Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

Driven by rising natural gas and oil consumption, levels of CO 2 are expected to hit 37 billion metric tons this year, according to new estimates from the Global Carbon Project (GCP), an initiative led by Stanford University scientist Rob Jackson. and China account for more than half of all carbon dioxide emissions globally.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas.

3 Oil Majors That Bet Big On Renewables

Green Car Congress

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. Good case in point: Italian multinational oil and gas giant Eni S.p.A. 2 Total SA. 2 Total SA.

BNEF: wind and solar boost cost-competitiveness versus fossil fuels

Green Car Congress

This year has brought a significant shift in the generating cost comparison between renewable energy and fossil fuels, according to detailed analysis by technology and region, published this week by Bloomberg New Energy Finance. —Seb Henbest, head of Europe, Middle East and Africa at BNEF.

U Delaware team develops prototype efficient direct ammonia fuel cell for transportation

Green Car Congress

With recent and projected cost declines in wind, solar, and lithium-ion batteries, electrification using batteries has become a viable option for applications compatible with the inherent range limitations and recharging time. The technical potential of wind and solar energy is vast, and such fuels are scalable beyond foreseeable needs.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes). This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. —Ren et al.
