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.

Canadian High Commissioner Isabelle Martin shaking hands with Minister Abayaratne

Canada, said to be the home to the largest Tamil Diaspora community, has expressed concern over the delay in holding Provincial Council (PC) elections. Canadian High Commissioner Isabelle Martin, on Monday (16), took up the issue with Public Administration, Provincial Councils and Local Government Minister Professor Chandana Abayaratne.

Sources quoted Prof. Abayaratne as having told the Canadian HC that the delay was not deliberate on the part of the government. The Minister blamed, what the sources called, certain legal, technical and delimitation issues for the delay.

India compelled Sri Lanka to enact the 13th Amendment to the country’s Constitution to enable the setting up of the Provincial Council system, in line with the Indo-Lanka Peace Accord, which Sri Lanka signed under duress in July 1987.

Prof. Abayaratne has assured the Canadian HC that President Anura Kumara Dissanayake, too, recognised the importance of strengthening the Provincial Council system as a solution to ethnic issues and that urgent steps would be taken in that regard.

During the discussion, matters relating to strengthening political, economic and social relations between the two countries were discussed.

In May 2020, Canada declared that Sri Lanka had perpetrated genocide during the war against the LTTE. Canada also sanctioned former Presidents Mahinda Rajapaksa and Gotabaya Rajapaksa in January 2023 over alleged war crimes.

The Canadian HC also explained her country’s ‘Indo-Pacific’ strategy and how Sri Lanka could benefit from it.

In particular, Canada’s “Pathways to Peace” project will support reconciliation between nations, and to improve communication by encouraging the learning of mutual languages as a second language, and it was also agreed to provide more opportunities for Sri Lankan students to pursue higher studies in Canada.

The Canadian delegation also expressed its willingness to provide the necessary technical assistance to solve the drinking water problems in Puttalam, Mannar and the North-Eastern provinces under technical cooperation, and to implement the relevant projects after a preliminary study.

Sajith with David Lammy at Opposition Leader's Office, in Colombo

SJB and Opposition Leader Sajith Premadasa has briefed Deputy PM of the UK, David Lammy, on the dangers posed by the proposed Protection of the State from Terrorism Act (PSTA) and the Online Safety Act.

They met at the Office of the Leader of the Opposition, in Colombo, on Tuesday (17). Discussions focused on democratic governance, trade expansion, and bilateral humanitarian cooperation.

The British delegation included High Commissioner for Sri Lanka Andrew Patrick.

Head of the Deputy Prime Minister’s International Unit David Meyer, Special Advisor Ms. Fiona Meagher, and First Secretary (Political) Tom Soper,

According to a statement issued by the Opposition Leader’s Office, Premadasa has cautioned against what he called draconian applications of the law, specifically warning against broad definitions of terrorism that could criminalize political dissent and trade union activities. Premadasa reiterated that the judiciary, not the executive, must drive legal interpretations. Regarding online safety, while acknowledging the need to protect children, he stressed that regulations must align with UK standards and international norms without infringing on civil liberties.

The Opposition Leader welcomed the UK’s leadership as the President of the Group of States against Corruption (GRECO) and its global Anti-Kleptocracy Campaign. The SJBer highlighted the critical need for transparent institutions, noting that strengthening accountability mechanisms is central to rebuilding public trust and ensuring sustainable economic recovery in Sri Lanka.

Premadasa conveyed sincere appreciation for the UK’s “Sovereign Solidarity” following the devastation caused by Cyclone Ditwah in late 2025. He thanked the UK government for increasing its humanitarian aid package to £1 million (approx. $1.32 million) in December 2025. This funding, channelled through the Red Cross, UNOPS, and local partners, has provided: Emergency shelter and repairs for damaged homes; Clean water and sanitation facilities to prevent disease; and essential medicines and food supplies for the 1.8 million people affected.

Premadasa also proposed enhanced cooperation in protecting Sri Lanka’s wild elephant population and addressing the growing human–elephant conflict. He emphasised the need for sustainable conservation strategies, scientific land-use planning, community protection measures, and international technical support to safeguard biodiversity while ensuring the safety and livelihoods of rural communities affected by human–elephant interactions.
