The Atlantic: Who Killed the Supergrid?

On August 14, 2018, Joshua Novacheck, a 30-year-old research engineer for the U.S. National Renewable Energy Laboratory, was presenting the most important study of his nascent career. He couldn’t have known it yet, but things were about to go very wrong.

At a gathering of experts and policy makers in Lawrence, Kansas, Novacheck was sharing the results of the Interconnections Seam Study, better known as Seams. The Seams study demonstrated that stronger connections between the U.S. power system’s massive eastern and western power grids would accelerate the growth of wind and solar energy—hugely reducing American reliance on coal, the fuel contributing the most to climate change, and saving consumers billions. It was an elegant solution to a complicated problem.

Democrats in Congress have recently cited NREL’s work to argue for billions in grid upgrades and sweeping policy changes. But a study like Seams was politically dangerous territory for a federally funded lab while coal-industry advocates—and climate-change deniers—reign in the White House. The Trump administration has a long history of protecting coal companies, and unfortunately for Novacheck, a representative was sitting in the audience…

This investigative feature, a co-production for The Atlantic and Seattle-based nonprofit journalism studio InvestigateWest, has been over 18 months in the making. I had the story at the outset, but I needed documents obtained via the Freedom of Information Act to back-up — and protect — my sources.

Micro-Satellite Spies on Carbon Polluters

Attention greenhouse gas emitters: There’s a new eye in the sky that will soon be photographing your carbon footprint and selling the images to any and all. It’s a micro-satellite dubbed “Claire” (clear, bright, and clean in French) by its Montreal-based developer, GHGSat. This microwave-oven-sized pollution paparazzo rocketed to a 512-kilometer-high orbit in mid-June care of the Indian Space Agency, with a mission to remotely measure the plumes of carbon dioxide and methane wafting up from myriad sources on Earth’s surface. Claire’s targets include power plants, natural gas fracking fields, rice paddies, and much more—just about any emissions source that someone with a checkbook (corporations, regulators, activists) wants tracked, according to GHGSat president Stéphane Germain.

Understanding the IPCC’s Devotion to Carbon Capture

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.

Can China Turn Carbon Capture into a Water Feature?

In an intriguing footnote to their historic climate deal this month, Chinese President Xi Jinping and U.S. President Barack Obama called for demonstration of a hitherto obscure tweak to carbon capture and storage (CCS) technology — one that could simultaneously store more carbon and reduce water consumption. Such an upgrade to CCS holds obvious attraction for China, which is the world’s top carbon polluter and also faces severe water deficits, especially in the coal-rich north and west. Obama and Xi pledged joint funding for a project that would inject 1 million tons of captured carbon dioxide deep underground, annually, and simultaneously yield approximately 1.4 million cubic meters of water.

NASA Launches its First Carbon-Tracking Satellite

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.

Capturing Carbon is One Thing. Keeping It Down is Another.

The IPCC recently stated that failure to deploy technology to capture carbon emissions from coal would double the cost of stopping climate change. Two coal-fired power plants nearing completion in Saskatchewan and Mississippi will be the first in the world to actually prove the technology, capturing their CO2 emissions and store that bolus of greenhouse gases underground. You can learn how they will do it in my latest for Technology Review. However, one point dropped from that story bears stressing. Part of what makes the extra cost of carbon capture feasible for these plants is that they have buyers for their CO2: oilfield operators who will use the stuff as a solvent to loosen up petroleum stuck in aging oil wells. That means the CO2 may not be permanently trapped underground warns Sarah Forbes, a carbon capture expert at the Washington-based World Resources Institute. In Canada ensuring CO2 stays underground is urgent, according to Robert Watson, CEO of SaskPower, the utility completing the coal-fired power plant in Saskatchewan. Watson told me that the oilfield operator taking his plant’s CO2 must ensure that any CO2 that comes back to the surface with produced oil is recycled back underground: “They’re going to have to assure the government that they can account for all of the CO2 they use all of the time.”

Sniffing Gas: White House Taps ARPA-E to Boost Methane Detection

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.
