HO nervous about home birth - how to reassure him?

Hi ladies, I am looking to hear from those of you whl have experienced or are chosing to give birth at home. My husband is a bit nervous about the idea and says he would rather be at the hospital "in case something goes wrong". I really want to give birth at home for several reasons and know how important his support is. Him being comfortable and fully engaged is really key to this and I was wondering if you can share some tips on what to say to make him feel more comfortable. We will meet the midwife in 3 weeks, he can ask all questions then too but maybe there is something else I can do?
