Alternate Marine Power (AMP), which can also be referred to as shore power or cold ironing, is the technology that enables vessels that are moored at a port to turn off their onboard diesel engines and get their power supply directly from the shore-based power grid. By doing so, the system drastically decreases the consumption of fuel and the release of carbon dioxide, nitrogen oxides, sulfur oxides, and particulate matter to the atmosphere during the stay of the ships.

The essential advantages of AMP are the elimination of harmful emissions in port areas, the reduction of noise levels, the saving of money through lower operating costs of the vessels, and the facilitation of the adherence to strict environmental regulations, which are among the factors that lead to less polluting and more sustainable maritime operations.

The expansion of the alternate marine power market is mainly influenced by worldwide efforts to minimize emissions at the portside, more stringent regulations at the international level imposed by organizations such as the IMO (International Maritime Organization), and the increased implementation of green port initiatives.

In fact, the increase in the price of fuel, the technological progress of shore power, and the government subsidies for the clean maritime infrastructure are some of the factors that are speeding up the adoption of AMP. Moreover, the growth of the cruise and container shipping industries, along with the increased concern for environmental sustainability, are among the factors that are facilitating the rapid installation of AMP systems in the major ports ‍worldwide.

Key Drivers:

Increasing Urbanizations

One of the main drivers of the growth of the alternate marine power market is the rise of cities surrounding coastal and port areas. The reason behind this is that these areas require the mitigation of air and noise pollution that ships at docks produce. As a result, local authorities and port management have to implement cleaner technologies to maintain good air quality and public health since more people live and work close to the docks. AMP is a technology that enables ships to use shore power and, therefore, they can turn off their onboard diesel generators.

This is a great reduction of pollutant emissions and noise. Such measures allow ports to become cleaner and in line with urban environmental standards, which, in turn, facilitates the ‍market to grow ‍further.

• For instance, according to the data published by World Bank Group, currently, 4.4 billion people, or more than half of the world's population, reside in urban areas. This trend is predicted to continue, with nearly seven out of ten people living in cities by 2050, when the urban population is predicted to more than quadruple.

Restraints:

Maintenance and Safety Challenges

Such issues as maintenance and safety concerns can be the root reasons for the limited expansion of the alternate marine power market. The systems feature high-voltage electrical connections between shore and ship, thus requiring strict safety protocols, skilled personnel, and regular inspections to avoid electrical faults, overheating, or accidents. All these factors elevate operational complexity and costs, hence a few ports and vessel operators may decide against adoption.

• Counterbalance Statements: It is a suitable measure to introduce automated monitoring systems, uniform safety procedures, and well-rounded training programs for the port staff. Additionally, the use of smart connectors and insulated cable systems that reduce the chance of human error and increase operational reliability is also a viable ‍way.

Opportunities & Trends:

Port Electrification and High Voltage (Above 11 kV) AMP System Developments

One of the main future trends of the alternate marine power market is the development of port electrification and the hybrid AMP system as ports are going global for low-carbon operations. Electrified ports powered by renewable energy, energy storage and hybrid AMP systems - mixing grid power with solar, wind or battery backups - provide more reliability and sustainability.

These systems allow a continuous power supply even in the case of grid instability while at the same time reducing emissions and operational costs further. As a result of the green port initiatives and carbon-neutral goals enforced by governments, the use of hybrid AMP technology is probably to be a new feature of smart ports of the next ‍generation.
