1 Introduction

Table 2 gives the energy and momentum properties of the flywheel. For energy storage the intended speed range is 20,000 to 60,000 RPM so the net energy storage is 51.2 W-h. For ACS operation it may be desirable to work down to lower speed and the flywheel can provide operation over the range 10,000 to 60,000 RPM to achieve a net momentum

Can the reaction wheels also be used to store energy?

$begingroup$ As you suggest, you can couple two reaction wheels to store both energy and angular momentum around one axis. Then if you have enough pairs (4 for redundancy) you can store energy and momentum around all three axes. The simple answer to your question is "Yes-you can reuse reaction wheels to do energy and momentum storage."
