1.0 SUMMARY OF WORK REQUIREMENTS

This Project Manual includes requirements for a stand-alone hydrogen-fueling station that will use delivered liquid hydrogen (“LH2”) as the primary storage medium. The station will support the needs for the City of Pasadena Department of Transportation and its planned fleet of fuel cell (FC) buses.

The new station will be capable of peak fueling as shown in Table 1.Error! Reference source not found. The station configuration will include one 18,000-gallon LH2 tank, two LH2 product pumps, LH2 vaporizers, GH2 storage vessels, Priority-valve panel, chillers, two gaseous hydrogen (GH2) dispensers rated for H35 (350 bar) fills, and a fixed LH2-offload pump.

Other project requirements include the following site improvements to be provided by the Design-

Builder:

• Paving and grading.

• LID-compliant landscaping per city code.

• Masonry fencing, ‘Impasse II’ or equal fencing and industrial-type automated property gates where shown, to include Kox Box, and electronic-access control at property and internal doors and gates.

• A fuel-island canopy.

• A backup generator and transfer switch with integrated diesel-fuel tank.

• A utility building containing two restrooms, an electrical room, janitorial closet, and alcove for housing the backup generator.

• A bus-parking canopy with masonry wall.

• Industrial-grade site-surveillance cameras.

The Design-Builder shall also plan, conduct and implement all safety planning required, including hydrogen-safety plan and related safety studies and requirements indicated herein.

The LH2 station shall be constructed on a design-build basis, which calls for the Design-Builder to prepare a set of engineered and approved construction drawings for all required disciplines, including mechanical, electrical connection to onsite transformer + power distribution, structural and architectural, as well as appropriate cover sheet with project data. The Design-Builder’s design and construction shall be approved by the Owner, Pasadena Building and Safey Division, and

Pasadena Fire Department, and shall also comply with the project manual, except where deviations are approved by the Owner. The LH2 station must be commercially operational by June August

2028 and 100% complete and fully accepted by the Owner by November 2028.

Work under this Project Manual requires provision of all engineered construction drawings, site construction, furnishing, delivering and starting equipment as required to make the systems functional, and a minimum 12-month warranty covering all parts, labor, workmanship, and travel, following acceptance of the project as being complete by the Owner, except for consumable materials and parts which will be covered under the Operations and Maintenance agreement. Any manufacturers’ warrantees for materials and equipment that extend beyond 12 months shall be documented and passed to the Owner. Consumable materials and parts are those items that are expected to be replaced or replenished as part of normal operation of the procured system, per the replacement schedules published by the respective equipment or system manufacturers.

As the project site is unimproved, the hydrogen fueling station will require the establishment of all

- 2 - 1/28/2026 utility infrastructure unless stated otherwise, including electrical, potable water, sanitary sewer, communications and storm sewer. A pad-mounted electrical transformer sized to support a minimum 1000A 480V secondary will be provided and set by the City of Pasadena Water and Power

Department at the north end of the site. The Design-Builder will be responsible for coordinating and making all necessary improvements and modifications to all site utilities needed for operation of the facility. Design-Builders will be required to determine the extent of upgrades and define this work in their proposal and include the associated costs in their cost proposal per utility type.

1.1 ADDITIVE ALTERNATES

Pricing for each additive alternate shall be provided net and incrementally to the base work including credit for any items from the base scope that are replaced under the alternate and shall be complete and turnkey for each listed item. Items shall be procured at the Owner’s discretion, including the possibility of procuring none of the additive alternates.

A. LH2 Offload Pump.

One LH2 product pump matching the two base units, to include a matched variable-frequency drive

(VFD) and associated inlet and outlet lines and valves needed to back up both base pumps.

B. Third LH2 Product Pump.

A boiloff-gas (BOG) recovery system, to include control valve at LH2-tank top, integrated compressor skid, GH2-warming coil, matched VFD, and two added GH2 storage vessels. Provide preliminary engineering data describing assumed or projected efficiency of GH2 capture of the proposed BOG system with proposal.

C. BOG Recovery System.

A ground-mounted LH2 delivery or offload pump, including process connections, variable frequency drive (VFD), and controls integration. Pump shall be capable of overcoming receiving-tank pressures of up to 100 PSIG and be configured to provide both top- and bottom-fill delivery to the tank.

D. Liquid-Hydrogen Commodity for (3) One-Year Terms.

Liquid hydrogen commodity for (3) one-year terms. Amounts to be delivered to the site are outlined as follows. Deliveries of LH2 to be made at 4,000 kg at a time or as otherwise agreed with the Owner. Daily fuel consumption per bus is based on an average of 168 miles / 6 miles per kg of hydrogen.

Table 1 – Calculations for Estimated Annual Fuel Consumption

Average Daily Mileage per FC Bus 168

/ Average kg of Hydrogen per Mile 6

= Avg kg Hydrogen per Bus per Day 28 x Active FC Buses 17 x Days per Year 365

= kg Net Annual Hydrogen Consumption 173,740

+ All losses (assumes BOG-recovery system) 15%

= kg Gross Annual Hydrogen Consumption 199,801

8/2027 – 7/2028: 17 active buses = 199,801 kg per year

8/2028 – 7/2029: 17 active buses = 199,801 kg per year

8/2029 – 7/2030: 17 active buses = 199,801 kg per year

- 3 - 1/28/2026

Provide pricing per kg of hydrogen for each of the three years, based on the annual quantities indicated above. Pricing shall allow for 10% consumption overage or a 35% consumption deficit each procurement year. The full buildout of the FC bus fleet is planned to be 45 buses by 2037.
