The U.S. Department of Energy (DOE) began accepting letters of interest from applicants for loans under a new $2.1 billion Carbon Dioxide Transportation Infrastructure Finance and Innovation (CIFIA) program.

Supercritical carbon dioxide can get much hotter than steam - up to 700°C. It can potentially be used in a Brayton cycle which has the potential to be much more efficient at turning heat from power plants into energy than the traditional steam-based Rankine cycle used in today's thermal power plants.

In 2021, U.S. energy-related carbon dioxide (CO2) emissions increased by 296 million metric tons (MMmt), or 6%, compared with 2020 levels.

CO2 emissions from power generation thus rose by 13% in 2021, though remaining within the path of the Climate Protection Act.

Global energy-related carbon dioxide (CO2) emissions will increase for countries both inside and outside of the Organization for Economic Cooperation and Development (OECD) over the next 30 years under current laws and regulations.

The bill is a first step to create legislation that will allow to regulate CO2 emissions in Russia.

"Global carbon emissions are set to jump by 1.5 billion tonnes this year -- driven by the resurgence of coal use in the power sector. This is a dire warning that the economic recovery from the COVID crisis is currently anything but sustainable for our climate," said Fatih Birol, the IEA's executive director.

"Germany has achieved its 2020 climate target," Economy and Energy Minister Peter Altmaier said. Compared to 1990, 2020 emissions dropped 40.8%.

After hitting a low in April, global emissions rebounded strongly and rose above 2019 levels in December.

Economic growth and the lessening of pandemic-related restrictions result in more energy consumption and associated CO2 emissions. EIA expects total energy-related CO2 emissions to increase to 4.8 billion metric tons in 2021 and 4.9 billion metric tons in 2022.
