Standard chargers

If you ever needed another lesson for the benefits of a sustainability, the launch of CLP’s brand new charging station for electric vehicles is a neat reminder.

What does a mobile phone, a netbook, and an electric vehicle have in common?  Each manufacturer has a different connection for re-charging your battery.  CLP’s new EV station to be located in Jordan, Hong Kong, will only support three Japanese brands of the various EV manufacturers, and particularly noticeable by its absence Hong Kong’s own EV the MyCar is also overlooked.

My own experience is no different, my laptop, mobile phone, camera, blackberry and MP3 player each have different chargers and connections. As individual consumers it is difficult to demand a standard, but that is exactly what we do need, a common standard. As production volumes increase, it reduces the cost, and future waste and environmental impact. I’ll be happier when I have few chargers not more.

Water charge increase threatened – China

China is once again suffering with problems in the Water sector, although plentiful in some areas, other areas suffer drought conditions.  Here in Hong Kong it’s relativity cold now, barely 10 deg C outside, as our thoughts turn to hot humid summers, the cost of operating cooling towers and providing domestic water services could escalate if the threatened 24% increase becomes fact.

The above (extracts from the unlink-able South China Morning Post on 17-12-2009) gives an indication that the authorities will try to stave off water shortages, not by small changes, but dramatically increasing the cost of water.

Energy Efficiency
Energy Efficiency project managers will certainly need to be aware, and weigh the possible risk of increased water charges into the financial model and assessment for future projects.  Also operators of systems with Process or Comfort cooling Air conditioning systems that use cooling towers would be advised to look closely at the system design and operation for opportunities to reduce water, and energy consumption before the new charging regime is implemented.

Replacing blocked and damaged fill in cooling tower

In many jurisdictions a separate charge is levied for discharge of sewerage/waste, and it can be expense. Therefore while we are considering projects that provide water conservation benefits, let’s not forget to include the avoided sewerage charge in our financial model.

Hot Water Systems
It could be an appropriate time to review to the hot water system, to identify any existing energy losses or water wastage. How many tonnes of tepid water are discharge directly into to drain everyday while we wait for the hot water to actually reach the tap or process? too many I’d argue. Reducing the waiting time lowers bother energy and water consumption.

Industrial Process
Many industrial facilities often need to heat one product line, and at the same time cool another, this is particular common in the food and beverage industry. Many of these systems uses a different water system, often oversized for heating and one for cooling. However, if we consider the problem from a greening perspective, we could easily combine these systems, adding very little complexity, using heat transfer to drive all or part of the process, and replacing one thou water systems for cooling. Therefore, a smart green design would reduce water, sewerage and energy charges.

More than just energy saving
One key point that is often undersold in the rush for energy saving projects are those extra additional benefits, some might argue intangible benefit. But they are real and often overlooked. Many businesses are recovering from the financial crisis, with capital scarce for facilities upgrades. Energy efficiency projects not only save energy, minimising the use of a resource creates opportunities for generating spare capacity without upfront investment.

For example after an energy efficiency project, a switchboard that was fully loaded now has spare capacity. That newly created spare capacity could be used for any number of purposes, perhaps expansion, new machinery, etc. without investing in a new power supply.

Right-sized, and regularly maintained equipment that is not forced to strain unnecessarily all day long has extended operating life span, and avoids the inconvenience, and capital expense of early replacement.

Energy Efficiency is Not Rocket Science

Hong Kong is a great location, indeed I am fortunate to meet a great number of smart, intelligent people that travel through Hong Kong, this week alone I met a Government Minister, a project developer, and financiers from the energy sector.

Its dark down here

I am equally sure that for all the talk about energy efficiency improvement projects, not many people have actually spent as much time in plant rooms as I. Continue reading

Carbon Reporting with only one catch.

Really the Hong Kong the government is so far behind the curve in environmental matters I am surprised that it is not a serious concern for business, or are they blind to the risk? Instead of leading Asia, we lag behind the so called developing countries, and it is our economy that will suffer. I think nobody would want to try and predict the outcome from the Copenhagen summit but as a Chinese city we can expect some impact.

I have previously reported that the writing is on the wall for voluntarily carbon reporting.  And that prediction is one step closer to reality since the EPA (USA) has grasped the opportunity of the new 2009 presidency and signalling intentions for compulsory carbon reporting for US factories.

Global Carbon
Since Carbon is a global phenomena it does not require a vivid imagine to see where all this could lead.  Let’s assume for a moment that China continues to claim “developing country” status and does not require compulsory carbon reporting for manufacturing facilities. Importing countries, like the USA could demand it. You might think I am stretching the US EPA’s jurisdiction, perhaps, perhaps not. Consider the considerable power wielded by US trade negotiators, and the political pressures recently demonstrated by the “Buy American Only” stimulus package! It seems clear to me that any factories or business exporting to foreign markets will need to report their local carbon emissions.

Indeed it could be argued that the China is already heading in this direction (China wants importers to cover some emission costs) has already laid the groundwork, with Chinese official’s arguing that the cost of Chinese emissions for products exported to US markets are the responsibility of US market. In the future US importers may be required to bare an extra cost, the carbon cost, for emissions within China, but wait China is not the only exporter to the US.  Surely India, Thailand, Vietnam, etc. will have equally valid reasons to claim equal rights?

While US business might be quietly smarting over the idea, extra costs that are never welcomed, another surprise could be around the corner because the distant carbon emitted, and hence its cost, will surely give them further reason for pause.

China Energy Efficiency
If your report card was based on China’s energy efficiency, its one that you’d probably like to hide. The power generation sector is predominately coal based that is well known, lacks modern boilers and the latest controls technology. The risk from the resultant emissions could cause a nasty surprise. How this will play out is unclear, it is really a political trade issue more than a technical Carbon issue, undoubtedly there is an unseen business risk.

Cleaner Factory Production in China

Kelcroft, cleaner production consultant china, factory, cp3What does Cleaner Production mean? All manufacturing operations require energy for operations and or create air pollution.  An independent audit of the energy consumption and processes in a production facility will identify areas for improvement of the energy efficiency.

If the facility owner implements the corrective measures the operating cost will be lower, and environmental impact of the facility will be reduced, so we have cleaner production.  Shameless plug for my firm Kelcroft is a registered consultant for the Hong Kong Cleaner Production Programme called CP3 (refer image).

Need an example to clarify? Right let’s take a look at the injection moulding process. Like many processes the press creates heat energy therefore to cool the machine moulds cooling water is needed. It circulated through the injection moulding machine, and the heat rejected outside the building typically using a cooling tower.  However, often the cooling towers are out of sight (and out of mind) they are not properly designed and not regularly maintained. Therefore the effectiveness of the whole process deteriorates causing excessive energy consumption.

This deterioration process does not occur overnight!  No, it is a slow steady process.  These apparently insignificant efficiency losses combine lowering the cooling capacity of the cooling tower installation until one day the injection moulding machine malfunctions, and the facility manager then replaces the whole cooling tower. An energy auditor familiar with cooling tower operation could identify the fix before a minor problem becomes a catastrophe.
