When you consider that the hypothesis of dark energy is based on the observation of the recession velocity of distant galaxies it is entirely possible that there is a completely different explanation for these observations.
The motion of any galaxy is affected by the expansion of space and by gravitational acceleration. It is proposed that the unexpected recession velocity of distant galaxies is caused by gravitational acceleration and not dark energy.
Dark energy does not exist.

Let us consider the following approach to dark energy and to dark matter:
(1) The energy density of the gravitational field around matter is negative.
(2) A static field with a negative energy density is unstable and cannot exist.
The contradiction between these two facts can be solved by the existence of a homogenous gravitational field with a positive energy density. If such a field exists, the fields around matter only dig holes into it. But the strength of this field must be stronger than the gravitation at the surface of the largest neutron stars.
The inhomogeneous part of this field, a gravitational field with a positive energy density is the dark energy.
However, there is a relation to dark matter. A gravitational field with a positive energy density provides an efficient wave generation mechanism. Moving particles excite this field. With this mechanism stars become effective volume radiators of incoherent gravitational energy.
The gradient of the radiation density has an antigravitational impact. It leads to a significant underestimation of the mass of stars. The mass of big stars is underestimated to a higher extend.
The essential point is that the antigravitational impact ends if the radiation density has reached the background density. Then the gravitational impact of the real mass appears.
The mass shielded by the antigravitational impact is the dark matter.
