Title : Role of green hydrogen in CO2 emission mitigation in oil refining

Abstract:

Green hydrogen can play a key role in the race to zero emissions for many industries. Specifically, it is important to define that green hydrogen is produced from electrolysis of water using excess renewable electricity from solar PV, on-shore, and off-shore wind sources. It is important to note that the updated EU Renewable Energy Directive (RED III) provides green energy targets, including mandates for industry and transport to use an increasing share of green hydrogen. The new directive includes a requirement for industries such as ammonia and chemicals production, oil refining and green steel for at least 42% of their hydrogen use to be renewable by 2030, rising to 60% by 2035. A recent study evaluated the role of green hydrogen for use in the oil refining industry in Finland as a replacement for grey hydrogen, hydrogen produced by reforming natural gas, concluded that green hydrogen could truly make a significant contribution to CO2 emission mitigation in the oil refining industry. This Finnish study evaluated alternative scenarios for wind power procurement and evaluated the price sensitivity of green hydrogen.

Audience Takeaway Notes:

• Definition of Green Hydrogen - produced from excess renewable electricity.
• Impact of the updated EU Renewable Energy Directive (RED III).
• Role of Green Hydrogen in CO2 Emission Mitigation in Oil Refining.
