Can the world’s most polluting heavy industries decarbonize?

Can the world’s most polluting heavy industries decarbonize?

Fred Pearce writes: We know how to decarbonize energy production with renewable fuels and land transportation with electric vehicles. Blueprints for greening shipping and aircraft are being drawn up. But what about the big industrial processes? They look set to become decarbonization holdouts — the last and hardest CO2 emissions that we must eliminate if we are to achieve net-zero emissions by mid-century. In particular, how are we to green the three biggest globally-vital heavy industries: steel, cement, and ammonia,…

Can nuclear fusion put the brakes on climate change?

Can nuclear fusion put the brakes on climate change?

Rivka Galchen writes: Let’s say that you’ve devoted your entire adult life to developing a carbon-free way to power a household for a year on the fuel of a single glass of water, and that you’ve had moments, even years, when you were pretty sure you would succeed. Let’s say also that you’re not crazy. This is a reasonable description of many of the physicists working in the field of nuclear fusion. In order to reach this goal, they had…

Clean hydrogen could replace fossil fuels for almost everything. But should it?

Clean hydrogen could replace fossil fuels for almost everything. But should it?

Grist reports: As countries around the world firm up their commitments to cut carbon emissions, many are turning to an emerging solution with an uncertain future: hydrogen gas. This lesser-known fuel has been called the “Swiss Army knife” of climate solutions. It has the potential to replace fossil fuels in industrial processes, transportation, buildings, and power plants, and does not emit any greenhouse gases when it’s burned. But this idea of an emissions-free hydrogen-fueled world is a long way off….

We’re finally catching a break in the climate fight

We’re finally catching a break in the climate fight

Bill McKibben writes: So far in the global warming era, we’ve caught precious few breaks. Certainly not from physics: the temperature has increased at the alarming pace that scientists predicted thirty years ago, and the effects of that warming have increased even faster than expected. (“Faster Than Expected” is probably the right title for a history of climate change so far; if you’re a connoisseur of disaster, there is already a blog by that name). The Arctic is melting decades…

From 4% to 45%: Energy Department lays out ambitious blueprint for solar power

From 4% to 45%: Energy Department lays out ambitious blueprint for solar power

The New York Times reports: The Biden administration on Wednesday released a blueprint showing how the nation could move toward producing almost half of its electricity from the sun by 2050 — a potentially big step toward fighting climate change but one that would require vast upgrades to the electric grid. There is little historical precedent for expanding solar energy, which contributed less than 4 percent of the country’s electricity last year, as quickly as the Energy Department outlined in…

It’s not a competition, but renewables are beating nuclear anyway

It’s not a competition, but renewables are beating nuclear anyway

Nathaniel Bullard writes: Energy giant BP Plc has been publishing its annual review of global energy statistics for seven decades. (I’ve been reading it — and digesting its data — for about a fifth of that time.) The latest edition published in July is, understandably, quite focused on the largest year-on-year decline in primary energy consumption since 1945. But there’s another finding worth noting: 2020 was the first year in which renewable power generation (excluding hydro) surpassed nuclear power generation….

Fossil fuel companies are quietly scoring big money for their preferred climate solution: carbon capture and storage

Fossil fuel companies are quietly scoring big money for their preferred climate solution: carbon capture and storage

Inside Climate News reports: Over the last year, energy companies, electrical utilities and other industrial sectors have been quietly pushing through a suite of policies to support a technology that stands to yield tens of billions of dollars for corporate polluters, but may do little to reduce greenhouse gas emissions. These policies have fast-tracked environmental reviews and allocated billions in federal funding for research and development of carbon capture and storage, or CCS, technologies that pull carbon dioxide out of…

Startup claims breakthrough in long-duration batteries

Startup claims breakthrough in long-duration batteries

The Wall Street Journal reports: A four-year-old startup says it has built an inexpensive battery that can discharge power for days using one of the most common elements on Earth: iron. Form Energy Inc.’s batteries are far too heavy for electric cars. But it says they will be capable of solving one of the most elusive problems facing renewable energy: cheaply storing large amounts of electricity to power grids when the sun isn’t shining and wind isn’t blowing. The work…

How marginalized communities in the South are paying the price for ‘green energy’ in Europe

How marginalized communities in the South are paying the price for ‘green energy’ in Europe

CNN reports: Andrea Macklin never turns off his TV. It’s the only way to drown out the noise from the wood mill bordering his backyard, the jackhammer sound of the plant piercing his walls and windows. The 18-wheelers carrying logs rumble by less than 100 feet from his house, all day and night, shaking it as if an earthquake has taken over this tranquil corner of North Carolina. He’s been wearing masks since long before the coronavirus pandemic, just to…

The dark side of solar power

The dark side of solar power

Atalay Atasu, Serasu Duran, and Luk N. Van Wassenhove write: It’s sunny times for solar power. In the U.S., home installations of solar panels have fully rebounded from the Covid slump, with analysts predicting more than 19 gigawatts of total capacity installed, compared to 13 gigawatts at the close of 2019. Over the next 10 years, that number may quadruple, according to industry research data. And that’s not even taking into consideration the further impact of possible new regulations and…

Biden administration approves nation’s first major offshore wind farm

Biden administration approves nation’s first major offshore wind farm

The New York Times reports: Construction on the nation’s first commercial-scale offshore wind farm is expected to begin this summer, after the Biden administration gave final approval Tuesday to a project it hopes will herald a new era of wind energy across the United States. The Vineyard Wind project calls for up to 84 turbines to be installed in the Atlantic Ocean about 12 nautical miles off the coast of Martha’s Vineyard, Mass. Together, they could generate about 800 megawatts…

Push to electrify mail trucks gains wide support, an unlikely win for both DeJoy and Biden

Push to electrify mail trucks gains wide support, an unlikely win for both DeJoy and Biden

The Washington Post reports: House Democratic leaders are lining up behind a White House push to allocate $8 billion in taxpayer funding for the latest iteration of mail truck, paving the way for a fully electric fleet instead of the piecemeal strategy U.S. Postal Service leaders have been pursuing. The agency, which is generally self-sustaining and does not draw public money, has drawn up a bootstrap plan for new vehicles — the vast majority of which would run on gas…

Washington State plans to phase out new gas cars by 2030

Fast Company reports: The U.K. plans to ban new fossil-fuel-powered cars by 2030. The Netherlands and Germany have the same goal. Now the state of Washington plans to follow, making it the first in the U.S. to move as quickly to phase out polluting cars. In nine years, if you want to buy a new car or light truck in Washington, it will have to be electric. “When you really look at the issue, there’s not any single factor that…

Electric cars’ looming recycling problem

Electric cars’ looming recycling problem

By Perry Gottesfeld In September, Tesla announced that it would be phasing out the use of cobalt in its batteries, in an effort to produce a $25,000 electric vehicle within three years. If successful, this bold move will be an industry game changer, making electric vehicles competitive with conventional counterparts. But the announcement also underscores one of the fundamental challenges that will complicate the transition to electric vehicles. Without cobalt, there may be little financial incentive to recycle the massive…

Why Texas Republicans fear the Green New Deal

Why Texas Republicans fear the Green New Deal

Naomi Klein writes: Since the power went out in Texas, the state’s most prominent Republicans have tried to pin the blame for the crisis on, of all things, a sweeping progressive mobilization to fight poverty, inequality and climate change. “This shows how the Green New Deal would be a deadly deal,” Gov. Greg Abbott of Texas said Wednesday on Fox News. Pointing to snow-covered solar panels, Rick Perry, a former governor who was later an energy secretary for the Trump…
