No gas, no kerosene and now no electricity, too, to cook your daily meal

Sri Lanka is in the throes of multiple economic difficulties. Its increasing dependence on imported energy resources is the crux of the problem. This is nothing new, or unexpected, as shown (See Figure 1.)

At least in the present context, the problem is the lack of necessary foreign exchange to import the coal and other fossil fuels, which, concurrently have increased in price. In spite of promises and protestations on increasing the utilisation of indigenous renewable resources, the actions by various ministries and state institutions point in the opposite direction.

In these circumstances the problems faced by every householder, by the shortage of LPG, the preferred cooking fuel, may be the most urgent to be resolved. While the disruption, which occurred some three months ago, was mostly focused on the safety issues, on the heals of a price hike, the present problem appears to be one of shortages due to the inability to raise the dollars needed for the imports. This problem can only be further exacerbated due to the world energy price escalation, requiring even more dollars for future purchases. Naturally, a further price hike will be on the way, signalled by the huge price increase of both petrol and diesel, hard on the heels of the massive depreciation of the Sri Lankan Rupee. The pacifying words of politicians who do not have any understanding or pays no heed to the dire situation faced by Sri Lanka, is of no value to resolve this situation. On the same count the vociferous protests by the consumers or the opposition politicians, demanding subsidies and other none sustainable actions, are equally useless.

It is time to recognise that the solution lies in our ability to develop sustainable indigenous alternatives which are not buffeted by the global circumstances on which we have no control. The much-quoted saying ” Light a Candle Instead of Cursing the Darkness” is of relevance here.

Fortunately for us in Sri Lanka, we have such options for all our energy needs, if only we have the wisdom and the courage to utilise them, as illustrated in previous articles by the author and others. A more urgent and important need is to find such an alternative to Liquid Petroleum Gas ( LPG) foisted on the unsuspecting householders , with high powered advertising , aided and abetted by the short-sighted and ignorant political leaders, who cannot see beyond their noses.

No doubt LPG is an attractive and convenient cooking fuel. But such benefits come at a cost, and as seen at present, even those who are ready to pay the price cannot access it. This was inevitable due to the mindless dependence on imported LPG, in addition to the other fossil fuels, without any consideration on the means of earning the dollars for paying for same.

Options available

It may be recalled that under similar but less severe circumstances, back in 2012, when the only issue was the peaking of the price of LPG, and not the question of availability, the National Engineering Research and Development Centre (NERDC) came forward with a design for a wood-fired cooking stove and issued licences for its manufacture to several parties. While it caught the attention of some consumers, the market collapsed causing much financial distress to the manufacturers. This was on one hand, due to the then government providing a subsidy to lower the retail price of LPG. This was a very short-sighted move. Thus, consumers could not be weaned from the unsustainable dependence on an imported resource. Perhaps, the more relevant cause may have been the failure to develop, concurrently, a sustainable supply chain for the fuel wood necessary to use with the stoves. Once again while the NERDC was engaged in the introduction of the technical development, there was no one, or no state agency, to grab the opportunity and develop the supply chain of fuel wood which would have yielded many spinoff benefits. But let us hope that lessons have been learned in addressing the current dire situation.

I think the original design by NERDC acceptable only to a limited segment of the householders as its basic design lacked the convenience of use expected by some members of the public. Also the use of wood directly as the fuel has some disadvantages when compared to the alternative offered by LPG, even at a much higher cost.

There has been a silent revolution in the intervening years, but the problem has resurfaced. Some enterprising individuals and companies have addressed the problem unlike our so-called leaders and the experts surrounding them.

These innovators have independently developed several models of cooking stoves that use coconut shell charcoal, which broadly resolves the problems encountered with the early designs of the wood-burning stoves such as smoke and soot, and controllability to match the cooking methods of Sri Lankans.

While the use of coconut shell charcoal for cooking cannot be recommended both due to its high cost (Now about Rs 150.00 per kg in retail markets) on the one hand, and the fact that it is too valuable a resource to be just burned. Coconut shells are the primary raw material for manufacture of Activated Carbon, a major export product earning very valuable foreign exchange, particularly in these difficult times.

Some models of stoves in market

However, the value of the new designs introduced as well as the new upgraded designs of the NERDC stove work equally well with wood charcoal. (Figure 2) Of course, the wood charcoal must be manufactured with sustainable sources of bio mass. Fortunately, Sri Lanka is blessed with such natural resources with short rotation coppicing species such as Gliricidia, IPIL IPIL (leucena leucosephala ) Caliandra, etc., and many species of bamboo, and even some invasive species such as Julie Flora Prosipis (Kalapu Andara) and Diyapara, all of which produce excellent charcoal.

Sri Lanka has not traditionally adopted wood charcoal as a common fuel, perhaps due to hitherto easy access to other forms of biomass, which by and large have not been unsustainable. Furthermore, contrary to common myths used to promote LPG, such practices have not been a cause of any health risks. As such there is no established supply of wood charcoal, unlike coconut shell charcoal.

Price Advantage – The Driver for the Change

But as described above our adoption of this sustainable indigenous resource will help not only resolve the current and future dependence on imported LPG or LNG for that matter, but also overcome any such health risks if present in the more congested urban dwellings. We will forever be free from the vagaries of world market price and supply volatility, and the need for foreign exchange, as well as the ever present fear of price hikes locally. The chart below illustrates the comparative costs of the usage of different fuel options, which is the main driver for this change. (See Table 1)

It is important to note that the option of using fuelwood directly is still open to those who have well ventilated kitchens, particularly with the advent of the ANAGI LIPA to replace the traditional three-stone hearth, with a three-fold increase in efficiency and thereby the wood consumption. The value of this most effective and very low cost innovation cannot be overstated for those who can have the ready access to the fuelwood, perhaps from their own homestead at absolutely no cost.

Barrier to Overcome

The major barrier which prevented the initiation of this change in 2012 will remain if reliable and convenient access to the fuel resource such as wood charcoal in the present context is not developed speedily.

Sri Lankans must learn not to expect anything sensible to be done by the State. The two synergic opportunities of manufacture and marketing of well-designed and constructed charcoal burning stoves, some models of which are already in the market and the business of charcoal manufacture, distribution and sales, are well within the means of individuals or SMEs, without any significant initial capital.

The least the state agencies should do is to create public awareness so as to attract more users to both segments of manufacture of stoves and the establishment of the sustainable supply chain. The mandate of the Sustainable Energy Authority is clear on their responsibility in this regard.

The Way Forward

While the NERDC will support the manufacturers of stoves with technical assistance, the Bio Energy Association of Sri Lanka is willing to share the simple technologies and business plans for the manufacture of wood charcoal at any scale of engagement.

Both ventures, feasible at small and medium scale is a good example of the concept of “Prosumers”, wherein the consumers themselves can contribute to the development of the energy resource, similar to the rooftop solar systems currently in high demand and can easily be expanded greatly in the short term to help contain the power crisis.

Moreover, Sri Lanka would gain the advantage of achieving the highly desirable status of none dependence on external sources to serve this vital segment of energy services and regain a modicum of the national pride, which is in tatters at the moment, instead of going round the world begging.

Are cracks already showing ?

Published

on

I thank Dr P. A. Samaraweera for giving me the opportunity to explain further why I think the new government is not different from previous regimes. It seems to be better in some respects, in the short term, which is the norm for new regimes, but most seem at best cosmetic. In his opinion piece “Cracks are showing already – a response” (The Island, 8 November), in response to my piece in The Island of 1st November, Dr Samaraweera says, “UW has not offered an alternative. Is he of the opinion that the SJB, the SLPP or Ranil’s crowd would do better?” I do hope the new regime will succeed but with the proviso that it should take constructive criticism and make course corrections. It is not for me to suggest alternatives but comment when things go wrong. In fact, I was among the first to criticise Pohottuwa when things started going wrong, posing the question “Pohottuwa: Will it blossom or wither?”

Though Dr Samaraweera states mammoth crowds are attending NPP meetings, I have seen a number of reports that voter apathy has already set in and groups who helped AKD to win the presidency seem already disenchanted. This is well stated in the editorial, “Tuk-tuk tut-tutting and ground reality” (The Island, 4 November):

‘Many are those who are tut-tutting over the latest fuel price revision, which has not brought any relief to the general public; trishaw drivers, who served as the JVP-led NPP’s grassroots propaganda foot soldiers, as it were, are prominent among them. Quite a few of them are openly critical of the NPP government.’

Corruption comes in many forms, financial corruption being the most talked about in relation to politics. The NPP does not seem to be guilty of this type of corruption yet and seems to be chasing after politicians guilty of this but at the moment it seems to concentrate on illegal vehicles! But it is certainly guilty of the other type of corruption; ‘jobs for cronies’ and the probable protection of those who have question marks raised against them, as well demonstrated by the Ravi Seneviratne-Shani Abeysekara affair!

Ranil appointed two committees on the Easter Sunday bombing towards the end of his term and some have justifiably questioned his motives but these should have been done at the time of the appointment. Udaya Gammanpila has done the right thing by making the committee findings public, a duty that should have been performed by the President who was elected on the promises of transparency and honesty. As mentioned in my previous article, when he was questioned about these at the ceremony presided over by Cardinal Ranjith in the Katuwapitiya Church on 06 October, the President’s evasive answer gave the impression that he had not read the reports but now it transpired otherwise.

Had the new government, which demanded the release of those reports while in Opposition, decided that it did not agree with the findings and decided to ditch the recommendations, it should have done so, before the expose by Gammanpila. Instead, there were implied threats to Gammanpila! Then followed the vilification of him on social media. Worse still were the accusations made against Justice Janaki de Alwis. Gammanpila’s challenge to justify those accusations has been ignored by the government.

The other report from the committee, headed by Justice S. A. Imam, the findings of which were released by Gammanpila, after I wrote my last piece, exposed unverifiability of the UK Channel 4’s claims. No reasons have been given by the government or Cardinal Ranjith, who has now admitted that he was in possession of both reports, for rejecting this report. Is it that they have already decided who the mastermind is and will appoint yet another committee to support their view?

Another interesting question is whether Cardinal Ranjith has let down the Catholic community by his actions. Perhaps, it is best left for that community to decide.

As the De Alwis Committee recommended taking legal action against both Ravi Seneviratne and Shani Abeysekara, can they be a part of a future investigation into the Easter Sunday attacks, even if the government has decided to discard the report. When there is an element of doubt, in a crucial investigation of this nature, should they be allowed to continue in positions where they could influence the outcome? They should have stepped aside till their names were cleared.

Need for alternative fuel source   

Published

Kantale Sugar Factory

The Middle East conflict is raging. There are reports of one merchant ship being set on fire. If it escalates further, Sri Lanka’s economy will suffer.The cost of fuel amounts to nearly 30% of Sri Lanka’s total imports. There are also fears that the availability of petroleum-based fuels will be over in the world soon.

It is high time Sri Lanka reduced its independence on imported fuel.

Only China is said to be seeking self-sufficiency in fuel viz the production of Butyl alcohol (Butanol). They are said to target 100 million tons to be produced in the near future. Hydrogen is a by-product of producing Butyl alcohol.

It is used to generate electricity through fuel cells. China is said to manufacture about 10% of the fuel cells in the market. The fuel cells were expensive as the critical unit was made out of platinum. A few years ago, the Cambridge University developed a catalyst based on steel to replace the platinum.

Production of butanol, as in the case with ethanol – the alcohol drink- is based on sugar, starch and cellulose.

The raw materials used for producing butanol is corn and in Brazil it is sugar cane. These are two crops that are very expensive to grow and maintain because the plant last only a year and has to be replanted annually.

There are plants available in Sri Lanka, which will last at least 25-30 years once planted, could yield about 1.5 times that of sugar cane. These crops will bear the yield in about 2.5 years after planting. There are also plants that last about 90 years

The only land mass where such plant crops could be grown in one unit is the denuded sugar cane lands at Kantale Sugar Factory. The public should be encouraged to plant sugar cane. They will gain economically from not only planting sugar cane but also from employment opportunities at sugar cane processing centres. My estimation is that about three or four million new jobs can be created as this industry is labour intensive.

Butanol distilleries are not massive structures like the distilleries at Pelwatte, Sevenagala or the old Kantale. Some Universities in the US report regularly on their work on the production of Butyl alcohol. According to the information emanating from those universities, the production facilities are slim and compact.

The technology for the production of Butyl alcohol is not found in Sri Lanka. It is best to seek the assistance of China in this regard.

Butyl alcohol distilleries are said to require four rectifying columns according to technology used in China and this fact is confirmed by a research article published in New Zealand.

There is the possibility of reducing the number of rectifying columns to two.

I have studied numerous research papers on Butyl alcohol production as I have been in the field of alcohol distillation and blending trade for a long time since 1968.

It is necessary to seek external assistance to design and build the distilleries, and it will be necessary to require the assistance of our universities to develop the processing technology to grow and process the plant materials to be used as raw material- mainly Agriculture, Plant Sciences (Botany), Chemical Sciences (Chemistry) and instrumentation. Assistance of the chemical engineering sector can be sought. This would be a profitable exposure to the students therein.

The cost of the studies to be conducted may not exceed Rs 30-40 million.

There is a fabrication factor at Wadduwa- Paiyagala, serving the existing distilleries. Work there is handled manually. Importing the stainless steel and copper pipes and machines to make flanges will help boost production.

The abandoned distillery at Kantale can be used to handle the raw materials in the central and northern parts of the country and many smaller distilleries will be needed in the other parts of the country.

There are state-owned distilleries at Pelwatte and Sevenagala and jointly owned distillery at Hingurana. These distilleries produce ethanol.

It is possible to use the ethanol produced at these distilleries as fuel for diesel-based vehicles after mixing it with additives to enhance its ignitability. A drawback will be the sheer amount of ethanol needed. A better solution is to convert these distilleries to produce Butyl alcohol. The conversion should not be very costly.  The government should consider this option earnestly.

Sri Lanka’s missed opportunities

Tourist Air Traffic in the Maldives and Sri Lanka as indicated by ‘Flight Radar 24’

As the saying goes, ‘A picture is worth a thousand words.’ The above screenshot was captured on the Flightradar24 flight-tracking app at 0808 hrs on Thursday, November 7, 2024. It shows the number of flight arrivals and departures to/from the Maldives compared to Sri Lanka. The large number of small aircraft are island-hopping floatplanes conveying tourists between the Maldivian capital and the country’s many resort islands.

after all these years, Sri Lanka has still not got its act together with regard to airport usage, falling behind even small countries such as the Maldives.

In Sri Lanka, despite the ‘boast’ of as many as 16 airports, of which five are international gateways, and numerous water-landing sites, domestic aviation is all but dead, especially as an adjunct to Sri Lankan tourist infrastructure. According to a recent OPA (Organisation of Professional Associations) report on domestic aviation in Sri Lanka, the Civil Aviation Authority-Sri Lanka (CAASL) is more ‘obstructive than facilitative’.

Private aviation operators report, with reference to various approvals, that what takes the Maldivian Civil Aviation Authority two days to accomplish takes “a month of Sundays” in CAASL.

The volume of air traffic in the Maldives is so high, a new runway has been constructed and activated at the refurbished Malé-Velana International Airport on Hulhulé island, relegating the pre-existing runway to the status of a parallel taxiway. This obviates the need for aircraft landing on the new runway to backtrack along it to reach the terminal, in turn holding up other aircraft from landing and taking off. A ‘luxury’ that even Mattala Rajapaksa International Airport (MRIA) does not have in place.

Result: a smooth and increased flow of arrivals and departures, with use of the new taxiway (i.e. old runway) ensuring the new runway is available at all times for what it was intended.

But over in Sri Lanka, where are our movers and shakers of aviation tourism? What are they doing to improve aircraft movements at our major international airport? Equally importantly, what are they doing to increase the use of aviation to enhance Sri Lanka’s tourism potential? Are they asleep? Or sitting on their collective hands? Has Sri Lanka missed the (Air)bus?

What a sorry state of affairs!
