USDA closes on $105M loan guarantee to Fulcrum for biorefinery converting municipal waste to renewable jet fuel; first USDA loan for biojet

Green Car Congress

Fulcrum will gasify 147,000 tons of municipal solid waste to produce synthesis gas which it then will catalytically convert to synthetic paraffinic kerosene/jet fuel via a Fischer-Tropsch (FT) process. A venturi scrubber captures and removes any entrained particulate, and the syngas is further cooled in a packed gas cooler scrubber.

Audi testing find e-ethanol and e-diesel produced by Joule often perform better than conventional counterparts

Green Car Congress

Audi investigating its e-fuels in an optical research engine using laser-induced fluorescence. Our test shows that as well as electric driving on renewable electricity, there are other concepts that permit long-distance, low-emission driving. The optical research engine was another test station. Click to enlarge.

Heliostat Consortium announces 7 projects to receive combined $3.5M in funding; DOE launches Heliostat Prize

Green Car Congress

Heliostats are mirrors that track the sun in order to reflect highly concentrated sunlight to a receiver, where it can be stored as heat for long-duration energy storage and converted into electricity. Digital Twin and Industry 4.0

Global Bioenergies to collaborate with Audi on development of drop-in bio-isooctane

Green Car Congress

Global Bioenergies has engineered an initial series of bacterial strains that can produce light olefins via the fermentation of sugars. In other words, can high-octane fuels enable overall energy use and greenhouse gas reductions in the future, or is a better overall outcome achieved through making the best of today’s fuels?

Texas Clean Energy Project signs long-term CO2 offtake agreement with Whiting Petroleum for enhanced oil recovery; 90% CO2 capture from IGCC coal polygen plant

Green Car Congress

Its high carbon-capture rate reduces the total amount of CO 2 emitted to the atmosphere to less than 10% of the emissions for power from a conventional coal plant, and less than 25% of those for power from a highly efficient, natural gas-fired plant, according to Summit. —Donald Hodel, Chairman of Summit Power.

The Complex Calculus of Clean Energy and Zero Emissions

Cars That Think

Among the most articulate and almost certainly the wonkiest is Jesse Jenkins , a professor of engineering at Princeton University, where he heads the ZERO Lab—the Zero-carbon Energy systems Research and Optimization Laboratory, that is. and “Is your electricity bill reasonably affordable?” clean-tech legislation.

A closer look at why heat pumps are dominating EV HVAC systems

Charged EVs

If you want to heat up a space that is cold, there are a number of options, from burning a fuel to directly converting electricity into heat (i.e. cyclopentane), a potent greenhouse gas (e.g. To convert between the two, the ratio is 1 W = 3.412 BTU / hr. CFCs, or chlorofluorocarbons), or toxic (e.g.
