Petroleum and Other Minerals Development (Amendment) (Climate Emergency Measures) Bill 2018: Discussion (Resumed)

11:00 am

Mr. Brendan Murphy:

On the question about carbon capture and storage, CCS, the Intergovernmental Panel on Climate Change, IPCC, has talked about that being essential to mitigate our emissions. It says the cost of meeting decarbonisation is 138% higher without CCS. I wonder about the potential to reduce emissions from gas via CCS, which we think is very viable for Ireland. Mr. Paul Allen mentioned hydrogen. We are looking at the idea of hydrogen and can see the benefit of it. In the work we have done so far, the cost of producing hydrogen by splitting natural gas and storing the CO2 is much lower than the cost of generating hydrogen from electrolysis. There is merit in it but the question is which is the cheapest.
