London Low Emission Zone - Feasiblility Study

Part 1 of 3 segments
Stephen Scrivens, Principal of Landscape Technology lectured at the RoGBC Green Building Training in October on key gree construction issues.
His presentation deals with:
- water issues (erosion, sedimentation control, flood risk; storm water management, water borne pollution reduction)
- site location (development density, protect/restore open space, protect ecological value of site/ reduce site disturbance; landscape & exterior design to reduce heat island effect (roof & non-roof))
- recycled materials (brownfield redevelopment, reuse of existing structures, divert from landfills; building reuse, recyclable content, rapidly renewable, local/regional content, certified wood; construction waste management, NOx emissions, composting, property maintenance, etc.)
- transportation issues (underground parking; public and alternative transportation; parking capacity and carpooling)
- water preservation and efficiency (indoor water use, water use reduction; innovative waste water technologies; external water use, water efficient landscape;contamination)
- ventilation and indoor air quality
- interior design and materials used (Interior design and furniture (low emitting materials (paints, adhesives, sealants, carpet, composite wood, agrofiber; sound insulation)
- facility management (maintenance manuals; commissioning; servicing; waste management; monitoring consumption, controlling costs).

Stephen Scrivens has lectured internationally and authored text books and over seventy articles on a range of topics including urban landscape, water management and green roofs. Stephen has an extensive background in construction project management having worked on over 150 large building projects including corporate headquarters for companies such as Glaxo, Sony, Canon and HSBC Hong Kong. He has masterplanned a number of business parks including Arlington Business Park at Theale which won the Financial Times Business Park of the Year Award. Stephen resides in Bucharest and is now developing designs for a new generation of zero-carbon eco friendly homes.

Guy Negre of MDI Air Car engine that runs on compressed air. Emissions are only filtered air that’s cleaner than outside air. 300 bars of pressure in carbon-fibre & kevlar air tanks. Car can travel at 110 km/hr and has a 150 km driving range. Refilling can be done by plugging in at home or at a special high-pressure air station. Dual-energy models use small amounts of bio-fuels that can extend the range to over 1400 kms.

Pollution free vehicle that produces zero emissions. When the car stops at traffic lights, the engine stops so no energy is lost because there’s no idling.

Technological innovation in support of the environment will be a key component of the cost-effective mitigation of the greenhouse gas emissions that contribute to global climate change. In the current policy debate, political actors appear to have accepted, more or less without examination, the original expectation of economic theorists that cap-and-trade programs (CTPs), a type of emissions trading scheme, are more supportive of innovation than traditional environmental policy instruments. This talk will discuss how economic theory and empirical studies are starting to show mixed results on this issue. It will also characterize the innovation problem in climate change, explore the potential lessons for innovation that can be gleaned from the performance of existing air quality CTPs, and consider how various CTP design features under discussion could affect the innovation problem.

It’s the hot spot at Laramie River Station, the Unit 1 boiler. Most of the time, it’s just hot. This spring, it’s hot because it’s the happenin’ place to be.

The boiler is getting a lot of attention during the unit’s maintenance outage. It’s the first of Laramie River’s three units to get a new system, called overfire air, to help reduce emissions.

(Myron Singleton/Mechanical engineer): “The overfire air project is used to reduce the NOx emissions that form at the burners. With overfire air, you divert about 15 to 20 percent of the air away from the burners, and we inject up here higher in the furnace to complete the carbon burnout.”

(Erin Huntimer): “Beneath my feet is the secondary air duct thats bringing air in from the air heaters. Part of what’s new with this project is this 72-inch diameter header duct behind me that’s redirecting air from the secondary air duct into the new overfire air ports in the boiler.”

Taking air away from the burners starves the fire for oxygen. This forces the nitrogen atoms to bond together into more stable, inert nitrogen molecules, rather than nitrogen oxide.

Planning for the outage started more than a year ago. The unit was shut down in mid April.

(Myron Singleton): “Before the outage, we started steel construction. We had quite a few modifications to make to the structural steel. And then we started construction of 72-inch diameter header ducts in February.”

The overfire air project is the first step to meet upcoming emissions rules in Wyoming being made through what is called a BART analysis. BART stands for Best Available Retrofit Technology. The next step will be installing new burners to reduce nitrogen oxide emissions even more. Each of Laramie River’s three units will get them in future outages.

(Dave mings/Environmental coordinator): “What we expect to see with overfire air and the low NOx burners completely installed is possibly a 20-25 percent reduction in NOx emissions, and we hope were going to be getting a little bit better than that. Its just going to depend on how well our older boilers that really are not designed right for this type of thing, how well our boilers and how well our operators we have some of the best operators around here if they can do their jobs to the utmost, then we hope to get that NOx down without losing a megawatt of energy.”

Another hot spot in the Unit 1 outage is the turbine deck. This is the last of the three units to get a new high-pressure/intermediate-pressure rotor and stationary blading. The project improves efficiency, meaning more megawatts without burning more fuel. The Unit 2 upgrade results in 12 more megawatts of power. Unit 3 is producing 20 more megawatts. The Unit 1 project is expected to get similar results.

Unit 1’s outage activity is winding down. The real heat returns to the boiler in early June, when operators fire the unit to bring it back online.

If we replaced half the world’s concrete production with e-crete it would save a billion tons of carbon dioxide in the next decade alone. E-crete is just one of thousands of examples of new innovation we can expect over the next five to ten years…. representing tens of thousands of new business opportunities, and billions of dollars of new revenues.

The 3.0-liter V6 dCi Concept. The V6 dCi Concept is a preview of a coming new generation of 3.0-liter V6 diesel engines. The new 2,993cc block is derived from the 2.0 dCi engine, with which it shares 25% of its components. The engine develops 195 kW (261 hp) of power and maximum torque of 550 Nm (406 lb ft) at 1,750 rpm with targeted CO2 emissions of less than 200g/km. The common rail fuel injection system uses two rails pressurized at 1,800 bar which supply 7-hole piezo-electric injectors. This configuration supports up to five injections per cycle. “Ultra-fast” ceramic technology glow plugs enable almost instantaneous preheating and cold starting.
