Presentation Title: The Role of Green Hydrogen in the Race to Zero


Today, the oil & gas industry is faced with the real challenge of reducing their emissions as part of the race to zero. In today’s framework, these challenges can turn into opportunities for the oil & gas sector’s competitive advantages: their energy resources, geographic locations, access to abundant renewable energy and highly developed infrastructure to develop and produce clean hydrogen. This presentation will provide insights into the role of green hydrogen in the race to zero from a global perspective of the oil & gas industry.
