President Obama’s plan for a $2 billion Energy Security Trust is collecting dust on Capitol Hill.

Obama’s proposal, which he made in this year’s State of the Union address, called for using offshore drilling revenue to pay for research into alternative fuel and vehicles.

But the plan would not have authorized new energy exploration in the oceans, disappointing GOP lawmakers who pushed for allowing drilling off the Atlantic and Pacific coasts.

Republican lawmakers with influence on energy said they’ve yet to hear from the administration about the trust fund plan.

“We haven’t heard much about it, have we? I’ve been waiting for the call,” Sen. Lisa Murkowski (R-Alaska), the top Republican on the Senate Energy and Natural Resources Committee, recently told The Hill.
