The preservation of these rainforests is paramount not only for safeguarding biodiversity but also for ensuring the long-term well-being of all living beings.

Singapore’s Clean Energy Challenge: Importing from ASEAN Neighbors and the Hydrogen Quandary

Singapore’s National Hydrogen Strategy calls for low-carbon hydrogen usage as a “major decarbonization pathway” to help it reach its emissions goal of net zero carbon by 2050. The city-state faces a significant challenge in its quest for clean energy, particularly with its heavy reliance on hydrogen production. However, a heated debate surrounds the type of hydrogen Singapore should focus on: blue or green.

Hydrogen Dilemma: Blue vs. Green

Natural gas constitutes approximately 95% of Singapore’s electricity generation, while renewable sources account for less than 3%. Once considered a clean fuel, natural gas emits roughly half the carbon dioxide of coal per unit of energy, contributing significantly to greenhouse gas emissions. Additionally, the gas industry’s methane leakage exacerbates its climate impact, as methane is over 25 times more potent than carbon dioxide in trapping heat. Beyond climate concerns, the combustion of natural gas also produces harmful pollutants that pose health risks.

Recognizing these issues, Singapore developed its National Hydrogen Strategy in 2022 to reduce its dependence on natural gas. The strategy aims to incorporate low-carbon hydrogen as a major element in achieving net-zero emissions by 2050. However, the plan is ambiguous about whether it prioritizes blue or green hydrogen. Green hydrogen, produced using renewable energy, emits no carbon dioxide, while blue hydrogen, derived from fossil fuels (mainly natural gas), still results in significant emissions.

Carbon Capture and Storage (CCS) Concerns

To mitigate the emissions from blue hydrogen production, Singapore is considering carbon capture and storage (CCS) technology. However, CCS has faced criticism for being energy-intensive, costly, and often failing to meet emissions reduction targets. Additionally, there are concerns about the long-term reliability of storing carbon dioxide underground, as leaks can occur over time. Given these drawbacks, Singapore would benefit more from focusing on green hydrogen, despite its current cost prohibitions.

Green Hydrogen Challenges

Green hydrogen is a long-term solution that remains expensive. The levelized cost of green hydrogen production ranges from $3-6 per kilogram, factoring in the costs of electrolysers, renewable energy procurement, and electricity grid connection. Singapore’s limited land mass (709 square kilometers), low wind speeds, and high urban density further constrain its ability to produce green hydrogen domestically. Additionally, the city-state lacks significant river resources for hydropower, and other innovative energy sources like wave and tide energy are impractical due to existing port infrastructure and low tide spans.

Regional Clean Energy Cooperation

Given these constraints, Singapore must look towards importing clean energy from its ASEAN neighbors. Initial steps are being taken to establish energy supply deals within the region. For instance, Sembcorp Utilities, a unit of Singapore’s Sembcorp, and PetroVietnam Technical Services Corporation agreed in August to explore the development of offshore wind farms in Vietnam, aimed at exporting power to Singapore. This collaboration could see the first stage involving power from a wind project off the coast of southern Vietnam.

Similarly, Indonesia presents a promising source of clean energy. In September, Singapore’s Energy Market Authority granted conditional approvals to five companies to import 2 gigawatts of low-carbon electricity from Indonesia. These approvals are the preliminary steps towards obtaining the necessary licenses and permits for project execution. The projects under consideration include a solar power plant and manufacturing plants for battery energy storage systems, with operations potentially starting as early as 2027.

Benefits of Regional Clean Energy Imports

Importing clean energy from neighboring ASEAN countries can significantly aid Singapore in meeting its decarbonization goals. It would also provide renewable energy exporting countries with the incentive and financial support to further develop their renewable energy sectors. This regional cooperation could help shift the broader energy landscape in Southeast Asia, which is still heavily reliant on coal and gas-fired power generation, towards cleaner energy sources. Such a transition would be mutually beneficial, helping Singapore manage its energy supply challenges while promoting a more sustainable energy future for the entire region.

In Short

Singapore’s ambitious National Hydrogen Strategy underscores the city’s commitment to achieving net-zero emissions by 2050. However, the journey is complex, involving a critical decision between blue and green hydrogen. While blue hydrogen poses significant environmental and technological challenges, green hydrogen, although costly and currently unfeasible for domestic production, offers a more sustainable long-term solution. The city’s limited renewable energy resources necessitate reliance on regional clean energy imports, fostering collaboration with ASEAN neighbors like Vietnam and Indonesia. This strategy not only aids Singapore’s decarbonization efforts but also catalyzes a regional shift towards cleaner energy, showcasing a pathway to a more sustainable and interconnected energy future.
