Renaissance Fusion aims to build a stellarator fusion reactor - which is different to more commonly used tokamak designs - by developing two innovative technologies. The 1st technology concerns the use of liquid metal, which sticks to the inner walls of the reaction chamber & insulates them from extreme heat & radioactivity (with lower maintenance costs). Currently, the startup can create liquid lithium-based walls 1cm thick, but significant development remains before they can be used in nuclear fusion, which requires a thickness of 30-40cm. The 2nd technology relates to high-temperature superconducting coils, which generate strong(er) magnetic fields (& potentially allow a smaller reactor to achieve the same performance as a larger one). To do so,...

Every known method of shipping hydrogen (H2) has its drawbacks: i) Compressed H2 has very low energy density by volume, ii) Liquid H2 requires storage at temperatures of -253°C, iii) Ammonia as well as methanol (which can be decomposed/ cracked over a catalyst to produce H2) have higher volumetric energy density, but the former is extremely toxic & the latter costly to produce, iv) Liquid Organic Hydrogen Carriers (LOHC) (from fossil fuels) require (energy-intensive) high-temperatures to release the H2 (upon delivery). So, what if there was a way of storing hydrogen in a low-cost, non-toxic, non-explosive substance, that is a liquid at ambient temperatures & pressures and requires no energy – only the addition of...
