Green hydrogen may not be green. Blue hydrogen may be worse than other hydrogen colours if the methane gas has leaks. Depending on the source of methane, electricity the climate change emissions of hydrogen varies by source, electrolyser efficiency, carbon capture and storage efficiency. The life cycle analysis needs to be done on all hydrogen projects to see how they can reduce carbon emissions.
Hydrogen itself is not a direct greenhouse gas, as it does not absorb infrared radiation. However, evidence suggests it acts as an indirect greenhouse gas. When released, it extends methane’s atmospheric lifetime, increases tropospheric ozone, and adds stratospheric water vapor, all of which contribute to warming. Studies estimate its 100-year Global Warming Potential at 11.6 ± 2.8.
Hydrogen will be an essential fuel for the zero emissions economy says Dr Andrew Forrest in an interview on Cleaning Up Eps 210. With a 80% reduction in size, and an increase in efficiency to 96%, green hydrogen ammonia will move ships and enable green steel.
Geologic or gold hydrogen has potential to be part of the clean energy transition. Potential LCA and cost is low ($1kg), but there are technological and economic hurdles Co-production of helium with geologic hydrogen could be a key factor in making this technology commercially viable.
Research and development may determine the true potential of geologic hydrogen.
Rapid electrification is forcing gas network companies to seek higher fees by over $200m as they try to protect over $10 billion of stranded assets. As more households switch to electricity, the future of renewable gas remains uncertain. The energy transition challenges policymakers to protect both consumers and gas companies.
Renewables can supply 100% power, with several countries already achieving high percentages. They are cheaper than fossil fuels, despite rising energy bills due to external factors. While land use is less for renewables, the environmental impact of fossil fuels is significant. Job transitions from fossil fuels to renewables are underway, with potential growth in sectors like battery technology. Renewables offer economic, environmental, and job benefits over fossil fuels.
Recent publications show a 3°C climate change costs 36% of GDP or $56 trillion. That is like the depression of […]
China is a good comparison of hydrogen fuel cell vehicles. In Foshan city an H2 tram has been mothball and when you look at all cars and public transport, it is hard to see where the use case for hydrogen is.
Previously we outlined ten reasons hydrogen was dead for transportation, yet we see Stellantis flawed hydrogen strategy proposed by the […]
Electric vertical takeoff and landing craft – a combination of helicopter and airplane are coming in 2025 as production and regulations are met. Piloted, 4 seater aand first focus is cross city Uber style from downtown New York, Chicago, Los Angeles to the airport. Joby and Archer are well funded to be sucessful
