IPG to demo Flameless Ceramic Turbine for clean, off-grid power in EV charging

Green Car Congress

But, in many high-use areas and remote locations, upgrading grid connections to meet future charging demand is not practical or commercially viable. IPG‘s flameless combustor uses the turbine exhaust and high heat transfer effectiveness through the IPG regenerator unit. —IPG CEO Toby Gill.

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.

Environment Canada/MECA team assesses black carbon emissions in GDI engine exhaust; evaluation of prototype gasoline particulate filter

Green Car Congress

In addition, the inhomogeneity of the fuel mixture under stratified operation in GDI engines during the compression stroke tends to contribute to higher particulate emissions compared to the exhaust emissions from traditional PFI engines. Ford Transit Connect PFI vehicle (PFI#2). —Chan et al. The midsize sedans were a 2011 2.4L

NSF and DOE form Partnership on Advanced Combustion Engines; goal 25-40% better LDV fuel economy and 55% BTE in heavy-duty engines; $12M in awards for FY 2012-2014

Green Car Congress

The high-level performance goals of the Partnership are a 25-40% improvement in fuel economy in a light-duty vehicle (LDV) and achieving 55% brake thermal efficiency (BTE) in heavy-duty engine systems. bio-derived) fuels have the potential to dramatically increase fuel economy. The potential is significant.
