A study of a 30 MW wind hydrogen project in Ireland puts annual value added at €71.2 million or €81.3 million depending on the value chain, yet the end use prices in its tables imply hydrogen sales of only €30 million to €38.5 million, and the GDP figures differ between abstract and text.
A Journal of Energy Storage study of a battery thermal management system with a pulsating heat pipe, fans and capacitors reports preheating a lithium-ion module from minus 30 °C to 0 °C in at most 461 seconds and holding hot modules within 2 °C.
A 2030 optimisation study of five shipped fuels finds electricity is at least 41 percent of every delivered cost, shipping is minor even over 10,000 km, and liquid hydrogen needs about 76 times the shipping capex of ammonia per MW.
A Journal of Energy Storage review of seven mature grid storage technologies reports pumped hydro at 201 GW in 2025, over 94 percent of global capacity, with round trip efficiencies running from 42 to 87 percent across the plants it describes.
Chinese state media say the hydrogen industry is moving from pilots to scale, yet Baotou’s 7,800 tonne green hydrogen project is 0.02 percent of the 39 million tonnes China produced in 2025, and Inner Mongolia’s 12,694 tonnes is 0.03 percent.
Daejeon’s 38.8 km hydrogen tram, billed as the longest catenary free line in the world, is now expected to open in 2030 instead of 2028, while Ulsan’s 10.85 km first section carries the first proof point in 2029.
A Journal of Energy Storage paper turns electric vehicle battery signals into text for a language model agent that diagnoses faults and drafts maintenance advice, tested on ten vehicles and judged by three experts, with accuracy figures not given in the abstract.
A review in the International Journal of Hydrogen Energy puts the room temperature hydrogen capacity of metal organic frameworks generally below 1 wt%, against a US DOE on-board system target of 6.5 wt%, and flags the gap between powders and prototypes.
Global X launched an SMR ETF of about 15 companies whose top 10 holdings carry 97.8 percent of the weight, as the IEA scenario of 1,000 SMRs by 2050 would need about $670 billion of cumulative investment against about $5 billion a year now.
The average daily gap between the highest and lowest priced hours in the UK rose 80 percent to about £123 per MWh in September, as Europe’s roughly $40 billion battery fleet heads into a winter that will test whether more batteries mean less per battery.
