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.

PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

Researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a new method to convert captured CO 2 into methane, the primary component of natural gas. Different methods for converting CO 2 into methane have long been known.

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.

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

Green Car Congress

However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. While there are many effective solutions for daily energy storage, the most common being batteries, a cost-effective long-term solution is still lacking.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

The California-based Hyperlight Energy will be piloting an installation where they plan to use existing oil wells as solar thermal wellsprings, with the stored energy being converted back to clean electricity when required. But we can still reduce the carbon [cost] of that oil.” to test the concept for the first time.

Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

To meet this challenge and to satisfy the constant energy demand of society, electricity must be stored in times of overproduction to provide energy when little sunshine and wind is available. To store the green electricity in a highly scalable way, it must be converted into chemical energy. Diess et al.

Fraunhofer working on optimized methanol reformers to deliver hydrogen

Green Car Congress

Methanol reformers convert easy-to-transport methanol into hydrogen. Converting hydrogen into methanol can provide a solution, as not only is methanol much easier to transport than hydrogen, it can also be stored almost unlimited at ambient pressure. Transporting hydrogen can be a complex process. © Fraunhofer IMM.
