Incorporating MVDC
technology will enhance energy efficiency by
reducing conversion losses, eliminates the
need for multiple AC-DC conversion stages.
3. Long-range transportation
poses major challenges for charging systems,
energy supply, and supporting infrastructure.
A related market MVDC application involves
integrating local renewable energy generation with
high-power charging.3.
The number electrolyser projects around the
world has been growing. The European Union alone plans
to install 800 highway charging locations
by 2030, with combined total capacity of

Electrolysis highly energy-intensive process,
requiring high-power input.1. 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.5 [33].

In Europe, 15% penetration trucks 2030

manufacturers plan launch battery-electric trucks
in the coming years.3.3 Data centres
Data centres are major energy consumers, with
most operating MW-scale.

As power systems transition toward all-electric
society, the number megawatt-scale loads is
expected grow significantly.1 3. MVDC
technologies are well suited for directly connecting
generation data centre loads.
Many data centres are now being co-located
with large-scale renewable energy generators.75 maximum voltage 250 [31].2 Electrolysers
Producing hydrogen from the electrolysis water

Globally, megawatt-scale charging

coming decade. This represents major new network load
that MVDC networks might help accommodate. 600 projects, with a
combined capacity 160 GW, were announced
in 2023 alone, with annual demand increasing by

To address these issues, the Megawatt Charging
