Where Does Bioenergy Fit into a Low-Carbon Future?

January 20, 2015 by Energy @ MIT
2

Biofuels like ethanol and other forms of bioenergy are often seen as a key part of a low-carbon future. But large-scale production of these fuels would represent a major shift in how the world makes its energy and uses its land — with implications for global food prices and natural resources like forests.[read more]

As Climate Impacts Accelerate, Speed of Mitigation Becomes Key

December 23, 2014 by Durwood Zaelke

The U.S. risks moving from climate denial to climate despair; that citizens can do little to stop impacts, that government doesn't have the political courage needed to adequately address the problem, and that industry genius will falter and not develop the technologies to solve climate change in time.[read more]

How Much Renewable Natural Gas Can Be Produced?

Renewable Natural Gas Production Levels

Renewable natural gas (RNG) is methane produced from biomass that is cleaned to pipeline quality standards and blended with fossil natural gas. RNG, also known as biomethane, is carbon-neutral and chemically identical to fossil natural gas allowing it to be blended without restriction.[read more]

Analyzing IEA Forecasts

This article takes a look at the accuracy and consistency of International Energy Agency forecasts by comparing a range of historical forecasts with actual data. The largest deviations are observed when looking at oil, coal and renewables other than hydro.[read more]

Is Cellulosic Ethanol All it’s Cracked Up to Be?

December 15, 2014 by Edward Dodge
20

The EPA has long promoted cellulosic ethanol as the future of biofuels, but technical challenges have kept production far below targets. A recent rule change allows renewable natural gas to qualify as cellulosic biofuel even though RNG is not cellulosic, but this helps the EPA to appear to be meeting their goals.[read more]

Energy Access and Clean Fuels

Though awareness of energy access challenges in developing countries grows, most of the attention goes to electricity. The statistics on access to clean cooking and heating fuels are just as, if not more staggering as the electrification challenge. Ensuring access to modern fuels demands as much urgency.[read more]

Catalyzing Green

Yuriy Román leads a research group in MIT’s Department of Chemical Engineering. The core of his research is the catalytic conversion of the inedible parts of plant matter, such as cellulose and lignin, into chemicals useful for making fuels and substances like plastics, lubricants, and pharmaceuticals.[read more]

EPA and the Renewable Fuel Standard

Rumors swirled recently that the EPA would finally announce the 2014 renewable volume obligations – quantity of ethanol and biofuels to be blended into fuel – until the they surprised many by postponing until next year. The renewable fuel standard, as the law is known, has been controversial for years.[read more]

Radio Waves and Energy

I have found over the years that the vast majority of biomass to energy projects aren’t economically viable for one reason or another. I have looked at companies that utilize many different conversion technologies, and most of the time my job consisted of searching for fatal flaws of different approaches.[read more]

Utilizing GIS for Renewable Energy Projects

November 15, 2014 by Dan Liggett

GIS and Renewables

Your renewable energy infrastructure projects are far too expensive to make random decisions on siting. For many reasons – not the least of which are cost, efficiency and productivity – siting should be as exact as the science behind renewable energy itself.[read more]

Ethanol and Fuel Standards

The hand-wringing and soul-searching that has gone on at the United States Environmental Protection Agency regarding a proposed reduction in the amount of ethanol to be blended in the gasoline in 2014 is emblematic of a policy based on optimistic projections divorced from reality.[read more]

Renewaable Fuel Standard Effects

The Renewable Fuel Standard was designed to introduce increasing volumes of biofuels into the US liquid transportation fuel system. The standard has been expanded over time with greater focus given to advanced biofuels like cellulosic ethanol that do not use food crops as a direct feedstock.[read more]
