Mars is one (already installed) pictures on hydrogen 2020 twitter feed so not sure why not announced
For the other one take you pick:
GM is circulating but I still think Target may be ready to commit for Sussex VA
IKEA USA could be ready given the trial in Europe and plans for 2 huge center in Illinois near the Mars one.
