I need help on how to save this photo.

An amazing scene! Was this shot as a jpeg? There is alot of banding and chromatic aberration in the sky and clouds.

Silver Efex Pro would be a good thought....scroll through all the presets and if get close to what you want then tweak the sliders from there.

In photoshop you can use a curves adjustment to increase contrast. Also a selective color adjustment by increasing the black slider in the neutrals might help too.

If you have a RAW image it will be best to start with it rather than a jpeg.

Not sure what you are using to process. Many applications allow you to adjust the conversion to B&W from the 3 individual colour channels. Always easier to do if starting with RAW file. JPEG processing is frequently more limited in post-processing.
