Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon. —Mark Jacobson.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3–11% (5–24¢ per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.

Study: 25% EV adoption would save US $17B annually from avoided climate change & pollution damages

Green Car Congress

A new study led by researchers from Northwestern University projects that if electric vehicles replaced 25% of combustion engine cars currently on the road, the United States would save approximately $17 billion annually by avoiding damages from climate change and air pollution. The open-access paper is published in AGU’s journal GeoHealth.

BloombergNEF forecasts green hydrogen should be cheaper than natural gas by 2050 in some markets; falling costs of solar PV key

Green Car Congress

In a new piece of research, BloombergNEF (BNEF) finds that the levelized cost of hydrogen (LCOH 2 ) made from renewable electricity is set to fall faster than it previously estimated. These costs are 13% lower than BNEF’s previous 2030 forecast and 17% lower than its old 2050 forecast. MMBtu) by 2050 in most modeled markets.

IEA: Decisive action by governments is critical to unlock growth for low-carbon hydrogen

Green Car Congress

Governments need to move faster and more decisively on a wide range of policy measures to enable low-carbon hydrogen to fulfil its potential to help the world reach net zero emissions while supporting energy security, the International Energy Agency (IEA) says in a new report. —Fatih Birol, the IEA Executive Director.
