BP Teesside hydrogen hub

By Ian Page BP announced that alongside their 1GW of blue hydrogen production planned for Teesside. They intend 500MW of green hydrogen, which with a network of filling stations , and an agreement with Daimler trucks is enough for 32,000 trucks. There are some obvious questions. Where are they going to get the methane from for the blue hydrogen, where are they going to sequester it, and how confident are they that the cost of their main input which is  natural gas is going to get cheaper , since it now costs more to use natural gas than electrolysis. ( and Asia generally has a large deficit in natural gas and is buying the LNG that BP would need. BP has a large LNG output from Australia, but they can probably get more for it from Asia and China, and anyway why not process it to Hydrogen in Australia and sell the hydrogen to Singapore (one of the projects being discussed).  The next obvious question is where are they going to get the electricity for electrolysis. If it comes fr...

REN: Lithium- US challenge to get DLE working

by Ian Page https://www.nrel.gov/docs/fy21osti/799178.pdf There are lots of deep rock brines in the world, in particular under the Salton Sea in California. These contain between them an enormous amount of lithium. DLE direct lithium extraction is an approach to put an extraction plant at the cool output of a geothermal plant before the brine is returned to the ground. The lithium process gets the drilling and pumping essentially for free which improves the costs. (As well as some low temperature hot water that might be useful in the processing.) The main problems are separation of the lithium from all the other junk and ensuring that the brine that comes up the bore hole doesn't lose lithium concentration because the way brine being returned has no lithium in it. The above paper suggests that it should be commercially feasible, and a challenge has been set up to demonstrate feasibility in two years. It should be faster to implement the results of this than to create a new lithium ...

REN: EV's happing faster than forecasters thought

 by Ian Page https://cleantechnica.com/2021/07/22/ernst-young-electric-cars-are-coming-sooner-than-expected/ A notable feature of exponential change and tipping points is that even those who think they understand them find themselves continuously upping their forecasts. Ernst and Young - never one to ignore  a consulting gift horse - have dived in  with an "AI forecasting system". However the main points here are... The current market shares of EVs around the world  are getting serious (which agrees with all the stuff I've been reading. E.g. over 50% of leasing in some areas being EV's - take the up front capital cost out of the equation and the running costs win out even now). The fun little video they offer which is obviously intended to convince clients that they have to move now and that EY can tell them what to do.
