Great work as always! After speaking with a somewhat similar company (Rondo Energy) it opened my eyes to the world of industrial heating needs. I asked them at the time about phase change materials (PCM), due to the high specific heat capacity available, but they said it was less suited to their applications due to the higher temperatures they operate at (1000K +). Really interesting to see a company combining the advantages of bricks and PCMs! I am interested to see what portion of MGA's use cases will be for electrical vs thermal power output - Rondo were very focused on thermal output (mainly for cement), but I guess if the renewable power is really surplus to requirement this cheap 30% storage efficiency can make sense. It just strikes me that we are better off trying to load shift applications where possible, but I always welcome as many solutions to a problem as possible at the end of the day! The direct use of heat is also just very satisfying due to the cheap 95%+ round trip efficiencies it offers!

Great insight as always Rosie :D It is often easy to look at projects short term and not consider how useful they will be as part of the bigger picture. Many clean energy projects could benefit from doing a 'minimal viable product' to test technical challenges much earlier than they currently are!

Great video Rosie! Loved the analogy and glad to see the video is doing so well given all the time this must have taken :D

Great video as always Rosie, very jealous you got to drive around the polestar! Loved the combination of engineering information with the story of your trips and real world challenges of the charging network. Also, you have very interestingly named placed in Australia!

@4drops Apologies if the comment wasn't clear, but my point was two fold. Firstly, that people generally look at projects in isolation, but forget that they are smaller parts of a bigger plan. In this case, it is likely that this project will show liquid hydrogen is not worth pursuing, but the fact it comes from black hydrogen gas is not really the point imo, hence we need to consider the bigger picture of what the project is actually trying to do! And secondly, there are some projects that want to use "clean technology" to solve a problem and they attract millions of dollars of funding before they have done a 'quick and dirty' minimum viable product, which in some cases could show the whole idea is unfeasible anyway and save a lot of investors money!

@adrianthoroughgood1191 This is very true, sadly! You would hope people would want to try an idea and move on if it wasn't feasible to start a new project that could actually work! But I think you are right, often that is not peoples incentive...
