High-speed trains may be the latest victim of the Biden administration’s “Buy America” policy, advocates fear.

President Joe Biden wants all materials used in federal infrastructure projects to be made in the U.S., and his $369 billion climate law ties generous tax credits to domestic sourcing requirements for clean energy technologies.

That has contributed to barriers for widespread electric vehicle adoption, tensions with foreign trade partners and, now, the possible squashing of U.S. high-speed rail hopes, writes Minho Kim.

That’s because only a few places in the world build trains capable of traveling 200 mph, said Andy Kunz, president of the advocacy group U.S. High Speed Rail Association. The United States also lacks the facilities and engineering know-how to design, build and maintain the tracks, signals and safety systems needed for such high-speed trains, analysts told Minho.

That could complicate the administration’s goal of reaching net-zero carbon emissions by midcentury.

Biden vowed last year to fund high-speed rail as one of 37 “game changing” technologies to fight climate change. But he also strengthened his administration’s Buy America requirements five days after taking office, creating a new White House office in charge of vetting waiver requests, Minho notes. That will make it harder for rail projects to get exceptions allowing them to use foreign parts, infrastructure specialists predicted.

Transportation is the nation’s largest source of greenhouse gases. Bullet trains produce 14 to 16 times less planet-warming pollution per passenger compared with cars and airplanes.

Zooming out: Biden’s Buy America policy is intended to position the U.S. as a leader in the clean energy transition while creating thousands of domestic jobs. But the measure also poses obstacles to accomplishing those goals fast enough to blunt catastrophic climate change.

For the first time in five years, clean energy installations in the U.S. fell last year, according to a new industry report that overwhelmingly blamed delayed solar capacity on sourcing issues caused by trade restrictions, writes Lamar Johnson.

The U.S. is also trying to create a domestic supply chain for the minerals needed to build EVs, a supply now dominated by China. In 2021, the U.S. imported more than 25 percent of its lithium, 48 percent of its nickel, 76 percent of its cobalt, and all its graphite and manganese. Lessening reliance on those imports will make it harder to spur widespread adoption of EVs.

Today in POLITICO Energy’s podcast: Annie Snider breaks down the details of the tentative deal California, Arizona and Nevada struck to significantly reduce their water use from the drought-stricken Colorado River over the next three years.

In the latest example of how the rivalry between Washington and Beijing is complicating Biden’s climate agenda, the Energy Department has scrapped a proposed $200 million grant to a Texas-based battery company whose connections to China had drawn criticism from lawmakers, write James Bikales and Kelsey Tamborrino.

DOE had tentatively approved the grant seven months ago to Microvast Holdings, a lithium-ion battery company that is planning a manufacturing facility in Tennessee.

Agency spokesperson Charisma Troiano confirmed DOE canceled the award, but declined to say why, write Brian Dabbs and Nico Portuondo.

Solar shake-up
An Italian company announced plans to build a $1 billion solar factory in Oklahoma on Monday, a potentially momentous advance for an industry that is facing uncertain growth and threats to its federal incentives in Congress, writes David Iaconangelo.

The factory could become one of the country’s first to produce crystalline silicon solar cells — a key component in most panels, but one that has not been made at commercial scale in the United States for several years. Most components for solar panels are now imported.

German spats
Germany’s three-party ruling coalition descended into public infighting Tuesday as the Greens’ Vice Chancellor Robert Habeck accused the liberal Free Democrats’ Finance Minister Christian Lindner of breaking promises by delaying a controversial clean energy law, write Hans von der Burchard and Gabriel Rinaldi.

The spat highlights growing tensions in a government whose parties hold diverging opinions over how Germany should implement the European Union’s plans to slash carbon emissions by 55 percent by 2030 and become climate-neutral by 2050.

Boots on the ground: As the federal government struggles to support disaster recovery in the wake of climate-fuel events, extremist groups are stepping in to fill the void.

Twenty oil and gas producers were responsible for half of the industry’s methane emissions in the United States in 2021.

More than 130 lawmakers from the EU and the United States are calling for the removal of oil executive Sultan Al Jaber as president of this year’s COP28 climate talks.

A new study found that climate lawsuits are affecting oil companies’ value — even in the initial stages of litigation.
