An interesting suggestion by the article I.e encourage the wind power owners to instead of curtailing power generation and receiving money for not producing anything, to continue generating power for hydrogen purposes. Great idea, just how can that work in practice? If the grid is saturated and the power needs to be curtailed, unless the electrolyser has a private cable connection to the wind farm or is sitting right at the foot of the farm, the power cannot be channelled to grid connected H2 projects. Plus one of the major cost elements of H2 production is the price of green electricity, sometimes accounting for more c.60% of LCOH. So for the proposition to use the curtailed power in H2 projects to work, Not only would it need more grid connection capacity or private connection to the H2 projects, but also the power cost will still need to be subsidized or the power sold at a very low price to make H2 competitive. Still, a good idea worth exploring. #hydrogen #greenhydrogen #co2reduction

We must remember the Basics Large Coal fired power plants are best operated at their optimum loading points for efficiency and lowest cost. The Grid has a threshold of minum load with fluctuations during the day/nite. Here baseload cheap coal fired power plants played a crucial role. Gas peakers helped with the peaks. With a green economy, we will need large scale industrial processes. These will need reliable, base power. There will be more fluctuations above this as we have CER's - consumer energy resources - those pesky unidentifiable power sources to the Grid. Soon we will have every energy source or consumer with unique ID's visible in a digital platform - the energy internet! Now we have variable renewable energy #VRE and #variable load demand! Thanks to the liberation of consumers to have their own cheap source of clean energy - roof top solar as an example. Wait till we have V2G EV's!! As we had coal mines and gas well for storage to underpin the fossil fuel generators for dispatchability, we need LDES to firm up VRE's to act the same. LDES is not 2-4 hours BESS! Yes Grid stability is reliant on system inertia, amongst other factors, which large heavy rotating generators provided. Modern smart inverters can provide virtual inertia and so can synchrons. But we also have reciprocating engines and gas turbines that can run on #greenfuels in the near future -this pathway is happening with GE, MAN and Mitsubishi. So let's get these basics right- variable or not, all generators need long duration energy storage #LDES to provide the #reliable power we all want and need. As we have changed the fuels to steam generators and gas turbines, we can change again but using zero carbon fuels. Expensive - yes, for the short term until demand creates innovation to reduce costs - no different to what we had historically. If you add the "cost" of carbon- it's an even more weak argument. If you don't put a price on carbon, then you are not acknowledging climate change- so why bother transitioning? I hope I have raised a few questions or challenges?? DM me for a discussion. Happy to hear different views!

https://lnkd.in/eX2EWj-j One more blow to hydrogen hype and hopium. Hydrogen-ready' gas turbines are not a meaningful climate solution. Think-tank IEEFA warns that many projects do not schedule H2 use for years, while the scale of supply would require billions of dollars of investment for meagre climate benefits. The renewable electricity required to generate green Hydrogen to burn in these turbines is so huge that it is unlikely to materialise. #hydrogen #gasturbines

Dilip Patel, Green Hydrogen will never be an economical efficient and not even be a green solution! "When green Hydrogen is combusted with atmospheric air (78 % N2) it produces 2.5X à 3X as much NOx + H2O => HNO3 => Nitric Acid precipitations on nature and planet earth`s soil as CH4, etc. and yes Green H2 does not produce CO2, the valuable Gas of Life! However to repeat; Green Hydrogen produces 2.5X à 3X NOx + H20 => HNO3 => Nitric Acid precipitations as much as combustion of CH4 with atmospheric air (78 % N2), CH4 of course produces valuable CO2, the Gas of Life! Regards from Hulst, the Netherlands.

"Hy Stor is among the #hydrogen companies and #renewableenergy developers that have sent letters supporting the rules as proposed. A March 1 letter to #Treasury and #WhiteHouse officials from companies including Hy Stor Energy says: “Clear section #45V guidance that upholds the three pillars is necessary to guard against harmful climate impacts and significant #emissions increases that might be driven by increases in fossil fuel-based generation to sustain #electrolysis when #renewablegeneration sources are not available. Weak section 45V rules would permit this perverse result, thus imposing significant climate and #marketrisk that would undermine the achievement of U.S. #climategoals, further the perception of #politicalrisk in U.S. #climateregulation, and upset the hard-won momentum currently driving #investment in the sector.” That letter was also signed by renewable energy developers CWP Global and ACCIONA, ACCIONA affiliate Nordex Green Hydrogen, major hydrogen producers Air Products and Synergetic, geothermal energy provider Fervo Energy and others..." https://lnkd.in/g9Ged85Q

A good number of countries, especially the ones whising to abandon #NuclearPower are looking to low-carbon gases like #Hydrogen to replace the functions gas meets now... But is it really so simple??? Obviously the ptential to replace #Natural gas is there, but #HydrogenLobby is missing some of the significant challenges and considerations such as: ♦ #InfrastructureRequirements: Replacing natural gas with hydrogen would require substantial modifications to existing infrastructure, including pipelines, storage facilities, and appliances, because hydrogen has different properties such as lower energy density and higher reactivity. ♦ #Cost_And_Efficiency: Currently, hydrogen production, especially green hydrogen, is more expensive than natural gas. Additionally, the processes to convert and transport hydrogen can be less efficient, though technological advancements are expected to improve this over time. ♦ #Blending_With_NaturalGas: In the short term, hydrogen can be blended with natural gas in existing pipelines, reducing carbon emissions while using current infrastructure. However, for full replacement, more significant changes would be needed. ♦ #LongTermVision: Hydrogen could play a key role in a decarbonized energy future, particularly in sectors where natural gas is hard to replace, like industrial processes and heating. However, its widespread adoption will depend on advances in production, storage, distribution, and cost reduction. Let's not make the same mistake with #Hydrogen as with #Renewables!!! Neither of them are yet ready to sustain the #EnergyTransition!!!

More government support and incentives are needed for a global clean hydrogen market to develop. Still, despite the obstacles that have emerged over the past few years, industry executives believe this will happen — it just may take more time than initially anticipated. In fact, some liken these early days for hydrogen to those of other renewable energies like solar and wind, which were also dependent on regulation for market development but can now compete on their own.

Some sensible suggestions in this report. Which is what you'd expect when it's backed by LCP Delta analysis 😉 https://lnkd.in/ee_frtsv "Through modelling conducted with LCP Delta, the report determines that electrolysing the UK’s wasted renewable energy could create enough hydrogen to displace two-thirds of the 700,000 tonnes of the UK’s current, carbon-intensive grey hydrogen consumption annually;" Linking constraints on wind generation to hydrogen production, and ensuring some industrial demand as offtaker is sensible when thinking about the size of potential curtailment in the 2030s. #hydrogeneconomy #energy

We wrote our first article on the UK's problem of 'curtailment', and how hydrogen can help solve it, back in November 2022. This week a new report suggests further practical solutions for the UK's excess wind power dilemma, that could also accelerate the UK's hydrogen industry whilst potentially saving us billions annually. The study by London think tank Policy Exchange highlights the mismatch between the nation's advanced wind turbine fleet and its struggling electricity grid. This inefficiency leads to substantial curtailment fees paid by the government to wind farm owners. However, by using excess wind power to produce green hydrogen, the report proposes a dual benefit: resolving the current grid challenges and accelerating the hydrogen sector. The report also emphasises the growing importance of boosting the UK's low carbon hydrogen production capacity, with hydrogen projected to contribute so significantly to Britain's final energy consumption by 2050. #WindPowerOptimisation #GreenHydrogenSolution #RyzeHydrogen #EnergyGridEfficiency #LowCarbonTransition #HydrogenSectorInsights

#Netzero hydrogen plans may not offer value for money — Blending hydrogen into gas grid may raise bills, say campaigners, as Government admits costs are unknown Net zero plans to blend hydrogen into the gas grid may not offer value for money, the Government has admitted. The Government is due to make a decision this year on whether to support blending 20 per cent hydrogen in the gas grid, as a way to boost the fledgling net zero industry. But a consultation document says it is not yet possible to know whether such a move would be “value for money” because is it “not currently feasible to quantify theoretical additional costs” of blending. Among the unknown costs are potential updates to the gas network pipes before 2025 and changing of gas meters to ensure they are safe and capable of carrying hydrogen. The Government has targeted 10GW of low-carbon hydrogen production by 2030, from almost none currently, including green hydrogen created from excess renewable energy. #greenhydrogen producers The blending policy is intended principally to help provide a guaranteed income stream for green hydrogen producers to support the development of the industry rather than to cut emissions from heating directly. A blend of 20 per cent hydrogen is only estimated to cut carbon emissions by 6 to 7 per cent. #hydrogenstrategy
