How can hydrogen help decarbonize economies?

The U.S. Department of Energy announced $7 billion to fund the country’s first clean hydrogen hubs

Here’s what you need to know about hydrogen:

The U.S. Department of Energy (DOE) recently announced the historic investment of $7 billion to fund the country’s first clean hydrogen hubs. Two of the seven proposed regional hubs will be in California and Texas, where Sempra companies have vast energy networks and are well-positioned to help develop the clean hydrogen economy.

More than $1 billion is expected to be allocated to the Alliance for Renewable Clean Hydrogen Energy Systems (ARCHES), the California hydrogen hub where Sempra California’s SoCalGas is a proud collaborator ready to leverage its innovation in hydrogen. Additionally, more than $1 billion is expected to be allocated to HyVelocity, the Gulf Coast hydrogen hub where Sempra Infrastructure is one of seven core industry partners.

What is hydrogen and why is it important?

Hydrogen is the most abundant element in the universe and is well-positioned to play a major role in the low-carbon energy mix due to its versatile and sustainable qualities. Hydrogen can be produced and consumed with zero emissions when produced from renewable energy sources. It can also be produced from natural gas to create a low-emissions gas that can complement renewable energy to help further advance the global energy transition underway.

From providing a potential solution to the renewable energy storage dilemma, to supporting the transition to low- and zero-emission vehicles, hydrogen technology holds great promise for our cleaner energy future.

Sempra California’s utilities SoCalGas and SDG&E are participating in more than 20 hydrogen research and demonstration projects that aim to enhance grid resiliency and help decarbonize the economy.

Developing necessary infrastructure

Once renewable energy is converted into hydrogen, it needs to be stored and transported safely. Due to the large amount of renewable generation in California, utilizing the extensive natural gas pipeline network is an attractive and potentially scalable option for storing and transporting hydrogen.

Hydrogen hubs like those designated and funded by the DOE are envisioned to accelerate the use of hydrogen when all stakeholders come together in regional hubs. Each hub is expected to be supported by businesses that will produce, process, deliver and store hydrogen before it goes to consumers, such as hard-to-abate industries, including the transportation sector. However, modern infrastructure is the key enabler of the hydrogen economy.

Sempra companies have significant expertise in building, managing and operating pipeline infrastructure — infrastructure that is necessary to advance the hydrogen economy. In addition to upstream production facilities, the hydrogen industry needs pipelines, storage and potentially import and export terminals to satisfy the global hydrogen market that may emerge as countries around the world look to decarbonize.

Achieving cleaner transportation

The energy transition will need to address the transportation sector, which is the largest contributor to greenhouse gases in California. That’s why we are actively exploring how hydrogen and fuel cell electric vehicles could provide a much greener option compared to ones powered by gasoline.

Fuel cells are two to three times more efficient than gasoline, according to the U.S. Energy Information Administration. With a much longer range and shorter fueling time compared with battery electric vehicles, fuel cell electric vehicles have the potential to become an important component of the energy transition and the hydrogen economy.

SoCalGas is underway advancing fuel cell technology and was previously awarded $7 million in funding from the DOE to advance lower emissions vehicle technologies such as fuel cell technology that will power trucks and transit buses.

Advancing the energy transition

We believe the future of energy is clean electrons and cleaner molecules working in tandem — and hydrogen fits squarely in the mix. Across the Sempra family of companies, we are committed to furthering the energy transition across North America through innovation in hydrogen technology and more.
