In recent years there has been an advent of quanto options in energy markets. The structure of the payoff is rather a different type from other markets since it is written as a product of an underlying energy index and a measure of temperature. In the HJM framework, by adopting the futures energy dynamics, we use the Malliavin calculus to derive the delta and the cross-gamma expectation formulas. This work can be viewed as an extension of the work done, for example by Benth et al. [1].
