Big Concentrating Solar Tower Project in Nevada Gets DOE Loan Guarantee

This post reports on the newly announced loan guarantees for the concentrated solar power (CSP) Crescent Dunes Solar Energy Project that is to be built in Nevada. This kind of solar power, because it is paired with a molten salt thermal energy storage capacity has the ability to be a load following generation source that is somewhat insulated from intermittency issues as well. For large concentrated solar thermal energy this decoupling of the energy collection from electricity generation makes a lot of sense, because the molten salt is already being used as the working fluid that captures the sun’s heat.

Can We Trust Climate Models? Increasingly, The Answer is ‘Yes’

Can We Trust Climate Models? Increasingly, The Answer is ‘Yes’

Forecasting what the Earth’s climate might look like a century from now has long presented a huge challenge to climate scientists. But better understanding of the climate system, improved observations of the current climate, and rapidly improving computing power are slowly leading to more reliable methods.

Is Carbon Capture Leaking Out Onto Green Pastures?

Is Carbon Capture Leaking Out Onto Green Pastures?

In a troubling development for proponents of geologic carbon sequestration a Saskatchewan farmer has just made public an independent study that links high levels of CO2 found in their farm’s soil to the thousands of tons of CO2 that is currently being pumped into deep oil bearing deposits under their land by Canadian Energy giant Cenovus.

Embodied Energy, a Measure of Sustainability

Embodied Energy, a Measure of Sustainability

What is the meaning and importance of embodied energy as a measure of sustainability and why we need to develop widely accepted standards for embodied energy? This article explores this somewhat arcane concept that seeks to measure how much energy is “embodied” in a product or service; in other words how much energy is used throughout the entire life cycle of the thing being measured including the energy required by decommissioning, disassembly and deconstruction.

Algae Biofuels – Not Sustainable (Another Response to “Could Algae be the New Corn?” by Julia Verdi)

Algae Biofuels – Not Sustainable (Another Response to “Could Algae be the New Corn?” by Julia Verdi)

Last week, Frank Ciampa, posted Algal Biodiesel: Pros and Cons, his response to Could Algae be the New Corn?, written by Julia Verdi. This week, Eamon Keane, responds to Julia’s post, explaining why he does not feel that algae biofuels is a good alternative to oil.

Could Algae be the New Corn?

Could Algae be the New Corn?

Studies show that corn based ethanol may nearly double greenhouse gas emissions instead of reducing them. Does Algae pose the same risks as corn? Are biofuels the wrong way to go when it comes to identifying fuel sources?

The Economic Case for Slashing Carbon Emissions

The Economic Case for Slashing Carbon Emissions

Amid a growing call for reducing atmospheric concentrations of CO2 to 350 parts per million, a group of economists maintains that striving to meet that target is a smart investment — and the best insurance policy humanity could buy.

CO2 Capture and Storage Gains a Growing Foothold

CO2 Capture and Storage Gains a Growing Foothold

The drive to extract and store CO2 from coal-fired power plants is gaining momentum, with the Obama administration backing the technology and the world’s first capture and sequestration project now operating in the U.S. Two questions loom: Will carbon capture and storage be affordable? And will it be safe? by David Biello, Editor of Scientific […]
