China’s Grid Architect Proposes a “Made in China” Upgrade to North America’s Power System

Transmission lines in the United States and Canada require approval from every state and province traversed, and that political fragmentation hinders deployment of long power links of the type connecting vast swaths of territory in regions such as China, India, and Brazil. As a result, few studies detail how technologies that efficiently move power over thousands of kilometers, such as ultrahigh-voltage direct current (UHV DC) systems, might perform in North America. Earlier this week, the Beijing-based Global Energy Interconnection Development and Cooperation Organization (GEIDCO) stepped in to fill that gap, outlining an ambitious upgrade for North America’s grids.

GEIDCO’s plan promises to greatly shrink North America’s carbon footprint, but its boldest prescriptions represent technical and economic optimizations that run counter to political interests and recent trends. “Thinking out of the box is how you solve complicated, difficult problems,” said former Southern California Edison CEO Ted Craver in response to the plan. But GEIDCO’s approach, he said, raises concerns about energy sovereignty that could prove difficult to settle. As Craver put it: “There’s theory and then there’s practice.”

The proposed North American transmission scheme was unveiled on Tuesday at an international transmission forum in Vancouver, Canada, by Liu Zhenya, the former State Grid Corp. of China chairman who launched GEIDCO in 2016. While at State Grid, Liu championed the development of the world’s first 800- and 1,100-kilovolt UHV DC lines and the first 1,000-kV, UHV AC transmission. State Grid has deployed them to create a brawny hybrid AC-DC electricity system that taps far-flung energy resources to power China’s densely-populated and industrialized seaboard.

Through GEIDCO, Liu is proselytizing for UHV deployment worldwide. At the Vancouver meeting, Liu warned of “unimaginable damage to mankind” if greenhouse gas emissions continued at their current pace. He argued that beefy grids moving power across and between continents are a prerequisite for accessing and sharing the world’s best wind, solar, and hydropower resources, and thus dialing-down fossil fuel consumption.

LA Times: On fire, soot, death and disinformation

An LA Times op-ed by statistician David Fairley and myself …

For nearly two weeks last November, smoke from the Camp fire drained 150 miles down the Central Valley and out toward the sea, engulfing Sacramento and the whole Bay Area. San Francisco looked — and breathed — like New Delhi, the world’s most polluted city. Miles away in the mountain town of Paradise, the fast-moving conflagration killed 85 people — making the Camp fire the deadliest wildfire in state history. But pollution research suggests that once heart attacks and respiratory-related deaths are factored in, its soot was even more deadly than its flames. Based on earlier pollution studies, we project that soot from the Camp fire caused about 100 premature deaths just in the San Francisco Bay Area and hundreds more hospitalizations and emergency room visits than normal.

Swarm Electrification in Bangladesh

Bangladesh hosts the world’s largest collection of off-grid solar energy systems. Rooftop panels and batteries electrify over 4 million households and businesses there. Dhaka-based startup ME SOLshare believes it has the technology to link these systems and foster a solar energy-sharing economy. If the company succeeds, home systems will morph into village minigrids, offering wider access to more power at lower cost. Continue reading “Swarm Electrification in Bangladesh”

Scientists Get Political on Climate

It’s moving day at the Legislative Assembly of British Columbia on a sunny summer morning in Victoria, Canada, and climate scientist-turned politician Andrew Weaver is battling to retain an expansive leather sofa for his new basement office. Just a few weeks earlier, in May 2017, thousands of people in and around Victoria cast their votes for the British Columbia Green Party, which Weaver leads, growing the caucus from his one lonely seat to three. The wide sofa, he explains, will be crucial during long nights of debate and voting. “This is the one you can sleep on. And we need that.” Three seats in an 87-seat legislature might sound modest, but it’s enough to make Weaver — a professor at the University of Victoria — into a political kingmaker. The incumbent Liberal Party and the opposition New Democratic Party each garnered fewer than half of the seats, giving Weaver’s Green Party the balance of power. Weaver exercised his new-found influence in the weeks after the election to remove Christy Clark, the Liberal premier of British Columbia, who had championed fossil fuels, and to install a new government under climate-friendly terms. Now US researchers are daring to dream that they too can follow in Weaver’s footsteps, and tilt the political balance. … READ ON AT NATURE.COM

Are UN Climate Assessments Obsolete?

 

The sweeping multi-year assessments produced by the Intergovernmental Panel on Climate Change set the gold standard for global scientific consensus on how humanity is altering Earth’s climate, and how to anticipate and minimize those changes. Some top climate scientists, however, are reviving a harsh critique of the IPCC’s assessment process, saying that it takes too long and that the delay could actually be creating an excuse for political inaction. The production cycle for what will become IPCC Sixth Assessment Report—began in 2015 and will not conclude until 2022. That seven-year schedule is simply unacceptable for a document that is “relied on by countless decision makers around the world every day,” said Katharine Hayhoe, an atmospheric scientist and co-director of the Climate Science Center at Texas Tech.

Commentary: Photo Ops with Miners No Substitute for Climate Policy

President Donald Trump surrounded himself with coal miners at the EPA yesterday as he signed an executive order calling for a clean sweep of federal policies hindering development of fossil fuel production in the United States. The order instructs EPA to kill Obama’s Clean Power Plan and thus, according to Trump’s rhetoric, revive coal-fired power generation and the miners who fuel it. The electric power sector, however, responded with polite dismissal. What separates President Trump and some of his top officials from power engineers and utilities? The latter operate in a world governed by science and other measurable forces. Unlike President Trump, scientists, engineers, and executives suffer reputational and financial losses when they invent new forms of logic that are unsupported by evidence. And a world of fallacies underlies the President and his administration’s rejection of climate action. Continue reading “Commentary: Photo Ops with Miners No Substitute for Climate Policy”

Trump Budget Dumps Climate Science, Innovation

Al Gore didn’t really claim to invent the Internet in 1999, but he did champion a NASA mission that installed a deep space webcam pointed at Earth in 2015. And yesterday President Trump put a bullseye on that mission. Trump’s 2018 budget blueprint asks Congress to defund the Earth-facing instruments on the Deep Space Climate Observatory (DSCOVR). Selectively deep-sixing well-functioning instruments on a satellite 1.5 million kilometers from Earth is one of the stranger entries in President Trump’s first pass at a budget request. But it fits a pattern: Throughout the document programs aimed at comprehending or addressing climate change take deep cuts, even where there is no obvious fiscal justification.
