generation capacity had surpassed 372 GW
globally, with solar and wind accounting for 70%
of annual new capacity additions [3]. The variability
and intermittency solar and wind generation
present major challenges electricity system

power flows the electricity network.
§ DC-powered devices such LED lights, and
large DC-based energy loads including electric
vehicles (EVs), industrial electrolysers, data
centres, and semiconductor manufacturing
plant will become more prevalent.

Ultimately, consumer electrical energy, P2X
energy demand still fits under the umbrella an
“all-electric” society.
In other words, the lack sufficient transmission or
distribution infrastructure now limiting the uptake
of zero carbon generation plants [4]. Electricity derived from carbon neutral
sources can converted into more useable form
of chemical energy. For loads like long-distance
aviation the manufacture energy-intensive
materials, some other source carbon-neutral
sustainable energy might needed.1 Integration intermittent
renewable energy
Renewable energy sources such solar and wind
are rapidly increasing their share global electricity
generation. These fuels can then be
converted back electricity when generation from
the renewable source insufficient. This has led grid congestion
in transmission and constraints wind and solar
generation output many parts the world.

cases, indirect use carbon neutral sources might
be available.1. During
a generation shortage, P2X plants can turned
off; during generation excess, energy can be
converted hydrogen other synthetic fuels as
a form energy storage.

require major upgrades existing electricity assets,
the construction new dedicated transmission
lines, and/or large-scale energy storage (in the
case congested grids) save generated energy
for later time when sufficient network capacity is
available.
Many key features all-electric society will rely
on power technologies:
§ Generation technologies such solar are
fundamentally based technology. One example
of P2X technology that expected proliferate
in future energy systems hydrogen generation
by electrolysis, splitting water into hydrogen and
oxygen molecules with direct current (DC).
§ Battery and many other energy storage
technologies use electricity.2 Changing power system
characteristics
The shift all-electric society brings significant
changes and challenges the operation of
electrical power systems, introduced below. This critical
challenge that will need swiftly met reach
the goal all-electric society. P2X technologies can also
assist the operation the carbon neutral electrical
grid, helping balance demand and supply.17

While many energy loads (or end-use technologies)
can supplied directly electrical energy, is
likely that for some, electricity will not feasible
source energy. This now being referred to
as the Power-to-X (P2X) concept, where energy
produced from renewable sources converted into
power fuels and clean chemicals such green
hydrogen, ammonia, synthetic hydrocarbons like
methane, methanol and synthetic natural gas, or
into other useful forms energy, such heat
