Rhodium Group estimates US GHG fell 2.1% in 2019, driven by coal decline

Green Car Congress

The Rhodium Group, an independent research provider, estimates that, after a sharp uptick in 2018, US greenhouse gas (GHG) emissions fell by 2.1% This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. Coal-driven decline.

Monash team proposes roadmap to renewable ammonia economy; 3 generations of technology

Green Car Congress

While there is global potential to generate renewable energy at costs already competitive with fossil fuels, a means of storing and transporting this energy at a very large scale is a roadblock to large-scale investment, development and deployment. Generation 2 moves the Haber-Bosch process to renewable sources of hydrogen.

EPA GHG Inventory shows US GHG down 1.7% y-o-y in 2019, down 13% from 2005

Green Car Congress

The US Environmental Protection Agency (EPA) released its 28 th annual Inventory of US Greenhouse Gas Emissions and Sinks (GHG Inventory), which presents a national-level overview of annual greenhouse gas emissions from 1990 to 2019. The number of vehicle miles traveled (VMT) by light-duty vehicles (i.e., from 2018 to 2019.

Proposed process for low-emissions coal-to-liquids

Green Car Congress

The EMS (Earth and Mineral Science) Energy Institute at Penn State has developed a conceptual novel process configuration for producing clean middle-distillate fuels from coal with some algal input with minimal emissions. Principal inputs are coal, water, non-carbon electricity, and make-up solvent. Background.

Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses.

Liquid Light unveils cost-advantaged catalytic process to make chemicals from CO2

Green Car Congress

Liquid Light unveiled its new process for the production of major chemicals from carbon dioxide, showcasing its demonstration-scale “reaction cell” and confirming the potential for cost-advantaged process economics. Other processes require an estimated $617 to $1,113 of feedstocks derived from oil, natural gas or corn.

At the same time, total miles traveled per year by cars, sport utility vehicles (SUVs) and light trucks will increase about 60%, reaching about 14 trillion in 2040. As personal mobility increases, average new-car fuel economy (including SUVs and light trucks) will improve as well, rising from about 30 miles per gallon (7.83
