DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

estimated that with conversion by hydrothermal liquefaction (HTL) and upgrading, the wet waste resource availability in the United States could be converted to jet fuel that is equivalent to about 24% of the U.S. Skaggs et al. demand in 2016. —Ou et al. GLE and $0.9/GLE.

Wärtsilä report finds accelerated adoption of renewables can reduce electricity production costs by up to 50%

Green Car Congress

The Front-Loading Net Zero report states that electricity production costs could be reduced by up to 50% by 2050 if countries and states adopt 100% renewable systems faster than currently planned. Utilities should keep repeating steps 1 - 3 until their systems run on 80 – 90% renewables.

Bombardier (now Alstom) to convert AGC hybrid trains to full battery power

Green Car Congress

To help France meet its sustainability targets, Bombardier will now convert AGC hybrid trains to full battery power. The idea is to convert dual-mode (catenary and diesel-powered) high capacity self-propelled trains to dual-mode battery-powered AGCs.

IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

Renewable energy sources are central to the energy transition toward a more sustainable future. While there are many effective solutions for daily energy storage, the most common being batteries, a cost-effective long-term solution is still lacking. An open-access paper on the work is published in the journal Energies.

Lightning Systems converting 35-foot diesel buses to battery-electrics in Boulder; cost-effective electrification

Green Car Congress

This project will be the first step for the City of Boulder and Via in realizing their combined goal of converting the HOP fleet of 35-foot transit buses to all-electric vehicles. Repowering an existing diesel transit bus with the LightningElectric product will cost one-third the price of a new electric bus.

EU project HyFlexFuel converted sewage sludge and other biomasses into kerosene by hydrothermal liquefaction (HTL); SAF

Green Car Congress

The decarbonization of the transportation sector will require large volumes of renewable fuels. So far, renewable diesel and jet fuels are mainly derived from plant oils, but the EU Renewable Energy Directive limits the use of biofuel from food and feed crops since they do not meet sustainability requirements when produced at large scale.
