ARCHES is a public-private partnership to create a sustainable statewide clean hydrogen (H2) hub in California, utilizing local renewable resources to produce hydrogen with the objective to decarbonize fully the regional economy, while prioritizing environmental justice, equity, economic leadership and workforce development.

Clean H2[1] from renewable sources offers enormous potential for a zero-carbon energy future. The Biden Administration’s Hydrogen Earth Shot Challenge aims to reduce the cost of H2 by 80% within one decade, from the current ~$5 per kilogram (kg) down to $1 per kg. In support of this goal, the Infrastructure Investment and Jobs Act (IIJA)[2] aims to establish a network of regional hubs that will deploy clean H2 technologies at scale. 

ARCHES Principles


Leveraging California’s size and diverse geography and economy to produce, transport, store, and use H2 at scale with multiple clusters of each, provides an ideal H2 test-bed for the nation.


California has long led the nation and the world in environmental innovation and policy and will do so again with clean H2.

Stakeholder and Community-Engaged

Built-in and ensured at all stages of the process.

Equity and Justice Centered

Prioritized in all decisions with a focus on California’s impacted, disadvantaged, low-income, and tribal communities.

Aligned with State Interests

To move California toward a robust H2 economy and marketplace, and a cleaner, greener future.


Focused on implementation with targeted research and innovation to achieve the DOE’s $2/kg 5-year goal and the administration’s $1/kg 10-year goal.

Objective and Unbiased

Representing and ensuring the interests of all parties.


Considering all aspects of a successful H2 economy.

Background: Federal Hydrogen Hub Program

The IIJA appropriates $8B over 5 or more years to establish at least 4 regional H2 hubs, with a minimum of one focused on renewable sources. Hubs will create a network of clean H2 producers, consumers, and infrastructure to deliver clean H2 at a cost of $2/kg by 2026 and $1/kg by 2031. The federal program will consist of a 3-18 month planning phase and 8-12 year deployment phase, as specified by The US Department of Energy (DOE) Notification of Intent.[3] The DOE will require a 1:1 cost share from award recipients for hub construction and deployment. The majority of hub funding will support technology demonstrations and deployments, such as electrolyzers to produce clean H2 at solar power plants, infrastructure to transport H2, and end users like heavy-duty trucks to consume the H2. 7-10% of hub funding is expected to go toward research, complemented by synergistic DOE research grant funding. The hubs must demonstrate and evaluate methods for H2 production, processing, delivery, storage, and end-uses, and that they can become part of a national H2 network to facilitate an H2 economy.[1] Additional DOE support after the hub funding is expected to connect regional hubs and continue building a national H2 economy. Environmental and energy justice, workforce development, safety, and codes and standards are all additionally integral to the DOE clean H2 hub program. The DOE’s Funding Opportunity Announcement (FOA) is anticipated in September-October 2022, setting criteria and a deadline for hub applications.

ARCHES: A Statewide Partnership for a California Hub

ARCHES is a statewide public-private partnership built on California’s long-standing H2 and renewable energy leadership to serve as the applicant and organizer for a statewide H2 hub.

The State—led by  GO-Biz alongside other state agencies, the legislature, local governments, and the State’s institutions of higher education, including UC and its three national laboratories—provides vision, leadership, oversight, accountability, and matching funds. Industry partners bring deep technical expertise and capability for building an H2 network in California and significant in-kind matching capacity. Local governments, environmental justice advocates, nonprofits, and organized labor bring a strong focus on community engagement, public health, environmental protection, workforce development, and other issues of critical importance to ARCHES.

ARCHES will include major deployment clusters in the Los Angeles Basin and Bay Area and extend into the Central Valley, Inland Empire, and other regions (and possibly neighboring states) with high renewable resources, geologic storage possibilities, key transportation corridors, and need for clean energy and reduced pollution.

Why a California renewable H2 hub is poised to succeed and meet California’s needs

The IIJA requires at least one Hub to produce H2 using renewable resources. California’s leadership and early efforts on transitioning to 100% renewable, zero-carbon electricity, and developing H2 infrastructure makes the State especially competitive to win a renewable clean H2 hub award. California’s extensive renewables portfolio will be essential to power electrolyzers that make clean, renewable H2, decarbonize sectors that are hard to electrify directly, and develop long-duration energy storage solutions.

An H2 hub is an excellent investment of California resources. It will fast-track the development and implementation of H2 infrastructure in California, grow California’s clean energy economy, advance environmental justice goals by accelerating the transition to zero-emissions technologies in polluted communities, provide good high-road union careers and clean energy job training to California’s workforce, provide R&D funding to develop the technological innovations needed to advance clean H2 technology, and kickstart California’s H2 marketplace, giving California a competitive edge as the new H2 economy emerges.

The H2 economy also presents real opportunities to retain and expand California’s clean energy workforce, which will build out the vast renewable energy generation needed to power electrolyzers and implement H2 production, storage, delivery, and end-use technologies. The conversion of significant fossil fuel distribution infrastructure will also allow for sustained employment otherwise at risk in the transition to clean energy.


[1] “Clean hydrogen” is defined in the IIJA as H2 produced with a carbon intensity equal to or less than 2 kilograms of carbon dioxide-equivalent produced at the site of production per kilogram of H2 produced. Federal agencies and stakeholders may re-evaluate this definition over the next 5 years (Sec. 40315 (a)),
