China Energy Reserve and Chemicals Group is exploring the possibility of importing LNG from the US via ISO containers loaded from the West Coast. Japan is bringing its nuclear reactors back on line following the suspension of operations at all reactors after the 2011 Fukushima accident. As the reactors return to full operation, the increase in nuclear generation is likely to displace generation from fossil sources, in particular natural gas.
Asian spot prices for LNG took a dive to multiyear lows, feeling the pressure of the lack of demand. Holders of previously agreed upon long-term buyer contracts seek renegotiation. The decision follows a previous $10-billion investment in LNG the country made in 2017. While that investment focused on outside energy supply sources, this one will be used to develop infrastructure in Southeast Asia and the Indian subcontinent. The Japanese operator will submit a development plan to the Indonesian government within the next few weeks, with FID for the $20-billion project coming around 2022.
A multibillion dollar boom in petrochemical plants proposed along the US Gulf Coast could pump as much greenhouse gas into the air as 131 coal-fired power plants by 2030, according to a study released by researchers at The University of Texas. Concentrations of carbon dioxide in the atmosphere surged at a record-breaking speed in 2016 to the highest level in 800,000 years, according to the World Meteorological Organization's Greenhouse Gas Bulletin. The abrupt changes in the atmosphere witnessed in the past 70 years are without precedent. The Netherlands will reduce production of its Groningen gas field by 10% from October to limit the risk of earthquakes, the country’s economy minister said in a letter to parliament on 18 April.

This article introduces the composition and 12 operating conditions of a four-engine two-propeller hybrid power system. Through the combination of gearbox clutch and disconnection, the propulsion system has four single-engine operation modes, two double-engine parallel operation modes, and six PTI operation modes. Because the propulsion system has a variety of operating conditions, each operating condition has a form of energy transfer. As a result, its energy management and control are more complicated. To study the energy management and control strategy of a diesel- electric hybrid propulsion system, this work mainly studies the simulation model and sub-models of a diesel-electric hybrid propulsion system. In this study, MATLAB/ SIMULINK software is used to build the diesel engine model, motor model, and ship engine system mathematical model. The test and analysis were carried out on the test bench of the diesel-electric hybrid power system. By comparing the theoretical value of the SIMULINK simulation model with the test value of the test bench system, the correctness of each sub-model modeling method is verified. On the one hand, research on the text lays a theoretical foundation for the subsequent implementation of the conventional energy management and control strategy based on state identification on the unified management and distribution of the diesel-electric hybrid power system. At the same time, energy management of the diesel-electric hybrid system is also carried out. Optimization research provides theoretical guidance.
