E-HUB for ports
Legislation and ongoing regulation are pushing ports around Europe to decarbonize their operations. This accelerating electrification of the marine and port sector increases the demand for shore power and DC charging. At the same time, the electrification of cargo handling equipment, cars, trucks and other port equipment increases the need for high power charging solutions as well as an investment in stronger grid connections with higher capacities. To address these challenges PSW Power & Automation has developed an energy hub for ports.
At the heart of the E-HUB is our conventional shore power system. The shore power system can deliver power to any connected vessel independent of voltage and frequency. Additionally, it can charge batteries onboard the vessel with a DC fast charging connection according to applicable standards. Where required the E-HUB can cater to the charging needs of mobile battery containers, passenger speed boats, cranes, trucks, and other port equipment using a Combined Charging System (CCS) or Megawatt Charging System (MCS). In this way, the requirement for multiple systems, providing similar services, is taken out of the commercial equation.
Secondly, the increasing power demand also requires the availability of sufficient capacity from the electricity grid. By its nature, shore power and DC fast charging are generating high power peaks for shorter time periods. These load variations trigger the need for costly upgrades of the electrical infrastructure to ensure resilience against peak loads. With the electrification trend and an energy crisis on the horizon, grid availability becomes a challenge. The E-HUB addresses this with the possibility to integrate alternative energy sources such as solar and hydrogen. In addition, the E-HUB has an integrated battery system for energy storage.
Power, energy and investment optimalisation are key elements in the E-HUB solution. In addition to providing flexible power to various consumers it can operate as a power source feeding back to the port electrical network or grid. This increases utilization of the system when there are limited consumers connected. Peak shaving, grid stabilization, energy optimisation and emergency power are functions of the E-HUB mitigating challenges caused by large load variations as a result of the never-ending electrification trend to ensure emission reduction.
Mobile E-HUB for construction sites
The electrification of the construction industry requires increased grid availability as new machinery is being electrified. The energy consumption in a typical construction site is significantly higher than after the construction project has been completed. Getting higher capacity power supplies to building sites is driving both costs as well as waiting times for permits and connections to be completed. To reduce these effects, it can therefore be profitable setting up a Mobile E-HUB.
At the the heart of the E-HUB is our Mobile battery system that covers peak loads while the limited grid connection charges the batteries based on the average assumed load. In addition to delivering power to any connected consumers the E-HUB can charge electric trucks, excavators and other equipment using a Combined Charging System (CCS) or Megawatt Charging System (MCS).
In some cases, there is limited of or no power available to the construction site. In this case the E-HUB offers the possibility to integrate alternative energy sources such as solar and hydrogen. In addition, the E-HUB can charge mobile battery containers that can be transported to the electric consumer and avoid moving the construction equipment back to the E-HUB for recharging.
Additional functions such as peak shaving, grid stabilization, energy optimalisation and emergency power are functions of the E-HUB mitigating challenges caused by large load variations as a result of the never-ending electrification trend to ensure emission reduction.
