Methane Pyrolysis – a potential new process for hydrogen ...

1 Methane Pyrolysis a potential new process for hydrogen production without CO2emissionARPA-E Methane Pyrolysis Annual Program Review Virtual Meeting Jan 12&14, 2021Dr. Andreas BodeBASF SE, Carbon Management R&D Dieter FlickBASF SE, Methane pyrolysis12 BASF We create chemistry Our chemistry is used in almost all industries. We combine economic success, social responsibility and environmental protection. Sales 2019: billion EBIT before special items 2019: billion Employees (as of December 31, 2019): 117,628 6 Verbund sites and 361 other production sites Around 100,000 customers from various sectors in almost every country in the world3 Our target: CO2-neutral1growth until 20301 BASF operations excluding the discontinued oil and gas business.
