Improve Energy Efficiency Using Heat Pumps

Heat pumps are an efficient way to provide space and process heating. Information on their types, and how to assess their potential benefits is provided here Approximately 40% of the energy that is used in buildings in the U.S. goes…

This heat battery is a decarbonized, ‘drop-in’ replacement for industrial boilers

As the cost of renewable energy decreases, many organizations are looking to electrify their operations to reduce carbon emissions. One promising area for decarbonization is industrial heating, which accounts for a large fraction of global emissions. However, heating networks in…

Solar clinker produced for the first time

Last month, Cemex, S.A.B. de C.V. (Cemex; Monterrey, Mexico; www.cemex.com) and Synhelion SA (Lugano, Switzerland; www.synhelion.com) successfully connected the clinker production process with the Synhelion solar receiver to produce solar clinker. The milestone is a first step towards fully solar-driven…
