Researchers Develop More Efficient Thermocells for Low-Grade Waste Heat Recovery

Green Car Congress

Research on utilizing low-grade heat from sources such as industrial waste streams, geothermal activity, and solar heating has focused on using solid-state thermoelectrics and Stirling engines to harvest low-grade waste heat as electrical energy. In fact, it was previously predicted that a power conversion efficiency of 1.2%

Lifecycle Study Finds Algae as Bioenergy Feedstock Has Higher Environmental Impacts than Conventional Crops in Energy Use, GHG Emissions, and Water Use; The Importance of Using Waste Streams

Green Car Congress

Model scope includes all upstream processing of biomass material; conversion to liquid or solid fuel is intentionally excluded. Biofuel conversion processes were excluded from the scope of the analysis. These so-called ‘indirect’ changes are associated with conversion of arable land into production and were not included here.
