Biogas And Biomethane Could Bolster The Green Circular Economy

Countries around the world are turning to biogas and biomethane to enhance their energy and food security and jump-start their circular economies.

Biogas is produced by breaking down organic waste – agricultural, food, municipal or animal, including manure and sewage – through a process known as anaerobic digestion, while biomethane removes greenhouse gases via carbon capture. Digestate, the other by-product of anaerobic digestion, can also be used as fertiliser.

Ford Says Its New Tennessee Operation Will Be World’s First Carbon-Neutral Auto Plant

Ford Motor Company’s announcement that it will invest $11 billion in the production of electric vehicles will mean 10,800 jobs in Kentucky and Tennessee.

The initiative reflects what clean energy advocates have been saying for years — that electric vehicles can create jobs — but the decision to stop producing products that require fossil fuels was likely not a sudden change of heart for the company.

Biofuels may have fewer effects on the environment than fossil fuels

Production and use of biofuels is considered by the U.S. government to have fewer or lower negative effects on the environment compared to fossil-fuel derived fuels. There are also potential national economic and security benefits when biofuel use reduces the need to import petroleum fuels. Government programs that promote and/or require biofuels use, such as the U.S. Renewable Fuel Standard (RFS) and California's Low Carbon Fuel Standard (LCFS), define the types of biofuels and processes or low-carbon pathways by which biofuels can be produced in order for them to qualify for use under the programs. While biofuels have environmental benefits, their production and use do have effects on the environment.

Science Needs the Right Attitude For Nalinrat Guba, Every Discovery Starts With Curiosity

"Science" was a class you probably took in school, but the subject matter you studied was not the only thing you learned. Your science classes helped you develop a mindset, a way of problem-solving, that you can still tap into today in any line of work.

People with various academic and experiential backgrounds collaborate with the researchers at the National Renewable Energy Laboratory (NREL). They have opportunities to work with people like Nalinrat Guba, whose scientist mindset is complemented by those of an artist, athlete, and caretaker. These perspectives make her a versatile and impactful member of NREL's Computational Science Center, where clients come to achieve their goals leveraging computational science, high-performance computing, applied mathematics, and advanced computer science, visualization, and data.

News Release: Catalytic Process With Lignin Could Enable 100% Sustainable Aviation Fuel

An underutilized natural resource could be just what the airline industry needs to curb carbon emissions.


Researchers at three institutions—the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), the Massachusetts Institute of Technology (MIT), and Washington State University—report success in using lignin as a path toward a drop-in 100% sustainable aviation fuel. Lignin makes up the rigid parts of the cell walls of plants. Other parts of plants are used for biofuels, but lignin has been largely overlooked because of the difficulties in breaking it down chemically and converting it into useful products.

Untold human suffering” is in the near future as U.N. warns climate change is pushing Earth closer to extreme warming

Three new reports from the United Nations paint a grim picture of what’s to come in the near future as the world falls short in mobilizing against climate change. According to the reports, nations are failing to create and act on sufficient plans to reduce warming as global greenhouse gas emissions are on the rise — a combination that is putting the planet on track to hit nearly 3 degrees Celsius of warming within less than 80 years.

DOE Releases Roadmap to Achieve Carbon Neutral Aviation Emissions

WASHINGTON, D.C. — U.S. Secretary of Energy Jennifer M. Granholm today announced the release of the Sustainable Aviation Fuel Grand Challenge Roadmap, a comprehensive plan that outlines a government-wide strategy for scaling up new technologies to produce sustainable aviation fuels (SAFs) across the U.S. airline industry. A collaboration between the U.S. Departments of Energy, Agriculture, Transportation, the Environmental Protection Agency, and Federal Aviation Administration, the roadmap will spur technological innovation to produce SAF, position the country as a global leader in the emerging SAF market, and enable America to meet President Biden’s clean energy goal of a net-zero carbon economy by 2050.
