Green hydrogen – energy storage
Actor network theory or ANT described by Bruno Latour can be used to understand why the world thought hydrogen was a critical part of carbon emissions reduction to mitigate climate change. Turns out that the black box of Hydrogen is a myth. Based on faulty science, supported by subsidies to support existing fossil fuel companies. Thankfully is dying as the box is exposed.
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.
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 CEO. Despite Carolos Tavares says in an online event that the cost of hydrogen mobility is ‘sky high’, just two months after introducing eight new H2 van models.
Will Australia be a hydrogen superpowre and is the vision fantasy or reality. The absolute physics suggest that Australia can use its vast area and high sunlight for adding value to exisiting exports of iron, aluminium and minerals.

Dr Paul Martin, a 30 veteran in the hydrogen engineering business distills his hydrogen thoughts into a Linkedlin Article. This post attempts to summarise his 30 plus articles to the key essence. Hydrogen is not a fuel.
A credibility gap exists between stated Hydrogen suse and progress to date. Michael Liebreich terms this missig trillions of investment needed to achieve the goals.
Real world examples where hydrogen fuel cell buses and transport systems have been deployed as “trials” and abandoned due to high costs and reliability.
Will the decrease in the cost of hydrogen electrolyzers be sufficiently fast to compete with other energy solutions? Will China drive the cost down fast enough?
The passage of the IRA bill was enabled by politics and putting in expenditure to placate fossil fuel states and representatives. The $7 billion for hydrogen trucks is an example of sheer folly, but political necessity
Buses powered by Hydrogen are in the headlines – as the hydrogen industry try to muscle into the electric bus industry, With less than 0.1% of the global bus market – are they destined by by the BETA of tapes in 5 years?
Germany introduced hydrogen FCEV trains from 2018 in Frankfurt and Saxony areas. LNVG as now gone to tender for over 100 all battery electric as hydrogen too expensive and H2 trains termed “misery trains”.
Green steel produced by direct reduction is likely to have metallurgical coal become a stranded asset, as cost reductions and increasing technology improvements to make green steel viable.
Sophisticated modelling shows hydrogen for home heating is a non starter except in a few use cases and heatpumps and batteries provide a more effective solution to home energy use.
Hydrogen for transportation won’t die, and the big 4 Japanese motorcycle manufacturers have joined together to develop hydrogen engines for motorcycles. But Why?
Is Hydrogen like a cult? Hydrogen cult madness? Proponents claim that H2 will solve the renewable energy transition challenges but the science evidence it wont.
Hydrogen fuel cell cars are still promoted but they will be dead within 2 years due to emissions as bad as petrol cars, poor infrastructure and rapid improving charging and range with battery electric cars.
