Innovation for Sustainable Energy Buffer Storage

Background

Selected Design

Our design recommendation for this project is to use seamless steel tanks for the H2 gas buffer system. The main designfactors that we based this decision on was the fact that these tanks are readily available on the market compared to the other options. This is also the most cost efficient option as each tank would cost $260, so our design using four tanks would come out to about $1040 for the tanks. This is extremely cheap compared to our other options that could cost up to $2500 for a single tank.

 

Updated Designc6-4c_pic

We decided to slightly modify our design from a four tank system to a six tanks system. The new design comes with a storage rack set up that address the issue of covering tank manifoldsĀ  for transportation. To meet DOT standards while in transportation tanks manifolds must covered and protected during transportation. Our new six tanks design comes with a storage rack that has a built in protection cover for the manifolds. This is a much greater design because we wont have to worry with the issue of unhooking the connections to the tanks and cover the manifolds each to a transportation is going to take place.

Seamless Steel Tanks: $260 x 4 = $1040

  • Quoted by Oxarc at $260 per tank at 195 cubic feet STP

Tank Frame Materials: $350

  • Bosch tubing and related hardware

Manpower to Assemble: $10/hr*2hr=$20

  • Assembly of tanks and required frames

Total cost for 5 years: $1040+$350+$20 = $1410

Salvage Value after 5 years: $500

Future

The installation of the buffer storage is mostly complete, but there are a few things that will need to be addressed before it’s finished.

  1. An inlet line needs to be added through the container
  2. A regulator and outlet line is needed to plumb the buffer storage tanks in with the rest of the system.
