Tesla’s iconic cybertruck considers a retractable solar panel that can boost its power for longer range.  R&D has been improving the efficiency and durability of solar pv. There are works around flexibility solar material and even solar paint. Maybe the era of solar car might never come but solar technology makes EV possible with with cheap and clean fuel. So is solar/electric hybrid the way to go for countries like Australia? 

Converting retired coal plants to hydrogen (blue and green) producers and peaking generators seems a good option. Some coal plants could be forced out of the market earlier than their technical lifetime given the uptake of both large scale and distributed renewable energy. They could reuse their core parts and transmission infrastructure for brownfield hydrogen plants. https://www.h2-view.com/story/retired-new-mexico-coal-fired-plant-to-be-repurposed-to-hydrogen/?

German companies and researchers, led by MAN Energy Solutions, are working on a medium speed engine that can burn both diesel and ammonia. Ammonia is made from hydrogen through the Haber-Bosch at industrial scale and is a better energy carrier than hydrogen due to its high stability and energy density. An ammonia engine makes it possible to direct use of ammonia as power fuels by the transport sector for higher energy efficiency without converting it back to hydrogen.  https://www.offshore-energy.biz/man-energy-kicks-off-ammoniamot-project/

Australia will see the first hydrogen-powered heavy vehicles on the road in nine months. Coregas will purchase two hydrogen trucks and build a refueling station in Port Kembla NSW. This project is supported by NSW Government after the announcement of $740 million funding boost to build the foundation for new net-zero industries and transit heavy emitting industries. Higher energy density makes hydrogen more preferable for transferring large loads and long distance compared to electric vehicles. This means we will see hydrogen trucks, regional buses and trains carrying the heavy lifting to decarbonise freight sector. https://www.drive.com.au/news/trucks-likely-to-lead-the-way-with-hydrogen-power-124557 

These MechanicalTreesTM are passive direct air capture technologies that absorb the CO2 rather than sucking them out of the air. The 150 sorbent tiles of a 10 meter tall mechanical structure can be fully saturated with CO2 in 20 minutes and go through the standard scrubbing process after retracing into a chamber. Some blue sky thinking but would it be great if we can make these mechanical trees as retractable wind towers for offshore hydrogen production? You will have the green hydrogen, negative carbon plus smart offshore wind farms can survive extreme weather to battle climate change. https://mechanicaltrees.com/mechanicaltrees/ 

ERM’s Dolphyn (Deepwater Offshore Local Production of HYdrogeN) project is exploring offshore hydrogen production option - a 10MW floating wind turbine with built-in electrolyser will convert sea water into green hydrogen. There is no water constraint, no electricity grid connection issue and the hydrogen can be shipped out by ammonia-powered vessel soon (EU’s ShipFC project)? https://www.theengineer.co.uk/erm-dolphyn-green-hydrogen/
