After contacting Eric Korpela with SETI@home, they now accept Gridcoin as a donation method.
I confirmed the address on the blockchain with a transaction.

I am awaiting confirmation from them that they can see it in their wallet and that the wallet is operational.
I will update this post when I hear back.
Please wait to donate until I have confirmed that they have access to the wallet.
Edit: Wallet is confirmed
