College Student with Dependent

I am a 24 y/o college student who is unmarried and has no income, I do receive about 20,000 in grants every year that I pay my tuition and living expenses with but none of it is taxable. This is the first year I will have no income as a full time college student and I’m wondering if I can still claim my son and receive his child tax credit or if I will receive $0 in tax credit because I have no income to claim. This is question I have searched for before but have found absolutely no answers for.
