This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. unusually high electrical conductivity and Raman spectra of these materials demonstrated in the linked Data in Brief paper are that of multi-walled carbon nanotubes, and are due to the morphology as demonstrated by TEM.
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
An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge.
Audi will introduce the compact A3 Sportback g-tron—which can be powered by the CO 2 -neutral Audi e-gas, synthetic methane generated from eco-electricity in the Audi e-gas project ( earlier post )—at the end of the year. The e-gas fuel will be produced in the power-to-gas plant in Werlte, Germany.

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.
The US and China jointly announced greenhouse gas (GHG) reduction targets. US President Barack Obama said the US will cut net greenhouse gas emissions in the US by 26-28% below 2005 levels by 2025. Together, the US and China account for more than one third of global greenhouse gas emissions.
BER [Berlin Brandenburg Airport] is an ideal partner as it possesses the world’s first CO 2 neutral gas station. The Total gas station provides green hydrogen produced from wind energy by Enertrag. Opel is further expanding its market trial with hydrogen fuel cell vehicles with a HydroGen4 vehicle going to the Berlin Airports.
The process developed by SunFire begins with the decomposition of water into hydrogen and oxygen by using electrolysis, driven by renewable electrical energy (derived from sunlight, wind or water). more than two-thirds of the electrical energy used reappears in the fuel produced. Approximately 2.6 kg of carbon dioxide and 1.1
Other processes require an estimated $617 to $1,113 of feedstocks derived from oil, natural gas or corn. Liquid Light’s process also reduces the overall carbon footprint for chemical production compared to conventional methods, when powered with electricity produced from natural gas, nuclear, advanced coal and renewable sources.
The results show that electromethanogenesis can be used to convert electrical current produced from renewable energy sources (such as wind, solar, or biomass) into a biofuel (methane) as well as serving as a method for the capture of carbon dioxide. We actually find very little hydrogen in the gas phase in nature. Cheng et al.
The material’s selectivity for oxygenates, with ethanol as the major product, demonstrates the feasibility of a two-step conversion of CO 2 to liquid fuel that could be powered by renewable electricity, the team suggests in their paper published in the journal Nature.
Natural gas emerged as the fuel of choice, posting the biggest gains and accounting for 45% of the rise in energy consumption. Gas demand growth was especially strong in the United States and China.
