Fuel From Wind And Water | Earth Wise

February 21, 2023 By EarthWise 1 Comment

Hydrogen is the most common element in the universe and it can be used as a fuel to run cars, trains, and even airplanes. Using it produces no harmful emissions. However, to date, the way it is economically produced is not clean and green. It is made from natural gas and leaves behind lots of carbon dioxide.

Around the world there are many projects working on so-called green hydrogen. Producing hydrogen by splitting water into its component elements is called electrolysis and produces only oxygen as a waste product. The problem with electrolysis is that it takes prodigious amounts of energy and therefore is very expensive.

A new project taking place in north Texas hopes to create the country’s first large-scale producer of green hydrogen. The project is building a 900-megawatt wind farm along with a 500-megawatt solar farm. The 1.4 gigawatts of total production capacity is more energy than the city of Austin consumes. That energy will be used to produce 200,000 kilograms of hydrogen a day.

This project is among the largest proposed green hydrogen projects in the U.S. There are green hydrogen proposals in Europe, Australia, Africa, and the Middle East that range from 10 GW to 67 GW.

The Texas project, being developed in partnership by Air Products and AES, has been enabled by government support from the Inflation Reduction Act.

There are a few thousand hydrogen-powered cars, boats, and trains but without substantial, cost-effective hydrogen infrastructure, the market is very limited. Subsidizing the development of the necessary infrastructure is essential if there is any real chance to create the long-imagined hydrogen economy.

Electric Vehicle Tax Credits | Earth Wise

February 17, 2023 By EarthWise Leave a Comment

As of January 1, many Americans can qualify for a tax credit of up to $7,500 for buying an electric vehicle. The credit is one of the changes enacted under last year’s Inflation Reduction Act. The purpose is to encourage EV sales and thereby reduce greenhouse gas emissions and air pollution.

There has been a tax credit for EVs for more than a decade, but its provisions made cars from any manufacturer ineligible as soon as that manufacturer had sold more than 200,000 cars. Notably, this eliminated the credit for purchasing cars from Tesla and General Motors. Given that electric cars are now selling in the millions, the 200,000-unit cap on the tax credit essentially made it useless as a real force to grow the industry.

The new tax credit has a somewhat complex set of requirements for determining the applicability and amount of the credit. There are price limits on eligible vehicles depending on vehicle type and there are requirements on where vehicles are manufactured, where batteries are manufactured, and where other components are made. The intent is to encourage American manufacturing of the cars and trucks to the greatest extent. There are also income limitations on buyers who want to take advantage of the credit, but those are quite large. The Department of the Treasury has online detailed information about the requirements for the credit and, of course, EV manufacturers can provide the specifics for their own vehicles.

For their part, automakers are adjusting prices, building domestic manufacturing plants and battery factories, and otherwise trying to position themselves for their customers to take advantage of the credit.

The new law also provides a smaller tax credit for the purchase of used electric vehicles.

A Complicated Year For Energy | Earth Wise

February 6, 2023 By EarthWise Leave a Comment

2022 was a complicated year for global energy. Following its invasion of Ukraine, Russia curtailed natural gas exports to Europe. This led to large increases in coal burning in many countries, but at the same time led to major new investments in renewable energy. Projections are that the world will add as much renewable power in the next five years as it did over the previous 20.

In China, severe drought reduced the amount of available hydropower, which drove increased demand for coal in that country. Between the war in Ukraine and the Chinese drought, coal burning reached an all-time high in 2022, albeit only a 1% uptick for the year. This increased coal consumption is expected to be only temporary as the accelerating deployment of renewables, energy efficiency, and the use of heat pumps will inexorably reduce coal use.

Globally, governments have earmarked an additional $500 billion for clean energy just since March, bringing the total since the onset of the COVID pandemic to more than $1.2 trillion. Nearly half of this total investment comes from the U.S. under the Inflation Reduction Act and the Infrastructure Investment and Jobs Act.

In light of these energy policies around the world, the International Energy Agency has revised its projections for renewable energy to substantially larger numbers. Renewables are expected to surpass coal as the world’s largest source of electricity by early 2025. The global energy crisis triggered by the war in Ukraine has kicked off an extraordinary new phase of rapid renewables growth as countries around the world are seeking to obtain energy security as well as the other benefits of clean energy.

The Race For EV Batteries | Earth Wise

February 1, 2023 By EarthWise Leave a Comment

Lithium-ion batteries have been the power source for electric vehicles since 2008, when the Tesla Roadster was introduced. They took over for nickel-metal hydride batteries that powered most hybrid electric cars such as the Prius. Lithium-ion batteries store much more energy for a battery of a given weight, which leads to greater driving range.

But lithium-ion is not an ideal solution. The batteries depend on critical materials that are obtained by hacking into mountains, utilizing scarce desert groundwater, and in some cases, making use of child labor. Many materials depend on countries with whom economic ties have complicated geopolitical consequences.

State and federal mandates and incentives are pushing auto companies to prioritize electric vehicles in their future plans. The Inflation Reduction Act in particular provides credits and other incentives for both consumers and manufacturers to electrify. So, sources for EV batteries are a key issue.

The Department of Energy is funding 20 different companies with $2.8 billion to bolster the production and processing of critical minerals in the U.S. The goal is to bring the electric vehicle supply chain onshore to the greatest extent possible. Some of the work involves redesigning lithium-ion batteries to reduce or eliminate problematic materials such as cobalt. Other efforts seek to find domestic sources of critical materials such as lithium without causing serious environmental problems.

Given all this, it is no surprise that academic and industrial researchers are also exploring a wide variety of alternative battery technologies.

The future of transportation is electrification and the race for EV batteries is on.

Electric Mail Trucks | Earth Wise

January 26, 2023 By EarthWise Leave a Comment

The US Postal Service recently announced that it plans to buy at least 66,000 electric vehicles by 2028. With more than 231,000 total vehicles, the Postal Services operates one of the largest civilian vehicle fleets in the world.

Last February, the Postal Service announced a plan to replace up to 165,000 older mail trucks, many of which are as much as 30 years old. The gas-powered trucks get an estimated 8.6 miles per gallon when air conditioning is running. The plan was for only 10% of the new trucks to be electric, citing the high upfront costs of electric vehicles even though they generally make up the difference by saving on fuel and maintenance costs over time.

Facing strong criticism from the Biden administration, the Postal Service shifted course and in July announced that 40% of the new trucks would be electric. With passage of the Inflation Reduction Act in August, the Postal Service received $3 billion for fleet electrification and has once again changed its plans. It also announced that it intends to stop buying gas-powered delivery trucks altogether after 2026.

As part of the new plan, the Postal Service plans to upgrade hundreds of facilities across the country to accommodate electric vehicles. This will include installing chargers and streamlining delivery operations to reduce unnecessary trips.

The Postal Service is no alone in working to clean up its fleets. FedEx says it plans to completely electrify its pickup and delivery fleet by 2040. Amazon has ordered 100,000 electric vans from the start-up company Rivian.

Electrifying the postal delivery system makes abundant sense. Postal routes are predictable and there is ample charging time to meet the power needs of the fleet.

Carbon Capture In Wyoming | Earth Wise

January 25, 2023 By EarthWise Leave a Comment

Wyoming produces about 40% of our country’s coal and many towns in the state were built because of and make their living from it. With coal’s plummeting share in the nation’s electricity, there is a great deal of anxiety among residents of those towns.

As carbon dioxide levels in the atmosphere continue to climb, there is a growing sense that cutting emissions will not happen quickly enough and it will be necessary to pull the greenhouse gas out of the atmosphere. The current long-term government climate strategy assumes that carbon removal will account for 6 to 8 percent of the nation’s greenhouse gas reductions by 2050.

The Inflation Reduction Act passed in August provides $3.5 billion to help build “direct air capture hubs” around the country, with an emphasis on fossil fuel-dependent communities such as many in Wyoming.

The town of Rock Springs, Wyoming is home to the Jim Bridger Coal Plant. A company called CarbonCapture, Inc., is launching Project Bison, which will build a direct air capture facility outside of town that is set to begin operations next year. It will initially capture 10,000 metric tons of CO2 per year but plans to expand that to 5 million tons a year by 2030.

That would be far more than any current carbon capture plant can do. The largest plant in the world, located in Iceland, pulls in only about 4,000 metric tons a year.

There are many problems associated with carbon capture. It uses up very large amounts of energy, possibly presents environmental problems, and is very expensive. In short, the technology has a long way to go before becoming viable. However, this may ultimately be another example where necessity is the mother of invention.

Green Steel | Earth Wise

October 5, 2022 By EarthWise Leave a Comment

The Inflation Reduction Act provides $369 billion in investments to ramp up renewable energy generation and manufacturing of solar panels, wind turbines, energy storage, and electric vehicles.

Every megawatt of solar power deployed requires 35 to 45 tons of steel. Every megawatt of wind power uses 120 to 180 tons of steel. Estimates are that it will take 1.7 billion tons of steel just to build all the wind turbines needed to reach net zero emissions by 2050.

This is a big problem because steel production accounts for roughly 10% of global carbon emissions and is one of the most carbon-intensive industries in the world.

Making steel is a complex and age-old process that hasn’t changed much over time. Green steel is steel made with little or no carbon emissions. There are a few ways to do it. One is called the direct reduced iron method that uses green hydrogen instead of fossil fuel gas to produce iron and then a renewable-powered electric arc furnace to make the steel.

Molten Oxide Electrolysis is an alternative green steel approach that doesn’t depend on having a green hydrogen infrastructure. It uses electrolysis, powered by renewable energy, to separate the bonds of iron ore and produce liquid metal while releasing only oxygen in the process.

Green steel solutions rely on the availability of renewable energy, but the ultimate success of renewable energy will depend on the success of green steel. The U.S. steel industry will leverage about $6 billion under the Inflation Reduction Act to make progress on it.

A Cheap Material For Carbon Capture | Earth Wise

September 12, 2022 By EarthWise Leave a Comment

The recently passed Inflation Reduction Act includes significant support for carbon capture technologies. Eliminating fossil fuel burning is essential for halting climate change, but in the interim, methods for capturing emissions of carbon dioxide and either storing it or turning it into usable products are increasingly necessary.

There are a variety of techniques being developed for carbon capture but at this point, none of them are commercially viable. The best technique in use today involves piping flue gases through chemicals called liquid amines, which bind CO2. The process requires large amounts of energy to release the bound carbon dioxide so it can be concentrated and stored. As a result, it is complicated and expensive.

Researchers at UC Berkeley, Stanford, and Texas A&M University have developed a carbon capture method using melamine, which is an inexpensive polymer used to make Formica, as well as low-cost dinnerware, industrial coatings, and other plastics. Porous melamine itself adsorbs CO2 to a limited extent. But the researchers discovered that adsorption could be much improved by adding the chemical DETA (diethylenetriamine) to bind the CO2. In addition, adding cyanuric acid increased the melamine pore size and radically improved CO2 capture efficiency even more.

The result is a material that is more efficient even than exotic carbon capture materials like metalorganic frameworks and is much cheaper and easier to make. The researchers aim to design equipment that can used in industrial facilities, attached to buildings and other structures, or even to the tailpipes of gas-powered vehicles.

A Law To Tackle Climate Change | Earth Wise

September 8, 2022 By EarthWise Leave a Comment

The Inflation Reduction Act signed into law in mid-August is the most comprehensive U.S. legislation addressing climate change ever enacted. It contains $369 billion in funding for clean energy and electric vehicle tax breaks, domestic manufacturing of batteries and solar panels, and pollution reduction.

The legislation for the most part makes use of carrots rather than sticks to coax American consumers and industry away from reliance on fossil fuels. Rather than establishing more carbon taxes, mandates, and penalties, the law largely makes use of tax credits to provide incentives for the use of clean energy.

The law provides a large mix of tax breaks intended to bring down the costs of solar, wind, batteries, electric cars, heat pumps, and other clean technology. For example, consumers will get a $7,500 credit for purchasing many new electric car models and about $4,000 for buying a used vehicle.

On the stick side of the ledger, oil and gas companies that emit methane above certain threshold levels will incur fees that escalate over time. The law also increases the cost to the oil industry for extracting fossil fuels from public lands.

The act provides $60 billion for overall environmental justice priorities, including $15 billion targeted specifically for low-income and disadvantaged communities. There are many other provisions in the law addressing multiple climate-related issues.

According to three separate analyses by economic modelers, the investments from the Inflation Reduction Act are likely to cut pollution by about 40% below 2005 levels by the year 2030.
