(j) all required fence extensions and replacements;
(k) any required modifications to the grounding and bonding Systems at each site to conform to the Specifications;
(l) any required modifications to the pressurizing equipment to conform to the Specifications, including the pressurizing equipment manifolds and dehydrators; and
(m) any other miscellaneous site work necessary to prepare Incumbent's sites for the installation and operation of the new System.
Modifications Required. Although the blending of hydrogen is technically feasible, the combustor component of a turbine requires major redesign to utilize 100% hydrogen as the fuel. 100% hydrogen turbines are still under development with a TRL 4 to 7 and possible application in 3 to 10 years (Hers, ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇ ▇▇▇▇, van de Water, & Leguijt, 2018). No commercial 100% hydrogen turbines are currently in operation. The modifications currently required are therefore based on short-term goals of partially mixing hydrogen in fuel-flexible turbines. The H-Vision project reviewed the costs associated with modifying current power plants in the Rotterdam area for use with hydrogen. For solid fuel (e.g. coal) fired power plants the modification costs fall under three main items (H-Vision, 2019): • Investment in and installation of new gas turbines; • Modifications to enable hydrogen firing in the preheat sections; and • Cost of full steam integration between the hydrogen production plant and the power plants, plus steam transfer and condensate return lines. The cost of full steam integration is specific to the concept developed for the H-Vision feasibility study, which entails a high degree of steam/utilities integration between the existing coal-fired power plants at Maasvlakte and the new blue H2 production plant.
Modifications Required. To enable the existing refineries in the Port of Rotterdam to use hydrogen to produce high- temperature heat instead of firing RFG, several modifications would be required. Fuel-flexible burners would be required in the refineries but also a new transport network would be required to allow for the RFG to be utilized for hydrogen production. New safety modifications would also be required alongside upgraded de-NOx units. As illustrated in Figure 4, one cost efficient option to utilize the RFG from all five refineries for hydrogen production is through one centralized hydrogen plant. This would require infrastructure modifications to allow for suitable transfer pipelines and grids. The hydrogen plant would also be required to meet the following requirements: • “Fired heater burners would have to be replaced by fuel-flexible burners which can fire fuel with a very high hydrogen content. o Instrumentation, safeguarding and controls around the furnaces also have to be upgraded to enable seamlessly switching between fuels while in operation. o In addition to replacing burners, new fuel distribution systems would have to be installed to supply hydrogen fuel. • Firing a hydrogen-rich fuel increases burner flame temperatures, resulting in higher NOx emissions. o This is generally not regarded as a show-stopper and ultra-low-NOx burner technology is under development. A high margin was applied to cost estimates for furnace modifications to account for this. • As a consequence of various process upsets, the H2S concentration in RFG frequently spikes up to levels of 10,000 ppm and above. The current frequency is several times per year, so it’s important to address this. o The design of the pre-treatment section of the H-vision hydrogen production plant should take the concentration spikes into account.
