this groundbreaking deal in the Middle East, where we are continuing to expand. It builds on the relationship we have developed with Hydrogen Energy and further enhances our market-leading position in advising on 'clean' energy projects."
