For the foreseeable future, most hydrogen fuels will be produced from natural gas by an energy-intensive and polluting method called the steam conversion process, which uses steam, high heat and pressure to break down methane into hydrogen and carbon dioxide.

Blue hydrogen uses the same process but applies carbon capture and storage technology, which involves capturing carbon dioxide before it’s released into the atmosphere and then pumping it underground to lock it up. But that still doesn’t account for the natural gas that produces the hydrogen, powers the steam reforming process, and drives the CO2 capture. Cornell’s Dr. “These are important,” Howarth said.

Amy Townsend-Small, an associate professor of environmental sciences and an expert on methane emissions at the University of Cincinnati, said that more scientists are starting to examine some industry claims about hydrogen, just as they are examining the climate effects of natural gases. gas production. “I think this research will move the conversation forward,” he said.

Plans to produce and use hydrogen are progressing. In conjunction with National Grid, Stony Brook University and the State of New York, While the project aims to produce hydrogen using renewable energy, it seeks to integrate hydrogen into existing gas infrastructure.

Plant spokesman Jerry Nappi said Entergy believes hydrogen is “part of creating a long-term carbon-free future” and uses renewable energies such as wind or solar to generate electricity only intermittently. “Hydrogen is an important technology that will enable utilities to adopt much higher levels of renewable energy,” he said.

National Grid cited its net zero plan, which says hydrogen will play an important role in the next few decades and that generating hydrogen from renewable energy is key.

Kate T. Muller, spokesperson for the state’s Energy Research and Development Agency, said New York State is “exploring all technologies” to support its climate goals, including hydrogen. Still, its researchers “will review and evaluate the blue hydrogen paper,” he said.
