Asegun Henry is an associate professor in the Department of Mechanical Engineering at MIT where he directs the Atomistic Simulation & Energy (ASE) Research Group. His primary research is in heat transfer, with an emphasis on understanding the science of energy transport, storage, and conversion at the atomic level, along with the development of new industrial scale energy technologies to mitigate climate change. Prof. Henry has made significant advances and contributions to several fields within energy and heat transfer, namely: solar fuels and thermochemistry, phonon transport in disordered materials, phonon transport at interfaces, and he has developed the highest temperature pump on record, which used an all-ceramic mechanical pump, to pump liquid metal above 1400°C. This technological breakthrough, which is now in the Guinness Book of World Records, has opened the door for new high temperature energy systems concepts, such as methane cracking for CO2 free hydrogen production, and a new grid level energy storage approach affectionately known as “Sun in a Box,” that is slated to be cheaper than pumped hydro.
