RIFT is developing a technology that use iron powder as a circular fuel to generate heat with no direct CO2 emissions. This circular fuel is a sustainable alternative to fossil fuels. Iron powder is used as a medium to store energy, when this is combusted, heat is created and the residual powder, iron-oxide (aka rust), is regenerated into iron fuel which can be used to create heat again (and again and again). RIFT is developing industrial-scale boilers which will directly replace gas-fueled boilers and save thousands of tons of CO2 emissions per year.
