USDA provides $91M loan guarantee to Cool Planet for biogasoline blendstock plant; biomass pyrolysis and catalytic conversion

Green Car Congress

Gas chromatography comparison of Conoco fuel and a Conoco-CoolPlanet blend. Cool Planet has devised a biomass-to-liquids thermochemical conversion process that simultaneously produces liquid fuels and sequesterable biochar useful as a soil amendment. The output of these processing stations is connected to an array of catalysts.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. It took us a long time to get the data needed to let us connect to the grid.

Geely invests in Carbon Recycling Intl.; vehicles fueled by methanol from CO2, water and renewable energy

Green Car Congress

Geely’s CRI investment and work with renewable methanol is similar to the approach Audi is taking with its own e-fuels projects—producing very low carbon liquid or gaseous fuels using only renewable energy, water and CO 2. Their results showed that in comparison with gasoline mode, CO emitted in methanol mode decreased 11.2%.

Mercedes-Benz adds LPG dual fuel Sprinter variant to line-up

Green Car Congress

The particulate emissions of LGT engines are virtually zero, while emissions of nitrogen oxides, hydrocarbons and carbon monoxide, as well as sulphur dioxide, are significantly reduced in comparison with diesel engines. The gas connection is located above the gasoline filler neck, behind the fuel filler flap.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

Business-as-usual’ projections of future conversion rates, based on historical rates over the past two decades, indicate that 6–9 Mha of peatland in insular Southeast Asia may be converted to plantations by the year 2020, unless land use planning policies or markets for products change. —Miettinen et al.

New Review Concludes Very Low EROI of Oil Shale Combined with High Carbon Intensity Likely Makes it an Unsuitable Alternative to Conventional Crude Oil

Green Car Congress

A comparison of estimates of the energy return on investment (EROI) at the wellhead for conventional crude oil, or for crude product prior to refining for oil shale. While one could argue that the char and gas produced and consumed within the shale conversion process has zero opportunity cost—i.e., Source: Cleveland and O’Connor.

The EV Transition Explained: Can the Grid Cope?

Cars That Think

In comparison, the state’s goal is to achieve this amount by 2050. The city has provided incentives for the purchase of both EVs and charging ports, the installation of heat-pump water heaters , and the installation of solar and battery-storage systems. Or we can’t even have one EV charger go in.” Peak loading is the primary concern.
