Producing hydrogen from the electrolysis water
is one the key pillars hydrogen economy.
A related market MVDC application involves
integrating local renewable energy generation with
high-power charging.3.3.
The commercial markets for these applications are

The number electrolyser projects around the
world has been growing.
In parallel, major data centre operators are
committing source zero-carbon electricity
on 24/7 basis within the same grid. MVDC
could also used directly couple electrolyser
to nearby renewable energy generators. Electrolysers are
likely operate both and scale. MVDC
technologies are well suited for directly connecting
generation data centre loads. Long-range transportation
poses major challenges for charging systems,
energy supply, and supporting infrastructure.3.28

Data centres are major energy consumers, with
most operating MW-scale.3.
To address these issues, the Megawatt Charging
System (MCS) currently under development
and standardization. Several chargers
could deployed together highway service

manufacturers plan launch battery-electric trucks
in the coming years.1 3.1.
Globally, megawatt-scale charging
infrastructure expected expand rapidly the
coming decade.1.
In Europe, 15% penetration trucks 2030
is projected require connections MW
to supply MCS chargers locations with the
highest power-demand [32].5 [33].

Electrolysis highly energy-intensive process,
requiring high-power input. 600 projects, with a
combined capacity 160 GW, were announced
in 2023 alone, with annual demand increasing by
nearly [34].3.
MCS locations will located primarily along
central highways. The average size electrolysis
plant also expected increase from tens of
MW today hundreds over the next
decade [34]. Initially designed for MW
charging, MCS will eventually support to

to install 800 highway charging locations

7.1 Megawatt-scale loads
As power systems transition toward all-electric
society, the number megawatt-scale loads is
expected grow significantly. Wind turbines and utility-
scale systems, often located near highways due
to space constraints, could connect via MVDC to
directly power MCS charger locations reducing
conversion losses and increasing overall efficiency. Incorporating MVDC
technology will enhance energy efficiency by
reducing conversion losses, eliminates the
need for multiple AC-DC conversion stages
