Limonitic nickel ore from Indonesia was reduced at 900°C under NH3 with 0–20 wt% Na2SO4, reaching 82.74% reduction at 15 wt% and 2 h while nickel metallisation stayed near 92%. Transparent carbon accounting for the reduction step gives 0.17…

This study compares electricity generation data from 1985–2024 to explain why Indonesia's renewable transition lags ASEAN peers and OECD nations despite abundant hydro, solar, and geothermal resources. By 2024, renewables reached over 40% i…

This paper empirically assesses whether diverting sugar to ethanol under India's E20 blending mandate independently affects domestic sugar prices, controlling for production, stocks, exports, climate, crude oil and food inflation. Using ARD…

Sugiyama M.

Part 1 of JMIP 2 examines how technology uncertainty affects the robustness of Japan's net-zero pathways. It likely analyzes how variation in technology costs and deployment speeds shapes the resilience of decarbonization scenarios, informi…

First full-scale parallel field comparison of a Net Zero Energy Greenhouse (ZEG) versus a conventional greenhouse under identical conditions for commercial strawberry cultivation in Japan. The ZEG, using a groundwater-source heat pump, doub…

Koji Sakai, Takeju Matsuka

This paper presents carbon reduction pathways for concrete-related industries as a methodology based on Best Available Technologies (BAT). It emphasizes the need for 'transition design' across industries to address CO2 emissions from cement…

This paper reports the flight verification of a high-temperature superconducting motor for aircraft decarbonization. A 2.7 kW prototype was designed, fabricated, and ground-tested, then mounted on an unmanned aerial vehicle for a sustained …

Zhihai Huang, Hisahiro Einaga

Researchers at Kyushu University developed a catalyst-free method for low-temperature carbon oxidation by coupling microwave and ozone. This technique significantly reduces energy consumption compared to conventional high-temperature proces…

This study develops a real options model capturing the interaction between renewable energy investment and cryptocurrency mining under uncertainty. Numerical results show that mining increases the value of renewable energy investment and lo…

Habuer, .

To address uncertainty in future energy prices, a Monte Carlo sensitivity analysis was conducted using Oracle Crystal Ball. Annual electricity price escalation, gas price escalation, and feed-in tariff (FIT) changes were defined as probabil…
