Clean Hydrogen

Decarbonising the economy with electrofuels

Clean hydrogen has the potential to be a key part of the global effort to implement the Paris Agreement. If current challenges to price, scale and transport are overcome, clean hydrogen will change the way we generate, store, transport and consume energy, as well as replace fossil fuel-based feedstocks in certain industrial processes. In doing so, it will help the world decarbonise 50% percent of the economy that green electric power cannot reach.

We are working with clients to identify and overcome the initial challenges posed in the creation of the clean hydrogen ecosystem and to take from "PowerPoint to reality" transactions in the upstream, midstream and downstream sectors of the nascent green hydrogen value chain.

Recent client highlights

  • H2OK, Oklahoma: advised Woodside Energy in the development of the H2OK Hydrogen Project located in Oklahoma. The project is expected to produce up to 60 tonnes per day of liquid hydrogen. Power for the project will be sourced from the Oklahoma gas and electric grid a large portion of which is wind-power, and Renewable Energy Certificates will be used to abate any remaining emissions.*
  • Hy2Gen, Germany: advised Technip Energies NV, a leading Engineering & Technology company for the energy transition listed at Euronext Paris, as strategic investor on the successful participation in a EUR 200 million investment round for Hy2gen AG, the green hydrogen investment platform based in Wiesbaden, Germany.

* Matters completed by Jonathan Castelan at a previous firm.


  • Early stage hydrogen project, Australia: Advised a fund in relation to an early stage hydrogen project in the Northern Territory of Australia.
  • Electrolyser JV, Europe: Advised a global supplier of industrial and specialty gases for the creation of a joint venture with a contractor/supplier for the development, production and sale of electrolysers on gigawatt scale in the EU.
  • Green Hydrogen, North Africa: Advised a solar power developer/investor in the project development and financing of the production of green hydrogen in a North African country via a hybrid (wind/solar) power solution for the production of green ammonia to be used both as a feedstock in local fertiliser production and for export.
