本分析では、100%という最大限の再生可能エネルギー（以下、再エネ）比率を想定した状況下において、送電線や電源などの電力系統内に揚水式水力、貯水池式一般水力発電、地熱発電、バイオマス発電、家庭用ヒートポンプ式給湯器、系統に接続される電気自動車（EV）の蓄電池、水素製造装置、既存ガス火力発電を改修した水素専焼火力といった電力需給調整に必要な柔軟性 (Flexibility) を供給する能力（以下、柔軟性供給力）がどのように利用されるかを明らかにする。
そのために、系統電力需要量に対応する電源構成において、国内再エネ由来の電源が実質的に100% となるシナリオを含む6つのシナリオ（RE60海外水素、RE100、RE100α、RE90α、RE100β、RE90β）を構築した...
This policy brief aims to answer a critical question: how can policymakers, civil society, and researchers address air pollution, climate change, and socioeconomic equity with inclusive solutions? The brief argues that much of the answer will involve reframing how policymakers, civil society groups, and researchers perceive the interrelationship...
This paper examines the effects of financial incentives, particularly electricity prices, on residential solar photovoltaic system installations. We shed light on the importance of a factor that has been largely overlooked in the literature on the adoption behavior of low-carbon building technologies: the distinction between retrofit and new-build...
This article quantifies the environmental, health, and economic co-benefits from the use of solar electricity and heat generation in the Ger area (a sub-district of traditional residences and private houses) in Ulaanbaatar (UB), Mongolia. The quantification of the featured co-benefits is based on calculating emissions reductions from the...
電力需要・電源設備容量が2018年度実績値又は2030年度エネルギー需給見通し（以下、2030需給見通し）見込値と同量を想定するシナリオに対して、発電コスト検証ワーキンググループ（以下、発電コスト検証WG）が想定する燃料費用及びCO2対策費用を発電ユニットごとに課す条件を与えて、実潮流に基づく電力系統運用（1時間毎の価格シグナルを用いたメリットオーダー方式による広域電力系統運用）をシミュレーションすると、2018年度実績値や2030需給見通し見込値よりも石炭火力の発電電力量が小さくなる代わりに、ガス火力の発電電力量が大きくなることが確認された。
そのため、2030年度までに再稼働できる原発の基数が2030需給見通しの見込値よりも小さくなっても（本分析では...
1. The ASEAN State of Climate Change Report (ASCCR) presented ASEAN’s mitigation goal: i) Achieve net-zero greenhouse
gas (GHG) emissions as early as possible in the latter half of the 21st century; and ii) Cap peak GHG emissions as soon
as possible after 2030 to ensure the net-zero GHG emission goal is met on schedule.
2. However, the updated...
While the Sustainable Development Goals (SDG) are broadly framed with 17 goals, the goals and their targets inherently
connect with each other forming a complex system. Actions supporting one goal may influence progress in other goals,
either positively (synergies) or negatively (trade-offs). Effective managing the synergies and trade-offs is a...
India has an ambitious renewable energy target for the decades ahead. However, the targets are faced with two critical impediments: (1) the lack of an internationally competitive renewable equipment manufacturing industry domestically and (2) the overdependency on external supply sources for equipment and machinery. The chapter finds that, despite...
The Paris Agreement sets the goal to limit the global warming to well below 2 °C and preferably 1.5 °C. The recent IPCC report warned that 1.5 °C-warming may occur much earlier than expected. To meet the 1.5 °C target, global emissions of greenhouse gases (GHGs) should be net zero by 2050 or earlier. Increasing number of countries, local...
The global trade of solar photovoltaic (PV) products substantially contributes to increases in solar power generation and carbon emissions reductions. This paper depicts global PV product trade patterns, explores emissions reduction potential, and evaluates the impeding effect of tariff barriers on global PV product trade and emissions reductions...
