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 7.3. 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]. 3. Initially designed for MW charging, MCS will eventually support to 3. 3.3.3. In Europe, 15% penetration trucks 2030 is projected require connections MW to supply MCS chargers locations with the highest power-demand [32]. Several chargers could deployed together highway service station. Nearly all major truck 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. The commercial markets for these applications are further explored Sections 3. .3. MCS locations will located primarily along central highways.1 Megawatt-scale loads 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 is one the key pillars hydrogen economy. Figure 3-2 presents further estimates of MW-scale truck charging deployment various countries across Europe. 3.1. MVDC could also used directly couple electrolyser to nearby renewable energy generators.3. Globally, megawatt-scale charging infrastructure expected expand rapidly the 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 nearly [34]. Electrolysers are likely operate both and scale. The average size electrolysis plant also expected increase from tens of MW today hundreds over the next decade [34].1 charging One key example megawatt-scale end-use application charging. To address these issues, the Megawatt Charging System (MCS) currently under development and standardization. In parallel, major data centre operators are committing source zero-carbon electricity on 24/7 basis within the same grid.28 The MVDC grid interconnection networks, and major new loads such EVs and batteries, and reinforcement high density urban distribution networks. MVDC can also improve power density the installation, allowing for higher power capacity within given space and reducing cable size on-site.1
