Who This Checklist Is For
If you buy industrial gas for manufacturing—and you're looking at an Air Products blue hydrogen Louisiana proposal—this checklist is for you. I'm a procurement manager, not a chemical engineer or a hydrogen process expert, so I won't tell you how to design a reformer or validate a heat exchanger. What I can tell you, from tracking roughly $2.8M in annual gas spend and handling vendor selection for the past seven years, is how to compare offers without getting blindsided.
There are six steps. They are ordered the way I actually use them, not the way a textbook would order them.
Step 1: Size the Demand Curve Before You Compare Suppliers
The first mistake I made was comparing unit prices before knowing my own demand curve. It's easy to think a low price per thousand cubic feet is a good deal. But if your plant's consumption is spiky, then a flat-rate contract can turn into a bill full of demand charges.
In 2023, I audited a year of consumption data and found that 60% of our gas bill came from four peak days. We had a low base rate and then huge overrun fees. The supplier's pricing looked competitive until I modeled it against our actual use.
So step one: pull a year of hourly or daily consumption data. If you can't get hourly, daily is fine. Send that data to every supplier. The best quote for a flat load is often the worst quote for a variable load. This also matters for tire manufacturing plants, where nitrogen for tire curing has sudden demand spikes when a curing line starts up.
Step 2: Build a TCO Spreadsheet, Not a Price List
This is basically where I live. I have a spreadsheet that calculates total cost of ownership for each quote. It's not fancy. Columns for:
- Product price per NCM or per scf
- Monthly facility charge
- Delivery or pipeline charge
- Energy or consumable charge for on-site generation
- Maintenance and spare parts
- Backup supply fees
- Minimum take-or-pay volume
- Escalation formula and index
- Fees for demand spikes above contracted capacity
- Early termination penalties
When you put all that in a spreadsheet, the 'cheap' price stops being cheap. I also use an automated invoice tracker that flags any line item that changed from the prior month. That is how I caught the carrier fuel surcharge on the first quote. The system isn't a replacement for reading the contract; it's a triage tool.
Step 3: Ask for a White Contract
This step is the one most people ignore. Ask your Air Products rep for a 'white contract.' That's my shorthand for a contract with no gray clauses: every fee, escalation formula, force majeure trigger, and liability cap written in plain language. In some procurement contexts, a white contract means a clean, transparent agreement, as opposed to one with hidden provisions.
I learned never to assume standard terms are consistent. When comparing three gas supply proposals, one had the same base price on the first page but buried a water treatment surcharge on page seven. The other two didn't have that line. I almost signed the first one because I assumed same product meant same contract structure. It doesn't.
If a supplier insists on 'our standard template' and won't show you every fee line, that's not necessarily a deal-breaker. But it's a red flag. In our vendor files, I tag this as 'air-products-blue-hydrogen-louisiana' so the contract version doesn't get lost.
Step 4: Pressure-Test the Carbon Claims
Air Products and Chemicals Inc. is making a major blue hydrogen push in Louisiana, and the environmental story is a big part of the pitch. Blue hydrogen is still manufactured from natural gas with carbon capture. The 'blue' part depends on how much CO2 is actually captured and stored, not on how the project is marketed.
I'm not a sustainability auditor, so I don't validate carbon intensity numbers myself. What I do is ask for three things:
- The lifecycle or site-specific greenhouse gas footprint for the proposed supply route, not just a corporate average
- Documentation for the CO2 capture and storage arrangement, because 'blue' depends on sequestration
- A clear statement of who takes the risk if the carbon capture unit underperforms, or if the sequestration injection plan changes
The FTC Green Guides say environmental claims need substantiation, and a big supplier like Air Products should be able to provide it. If they can't, that's a risk you're carrying into your own reporting, even if the gas price is nice.
Step 5: Verify Backup and No-Happy-Path Scenarios
Blue hydrogen plants are big infrastructure projects. The Louisiana complex will be a major source when it's up, but 'when' is the word to watch. If the plant is delayed, or the gas pipeline upstream has a problem, where does your contracted volume come from?
I once approved a vendor for a peak shaving project and immediately felt post-decision doubt. I hit confirm and thought: did I ask about backup capacity if their main plant goes down? I hadn't. The delivery ended up fine, but only because we added a backup supply clause after the fact.
Before signing, ask:
- Do you have redundancy for the specific supply point I'm connected to?
- What is guaranteed deliverability during a demand spike?
- Who coordinates if the plant and pipeline are operated by different business units?
- What is the notification time for curtailment?
I want to say the curtailment notice on one contract we reviewed was 72 hours, but don't quote me on that. The point is to get it in writing. For nitrogen used in tire manufacturing, especially in tire curing, even a short interruption can ruin a batch. Backup supply matters more than price.
Step 6: Compare Project Execution Risk, Not Just Gas Prices
This gets into supply risk territory that's outside my core expertise, so I'll keep it simple: a quote based on a future plant that hasn't started up should be evaluated differently than a quote from an existing asset. Ask for project status, expected startup date, and how much capacity is already committed. A low price tied to speculative capacity is not a bargain; it's an option you don't control.
In 2024, several industrial gas buyers I talk to started asking for right of first refusal on Air Products' Louisiana blue hydrogen output. That is not the same as firm supply, and it should not be priced like firm supply. The best move is to get a named account manager and a contractual path from project milestone to firm supply.
Common Errors to Avoid
Buying on press releases. If someone says the plant will be online next quarter, ask for environmental permit milestones, not just the announcement.
Ignoring contract length. A ten-year take-or-pay deal can give a better unit price, but if your demand drops, you still owe. I'm not a legal expert—consult your counsel—but the exit clause is part of the cost.
Looking only at hydrogen. Air Products also sells membranes, specialty chemicals, welding gases, and nitrogen. If they bundle products, the bundle discount may hide a premium on one line. Break out every product in your TCO spreadsheet.
Bottom line: Air Products' blue hydrogen Louisiana project is genuinely interesting for industrial gas supply. But interesting is not a reason to sign. Use the demand curve, the TCO spreadsheet, and a white contract request to separate a real offer from a low headline price. I still second-guess decisions in this category because the cost of being wrong is in six figures. That's why I use the checklist.
