Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

An important consideration of solar-electrolysis in the context of climate mitigation is the enormity of upscaling required—both at the global scale with respect to the investment, land area, materials, and embodied energy; and at the project scale with respect to the potential localised impacts of gigawatt scale plants. Palmer et al.

ARB: carbon intensity of biomethane from wastewater sludge could be as low as -65.27 g CO2e/MJ

Green Car Congress

Grid-based electricity, using the California-Marginal mix of electrical generating assets, is assumed to power the wastewater sludge treatment, and biogas cleaning, compression, and fuel dispensing processes. In this model, only a small parasitic load on the biogas produced is used to heat the digesters. Background.

Audi unveils e-gas project: synthetic methane from the methanation of green hydrogen; series production of CNG models in 2013 powered by e-gas

Green Car Congress

Audi A3 TCNG for e-gas project. Starting in 2013, Audi will begin series production of TCNG models whose engines—derived from TFSI units—will be powered by e-gas: synthetic methane produced via the methanation of hydrogen produced by electrolysis using renewable electricity. Click to enlarge.

IRENA, IEA study concludes meeting 2?C scenario possible with net positive economics

Green Car Congress

The Paris Agreement reflected an unprecedented international determination to act on climate. The focus must be on the decarbonization of the global energy system as it accounts for almost two-thirds of greenhouse gas emissions. Primary CO 2 emissions reduction potential by technology in the Reference Case and REmap, 2015-2050.

Study: even with high LDV electrification, low-carbon biofuels will be necessary to meet 80% GHG reduction target; “daunting” policy implications

Green Car Congress

The same highly electrified scenarios, however, could not satisfy 80% GHG-reduction targets, even assuming 80% decarbonized electricity and no growth in travel demand. Within the transportation sector, the two basic options for reducing petroleum use and greenhouse gas (GHG) emissions are fuel-use reduction and fuel substitution.
