24VDC is 24VDC. You can get it with 16 AA or 2 12V drill batteries in series. You only need to make sure the power source can provide the current required by the solenoid.
Here's an
example I found. Substitute the 230V with any voltage you need to drive the switched circuit. Note the relays have a maximum current and voltage rating and will work with voltages and currents in that range. Hopefully that helps understand the wiring using a relay. You can Google how to use a transistor as well.
You have also not answered the question whether you have a transistor or relay to trigger the solenoid on the 24V circuit. The shield you identified is for PWM DC motor control using the L298. Are you running it at 100% duty cycle in your code?
