Lanka can use municipal solid waste to produce 10 tonnes of hydrogen daily – Engineering expert
By Rathindra Kuruwita
Hydrogen an important clean energy source of the future, Sri Lanka can produce 10 tonnes of it a day from municipal solid waste, Eng. Ruwan Nagahawatte, head of the mechanical engineering sectional committee of the Institution of Engineers Sri Lanka (IESL) said.
Nagahawatte said hydrogen is a clean alternative to methane, also known as natural gas. Hydrogen is the most abundant chemical element, estimated to contribute 75% of the mass of the universe. According to a 2023 McKinsey analysis, hydrogen could contribute to more than 20 percent of annual global emissions reductions by 2050.
As of mid-2023, over 1,000 large-scale hydrogen projects have been announced worldwide, totaling $320 billion in direct investments. In Europe alone, $117 billion has been invested in hydrogen projects so far. According to McKinsey, hydrogen is expected to play a crucial role in achieving decarbonization targets in the region.
Hydrogen can be produced from a variety of resources, such as natural gas, nuclear power, biogas and renewable power like solar and wind. The challenge is harnessing hydrogen as a gas on a large scale to fuel our homes and businesses, he said.
Hydrogen can also be produced through methane that can be generated by solid waste. Western province alone generates 300 tonnes of biodegradable municipal solid waste a day and this can be used to produce 7.2 tonnes of methane per day.
“This in turn can be used to produce two tonnes of hydrogen a day. We are talking about the western province alone. With efficient collection of biodegradable waste, Sri Lanka can produce 10 tonnes of hydrogen a day. Sri Lanka can generate over 3,000 tonnes of hydrogen per annum while providing a solution for municipal solid waste disposal. The project needs an investment of 11 million U.S. dollars but the annual revenue generation is expected to be 4.5 million dollars,” he said.
Eng. Nagahawatte, however, pointed out that there are some engineering challenges in the production of hydrogen. The production of hydrogen needs ultra-pure water, a high-grade water that’s free from impurities like microbes, minerals, and dissolved gases through high levels of purification.
“Generating this water is more difficult than producing hydrogen,” he said.
The Head of the Mechanical Engineering Sectional Committee added that hydrogen also needs to be stored below minus (-) 253 centigrade in insulated tanks to maintain this temperature and minimize evaporation. These temperatures are called cryogenic temperatures, i.e., the temperature at which molecular motion comes as close as theoretically possible to ceasing completely.
Eng. Nagahawatte added that hydrogen must be stored at high pressure (350-700 bars) but the technology is improving and that the cost of capital is decreasing rapidly, making it affordable.
“Despite all challenges, the world is very much enthusiastic about hydrogen. This is because of high value as well as environmental considerations. We can start small. We can actually start producing methane first and sell it to consumers. Methane is natural gas, the only difference between this and what we have in cylinders is that this is not liquefied,” he said.

Buddhist hierarchy demands prison perks for monk convicts
MONETABRIEF– Sri Lanka’s two most senior Buddhist chapters, Malwatte and Asgiriya, demanded special concessions for monks serving prison sentences, following the disrobing of convicted monk Ven. Galagodaatte Gnanasara in line with established procedures.
The chief prelate of the Asgiriya chapter, Most Venerable Warakagoda Sri Gnanarathana, told Prisons Commissioner Senaka Palletenna that Ven. Gnanasara, who is serving a six-year sentence for contempt of court, must be released immediately.
Prison authorities have no power to release or pardon convicts, but Palletenna told the monk in Kandy on Friday that he would convey his request to the relevant government authorities.
“There is no point in talking about this and that… The entire country has been shaken (??????? ) . He must be released,” the Asgiriya chief prelate said.
The Malwatte chief prelate, Most Venerable Thibbatuwawe Sri Siddhartha Sumangala, appeared to accept the court verdict against Ven. Gnanasara, but asked the prisons chief whether a separate section could be established for convicted monks.
Palletenna noted that a special ward for the clergy already existed at Welikada Prison.
At least 63 convicted Buddhist monks are currently incarcerated within Sri Lanka’s criminal justice system.
Meanwhile, a group of 34 Buddhist monks named in a Colombo Fort Magistrate’s Court order to vacate the vicinity of the Presidential Secretariat ended their protest and dispersed after lunch on Friday.The monks are demanding an unconditional pardon for Ven. Gnanasara, who has previously been imprisoned, making him a reconvicted prisoner.

Karannagoda pushed for £24,536 for Yoshitha’s UK training, Court told
Former Navy Commander Admiral Wasantha Karannagoda had, by letter dated May 19, 2014, requested the Secretary to the Ministry of Defence to approve the funds required for former Navy Lieutenant Yoshitha Rajapaksa, son of former President Mahinda Rajapaksa, to attend the Royal Navy Young Officers Course at the Royal Navy Training College in the United Kingdom, the Colombo High Court was told on Thursday (15).
The court was informed that £24,536 in public funds had been spent on the training programme. The details emerged during testimony by a Navy representative appearing on behalf of former Navy Commander Admiral Travis Sinniah before Colombo High Court Judge Udesh Ranatunga, when the money laundering case against Rajapaksa was taken up for hearing.
Responding to questions during cross-examination, the witness explained that payments for Navy officers attending overseas training programmes were generally made in foreign currencies, including US dollars and British pounds.
Meanwhile, Navy Captain Nuwan Thushara Arangala, testifying for the prosecution, told court that Rajapaksa had received a total of Rs. 5,159,626.37 in salaries and allowances during his nine years of service in the Navy.
The court was informed that Rajapaksa had served as a Navy Lieutenant from December 14, 2006, to February 28, 2017, although his service had been suspended on February 28, 2016.
According to the testimony, his monthly gross salary was Rs. 16,390, in addition to allowances for food, uniforms, housing and special duties.
The witness clarified that these allowances did not include payments made for overseas training programmes or participation in sporting events while representing the Navy.
During the proceedings, the prosecution also submitted Rajapaksa’s annual declarations of assets and liabilities for the period from 2009 to 2015.
A National Savings Bank official also testified regarding savings accounts and fixed deposits maintained by Rajapaksa, stating that no withdrawals had been made from the accounts since they were opened.
Rajapaksa is facing charges under the Prevention of Money Laundering Act over his alleged failure to explain the source of nearly Rs. 735 million acquired between August 1, 2012, and August 29, 2013, in Rajagiriya and Bambalapitiya.
The prosecution alleges that funds suspected to have been derived from unlawful activities were deposited in bank accounts and fixed deposits.
The court also heard testimony concerning the appointment of a guardian for Daisy Forrest, the second defendant in the case, and matters relating to the clearance of an imported outside broadcasting (OB) truck associated with CSN television.
Further examination of witnesses was scheduled for October 30, with the court directing 11 prosecution witnesses to appear on that date.
