It looks to me you just hate fossil fuel companies. Which is fine. But if they can help to get sooner at net zero, you'd rather say no? Hydrogen can produce NO

Hydrogen can produce NOx when burned, if you burn it in air. You can burn it in flue gas (a combination of pure oxygen and CO2). Or you can simply use it in fuel cells to produce electricity.
To me the main issue with this discovery that that this "large deposit" is not nearly large enough. At the high end of the estimate it would be 250 million tons of H2, which would replace about 600 million tons of CH4, which would result in about 1.5 gigatons of CO2. That's a lot, but we emit about 50 gigatons of CO2 equivalent each year. We'd need many hundreds of these fields to make a significant dent in our emissions.

- c_o_n_v_e_x 3y agoAh, interesting, never come across that before. All the process equipment I've worked with (boilers, furnaces, etc.) combust fuel with ambient air.
