It does this by reacting with dissolved CO 2 in the soils water, turning it into bicarbonate ions and preventing it from returning to the atmosphere (see the side bar for more detail). As rocks are worn away (or weathered) by this slightly acidic water, silicate minerals in the rock dissolve.
Last November , w hen Azerbaijan hosted COP29 , the United Nations annual climate summit , i t was a sort of coming-out party for the country. But i n a side room away from media attention, a different climate discussion concluded more auspiciously. In November, Baku hosted the 29th annual United Nations Climate Change Conference.
Itaipus massive scale By the late 1960s, Brazil and Paraguay recognized the Paran Rivers untapped hydroelectric potential, according to the Global Infrastructure Hub. By harnessing 62,200 cubic meters of river water per second, Itaipu prevents the release of nearly 100 million tonnes of carbon dioxide each year.
In hydrogen electrolysis, the membrane helps split water by separating hydrogen from oxygen. These companies, and several others globally, are betting on AEM technology to fulfill the long-sought promise of green hydrogen produced with renewable energy. So far, AEM has only been deployed at a small scale.
The global push toward sustainability and reducing greenhouse gas emissions is steering the transportation sector into a new era of innovation. The Rise of Fuel Cell Electric Buses Fuel cell electric buses are powered by hydrogen fuel cells that convert hydrogen gas into electricity, producing water vapor as the only byproduct.
As climate change accelerates and fuel prices remain volatile, electric vehicles (EVs) have quickly gained traction among consumers looking for a more sustainable and cost-efficient way to drive. According to Reuters, global sales of electric vehicles were up by over 25.6% is an avid collector of expensive things.
A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. A global warming potential of 11.6 Sand et al.

Schematic overview of the processes by which aviation emissions and increased cirrus cloudiness affect the climate system. Aviation accounts for 3.5%
billion people in 2050 will live in water-stressed areas. The researchers also expect about 1 billion more people to be living in areas where water demand exceeds surface-water supply. A large portion of these regions already face water stress—most notably India, Northern Africa and the Middle East. Schlosser, C.A.,
The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.
Electrolytic hydrogen production powered by renewable energy is seen as an environmentally friendly means to ameliorate globalclimate and energy problems. Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. Zhang, S.L., and Lou, X.W.
The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.

Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. The results are published in an open-access paper in the Nature Partner Journal (npj) Climate and Atmospheric Science. Burkhardt et al. —Ulrike Burkhardt.
The first large-scale study of the risks that countries face from dependence on water, energy and land resources has found that globalization may be decreasing, rather than increasing, the security of global supply chains. This interconnectedness also increases the amount of risk at each step of a global supply chain.
Globally 131 million tons of ammonia were produced in 2010. Globally 245 million tons of CO 2 were released by the ammonia industry in 2010 equivalent to about 50% of the UK CO 2 emissions (495.8 is well known that some higher plants can synthesize ammonia or its derivatives directly from air and water at room temperature.
The target train passing by The Kelpies —30-meter-high horse-head sculptures depicting kelpies (mythical Celtic water horses which could transform their shape and which were reputed to have the strength of 10 horses and the endurance of many more), in Grangemouth near Falkirk. —Transport Secretary Michael Matheson.
In California, reductions in emissions of black carbon since the late 1980s—mostly from diesel engines as a result of air quality programs—have resulted in a measurable reduction of concentrations of global warming pollutants in the atmosphere, according to a study examining the impact of black carbon on California’s climate.
trillion in 2010) would be required to overcome poverty; increase food production to eradicate hunger without degrading land and water resources; and avert the climate change catastrophe. A comprehensive global energy transition is urgently needed in order to avert a major planetary catastrophe.
Researchers at Stanford University, with colleagues at Oak Ridge National Laboratory and other institutions, have developed a nickel-based electrocatalyst for low-cost water-splitting for hydrogen production with performance close to that of much more expensive commercial platinum electrocatalysts.

Among the transportation-related elements of US President Barack Obama’s new climate action plan, which he is outlining today in a speech at Georgetown University, is the development of new fuel economy standards for heavy-duty vehicles post-2018. Preparing the US for the impacts of climate change. Earlier post.).
earlier post ), a new study by a team at Environmental Defense Fund finds that the climate impact of hydropower facilities varies widely throughout the world and over time, with some facilities emitting more greenhouse gases than those burning fossil fuels. They also estimated emissions caused by flooding the reservoir.
KPMG developed 3 nexuses linked by climate change to represent the challenges of sustainable growth. In a new study, KPMG International has identified 10 “megaforces” that will significantly affect corporate growth globally over the next two decades. Source: KPMG. Click to enlarge.
The Paris Agreement calls for global warming to be limited to 2 ?C First, apply electricity generated from renewable sources to obtain hydrogen from water. Climate neutrality. Vehicles on the road, when powered by synthetic fuel, are ultimately climate-neutral. C above pre-industrial levels, and preferably 1.5 °C.
Together, the US and China account for more than one third of global greenhouse gas emissions. The Administration said the United States will submit its 2025 target to the Framework Convention on Climate Change as an “Intended Nationally Determined Contribution” no later than the first quarter of 2015.
Driven particularly by the demand of the e-mobility sector, Europe’s share of global battery cell production is forecast to reach almost 15% by 2024, overtaking the US and Asia excluding China. Europe is already the fastest growing lithium-ion battery production center in the world, with zero local supply of lithium hydroxide.
announced its next environmental sustainability strategy—PLANET 2050—which includes science-based goals that meet or exceed the goals in the United Nations Paris agreement on climate change. Reduce absolute water consumption in facilities and operations by 30%. Cummins Inc.
This is an important development because there is little time available to reduce CO 2 emissions sufficiently to avoid the worst effects of climate change. The conversion of CO 2 to fuels in these inexpensive water-based systems has shown high faradic efficiencies for reduction of CO 2. to C 2 fuel products such as ethanol.

Today, here in the South Bay of Los Angeles where I live, we have all the dots you’d ever need to connect the crisis level of global warming to the urgent action needed locally. If we continue our head-in-the-sand, business as usual path, we are headed straight for runaway, uncontrollable destruction of our livable climate.
Nel Hydrogen Electrolyser AS, a division of Nel ASA, has received a purchase order for a 20MW alkaline water electrolyzer from Ovako , a leading European manufacturer of engineering steel.
