Heating Buildings With Solar Energy Stored in Sand

Cars That Think

When we turn up the heat in our homes and workplaces, we must balance our personal need for warmth with the global impact of burning fossil fuels like oil, gas, coal, and biomass. Out of Finland’s energy-related emissions, 82 percent come from heating domestic buildings (Ref. The apparent contradictions do not end there.

Researchers in Netherlands exploring use of lignin as alternative asphalt binder

Green Car Congress

These include a section of road on an industrial site—used daily by cars and heavy trucks, some minor roads, and a cycle path at Wageningen University & Research, which is in three sections, each produced using a different lignin-based bio-bitumen. Bitumen is a very thick liquid form of crude oil.

Asphalt binder, the sticky “glue” that holds crushed stone and sand together to form pavement, only accounts for about 5% percent of the final hot mix asphalt (HMA) that is steamrolled into glossy new lanes and boulevards. Building roads is a big investment in taxpayer money. —Haifang Wen.

DOE to Award Honeywells UOP $25M for Pyrolysis Oil to Renewable Fuels Demo Unit

Green Car Congress

The US Department of Energy has selected UOP, a Honeywell company, for negotiation of a $25 million award to build a demonstration unit in Hawaii to convert cellulosic biomass into renewable hydrocarbon transportation fuels. RTP rapidly heats biomass at ambient pressure to generate high yields of pourable, liquid pyrolysis oil.

National Low Carbon Fuel Standard study releases major Technical Analysis and Policy Design reports; providing a scientific basis for policy decisions

Green Car Congress

Building on LCFS policies already adopted in Europe, British Columbia, and California, the researchers looked at potential costs and benefits of reducing the carbon intensity of transportation fuels by 10 to 15 percent by 2030. We did not shy away from controversy. We are not advocates.
