天然气助力未来世界发展——第27届世界天然气大会(WGC)综述

以天然气为代表的低碳清洁能源是当前世界能源行业关注的热点。第27届世界天然气大会(WGC)于2018年6月25—29日在美国首都华盛顿召开,本次会议对过去3年世界天然气业务的发展进行了系统回顾、展望了发展前景,并达成了以下共识:(1)天然气是低碳、清洁、绿色、多元的"三可"(可靠的、可承受的、可持续的)能源;(2)全球天然气产业快速发展,市场呈现出相对宽松的态势;(3) LNG是目前世界天然气发展的重点;(4)甲烷泄漏与排放已成为公众关注的焦点;(5)天然气的灵活性、碳捕集封存技术和碳排放定价机制成为天然气与可再生能源组成"互补搭档"的推手;(6)提高天然气自给度是平抑区域性价格差异和决定定价话语权的有力手段;(7)争取政府对天然气产业的支持,重视公众的关注和参与。基于在本次大会上所取得的认识与收获,对中国天然气业务下一步的发展提出了如下建议:(1)进一步加大对国内常规和非常规天然气的勘探开发力度;(2)重点补齐工程技术等制约天然气业务发展的关键核心技术短板;(3)统筹考虑天然气上下游业务;(4)加强全业务链甲烷泄漏管控;(5)统筹制定天然气进口贸易对策。

Natural gas fueling the world's future: A brief summary from the 27th World Gas Conference (WGC)

Natural gas, one of low-carbon energy sources, has become great concern of the global energy industry. The 27th World Gas Conference (WGC) took place in Washington DC, USA, from 25 to 29 June in 2018, offering a comprehensive and systematic retrospect and prospect concerning the development of world natural gas industry over the past three years. This conference has reached the following common views: natural gas is a kind of low-carbon, clean, green and diversified "reliable, affordable & sustainable" energy source; the world natural gas market displays a relatively loose status; LNG is the focus of the current world natural gas development; methane leakage and emission has become one of the public concerns; the flexibility of the natural gas, the carbon storage technologies and carbon pricing regime have been making natural gas become complemented with renewable energy sources; increasing natural gas self-sufficiency is a powerful means to stabilize regional prices and to decide the price fixing right; and to strive for government support and attract public attention and participation. Based upon the information and understandings obtained from this conference, the following suggestions are thus proposed for further development of natural gas industry in China: to make greater efforts to domestic conventional and unconventional natural gas exploration and development; to complement such bottlenecks of key core technologies such as engineering technology; to take into full account both upstream and downstream natural gas business; to prevent and control the methane leakage all through the whole industrial chain; and to formulate policies on natural gas import trade as a whole.
