MIT/Stanford team develops battery technology for the conversion of low-grade waste heat to power; TREC

Green Car Congress

Researchers at MIT and Stanford University have developed new battery technology for the conversion of low-temperature waste heat into electricity in cases where temperature differences are less than 100 degrees Celsius. converting heat to electricity. C, which accounts for a large proportion of potentially harvestable waste heat.

Researchers Convert Green Tide Macroalgae to Bio-oil

Green Car Congress

Researchers at Fudan University (Shanghai, China) have converted the marine macroalgae Enteromorpha prolifera , one of the main algae genera for “green tide”—massive algal blooms caused by eutrophication of marine water bodies—to bio-oil by hydrothermal liquefaction in a batch reactor at temperatures of 220-320 °C. and Enteromorpha sp.,

Biomass fuels: challenges and opportunities – ET Auto

Baua Electric

The term ‘biofuels’ encompasses solid, liquid, and gaseous fuels primarily derived from biomass, including animal and plant wastes and residues. Biomass can be converted into fuels through several steps. Carbon dioxide cycle of biomass-based fuels. The schematic of biomass to ethanol production is shown in Figure 2.

NEC, NEC TOKIN and Tohoku University develop spin-Seebeck thermoelectric device w/ 10x better conversion efficiency

Green Car Congress

Thermoelectric conversion technology that converts energy abandoned as waste heat back to electric power is strongly anticipated to be used for saving energy and reducing greenhouse gas emissions. This is a phenomenon in which a temperature gradient applied in a magnetic material produces a spin current along the temperature gradient.

Modified enzyme can increase second-generation ethanol production

Green Car Congress

One of the main challenges of second-generation biofuel production is identifying enzymes produced by microorganisms for use in a cocktail of enzymes to catalyze biomass hydrolysis, in which the enzymes act together to break down the carbohydrates in sugarcane trash and bagasse, for example, and convert them into simple sugars for fermentation.
