Laurence Kwan is Sunseap Group’s subject matter expert in the areas of electricity and electricity transactions in Singapore and Asia Pacific. He has amassed years of managerial experience in a variety of corporate sectors across a wide industry spectrum. He is also a strong advocate for renewable energy.


1. I understand that Sunseap has had over 30 years of experience in providing clean energy solutions in Singapore. What are the company’s proudest achievements so far?

One of our proudest achievements came in the form of a landmark agreement with Apple to supply 100% of its Singapore operations with 100% renewable energy via our portfolio of solar energy systems. It was the first 100% renewable energy agreement in South East Asia, and we were very proud to be associated with big brand name such as “Apple”

Our most recent achievement came in September ’17 via Banpu Public Company Limited’s SGD$75million investment into our company.

2. You’ve only recently joined Sunseap, how far do you see the growth of your company and solar energy in Singapore and in the region?

There is immense potential and room for the development of solar energy in Singapore and the region. Recently, the Deputy Prime Minster of Singapore mentioned the potential to have a peak of 2 GigaWatt-peak of solar energy by the year 2025. Apart from traditional setups via rooftops and ground mounted solar installations, Sunseap is also looking at floating solar energy systems to maximize the deployment of solar energy systems in Singapore.

Outside of Singapore, solar energy can benefit countries where there is a lack of electrification, particularly rural areas such as regions in Cambodia and Myanmar. Solar can be deployed at a much faster pace as compared to traditional power grids which takes years to develop, thereby having a greater potential to solve the rural electrification problem more readily.

3. Tell us more about Sunseap’s venture into Cambodia as the nation’s first solar project. How big is this project? What goals has the company set for the project?

Our solar farm in Bavet City, Cambodia is approximately 10 MegaWatt-peak (MWp).  The solar farm serves the villages in Bavet City and helps to reduce the village’s reliance on neighboring Vietnam for electricity. The solar farm represents the Cambodian government’s step towards their target to have at least 70% of all Cambodian households to have access to grid electricity by the year 2030.

4. What challenges has Sunseap faced so far in the nascent renewable energy industry? And how are you overcoming them?

It is challenging to convince consumers of the importance and impact of using clean energy. Education is required to convey the benefits of clean energy and effects of global warming to the general public. We also found it challenging at times to explain our zero-cost clean energy solution to potential clients as many of them are not familiar with such models.

In order to provide zero-cost solutions for our clients, we also require a constant injection of large capital to fund our solar energy systems. Outside of Singapore, government regulations have proved to be most challenging with each country having its own set of rules and regulations.

5. How far or how soon do you think that renewable energy industry will replace fossil fuels as the main energy source to power the economies in this region?

I think we are still a couple of decades away from renewable energy surpassing fossil fuels as the main source of energy. For that vision to become a reality, the prices of the various renewable energy sources, as well as energy storage solutions must improve to the point where it makes economic sense for businesses to take up. Governments must make a stronger push to advocate the benefits and importance of renewable energy.

Energy storage solutions is a crucial component of this process as it will allow owners of the renewable energy generation assets to store the energy generated for later use, reducing cost over the long run.

6. You’ve been in the energy industry for some time now, and you’re considered a subject matter expert in the areas of electricity in Singapore & Asia Pacific. How did you get into this role?

It has been a long hard-fought journey since. Being true to our values and sincere to our calling to bring renewable energy to the wider masses, we have and will continue to work hard to develop better products and services in Singapore and Asia Pacific.

We also work closely with various government agencies to ensure Sunseap is constantly growing and learning together in all the countries that we plant our businesses in.

7. How has your professional network been important in getting you where you are today? Are you in favor of the idea of advancing your professional network through social media or networking platforms?

It is very important to enhance touchpoints. Professional networking platforms are very essential in sustaining the business. For this purpose, Sunseap’s MarComms team is always fanning out suitable platforms.

8. What makes Sunseap different compared to all other solar energy based companies in Asia? 

Our integrated zero-cost solutions ensures the simplest way for our clients to adopt clean energy. We take care of areas such as project financing, installation and maintenance so that our clients can enjoy clean energy at a competitive rate. Our market share and proven track record also differentiates us from the other companies in the solar industry.

Our industry leading practices in our processes also sets us apart. For example, our Renewable Energy Certificates (RECs) goes through a stringent audit (by the Solar Energy Research Institute of Singapore) and verification process (by APX) by independent third parties to ensure accountability and transparency.

9. Other than in Singapore and Cambodia, where else have you seen the biggest growth in demand for solar energy, especially in South East Asia?

Countries like India and Thailand are leading the way in the solar energy movement. Setting targets respectively for 100 GigaWatts of solar power by the year 2022, and 40 percent of the country’s energy via renewable sources by 2036.

10. In this day and age, new technologies are emerging faster than ever before. How is technology reshaping the work that you do?

Advancement in technology has allowed us to reduce production and execution time, and improved the economics of solar panels significantly over the past decade. The advancement of technology allowed Singapore to reach grid parity around the year 2012. Grid parity is the phenomenon where the cost of generating solar energy is less than or equal to the cost of generating conventional energy. Grid parity allowed our business to not only make sense for us, but for our consumers too.

We’ve also embraced big data and analytics throughout our business processes. For example, we employ around the clock monitoring and maintenance with the aid of real-time analytics to maintain our solar energy systems at an optimal performance level. With the aid of technology, we are also looking into the combination of energy efficiency and smart home management systems to help clients reduce their energy consumption and carbon footprint. Going forward, we will also look at ways to improve the aforementioned services with the emergence of artificial intelligence and machine learning.

11. What is the company culture like in Sunseap Group?

We work in an open-office setting, where there is individual offices and no physical barriers. Staff at Sunseap are free to communicate across the various levels of management.

Even though our staff strength has reached approximately 100, our organisational structure still remains one of a flat-hierarchy, where there are only several line managers. By reducing physical barriers and channels of communication, we can advocate a culture of open communication.

12. As Sunseap expands its business locally and in the region, you will be planning to increase your workforce. What type of skills or qualifications are you looking at from new graduate hires?

Always on the lookout for an all-rounder. Candidates must possess basic engineering or finance degree from an accredited university, and having prior work experience or having done a successful internship in the energy sector will be most preferred.

13. What is the one piece of advice you can give to young professionals who are just embarking their careers in the energy industry?

Be diligent in what he/she does, never stop learning, and always apply what he/she is taught to better hone his/her skillset to become an all-rounder.

How Do You Detect Gas Leaks In Your Home?

Everyone should always be mindful of gas safety. Although natural gas and liquid petroleum gas (LPG) don't immediately represent a hazard of poisoning, they present a significant risk of a fire or explosion. It is crucial to keep yourself safe by being aware of the risks and learning how to spot a gas leak.

Natural gas like practically all other energy sources is harmful if not handled properly. You may protect yourself and your loved ones by following a few basic safety precautions (and understanding what to do if you have a gas leak or have been exposed to one). 

Is Using Natural Gas In The Home Safe?

Natural gas is a reliable, safe power source when handled properly. Although burning natural gas emits some greenhouse gases, it is still a more environmentally friendly option than using other fossil fuels. But natural gas is a combustible substance. A natural gas leak in a home could result in a fire, and breathing it in could poison you with natural gas. It is important to use caution when exposed to natural gas, just as with electricity, gasoline, and other potentially hazardous energy sources.

Is There A Gas Leak In Your Home?

If you suspect a gas leak, you should immediately call the National Gas Emergency Service number. Try to open a few windows to allow for airflow before doing so. Immediately leave the premises if you smell gas in a cellar. Our article will explain what to do in your home to assist you to remain safe in the case of a leak so that you are always ready.

Underground pipes used to carry the gas to buildings might cause external gas leaks. If you're outside a building and you smell gas, there probably is a leak, therefore you should call the National Gas Emergency Service.

Appliances that are broken or improperly installed frequently result in gas leaks in homes. Usually, the pipe entering your appliance is where the leak originates. If you've made sure the appliance is turned off, for example, by turning all the knobs on your stove to the off position, then a problem with the hose is probably to blame for your gas leak.

Any appliances you install must be done so by a qualified Gas Safe registered engineer and are given a regular gas safety check or service to assist reduce the danger of a gas leak brought on by a faulty appliance. Make sure to verify their accreditation on the Gas Safe Register website before work begins.

How To Detect Gas Leaks?
  • Look For The Smell Of Sulphur Or Rotten Eggs

Due to the lack of color and smell in most gases, natural gas companies typically add the chemical mercaptan to give it a specific smell. Your home frequently smells like sulphur or rotting eggs when the smell is present. If you spot this specific smell, it could be wiser to investigate the leak's origin or contact a technician.

  • Be Alert For Any Hissing Or Whistling Sounds

If you hear a whizzing or whistling sound close to your gas line, you may be experiencing a serious gas leak. If the noise is coming from the area where your air conditioner is, it can be coming from a refrigerant line, a faulty valve, or a damaged compressor.

  • Implement A Gas Leak Detector

The best approach to determine whether you have a gas leak is to buy a gas leak detector. You have a variety of gas leak detection options. Sensors and leak detectors come in a wide variety. When shopping online, it's important to buy a detector that can detect several different gases. To keep you and your family safe at home, explore different options for gas leak detectors and sensors.

  • Check The Stove Or The Burner Top.

When a stovetop burner is lit, the flame is often blue. The existence of a gas that is removing oxygen from the atmosphere could be indicated by orange or red flames emerging from your stove burner.

  • Conduct The Soapy Water Test

A spoonful of soap and a glass of water combined to create a concentrated solution. Spray the soap-and-water solution on the area that is thought to be leaking, then look for bubbles to form. It suggests the area is experiencing a gas leak.

How To Fill A Portable Helium Tank

Having a helium tank can be helpful if you often arrange or plan big parties. A portable helium tank may be easily filled, which is a blessing. You can bring it to a shop to refill it or order online from a gas service provider store that offers helium gas tank services. 

Refill Your Portable Helium Tank

Some portable helium tanks cannot be filled again. A single-use tank that is being attempted to be refilled has the potential of bursting, inflicting harm on everyone around. If you have a refillable tank, the first thing to do is call nearby businesses to determine whether they provide refill services. The store where you bought the first tank might be able to provide you with a refill. There are other places you can acquire a portable helium tank refill if the store is closed or if you have relocated.

Find local gas and welding shops, party supply stores, and balloon shops by conducting a web search. If these businesses provide helium tank refilling, they frequently list the service on their website. Call nearby businesses to verify that they can fill the tank and to learn what hours they are open to performing the service. Additionally, this provides a chance to contrast helium pricing.

Once you've located a spot, bring the tank there to be refilled. Make sure to take the tank's balloon inflator attachment off before transporting the tank, replacing it with the steel cap. As you are driving, check to make sure the tank is stable and won't fall or roll.

Refillable Helium Tank vs. Disposable Helium Tank

A reusable helium tank may be less expensive than a refillable one. However, if you host gatherings frequently, a refillable cylinder can be a more economical choice. Refillable tanks are an excellent solution for a single event and are available for rental at several party supply retailers.

If you decide to use a disposable tank, keep in mind that you cannot just throw it away. Be sure to properly dump the tank when you've finished using it. Check with your recycling company to determine if doorstep service is an option. Alternately, look up steel recycling businesses in your neighborhood. When disposing of an inflated portable helium tank, make sure to follow all federal, state, and municipal laws.

Considerations Before Using A Portable Helium Tank

It may take some time to receive a refill, and not all stores are open on weekends and holidays. Thus, before an event, make sure you have enough helium to satisfy your needs. Approximately 0.15 cubic feet of helium should be used for each little 7-inch balloon. The amount of helium needed to fill an 18-inch foil balloon is roughly 0.44 cubic feet, whereas an 11-inch balloon requires roughly 0.5 cubic feet.

It's crucial to use and store your portable helium tank carefully if you plan to buy one. Children should not be let near uninflated balloons or tanks because both are potentially dangerous. Helium can hurt you if it is sprayed into your mouth or face because of the pressure. Use helium outside or in a room with good ventilation. Don't drop or damage the cylinder in any way.

Make sure the space is dry when you store the canister because moisture can cause helium tanks to corrode. Temperatures in the storage area shouldn't get above 120 degrees Fahrenheit.

Layout and Maintenance of Wood Pellet Machine Mould

As the core component, style of the wood pellet mill for sale has a great influence on improving the result and high quality of wood pellet production, lowering power consumption, and also minimizing manufacturing expenses.

At the same time, the timber pellet maker mold and mildew are likewise one of the most conveniently used parts. Consequently, it is very crucial for wood pellets producers to understand the layout and application of ring die, and also to make the appropriate selection, rational usage, and also reliable upkeep of ring die.

The following is a quick evaluation of the style, option, use, and also upkeep of the ring die for a referral.

1, Decision of ring pass away diameter as well as ring pass away efficient pressing size specifications

a, The size and also efficient width of the ring die is the main specifications of the wood pellet device die

According to the global timber pellet equipment parameters and also concern series to figure out the ring die size collection, RICHI mainly has the complying with the collection of timber pellet machines:

MZLH320 Wood Pellet Machine

MZLH350 Wood Pellet Making Machine

MZLH420 Wood Pellet Mill

MZLH520 Wood Pellet Maker

MZLH768 Wood Pellet Press

MZLH858 Wood Pelletizer

According to the proportion of equal practical pushing location as well as an equal power, determine the reliable size of the ring passes away.

b, Decision on the rotational speed of the press roller of the wood pellet device

The rotational speed of the journalism roller is associated with the geometric parameters of the timber pellet equipment itself. According to the information detection of the technical criteria of the global pellet equipment, for the ring pass away pellet equipment with 2 pressing rollers, the direct rate at the internal diameter of the ring die is 6-12m/ s better. This is additionally the distinction between the rate of the sawdust pellet machine as well as the feed pellet machine.

The rate of the roller of the timber pellet equipment directly affects the thickness of the material in the pelletizing chamber and also the time for the material to travel through the die opening, which in turn impacts the outcome of the pellet device as well as the top quality of the pellets. If the line speed is too high, under the exact same output, the ring die produces much fewer bits per change, and also the product in the granulation area is little and also unevenly dispersed, which might cause product mistakes, alternate granulation, loose fragments with different lengths, and a large amount of powder. Can't even powder. A lower ring dies line rate can create pellets as well as can produce better pellets, yet the throughput is relatively low.

c, Determination of the size of journalism roller

Ring Die of Pelletizing Equipment

The standard pelletizing principle for pellet formation is received in the figure listed below. The timber pellets can get rid of the resistance of the material going through the aperture of the ring die through the shared extrusion force between the ring pass away as well as the pressing roller, so as to attain the function of granulation.

Pelletizing Concept

Under the same ring dies, the larger the size of the stress roller, the greater the range of triangular extrusion developed between the ring die and the stress roller, which is more conducive to the extrusion result.

In theory, talking, the diameter of the pressure roller of a solitary roller can be the largest, as well as the extrusion time, and also extrusion impact must be the most effective. However, in the procedure of the wood pellet mill, one of the most force in between the pressing roller and the ring die is transferred between the major shaft, the bearing, and the empty shaft, so the mechanical framework of the single-roller granulator is coarse, so it can just be used on a little experimental granulator. It is tough to be utilized in large-scale pellet mills, and also the double-roller sawdust pellet mill has actually come to be the most pre-owned version in the pellet.

2. Ring pass away product and warmth therapy

Wood pellet maker molds are normally made from carbon steel, alloy steel as well as stainless-steel through forging, reduction, exploration, warmth therapy, and various other processes. The product utilized in the ring pass away and also each handling procedure have a straight influence on its service life, granulation high quality as well as the outcome.

Carbon Steel-- Heat Treated Firmness HRC45-50. The wear resistance and deterioration resistance are reasonably poor and are essentially gotten rid of.

Alloy Steel-- Warmth treated with a firmness above HRC50. The thorough mechanical buildings are high, as well as the usage rate is the highest possible.

Stainless steel-- Great hardness and also toughness, total quenching, as well as good wear, and also rust resistance. But its high price has actually dragged down general use.

3. Ring pass away hole structure, compression proportion

 ring die hole

ring die opening

Typical timber pellet maker molds have straight holes, decompression holes, outer conical openings and also inner conical holes. The major criteria are:

Die opening size, ring pass away density, ring die efficient density, decompression opening size, pass away opening facility range, wall surface thickness between die openings, ring pass away diameter, and ring pass away reliable width.

The compression ratio is the ratio of the effective thickness of the ring passing away to the diameter of the die hole. It is an indicator of the extrusion toughness of wood pellets. The greater the compression ratio, the more powerful the extruded particles. Therefore, the die hole of the ring die is determined according to the different raw materials of wood.

4. Usage and also maintenance of wood pellet maker mold

Right adjustment of the working gap in between the ring pass away and journalism roller is vital to the use of the ring die. Usually talking, the void in between the ring die as well as the pressing roller is between 0.1-0.3 mm.

When the space is too huge, the machine will certainly be obstructed as a result of not enough extrusion force. If the space is also small, it is very easy to damage the ring die and the pressing roller. For the operator, it is needed to have useful operation experience and be able to masterfully pick and change the gap of the ring die roll. The adjustment work needs to be grasped with a long-term granulator production technique.
