The combustion of methanol to form products of H2O and CO2 do not have as much of an energy change compared to methane and a result methanol releases less energy compared to methane.
The more negative an enthalpy change is, the more heat it is going to release.
The standard enthalpy of combustion for methane is -890 kJ/mol.
Methanol and methane are both simple organic compounds, but they have distinct differences in their chemical properties and uses. Methanol is a liquid alcohol with a chemical formula CH3OH, while methane is a gas with a chemical formula CH4. Methanol is commonly used as a solvent, fuel, and antifreeze, while methane is primarily used as a fuel for heating and electricity generation. Methanol is toxic if ingested, while methane is not toxic but can be flammable. Overall, methanol and methane have different chemical properties and applications despite their similar molecular structures.
The enthalpy of combustion is determined by calorimetry.
One example of a chemical equation that includes the enthalpy change is the combustion of methane: CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) ΔH = -802.3 kJ. In this reaction, 802.3 kJ of heat is released as the products are formed.
Pure methane is odorless.Pure methane when burned produces carbon dioxide, carbon monoxide, and water, all of which are odorless.However the methane available is not pure but has odorants added (e.g. methyl mercaptan) which give it a sulfur like smell and may in some cases pass that smell to the products of combustion.

... will also result in formation of carbon monoxide, formaldehyde (methanal), methanol, carbon black.
Methanol has the highest boiling point among methane, chloromethane, and methanol. This is because methanol has stronger intermolecular forces (hydrogen bonding) compared to methane (only dispersion forces) and chloromethane (dipole-dipole forces).

Methanol has a much higher boiling point than methane due to hydrogen bonding. In methanol, the presence of an -OH (hydroxyl) group allows for strong intermolecular hydrogen bonds between methanol molecules, whereas methane only exhibits weaker van der Waals forces. These hydrogen bonds require more energy to break, resulting in a higher boiling point for methanol compared to methane.

Incomplete combustion of Methane is....2CH4 + 2O2 --> CO + C + 4H2O
"Methane hydroxide" is not standard nomenclature. "Methanol" is the closest genuine compound I can imagine; the formula for that can be written as H3COH.

I am not aware of a process that can convert these compounds into methane. However I have read of an article where developement of a solar cell that generates electricity through some mechanism of reacting carbon dioxide and water to generate methanol. It may not be methane but methanol in of itself is also valuable as a fuel and to generate electricity through a byproduct is just astounding.
