NREL, MIT, WSU team develops process to convert lignin to aromatic blendstock for 100% sustainable aviation fuel

Green Car Congress

By using lignin, an abundant, renewable biopolymer that has traditionally been underutilized due to its chemical recalcitrance, an aromatic SAF blendstock could be generated. As the largest source of renewable aromatics in nature, lignin could hold the answer to achieving a complete bio-based jet fuel. —Stone et al.

Obama and Trudeau put majority of US and Canadian Arctic water off-limits to offshore oil and gas leasing

Green Car Congress

US President Obama and Canadian Prime Minister Trudeau jointly announced sweeping restrictions to offshore oil and gas leasing in the US and Canadian Arctic waters. Obama designated the vast majority of US waters in the Chukchi and Beaufort Seas as indefinitely off limits to offshore oil and gas leasing. It’s uncharted waters.”.

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.

IRENA report finds renewable power costs at parity or below fossil fuels in many parts of world

Green Car Congress

The cost of generating power from renewable energy sources has reached parity or dropped below the cost of fossil fuels for many technologies in many parts of the world, according to a new report released by the International Renewable Energy Agency (IRENA). Size of the diameter of the circle represents the size of the project.
