The hydrogen economy is being created, block by block. At Mayer Brown, we are advising the creators on transactions involving everything from upstream hydrogen production to downstream hydrogen usage in refined products such as e-fuels.

It is a dynamic time for the sector with substantial rewards for those who achieve first-mover advantage. Our global hydrogen team has a strong track record of bringing clients’ innovative hydrogen transactions to a successful outcome by applying experience and knowledge gained over decades of advising on energy transactions worldwide and working as executives within energy companies. For example, we have team members who have helped to operate a hydrogen unit in a large refinery prior to becoming a lawyers, as well as others who have served as in-house counsel to leading international energy companies.

We are entrepreneurial, enthusiastic and solutions-oriented, all of which are qualities needed to help our clients build out the hydrogen economy.

One of the best international energy practices in the market, Mayer Brown is strong in every region around the world
