In this review, we discuss the thermoelectric properties in nodal-point semimetals with two bands. For the two-dimensional (2D) case, we show that the expressions of the thermoelectric coefficients take different values depending on the nature of the scattering mechanism responsible for transport, by considering examples of short-ranged disorder potential and screened charged impurities. An anisotropy in the energy dispersion spectrum invariably affects the thermopower quite significantly, as illustrated by the results for a node of semi-Dirac semimetal and a single valley of graphene. We also consider the scenario when a magnetic field of magnitude $B$ is applied perpendicular to the plane of the 2D semimetal. The computations for three-dimensional (3D) cases necessarily involve the inclusion of nontrivial Berry phase effects. In addition to demonstrating the expressions for the response tensors, we discuss the exotic behaviour observed in planar Hall and planar thermal Hall set-ups.
