Deep geothermal technology can harness the heat stored beneath the Earth’s crust to make abundant zero emissions energy. Imagine, if you will, a decommissioned coal generating station sitting cold and dark. It has a direct connection to the grid, but no electrons flow because burning coal destroys the environment. But wait! What if, by some alchemy, some magic, a supply of superheated steam that is the correct temperature and pressure to make those old turbines spin again were available? And what if that steam was heated without any carbon emissions at all by the Earth’s own geothermal energy 12 miles below the surface?

New technologies would allow geothermal plants to be built in places where Earth’s heat is farther from the surface. 

A group of startups and researchers are developing technologies to expand the output of geothermal energy.

Geothermal plants produce steam from underground reservoirs of hot, porous rocks saturated with water, and channel it into electricity-making turbines or pipes that heat buildings. Although the energy is virtually free of carbon emissions, its adoption has been limited because drilling gets more expensive and more difficult as it goes deeper.

A team of researchers from the National University of Singapore (NUS) have made a serendipitous scientific discovery that could potentially revolutionize the way water is broken down to release hydrogen gas—an element crucial to many industrial processes.

The team, led by Associate Professor Xue Jun Min, Dr. Wang Xiaopeng and Dr. Vincent Lee Wee Siang from the Department of Materials Science and Engineering under the NUS College of Design and Engineering (NUS CDE), found that light can trigger a new mechanism in a catalytic material used extensively in water electrolysis, where water is broken down into hydrogen and oxygen. The result is a more energy-efficient method of obtaining hydrogen.

The Atlantic meridional overturning circulation (AMOC), a system of ocean currents that carry warm water from the tropics into the North Atlantic and transport cold water from the northern to the southern hemisphere, is a fundamental mechanism for the regulation of Earth's climate. The conveyor belt has collapsed in the past owing to natural factors. The most recent collapse played a key role in the last deglaciation. AMOC is now threatened by global warming, scientists have shown, and a new study has discovered the sequence of past breakdown events.

Automakers, industries, and governments are betting on hydrogen again. Will it work this time? 

Between the battery electrics, plug-in hybrids, and radar-festooned self-driving cars on the streets here in San Francisco, the slick red Toyota Mirai doesn’t turn many heads.

That’s despite it being one of the most technologically advanced cars in the world and one of the rarest. Since it went on sale in 2015, Toyota has sold only about 10,000 of the sedans in the United States (out of a total of approximately 290 million registered cars in the country). Yet it easily blends in with traffic.

A team of researchers from Princeton University claims that enhanced geothermal systems (EGS) could enable up to five terawatts of power generation in the U.S. alone. This is huge because, currently, the total amount of electricity produced annually in the country from all the sources stands at around one terawatt only. 

Geothermal energy is the heat that is naturally produced in the interior parts of the planet including the Earth’s crust.

Researchers in Australia have been able to use trace amounts of liquid platinum to create cheap and highly efficient chemical reactions at low temperatures, opening a pathway to dramatic emissions reductions in crucial industries.

When combined with liquid gallium, the amounts of platinum required are small enough to significantly extend the earth's reserves of this valuable metal, while potentially offering more sustainable solutions for CO2 reduction, ammonia synthesis in fertilizer production, and green fuel cell creation, together with many other possible applications in chemical industries.

TOKYO, March 8 (Reuters) – Kawasaki Heavy Industries (KHI) and other Japan-based firms said on Tuesday that a pilot project to transport hydrogen produced from brown coal in Australia to Japan in the world’s first liquefied hydrogen tanker had proven technically feasible.

While hydrogen is widely touted as a fuel of the future with zero carbon emissions, it requires intensive energy input, with renewables to produce “green hydrogen.” Critics say emissions from brown coal derived hydrogen are twice that of natural gas.

Four new pilot plants funded by the US infrastructure bill could help expand the range of the “forgotten renewable.” There’s enough heat flowing from inside the earth to meet total global energy demand twice over. But harnessing it requires drilling deep underground and transforming that heat into a usable form of energy. That’s difficult and expensive, which is why geothermal power—sometimes called the forgotten renewable—makes up only about 0.3% of electricity generation worldwide.

A global collaboration, led by researchers from UNSW, has shown how liquid gallium can be used to help achieve the important goal of net zero carbon emissions.

Engineers from UNSW have helped to discover a cheap new way to capture and convert CO2 greenhouse emissions using liquid metal.

The process can be done at room temperature and uses liquid gallium to convert the carbon dioxide into oxygen and a high-value solid carbon product that can later be used in batteries, or in construction, or aircraft manufacturing.

Curtin University research has identified a new, cheaper and more efficient electrocatalyst to make green hydrogen from water that could one day open new avenues for large-scale clean energy production.

Typically, scientists have been using precious metal catalysts, such as platinum, to accelerate the reaction to break water into hydrogen and oxygen. Now Curtin research has found that adding nickel and cobalt to cheaper, previously ineffective catalysts enhances their performance, which lowers the energy required to split the water and increases the yield of hydrogen.

Researchers at the University of Central Florida have designed for the first time a nanoscale material that can efficiently split seawater into oxygen and a clean energy fuel — hydrogen.

The material offers the high performance and stability needed for industrial-scale electrolysis, which could produce a clean energy fuel from seawater.

Hydrogen fuel derived from the sea could be an abundant and sustainable alternative to fossil fuels, but the potential power source has been limited by technical challenges, including how to practically harvest it.

Roughly 1 billion cars and trucks zoom about the world's roadways. Only a few run on hydrogen. This could change after a breakthrough achieved by researchers at the University of Copenhagen. The breakthrough? A new catalyst that can be used to produce cheaper and far more sustainable hydrogen powered vehicles.

Hydrogen vehicles are a rare sight. This is partly because they rely on a large amount of platinum to serve as a catalyst in their fuel cells—about 50 grams. Typically, vehicles only need about five grams of this rare and precious material. Indeed, only 100 tons of platinum are mined annually, in South Africa.

A thin coating of the 2-D nanomaterial hexagonal boron nitride is the key ingredient in a cost-effective technology developed by Rice University engineers for desalinating industrial-strength brine.

More than 1.8 billion people live in countries where fresh water is scarce. In many arid regions, seawater or salty groundwater is plentiful but costly to desalinate. In addition, many industries pay high disposal costs for wastewater with high salt concentrations that cannot be treated using conventional technologies. Reverse osmosis, the most common desalination technology, requires greater and greater pressure as the salt content of water increases and cannot be used to treat water that is extremely salty, or hypersaline.
