    What are the waste products from burning hydrogen?



  • Registered Users, Registered Users 2 Posts: 23,261 ✭✭✭✭Akrasia


    yes, the emissions from burning hydrogen are :Water vapour

    If hydrogen is produced using renewable energy then burning hydrogen is very environmentally friendly

    I know him from old. Maybe not so much pushing a united Ireland, but for the rest it`s entirely possible. Especially if there is a blue tinge to the policy

    The amount of public debt per person is greater than in Greece. Massive anything is financial irresponsibility we can't afford, particularly when every wannabe EV charriot driver wants zero taxation on them and no doubt a generous subsidy to boot.

    I wonder if there is any process where we can create hydrogen and the exact right amount of oxygen required to combust that hydrogen at the same time.......

    Is this process cleaner than burning coal/gas/oil?

    would burning green hydrogen be an improvement on what we do now?

    What about making it? Is it highly energy intensive?

    So you're shifting the goalposts then. Yes it takes energy, but the point of offshore wind, is that it has a very low marginal cost, and is zero emissions at the point of generation, so even if the end to end efficiency is 50%, its still worth doing

    We already store lots of explosive chemicals and transport them routinely with very few explosions, and compared to the danger associated with fossil fuel production, have you not seen the danger from offshore oil and gas explosions, and the environmental devastation caused by oil leaks to vast areas of our natural environment?

    It takes a lot of electricity to convert water to hydrogen (and oxygen), but the process is about 80% efficient, so really the cost to create the hydrogen is about 20% of the energy used (there are some other costs to do with calalysts and operating the plant required and the water needs to go through Seawater reverse Osmosis before processing it, but these are relatively small in terms of energy and operating costs)

    The thing about wind power though, is that due to the way the grid operates, wind turbines often have to be turned off to avoid overloading the grid, so a lot of the energy generation capacity is wasted, and the grid actually pay turbines to Not generate any power for these periods.

    If the turbines could be used to generate hydrogen during the times when they would otherwise be doing less than nothing, then the electricity is essentially free which makes the process much more economically viable

    You said there is an oxygen shortage due to covid, producing hydrogen from H20 creates pure oxygen as part of the reaction so there is no net increase in the demand for oxygen even if all of the green hydrogen was being burned in a electricity generating facility, or in an industrial plant for thermal processes, which can be configured to burn the hydrogen in a pure oxygen environment

    Not all the green hydrogen would be intended to be burned, it could also be used in Hydrogen fuel cells which have no NOX emissions

    Grid level fuel cells are existing technology which can be rolled out as the price and availability of Hydrogen falls, these do not need pure oxygen as they can take ambient air for their reactions

    And there are options for transporting Hydrogen in more stable forms, as was mentioned in this thread already, Hydrogen can be combined with Nitrogen to make Ammonia, and this can be liquified and transported and stored much easier than liquid hydrogen

    We already transport volatile and dangerous chemicals vast distances, process them in filthy refineries and ship them all around the world to use in power generation and industry. You need to make an argument that green hydrogen is more dangerous, more polluting, and more process intensive than the end to end fossil fuel process instead of just throwing out objections, and then moving on to another one whenever the old one is addressed.

    The Honda Clarity and Toyota Mirai have fuel cells and only emit water. I believe most hydrogen buses also use fuel cells.

    Oh not that acid rain BS again. I remember reading about how the Black Forrest in Germany would have ceased to exist by now due to acid rain.

    "Remember the big “acid rain” scare during the 1970s and 1980s attributing damage to lakes and forests to emissions from Midwestern utilities? If so, did you ever hear the results of a more than half-billion-dollar, 10-year-long national Acid Precipitation Assessment Program study that was initiated in 1980 to research the matter?

    Probably not.

    As it turned out, those widespread fears proved to be largely unfounded, since only one species of tree at a high elevation suffered any notable effect, and acidity in lakes was traced to natural causes. The investigating scientists reported that they had “turned up no smoking gun; that the problem is far more complicated than it been thought; that other factors combine to harm trees; and that sorting out the cause-and-effect was difficult and in some cases impossible.”https://www.forbes.com/sites/larrybell/2014/02/11/remember-the-acid-rain-scare-global-warming-hysteria-is-pouring-down/?sh=763656de53fc

    Most pollution alarmism is hype. I also remember the melt downs in the media every time there was a major oil spill. Eco systems ruined for all eternity - except they weren't, because it turns out that bacteria love oil for breakfast, lunch and dinner, and the negative impact on ecosystems termed out to be transitory. I'm not in favour of oil spills in the slightest, they are bad and to be avoided at all costs, but I am in favour of the truth over scare mongering, such as with AGW.

    He also claims that offshore wind turbines are cheap, its pretty obvious that many Green supporters have no concept of money, there's one poster looking for a €40billion bailout of the Irish motor industry ffs.



  • Registered Users, Registered Users 2 Posts: 23,261 ✭✭✭✭Akrasia


    I am advocating using Hydrogen generated using wind turbines as a store of energy, It can either be burned to turn a turbine, or used to generate electricity in a fuel cell. BOTH of those can be done without creating any NOX emissions

    You said pure oxygen is scarce, you have ignored the fact that creating the hydrogen will create as much hydrogen as they need to burn that hydrogen in a pure oxygen environment.

    https://www.sciencedirect.com/science/article/pii/S1876610212014233

    There is no technological barrier to creating clean energy from Green Hydrogen. It just requires the investment

    so you advocate storing the oxygen as well as hydrogen created by electrolysis?

    How do we transport this oxygen? A separate pipeline infrastructure across the country?



  • Registered Users, Registered Users 2 Posts: 23,261 ✭✭✭✭Akrasia


    Fuel cells don't need pure oxygen to work, and fuel cells do not produce NOX when the oxygen is supplied directly from the atmosphere

    While the capital costs are high and there are maintenance costs, there is no fuel cost, so the marginal cost of producing electricity is very low.

    Because it's quick and cheap for wind turbines to turn themselves on and off, while switching off Coal or Gas turbines is expensive and takes hours, the grid management company often instruct wind turbines to shut down because the fossil fuel plants are generating enough power and they don't want the system to get overloaded

    This represents a lot of wasted energy, that the turbines could be generating, at almost no cost. What green hydrogen production would do, is take the extra capacity so instead of shutting the turbine down, that energy gets used to generate hydrogen and oxygen that can be sold later when there is a greater demand for fuel.

    The grid will no longer have to pay the operator to not produce electricity, and the operator will be able to profit from selling a valuable energy source, and the grid will be able to benefit from having more energy security if we build the infrastructure to generate electricity from this hydrogen (that will happen either through private or public investment)

    You have no concept of money. You're only comparing one side of the balance sheet. A 21st century grid will be cheaper than the 20th century one we're trying to move away from

    But even if it was more expensive, the environmental cost of climate change would justify spending a lot more money on sustainable energy to avoid the worst impacts of climate change

    They can store the oxygen, or vent it, if it makes sense to store it, they'll store it, if it is cheaper or more efficient to produce it somewhere else, they can do that.

    We could use a pipeline across the country, or tankers, or a herd of flying unicorns. Or they can generate the oxygen they need nearby and pipe it to the plant

    I'm not going to be designing or operating the system. There are already large scale industrial activities that use large volumes of pure oxygen working happily all around the world and they've figured it out. I'll let the experts design the system according to the specifications that make most sense to them.

    Once the regulatory environment is established, and emissions are properly measured and regulated, one of the few benefits of capitalism, is that there are countless highly skilled specialists and engineers who can implement almost any solution as long as we have the technology and the proper financing and infrastructure.

    How? 50% plus unemployment and every second house using candles and burning broken pallets because electricity isn't affordable?



  • Registered Users, Registered Users 2 Posts: 13,503 ✭✭✭✭Mad_maxx


    Money is easily found and EVs is a form of infrastructure spending within context of green economy

    Catherine Martin getting savaged on Saturday with Katie Hannon. Mother of god, she's living in cuckoo land.

    Apparently Eamonn Ryan (if he can stay awake long enough) is making 2 announcements later at the Greens Virtual Conference, increasing Grants Apparently one of them and of course that going to really help those who want to retrofit whilst barely able to heat their homes.

    id put money on reaching a million EVs far quicker than reducing the national herd by even a tiny amount , one is politically near impossible and its not the former

    Savaged is the word! You can even hear it in her voice that she is unsure of what she is saying.

    It's just extraordinary, she's now rabbiting on about grants for the Panto Sector , if I recall a certain cohort only got these grants last year I won't mention names, but Virgin Media comes to mind.

    She's all over the place , barely able to answer very simple questions on green policies, let alone questions on her ministerial brief 🙄
