The commercial markets for these applications are further explored Sections 3. This represents major new network load that MVDC networks might help accommodate. A related market MVDC application involves integrating local renewable energy generation with high-power charging. In Europe, 15% penetration trucks 2030 is projected require connections MW to supply MCS chargers locations with the highest power-demand [32].1. MVDC can also improve power density the installation, allowing for higher power capacity within given space and reducing cable size on-site. . Many data centres are now being co-located with large-scale renewable energy generators.28 The MVDC grid interconnection networks, and major new loads such EVs and batteries, and reinforcement high density urban distribution networks.1 Megawatt-scale loads As power systems transition toward all-electric society, the number megawatt-scale loads is expected grow significantly.3.3.3. 600 projects, with a combined capacity 160 GW, were announced in 2023 alone, with annual demand increasing by nearly [34].1. Nearly all major truck manufacturers plan launch battery-electric trucks in the coming years. MCS locations will located primarily along central highways. MVDC technologies are well suited for directly connecting generation data centre loads.2 Electrolysers Producing hydrogen from the electrolysis water is one the key pillars hydrogen economy. 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. In parallel, major data centre operators are committing source zero-carbon electricity on 24/7 basis within the same grid.3 Data centres Data centres are major energy consumers, with most operating MW-scale.1 charging One key example megawatt-scale end-use application charging. 3.3. Electrolysis highly energy-intensive process, requiring high-power input.1 3. MVDC could also used directly couple electrolyser to nearby renewable energy generators. Initially designed for MW charging, MCS will eventually support to 3. The average size electrolysis plant also expected increase from tens of MW today hundreds over the next decade [34].5 [33]. Several chargers could deployed together highway service station.1. Globally, megawatt-scale charging infrastructure expected expand rapidly the coming decade. The European Union alone plans to install 800 highway charging locations by 2030, with combined total capacity of 7. Incorporating MVDC technology will enhance energy efficiency by reducing conversion losses, eliminates the need for multiple AC-DC conversion stages. The number electrolyser projects around the world has been growing. Figure 3-2 presents further estimates of MW-scale truck charging deployment various countries across Europe. 3. Long-range transportation poses major challenges for charging systems, energy supply, and supporting infrastructure. 3.3.3. 3.75 maximum voltage 250 [31].3. To address these issues, the Megawatt Charging System (MCS) currently under development and standardization. Electrolysers are likely operate both and scale
