Where does all that waste come from? If it's local authority waste - which it sounds like - then they have to tender for its disposal and it is likely to go to Energy from Waste plants? Without the waste, no project It looks a bit theoretical, was first announced in 2010, with operation in 2014... Let's see the waste, then we can move it from the PR for aeroplane industry tray to the real tray
Where does that waste come from? I have not seen a tender.... Is this project real?
This is possible but not a good idea. Methane is a perfect vehicle fuel, CNG or LNG Conveying it to a liquid is a waste of energy,,..it's like going from LA to New York by travelling west. Possible but why would you do it? Why melt down gold to make tin?
There are methane leaks in gas distribution networks that are reducing slowly as old cast iron mains are replaced with plastic. But these are fixed, same for any throughput. So additional gas demand does not add any more leaks. Shale gas is a very good source of gas as there are minimal leaks - for obvious reasons, the gas is valuable and the nature of the process means there are no opportunities for leaks We are entering a Golden Age for gas and if we can have CCS - Coal Can Stayunderground in China and India we have a chance of saving the planet. Europe must stop its mad dash for coal generation and follow the US with great investment in gas, wind and solar.
Davemart The CNG tanks are on the CNG car, as VW Eco Up! at 79 g/km. Gas is taken directly from the grid and into the vehicle, no storage at the home. The Eco Up! has been given the award of Germany's most environmentally friendly car. The Verkehrsclub Deutschland (VCD) — Transport Association Germany — awarded five stars and overall first place for 2012/2013 to the VW eco up! With home fill needs a compressor to run approx 30 hours per week for annual miles of 15,000 - to save co2 it is best to select the 30 hours at times of high renewable elec production and low elec demand. Solar also a great source. Of course can also run on fossil generated electricity but that should just be back-up. The VW Up! also runs on petrol, range around 500 miles Because of the existing gas grid, if you do the full well to wheels of CNG home fill using wind for electricity and highly economical VW Up! it is much lower than using gas to make h2 for fuelling a car. H2 is very good to use surplus electricity but it is very inefficient if made from NG as the conversion process is far too wasteful in energy terms Of course the idea is to make Biomethane, inject it into the gas grid and take it out at the home fill device. More than 200 CNG stations in Germany now offer this, very low carbon, very efficient It is incredibly exciting to see cars such as the Up! I have waited 15 years for cars to be designed specifically for CNG and we now have them and they are fantastic. The old range issue with CNG has completely gone away due to the efficiency strides which means a large CNG tank is not required. We are entering a Golden Age for gas and it is a fantastic opportunity for the planet, to reduce global warming, displace coal and oil and support renewables.
Electric Vehicles have had their time in the sun, they had a good run. Who Killed The Electric car? Why the small diesel and petrol hybrid did. The energy efficiency of new internal combustion engines is very good and coupled with hybridisation, there is no space for EVs. What will win in the end? The CNG hybrid of course, filled at night with gas at home using home fill compressors that chug away overnight on the days of the week that the wind is blowing. Only fill up 2 x a week so just do it on windy nights. So, utlises the wind for compression that could have charged EV batteries but in a way that allows complete 100% displacement of diesel/petrol as no range issue anymore on CNG (as they hardly use any fuel) The fact that UK has >200 years worth of gas under Lancashire etc helps as well. Sorry Qatar, sorry Saudi Arabia, sell your fuel to someone else please. I cant wait for the US home fill devices that are being funded by Obama (you got to admire the US Govt – they funded the shale gas technology breakthrough and are now funding home fill CNG. We would call it joined up thinking) We are in a Golden Age for natural gas and I haven't even mentioned biomethane which is what we work in!
Converting methane to liquid fuels is possible but why would you do it? Its like going from Los Angeles to New York by travelling west, possible but pointless. Far better to use the methane for all transportation in CNG/LNG vehicles..if you do this, there is no shortage of oil for chemicals and other things where oil is needed. By 2030 most vehicles should and will run on natural gas, thanks to shale gas
Gas fuelled vehicles starting to be sold in significant numbers, over 110,000 in Italy in July, 11 per cent of new vehicle sales.... http://www.ngvglobal.com/fiat-natural-gas-vehicle-sales-strong-while-auto-market-declines-in-italy-0925#more-23198 So it is possible to move from petrol and diesel to gas, in due course changing methane to hydrogen may be viable.....if its not, then as long as the methane made from waste via digestion or gasification or from H2 to CH4 processes, then we have pathway to carbon free transport
There are no adverse issues with fracking....the US coal industry is trying to find things wrong with it but there is nothing and this is becoming clear Sorry coal industry, you are finished Natural gas as vehicle fuel gives very high overall well to wheel efficiency, much higher than using gas to make hydrogen
In UK there is leakage out of low pressure gas pipelines. These were built pre 1960 and around 0.5% of the methane leaks out. The grid is progressivly being replaced with new plastic pipes. However, the leakage is not related to throughput. So adding CNG vehicles does not increase the leakage. In practice, CNG stations are usually fed from higher pressure grids that are newer, steel, do not leak at all....so what this study is saying is that there should be investment in replacing leaking pipelines in the domestic heating market. No argument with that, but this has nothing to do with CNG for vehicles which reduces CO2 with NO increase in leaks of methane.
Natural gas (CNG or LNG) as a fuel for trucks is not even on this list and is the best idea!
Meanwhile, Pike Research expects that remote sensing will be the breakout market for small fuel cells in 2012, as they are well-suited for applications including dam monitoring, seismic monitoring, wildlife monitoring, weather stations, and others Has it come to this? The fuel cell is well suited to Wildlife monitoring? Probably a good application....clearly hydrogen fuel cells RIP as a way of helping provide energy for cars..... By the way, what happened to the Honda FCX - this article from 2005 - 7 years later? http://www.greencarcongress.com/hsub2sub/index.html Maybe the Honda FCX can be used as a weather station and to monitor wildlife?
This is a great way to increase demand for coal and natural gas to make the extra electricity.
GTL starts off as natural gas. So the comparison should be with exporting LNG and using LNG in dual fuel LNG-diesel trucks or making CNG and using in the Passat Ecofuel. If you do that, the GTL pathway is around 30% worse in CO2 terms. GTL is like going from Los Angeles to New York by going west. You can do it, but its not the best idea.
But thankfully hardly anyone is buying electric cars because they do nothing to reduce CO2 compared to using the £5,000 subsidy for something that does reduce CO2 - like insulating homes........in UK, EV's are not as low CO2 as a low emission diesel or petrol hybrid because all the extra electricity to charge them comes from gas and coal...
EU MARGINAL elec generation is much higher because it is gas or coal, at least twice as high as 235 kg CO2 per MWh EVs in EU make no sense because of the growing dependence on gas and, in Germany, coal.
This is ruining it for coal fired EVs like the Leaf. What is the point of an EV ??
With 900 CNG filling stations in Germany, makes much more sense to run vehicles directly on natural gas if they are designed for gas (smaller engine, turbo, supercharger, low CO2) http://www.ngvaeurope.eu/european-ngv-statistics The NGVs like the Passat Ecofuel can also run on petrol if they are going in an area with no CNG. There is no point in H2 vehicles unless there is a surplus of nuclear/renewables and there clearly is not going to be that in Germany for a very long time.
LNG is useful for long trips but CNG ideals for depot based back to base trips, Can get 500km range on CNG in 4 x 2 tractor which is enough. Also, biomethane injected into the gas grid at the Anaerobic Digester plant and taken out at the distribution depot as CNG is perfect.
From Jan 2010 According to Pike Research, which is a marketing and consulting firm in the green tech field that offers in-depth analysis on a wide variety of alternative energy subjects, there will be 2.8 million fuel cell vehicles on the roads by the year 2020. So their forecast has fallen from 2.8 million to 1 million in the last 15 months. Maybe next year it will be 10,000 which will be more accurate!
Methodology is not correct. The EV uses marginal electricity (coal or gas) and not grid average. So the CO2 level is a lot higher than this. UK minimum electricity demand is 24 GW. Max zero CO2 (wind, hydro, biomass, nuclear) is around 14 GW. So the extra electricity always comes from coal and gas. This is much higher than the average.
what a great idea...we need these in London
Looks like H2 as a vehicle fuel is well into the long grass.....with natural gas starting to take over from coal for making electricity due to the shale gas resource, it will never make sense to use gas to make H2 for a vehicle or to use gas to make electricity to make H2. It will always be better in CO2 and cost terms to just use the natural gas and avoid the expensive (in cost and CO2) conversion step. Good to see GM launching CNG vans.....there is a huge growth in CNG the world over....
What is the weight of the EV? Clearly CNG vans have a slight disadvantage in weight terms compared to diesel, they make up for it in having lower emissons of NOX, particulates etc and CO2 neutral on biomethane. My question was about the concept EV. My theory is its the weight and therefore efficiency point that means that there are no plans to build it. Can anyone find out the weight comparison with a diesel and CNG van?
