EIA expects that level of decrease in hydropower generation would lead to an 8% increase in California’s electricity generation from natural gas, a 6% increase in energy-related carbon dioxide (CO 2 ) emissions in the state, and an average 5% increase in wholesale electricity prices throughout the West given the current system configuration.
The first-of-its-kind device could replace conventional high-voltage breakers, which use the potent greenhouse gas sulfur hexafluoride, or SF 6. SF 6 is a fantastic insulator, but its very bad for the environmentprobably the worst greenhouse gas you can think of, says Johan Enslin , a program director at U.S.
Electrolysis offers an attractive route to upgrade greenhouse gases such as carbon dioxide (CO 2 ) to valuable fuels and feedstocks; however, productivity is often limited by gas diffusion through a liquid electrolyte to the surface of the catalyst. 2020) “CO2 electrolysis to multicarbon products at activities greater than 1 A cm -2.”
Researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a new method to convert captured CO 2 into methane, the primary component of natural gas.

This calculation includes all CO 2 emissions grouped under Scope 1 and 2 categories as set out by the Greenhouse Gas Protocol as well those associated with transporting material between production and refining sites. For the purposes of this analysis, emissions are classed as any anthropogenic sources of CO 2.
Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. Hydrogen is not a greenhouse gas, but its chemical reactions in the atmosphere affect greenhouse gases such as methane, ozone, and stratospheric water vapor.
In this reaction, solid carbon latches onto one of the oxygen atoms in carbon dioxide gas, reducing it to carbon monoxide. In the presence of carbon dioxide gas, which the team injected into the system, the graphite served the role of plucking individual oxygen atoms from carbon dioxide, reducing it to carbon monoxide.
The plant will liquefy gas from the natural gas grid to produce carbon-neutral LNG.

In 2019, CO 2 emissions from petroleum fuels—nearly half of which are associated with motor gasoline consumption—fell by 0.8%, and CO 2 emissions from the use of natural gas increased by 3.3%. Electricity generation from coal fell, and the increase in natural gas-fired electricity generation was more limited.
A methanation plant expansion to the existing power-to-gas (PtG) facility in Falkenhagen, Germany has officially opened as part of the international €28-million (US$33.5-million) While the current facility feeds pure hydrogen (“WindGas”) directly into the gas grid, the new methanation plant provides for the generation of “green” methane.
Supercritical carbon dioxide is a non-toxic, stable material that is under so much pressure it acts like both a liquid and a gas. This carbon dioxide, which stays within the system and is not released as a greenhouse gas, can get much hotter than steam—1,290 degrees Fahrenheit or 700 Celsius.
The recovery of energy demand in 2021 was compounded by adverse weather and energy market conditions—notably the spikes in natural gas prices—which led to more coal being burned despite renewable power generation registering its largest growth to date. CO 2 emissions from natural gas rebounded well above their 2019 levels to 7.5
Researchers from Newcastle University in the UK have engineered Escherichia coli bacteria to capture carbon dioxide using hydrogen gas to convert it into formic acid. The bacteria grew under gas pressure and generated formic acid from the CO 2 , said Dr. Sargent. —principal investigator Frank Sargent.
Petroleum emissions from other sectors have fallen in recent years as equipment and processes that use petroleum fuels have been replaced by those using other fuels, in particular, natural gas. Natural gas is the least carbon-intensive fossil fuel, and for decades natural gas made up the smallest portion of US energy-related CO 2 emissions.
That includes mining sites, where studies have shown that about 30% of greenhouse-gas emissions are caused by the use of diesel engines, largely in mining vehicles and power generators. The Australian market for diesel-only power generators is currently estimated to be worth around $765 million.
The TCD process starts by flowing methane gas through the patent-pending bimetallic catalyst inside a reactor vessel operating at approximately 600 ?C. The researchers then developed and demonstrated a thermocatalytic decomposition (TCD) method to separate and resynthesize the catalyst for a closed loop process.
Professor Licht says that the molten electrolysis of CO 2 process is unusual in that it sustains removal of the greenhouse gas not only from concentrated streams, such as industrial flue gases, but also (without the need for preconcentration or purification) from the air (direct air capture).

They further estimated that roughly one-fifth of the savings can be attributed to gasoline price increases over the period and four-fifths to fuel economy and greenhouse gas (GHG) standards. Their paper is published in the journal Energy Policy.
Afterwards, carbon dioxide and hydrogen are first converted into reactive synthesis gas at high temperature and then into liquid fuels in a microstructured chemical reactor. An electrolysis unit developed by Lappeenranta University of Technology (LUT) uses solar power to produce the required hydrogen.
