I’ve delivered several dispatches on carbon capture and storage (CCS) recently, including a pictorial ‘how-it-works’ feature on the world’s first commercial CCS power for Technology Review. Two aspects of CCS technology and its potential applications bear further elaboration than was possible in that short text. Most critical is a longer-term view on how capturing carbon dioxide pollution from power plants (and other industrial CO2 sources) can serve to reduce atmospheric carbon dioxide concentrations. The Intergovernmental Panel on Climate Change is looking for CCS to do much more than just zero out emission from fossil fuel-fired power plants.

Context is everything in understanding the U.S.-China climate deal struck in Beijing by U.S. President Barack Obama and Chinese President Xi Jinping last week. The deal’s ambitions may fall short of what climate scientists called for in the latest entreaty from the Intergovernmental Panel on Climate Change, but its realpolitik is important.
Obama and Xi’s accord sets a new target for reductions in U.S. greenhouse gas emissions: 26-28 percent below 2005 levels by 2025. And for the first time sets a deadline for China’s rising GHGs to peak: 2030. This is potentially strong medicine for cooperation, when seen in the context of recent disappointments for global climate policy.

European leaders wrapped up a two-day climate summit in Brussels last week with a deal to cut the European Union’s total greenhouse gas emissions to 40 percent below 1990 levels. This would continue a downward trend – the EU is already on track to meet a 20 percent reduction from 1990 levels by 2020 – but the agreement is weak relative to Europe’s prior ambitions to confront climate change.
Investors in green tech pushed aggressively for the deal, seeking a longterm signal that the European market will continue to reward advances in energy efficiency and low-carbon energy production. The deal is also a shot in the arm for the Paris global climate talks, scheduled for December 2015, which will seek to achieve the decisive binding global targets for greenhouse gas reductions that failed to emerge from the 2009 Cophenhagen climate talks.
What the deal lacks is specificity and ambition regarding the mechanisms by which European countries are to achieve the carbon reduction. “Key aspects of the deal that will form a bargaining position for global climate talks in Paris next year were left vague or voluntary,” reported The Guardian.

It’s been a rough birthing process for NASA’s Orbiting Carbon Observatory (OCO) satellite program, which promises global tracking of carbon dioxide entering and leaving the atmosphere at ground level. Five years ago the first OCO fell into the Antarctic Ocean and sank, trapped inside the nose cone of a Taurus XL launch vehicle that failed to separate during launch. The angst deepened yesterday when NASA’s Jet Propulsion Laboratory (JPL) scrubbed a first attempt to launch a twin of the lost $280-million satellite, OCO-2, after sensors spotted trouble with the launch pad’s water-flood vibration-damping system less than a minute before ignition.
This month’s issue of IEEE Spectrum spotlights methane emissions overlooked by the U.S. EPA’s official inventory, and the satellite-based detector launching next year to map this “missing methane.” Last week the White House acknowledged EPA’s missing methane problem, and laid out a strategy to combat it. While promising to improve EPA’s inventory, including more use of top-down methane measurement, the White House also promised federal investment in ground-based methane sensing to plug leaky natural gas systems thought to be the source of much of the missing methane. Action can’t come soon enough according to the Intergovernmental Panel on Climate Change (IPCC), which on Monday unveiled its latest climate assessment. The IPCC said “widespread and consequential” impacts are already visible and world leaders have only a few years to change course to avoid catastrophic warning. Methane is a major contributor according to the scientific body, which deems methane to be up to 44 percent more potent as a warming agent than previously recognized.

The Arctic is melting faster than predicted. Is now the time to shut down the low-carbon nuclear power plants in France — the 20th Century’s staunchest proponent of nuclear energy? Is natural gas produced via hydraulic fracturing or ‘fracking’ a gift that is buying time for a transition to renewable energy or a curse that reinforces fossil fuel dependence? Will carbon belching heavyweights such as the U.S. and China ever get serious about cleaning up their energy systems?
Such questions are top order in France, whose President kicked off a Grand Débat on energy this month Continue reading “The Debate: Fracking and the Future of Energy”
Natural gas has no odor, but you can smell a leak thanks to the addition of an odorific mercaptam compound. Do carbon dioxide and other similarly odorless greenhouse gases (GHGs) require some analogous device to make their presence known and thus prompt evasive action? Yes, and for these ubiquitous gases, it will be a visual cue indicating the source and quantity of GHGs Continue reading “Rendering Greenhouse Gases Visible”
