Request for Proposal (RFP)
The Port of London Authority (PLA) are the custodians of the tidal Thames with responsibility for 95 miles of the tidal Thames. We work to keep commercial and leisure users safe, protect and enhance the environment and promote the use of the river for trade and travel. The Port of London oversees 230,000 vessel movements handling over 53m tonnes of cargo each year. Unlike most UK port authorities, the PLA does no cargo handling – that is done by the individual terminals along the river that make up the Port of London.
Headquartered in Gravesend, with multiple offices in Gravesend and London, it was formed by an Act of Parliament in 1908 and employs around 400 people.
1. RFP Objectives
The purpose of this Request For Proposal (RFP) is to demonstrate the potential of a hydrogen or ammonia fuel cell based system as a replacement for existing shore based diesel generators that operate in a marine environment. The demand for electricity and the interest in alternative low carbon fuels on the tidal Thames is increasing as the maritime sector starts to decarbonise. The provision of electricity, particularly from renewable sources, can be challenging along the Thames, with the prospect of grid capacity also being reduced by decarbonisation of other sectors as well as the constraints on space for storage of power or fuel for energy provision.
The fuel cell system will be trialled at the PLA’s marine operations facility in Gravesend, providing power to warm start large tugs and maintain battery power on the UK’s first hybrid pilot cutter vessel. The chosen site is fairly constrained, but in many ways representative of many other sites along the Thames which may in the future themselves be adapted to provide alternative low carbon fuel infrastructure. It is intended that the demonstrator will:
- Prove the suitability and reliability of a fuel cell system to provide power to river vessels while minimising Greenhouse gas and air emissions
- Provide an indication of system footprint (including fuel storage and safety distance), which help to understand better the constraints and identify opportunities for such system to be applied at other maritime operational sites
- Provide insights into fuel storage, fuel supply and fuel handling, which the experience and knowledge is transferable for adopting alternative low carbon fuel technology on vessels
- Improve stakeholder understanding of safety issues around alternative low carbon fuels
- Provide training opportunities for safe handling of alternative low carbon fuels

The site selected for the trial is one of the PLA’s operational sites located in Gravesend, Kent. As illustrated in Figure 1, the site comprises a fixed structure of a yard built on the shore known as the inner quay. The inner quay is connected to a T shaped jetty with a fixed roadway jetty (approximately 110 m) into the river terminating in a paved area (approximately 20 m x 40 m) at the end, known as the jetty head.
Figure 1: Illustration of the trial site
There are two floating pontoons connected to the east side of the jetty head, the pontoons and the pedestrian walkways have a total length of approximately 110 m. There are three floating pontoons connected to the west side of the jetty head, the pontoons and the pedestrian walkways have a total length of approximately 140 m. Currently, there is a 300 kVA diesel generator on the last pontoon on the eastern side (Pontoon 5) with 2 x 86 A connection points, which provided energy to warm start tug engines, and a 100 kVA diesel generator on the last pontoon on the western side (Pontoon 1), which is used to charge the battery of a hybrid pilot cutter when off station.
The load of the 300 kVA generator demand led with an irregular and unpredictable pattern, i.e. demand could be at any time of the day and during any day of the week. The average load is in the range of 30 to 70 kVA with a maximum load of 110 kVA, with some periods of running at negligible or no load.
The 100 kVA generator is used twice per week for 6 to 7 hours to charge up the two 288 V 300 Ah batteries on the hybrid pilotage cutter. Each battery has an 86.4 kWh of charging capacity, which equivalent to a mean charging rate of approximately 29 kW and a maximum charging rate of circa 60 kW assuming the battery required a full charge.
The total fuel consumption from both generators is roughly 3350 L of diesel per week.
A single hydrogen or ammonia fuel cell-based system that can provide the power of the combined requirements and demand provided by the two diesel generators at Denton Wharf (the 100 and 300 kVA generators as listed in Background Information). Whilst for the supplier to asses, the preferred location of the fuel cell generator would be the inner corner (facing the shore) of the jetty head with a footprint of 17 m x 7.5 m (shaded area on the jetty head in Figure 1, with an approximate area of 130 m2). It is expected to distribute the power from the fuel cell power system to both pontoons on the eastern and western end and ideally, to have separate power control systems on both pontoons.
Due to the limited space at the jetty head, storage of the fuel may need to be located on the inner quay. Whilst for the supplier to assess, the preferred location of the fuel storage would be the eastern outer corner (facing the river) with a trapezium shaped footprint of approximately 70 m2 (shaded area on the inner quay in Figure 1). The given footprint should include any required safety exclusion zone. Ideally, the refuelling frequency should be no more than once a week. If fuel is to be stored on the inner quay, it is expected a pipeline will need to be installed alongside the roadway jetty connecting the storage with the power system. Containment systems already in place on the eastern side of the roadway jetty.
The two diesel generators will be remained onsite as backup and will be needed to be integrated into the fuel cell-based system.
The two diesel generators will be remained onsite as backup and will be needed to be integrated into the fuel cell-based system.
The entire project is expected to last for maximum 18 months, with a maximum lead time of 6 months and a trial period of 12 months. The use of fuel(s) will need to be monitored to fully access any environmental benefits or detriments and system efficiency of the proposed system.
Methodology and Outcome
Bidders are encouraged to propose suitable technological solutions for operating in a constrained and operational maritime site.
Data, such as the power demand, typical operation profile, and site constraints, that required for the system design is listed in the “Background Information” Section. A site visit will also be arranged (COVID rules will apply).
