How to rescue biofuels from a sustainable dead end

In 2011, I scrutinized a gathering wave of biofuels for Nature, and that deep dive on making fuels from woody rather than sugary plant material remains one of my most-cited works. Perhaps because we nailed what emerged as the technology’s as-yet-insurmountable hurdle: making the conversion processes work consistently at industrial scale.

A little over a decade later Nature take another look at the sustainability of biofuels. The picture isn’t pretty, thanks in part to the failure of those cellulosic fuels.

Biofuels continue to grow in ways that overlap with food crops, contributing to agricultural expansion at the expense of carbon-storing forests and grasslands. And poorly conceived and regulated mechanisms for tracking and rewarding carbon storage by farms threaten to exacerbate the trouble.

It will take a “ground-up revamp” for agriculture to get biofuels right, both for the environment and for farm communities. As we conclude, it looks like déja vu all over again: “If the sustainability of biofuels depends on such fundamental changes, one has to wonder whether another next-generation biofuels failure isn’t the more likely outcome.”

Piercing the fog of war at Ukraine’s embattled Zaporizhzhia Nuclear Plant

After plumbing Ukraine’s lightning fast leap to unplug from Russia’s power grid and a pair of exposés exposing Russian moles within its nuclear energy utility, my latest reporting on the #EnergyFront refocused coverage of the warfare threatening Europe’s largest nuclear power plant. While domestic and international reporting focused on the terrifying explosions rocking Zaporizhzhia — a perilous game of nuclear roulette — my stories spotlighted efforts by Ukrainian nuclear experts to cancel the game, and thus slash the risk of devastating reactor meltdowns.

Few stories questioned why Zaporizhzhia was still producing power in the middle of a war zone. U.S. reactors proactively shut down when, for example, a hurricane is barreling in. Why was Ukraine’s nuclear utility and energy ministry and nuclear regulator ordering Zaporizhzhia’s operators to do otherwise, and why was its nuclear regulator allowing it? The answer: Ukraine wanted to maximize its power supply to bolster electricity exports to Europe in a bid for political support and badly-needed revenue.

But nuclear experts I spoke to, such as former Chernobyl chief engineer and IAEA board member Nikolai Steinberg, called maintaining nuclear chain reactions at Zaporizhzhia “a crime.” Shutting down, Steinberg and others argued, would cool Zaporizhzhia’s reactors, thus slashing the risk of an accident akin to (or potentially worse than) Japan’s Fukushima disaster.

My first story laid out the experts’ case for a proactive shutdown. For example, I cited an unpublished assessment by Ukraine’s state nuclear-safety center reviewing the risk of a station-wide blackout that would zap the plant’s ability to cool its reactors and pools of spent nuclear fuel (as occurred at Fukushima in 2011). Moving Zaporizhzhia’s reactors to a ‘cold stop’, they found, would reduce accident risk by extending the time between station blackout and reactor core damage from 3 hours to 27 hours, buying crucial time for operators to find workarounds and restart cooling.

Shutting down proactively would also cease the production of short-lived fission products, reducing the harm caused by any reactor breach.

I followed up one week later after shelling (most likely by the Russian forces occupying the plant) forced the entire plant off the grid for the first time since it began operating in 1985, and temporarily shut down two reactors. My story explained how:

  • Repeated damage to Zaporizhzhia’s transmission lines — the electrical umbilical cords linking it to Ukraine’s grid — caused the plant’s reactors to blink on and off the grid.
  • The near misses bolstered calls for an orderly shutdown, even if diesel generators and other emergency systems had averted radiological accidents; and
  • Ukrainian officials continued to restart reactors and power generation rather than heed the warnings.

My story also noted, however, that nuclear experts had scored one win. Ukraine’s nuclear regulator took a symbolic baby step by ordering two reactor units already in cold shutdown to remain offline.

A few days later after that story the White House called for a “controlled shutdown” at Zaporizhzhia. Ukraine’s nuclear utility Energoatom acceded to the growing chorus on September 11.

And, for the win, it’s… Who Killed The Supergrid !

In August 2020 over 18 months of reporting paid off with my investigative feature Who Killed The Supergrid – an InvestigateWest production co-published with The Atlantic. Today that work and its immediate impact was recognized with an investigative journalism award from Covering Climate Now. That consortium, created in 2019 by the Columbia Journalism Review, The Nation, The Guardian and WNYC, has since grown into a who’s who of international media, and I’m honoured that they picked my work from more than 600 nominated entries.

In the words of the judges:

This meticulous story revealed the Trump administration’s deliberate effort to bury a federally funded study that provided evidence that a connected super grid would accelerate the growth of wind and solar energy. The story made the abstraction of the nation’s power grid interesting, and Fairley’s explosive disclosures also led to regulatory change.

Individual panelists added commentary during the video awards celebration (see below). Giles Trendle, Managing editor for Al Jazeera English, called my story, “another great example of holding power to account.”

I have thanked many of the talented people who contributed to this success in the Twitter thread at right. But a few bear repeating:

My friend, longtime SEJ colleague, and editor Robert McClure, co-founder of InvestigateWest, jumped at the opportunity to take on my project and helped me take it all the way. I’m grateful that ‘just good enough’ isn’t in Robert’s DNA.

The team at The Atlantic, including Ellen Cushing and Faith Hill, further improved the prose and managed a very thorough fact check.

And the Fund for Investigative Journalism provided financial support plus access to a valuable pre-publication legal review by the Reporters Committee for Freedom of the Press.

FYI the awards video hosted by ‘America’s weatherman’ Al Roker and NBC Live NOW anchor Savannah Sellers showcases all of the 2021 award program’s winning entries from around the world. It’s inspiring and informative. Definitely worth watching, and sharing…

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. 

Scientific American: Solar And Wind Power Could Ignite A Hydrogen Energy Comeback

Hydrogen is flowing in pipes under the streets in Cappelle-la-Grande, helping to energize 100 homes in this northern France village. On a short side road adjacent to the town center, a new electrolyzer machine inside a small metal shed zaps water with electricity from wind and solar farms to create “renewable” hydrogen that is fed into the natural gas stream already flowing in the pipes. By displacing some of that fossil fuel, the hydrogen trims carbon emissions from the community’s furnaces, hot-water heaters and stove tops by up to 7 percent.

So begins my February 2020 feature article for Scientific American which explains why hydrogen energy — presumed dead after a round of hype and disillusion two decades ago — is roaring back. Renewable hydrogen is central to the European Commission’s vision for achieving net-zero carbon emissions by 2050, for example, and a growing focus for the continent’s industrial giants. As of next year, all new turbines for power plants made in the European Union are supposed to ship ready to burn a hydrogen–natural gas blend, and the E.U.’s manufacturers claim the turbines will be certified for 100 percent hydrogen by 2030.

This time around it is the push to decarbonize the electric grid and heavy industry—rather than hope for fuel cell vehicles—that is driving interest in hydrogen. “Everyone in the energy-modeling community is thinking very seriously about deep decarbonization,” says Tom Brown, who leads an energy-system modeling group at Germany’s Karlsruhe Institute of Technology. Cities, states and nations are charting paths to reach nearly net-zero carbon emissions by 2050 or sooner, in large part by adopting low-carbon wind and solar electricity. Integrated energy models show that they’ll have a hard time keeping the lights on during periods of low wind and sunlight without hydrogen, and that hydrogen will pay for itself long before it solves that problem.

The Hot Mess of Hawaii’s Renewable Power Push

My first contribution to award-winning Hakai Magazine, which covers coastal science, ecology and communities

Moloka‘i is a bastion of sanity and understatement at the center of the Hawaiian archipelago. Just 40 kilometers of open water away from O‘ahu, the island is a far cry from Honolulu’s hectic tiki bars and tourists, universities, cargo yards, and warships. On Moloka‘i, agriculture and subsistence hunting and fishing still sustain many of the 7,500 or so residents, and visitors are few. Those tourists who do make the hop over rank mailing a coconut home as their top experience.

On the surface, nothing about this bucolic place suggests it as the central hub around which a cleaner, high-tech electrical future might be built. Yet the island could serve as a model for Hawai‘i as the state navigates transitioning its entire power supply to renewable sources.

Honolulu-based Hawaiian Electric, the investor-owned utility that controls Moloka‘i’s grid, must meet a mandate from the state legislature to convert the five island grids it operates to 100 percent renewable energy by 2045. No utility on Earth knows for sure how to accomplish that yet. Pushing Moloka‘i there first and fast, Hawaiian Electric decided, would provide insight and inspiration.

Hawaiian Electric’s idea was to get Moloka’i off diesel generation by 2020. Alas, it is little closer to shutting down the diesels three years later. Can a small Hawaiian island and its utility get along well enough to teach the rest of the world how to get off fossil-fueled electricity?

SPECTRUM: China Stumbles on Path to Solar Thermal Supremacy

In the final days of 2018 a 100-megawatt solar thermal generating station capable of running around-the-clock, 365-days-a-year connected to the Northwest China regional power grid. It was a race against time to commission the plant in temperatures as low as -20 celsius—and one that plant designer and builder Beijing Shouhang Resources Saving Co could not afford to lose.

“We must finish on time. Otherwise we may face a heavy financial problem,” says Chen Han, Shouhang’s director for international markets.

Shouhang was racing to beat the Chinese government’s December 31, 2018 deadline to secure a guaranteed price for the plant’s power. The deadline was part of an aggressive demonstration program launched in September 2016 to slash the cost of solar thermal power and catapult Chinese firms to the head of the global pack—much as China did with solar photovoltaics.

Alas, a little more than two years later, China has stumbled on the path to solar thermal supremacy. While Shouhang’s and two more of the program’s 20 approved projects met the deadline, four others were cancelled last year and the remaining 13 projects are in limbo.
