Questions:

Question 1 Is there any legislation with regard to safety requirements related to end-user equipment (e.g.: limits in terms of H2 for use in gas appliances)? If yes, please answer the following question.
Not applicable.
Question 2 Changes to gas supply composition may have implications for the design of gas appliances (safety) and the relevant legislation. What are the implications you expect with regard to the possible concentrations of hydrogen in the H2NG blend?
Not applicable.
Question 3 For which end user applications do you foresee the main consequences and at which level? Could you please provide references to underpin your opinion?
Not applicable.
Question 4 Changes to gas supply composition may have implications for CNG compression, storage, and use in CNG vehicles. What are the additional safety precautions needed? Could you please provide references to underpin your opinion
Not applicable.
