Abstract:
This paper uses the current results of the Basin-wide water resource development scenario assessment of the Council Study of the Mekong River Commission Secretariat (MRCS) to analyse potentials benefits for economic development to meet the ambitious goal of the riparian states of the Lower Mekong Basin (LMB) countries for poverty reduction and, at the same time, analyse the risks of potential trans-boundary trade-off, which will require an appropriate mechanism to be in place. The scenario assessment results present both opportunities and risks associated with different levels of water resource development in the Mekong countries and the implications of the water diplomacy for both the lower and uper mekong basin. All scenarios could be broadly placed into three main categories with different timeframes and assumptions. Scenario M1 – the early development scenario – characterises baseline water resource developments in 2007; Scenario M2 – the medium-term definite future scenario – characterises existing, under-construction, and firmly-committed water related developments in 2020; and Scenario M3 – the long-term planned development scenario – characterises the planned water developments in 2040 in addition to those assigned for 2020 for implementation over the following 2 decades. The main scenarios aggregate combinations of water resource developments enabling the cumulative assessment of environmental, social, and economic effects in the Member Countries. The Scenarios will bring both economic opportunities in terms of benefits from water resource development as well as risks related to biodiversity changes, the environmental damages and losses of livelihoods, and the dependency on the natural resources of the Mekong River. Each of the scenario results presents the trans-boundary trade-off which requires appropriate skills, capacities of the LMB riparian countries, and water diplomacy to discuss and negotiate for the solutions. Finally, this paper provides some suggestions and policy implications that could be possible mechanisms and solutions for sustainable water resource development in the Mekong region.

2. Energy Reality and Emissions in ASEAN: Energy Modelling Scenarios and Policy Implications

Abstract:
The Association of Southeast Asian Nations (ASEAN) faces tremendous challenges regarding the future energy landscape and how the energy transition will embrace a new architecture – including sound policies and technologies to ensure energy access together with affordability, energy security, and energy sustainability. Given the high share of fossil fuels in ASEAN’s current energy mix (oil, coal, and natural gas comprise almost 80%), the clean use of fossil fuels through the deployment of clean technologies is indispensable for decarbonising ASEAN’s emissions. The future energy landscape of ASEAN will rely on today’s actions, policies, and investments to change the fossil fuel-based energy system towards a cleaner energy system, but any decisions and energy policy measures to be rolled out during the energy transition need to be weighed against potentially higher energy costs, affordability issues, and energy security risks. This paper employs energy modelling scenarios to seek plausible policy options for ASEAN to achieve more emissions reductions as well as energy savings, and to assess the extent to which the composition of the energy mix will be changed under various energy policy scenarios. The results imply policy recommendations for accelerating the share of renewables, adopting clean technologies and the clean use of fossil fuels, and investing in climate-resilient energy quality infrastructure.

Abstract:
The power generation mix of the Association of Southeast Asian Nations (ASEAN) is dominated by fossil fuels, which accounted for almost 80% in 2017 and are expected to account for 82% in 2050 if the region does not transition to cleaner energy systems. Solar and wind power is the most abundant energy resource but contributes negligibly to the power mix. Scalable electricity production from wind and solar energy faces tremendous challenges due to system integration practices in ASEAN. Investors in solar or wind farms face high risks from electricity curtailment if surplus electricity is not used. Technologies for battery storage (lithium-ion batteries) have been developed to handle surplus electricity production from wind and solar energy but they remain costly. Hydrogen produced from electrolysis using surplus electricity, however, has numerous advantages that complement battery storage, as hydrogen can be stored as liquid gas, which is suitable for many uses and easy to transport. Employing the policy scenario analysis of the energy outlook modelling results, this paper examines the potential scalability of renewable hydrogen production from curtailed electricity in scenarios of high share of variable renewable energy in the power generation mix. The study intensively reviewed potential cost reduction of hydrogen production around the world and its implications for changing the energy landscape. The study found many social and environmental benefits as hydrogen can help increase the share of renewables in decarbonising emissions in ASEAN.
