PNNL study finds algal oil could replace 17% of US petroleum oil imports

Green Car Congress

A new Pacific Northwest National Laboratory (PNNL) study shows finds that oil from algae grown in outdoor raceway ponds located in the Gulf Coast, the Southeastern Seaboard and the Great Lakes could replace 17% of the United States’ imported oil for transportation. The paper is published in the journal Water Resources Research.

Argonne analysis shows greenhouse gas emissions similar for shale, conventional oil

Green Car Congress

Shale oil production generates greenhouse gas emissions at levels similar to conventional crude oil production, according to a pair of new studies released by the US Department of Energy’s Argonne National Laboratory. These are shale formations with low permeability and must be hydraulically fractured to produce oil and gas.

Increase in US rig count will not cap oil prices

Green Car Congress

The impact of rising oil prices on North American light tight oil (LTO) production is said to be a “Catch 22”, the title of Joseph Heller’s popular 1961 novel set in WWII. Too many analysts continue to believe drilling and service has the same problem with rising oil prices. by David Yager for Oilprice.com.

Green Deals: Greenworks 14-inch Electric Dethatcher is a must for older yards at $101, more

Electrek

For comparison, it goes for $130 direct right now and today’s deal is the best available. Dethatching needs to take place when that layer gets too thick and starts to block water, sun, and other things from reaching the soil. This dethatcher is electric, meaning no gas or oil is required for it to function.

Tunable high-yield catalytic approach converts pyrolysis oil to bio-hydrocarbon chemical feedstocks including fuel additives

Green Car Congress

Pyrolysis bio-oils are produced by the thermal decomposition of biomass by heating in the absence of oxygen at more than 500 °C; fast pyrolysis of biomass is much less expensive than biomass conversion technologies based on gasification or fermentation processes. Solid arrows: Pyrolysis oil is directly passed over the zeolite catalyst.
