Introduction: Why the Pacific Northwest Is America’s Renewable Hydrogen Frontier
The Pacific Northwest sits at a remarkable intersection. It possesses some of the cheapest, cleanest electricity in the United States — driven by the Columbia River’s hydropower system, anchored by Grand Coulee and Bonneville Dams — alongside fast-growing wind and solar capacity, readily available water sources, and a regional policy environment deeply committed to decarbonization. These are precisely the inputs that make world-class green hydrogen production not just possible, but economically compelling.
At the heart of every renewable hydrogen project — whether it’s fueling heavy-duty trucks, making green fertilizer near Richland, Washington, or providing clean energy storage across the tri-state region — is a single device: the electrolyzer. It is the electrolyzer that converts electricity and water into hydrogen, and it is the performance, cost, and reliability of the electrolyzer that will ultimately determine whether the Pacific Northwest realizes its full hydrogen potential. Specific considerations where Nel has found use cases for in the Pacific Northwest range from purity (in various semiconductor applications) to price, (remote locations without access to low-cost hydrogen).
Nel Hydrogen has been manufacturing electrolyzers since 1927. Today, with more than 3,800 systems delivered across 80+ countries, we are a proud partner of the Renewable Hydrogen Alliance (RHA) — the Pacific Northwest’s longest-running, locally-led hydrogen advocacy and industry organization. With a leading role in electrolyzer research, development, and demonstration Nel is pleased to partner with RHA to release “Electrolyzer Evolution” – a review of the innovations and scaling efficiencies that will define the cost and performance of the next generation of electrolyzers.
This post provides background for “Electrolyzer Evolution”, and outlines the importance of electrolyzers for the region’s energy, economic, and environmental ambitions. Dig into the report to learn more about electrolyzer performance improvements, R&D programs, and why the technology horizon has never looked better for PNW stakeholders.

The Pacific Northwest’s Unique Electrolyzer Advantage
Electrolyzers are only as green — and only as economical — as the electricity powering them. This is where the Pacific Northwest holds a structural edge over virtually every other region in the United States.
Hydropower: The Perfect Electrolyzer Partner
As Congressman Dan Newhouse has noted, the Columbia River Basin generates some of the cheapest and most reliable clean electricity in the country. Seasonal surplus and curtailed hydro (as well as other renewable) — power that might otherwise go unused — can be directed into electrolyzers to produce storable, dispatchable clean hydrogen at minimal marginal cost. This is an energy abundance story unique to our region.
Electrolyzers benefit enormously from stable, low-cost baseload power. Alkaline electrolyzers, in particular, run most efficiently at steady-state conditions — a profile that aligns well with the Pacific Northwest’s large hydropower fleet. PEM electrolyzers, on the other hand, can ramp rapidly up and down, making them ideal partners for variable wind and solar generation as the region expands those resources.
A Region Built for Electrolysis at Scale
The tri-state area spanning Washington, Oregon, and Montana, has strong local industrial and manufacturing demand for high purity hydrogen. Every kilogram of hydrogen for projects ranging from Sustainable Aviation Fuel (SAF), to fertilizer, to fueling will come from the merging capillaries of the PNW hydrogen corridors.
Figure 1: Pacific Northwest Renewable Energy Assets and Their Relevance to Green Hydrogen Electrolysis
| PNW Energy Asset | Capacity / Scale | H₂ Relevance | Key Projects |
|---|---|---|---|
| Columbia River Hydropower | Grand Coulee & Bonneville Dams — among cheapest clean power in U.S. | Lowest-cost electrolysis input in the nation | PNWH2 Hub nodes (WA, OR, MT) |
| Wind (Eastern WA / OR) | Rapidly expanding capacity | 24/7 renewable pairing with hydro | AltaGas Ferndale (~265 MW load) |
| Solar (Columbia Basin) | Growing utility-scale installations | Daytime electrolysis peak production | Atlas Agro Richland (~300 MW load) |
| Excess / Curtailed Hydro | Seasonal surplus availability | Electrolyzer load-balancing opportunity | PNWH2 Hub energy strategy |
The PNWH2 Hub, the 45V Tax Credit, and the Policy Foundation
Technology can only do so much. For the Pacific Northwest’s hydrogen potential to be fully realized, the policy and funding framework must hold. On this front, there are both real reasons for optimism and legitimate challenges that the RHA community needs to navigate.
The PNWH2 Hub: Progress and Resilience
The Pacific Northwest Hydrogen Hub, led by the Pacific Northwest Hydrogen Association (PNWH2), was selected in 2023 to receive approximately $1 billion in DOE funding — disbursed in phases as project milestones are met. The Hub’s Phase 1 funding of $27.5 million has been deployed, and the consortium has been actively working on project siting, community engagement with tribal nations, and labor partnerships across Washington, Oregon, and Montana.
The Hub has faced headwinds: Portland General Electric and Mitsubishi Power withdrew from the Boardman, Oregon node in mid-2025, and the broader federal clean energy funding environment under the current administration has introduced uncertainty. But the two remaining anchor projects — Atlas Agro’s $1.5 billion green fertilizer facility near Richland, WA, and AltaGas’s hydrogen production project at the former Alcoa smelter site in Ferndale, WA — are pressing ahead. The PNWH2 team has been clear: project adjustments were always anticipated in the early phase of a nascent industry.
The 45V Tax Credit: Non-Negotiable for Project Economics
For any renewable hydrogen project in the Pacific Northwest to pencil out financially, the Section 45V Clean Hydrogen Production Tax Credit is essential. PNWH2 joined over 100 organizations in a letter to Congressional leaders urging support for 45V, calling it critical for the industry and for American competitiveness in energy technology. Nel fully supports this position: the 45V credit reduces the effective cost of renewable hydrogen production, narrows the gap with fossil hydrogen, and enables the long-term offtake agreements that make large electrolyzer projects bankable.
The good news: as Senator Maria Cantwell has pointed out, the Northwest’s renewable hydropower makes the region a natural fit for meeting 45V’s clean energy requirements — particularly important given the credit’s incrementality and temporal matching rules, which the region’s existing renewable infrastructure is well-positioned to satisfy.
What the RHA Community Can Do
The Renewable Hydrogen Alliance plays a vital role in sustaining policy momentum. For RHA members, the most impactful near-term actions include:
- Advocating for 45V tax credit preservation and clarity at the federal level
- Supporting PNWH2 Hub Phase 2 funding authorization and DOE EIS process integrity
- Engaging with state-level clean energy programs in Washington and Oregon that provide match funding and off-take support
- Participating in RHA working groups on hydrogen fueling infrastructure for medium- and heavy-duty transportation
Conclusion: The Electrolyzer as the Pacific Northwest’s Clean Energy Engine
The Pacific Northwest has everything it needs to become the leading renewable hydrogen region in the United States: world-class renewable resources, strong state policy frameworks, a network of committed industry and tribal partners, federal hub funding, and a rapidly maturing electrolyzer technology base.
Nel’s role in that story is to keep pushing the electrolyzer performance frontier — delivering systems that are more efficient, more durable, lower-cost, and better matched to the region’s unique renewable energy profile. From the PEM production line in Wallingford to the next-generation pressurized alkaline platform launching in 2026 and game-changing PEM innovation to follow, our R&D investments are timed precisely for the Pacific Northwest’s build-out moment.
The Renewable Hydrogen Alliance has been the connective tissue of this regional ecosystem since before hydrogen was fashionable. We are proud to be part of that community — and committed to contributing the technology breakthroughs that will make the Pacific Northwest a model for renewable hydrogen development worldwide.
