DOE awards ~$25M to 8 projects for CO2 capture and compression; $15M for novel Direct Fuel Cell system

September 02, 2015

The US Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) has selected eight projects to receive almost $25 million in funding to construct small- and large-scale pilots for reducing the cost of CO2 capture and compression through DOE’s Carbon Capture Program. More than half of the funding ($15 million) will go to FuelCell Energy for a pilot scale project using one of the company’s Direct Fuel Cells for carbon capture and compression.

The DOE’s Carbon Capture Program consists of two core research technology areas, post-combustion capture and pre-combustion capture, and also supports related CO2 compression efforts. Current research and development efforts are advancing technologies that could provide step-change reductions in both cost and energy penalty compared to currently available technologies.

New diamine-appended MOFs can capture CO2 for half or less of the energy cost of current materials

March 12, 2015

UC Berkeley chemists have developed a new material that can efficiently capture CO2 and then release it at lower temperatures than current carbon-capture materials, potentially cutting by half or more the energy currently consumed in the process.

The material, a metal-organic framework (MOF) modified with nitrogen compounds called diamines, can be tuned to remove carbon dioxide from the room-temperature air of a submarine, for example, or the 100-degree (Fahrenheit) flue gases from a power plant. A paper elucidating the mechanism of what the researchers are calling “phase-change” adsorbents is published in the journal Nature.

Polymer microcapsules with liquid carbonate cores and silicone shells offer a new approach to carbon capture

February 09, 2015

A multi-institution team of researchers has developed a novel class of materials that enable a safer, cheaper, and more energy-efficient process for removing greenhouse gas from power plant emissions. The approach, described in a paper in the journal Nature Communications, could be an important advance in carbon capture and sequestration (CCS).

The team, led by scientists from Harvard University and Lawrence Livermore National Laboratory, employed a microfluidic assembly technique to produce microcapsules that contain liquid sorbents encased in highly permeable polymer shells. They have significant performance advantages over the carbon-absorbing materials used in current CCS technology.

US and China jointly announce GHG reduction targets; US to cut net GHG 26-28% by 2025, China to peak CO2 by ~2030

November 12, 2014

The US and China jointly announced greenhouse gas (GHG) reduction targets. US President Barack Obama said the US will cut net greenhouse gas emissions in the US by 26-28% below 2005 levels by 2025. At the same time, President Xi Jinping of China announced targets to peak that country’s CO2 emissions around 2030, with the intention to try to peak early, and to increase the non-fossil fuel share of all energy to around 20% by 2030. Together, the US and China account for more than one third of global greenhouse gas emissions.

The new US goal will double the pace of GHG reduction from 1.2% per year on average during the 2005-2020 period to 2.3-2.8% per year on average between 2020 and 2025. The Administration said that the ambitious target is grounded in analysis of cost-effective carbon pollution reductions achievable under existing law and will keep the United States on a trajectory to achieve deep economy-wide reductions on the order of 80% by 2050.
