Abstract In the 21st century, human beings encounter two major changes in the maritime field: comprehensively developing and utilizing maritime energy resources provide an opportunity to accelerate the global energy transition and cope with the climate change, and comprehensively developing maritime economy is beneficial to further promote maritime ecosystem protection and global ocean governance. Maritime energy is not only an important material foundation to develop a maritime economy, but also a crucial bond between global energy transition and global ocean governance. The vast oceans contain a huge amount of energy resources. With a deepened understanding of the ocean and further development of relevant technology, more maritime renewable energy resources, such as ocean energy, have been explored and utilized, which move forward to largescale and commercialized. At present, the international community has generally established the institutional mechanism for cooperation on the exploration for and utilization of maritime energy resources, which need to be upgraded. In the strategic framework of developing into a major maritime power and promoting global ocean governance, China should adhere to the innovationdriven strategy and strive to advance maritime energy technology. At the same time, China should take full advantage of the following three pillars to ensure energy security, protect the maritime ecosystem, fight climate change, and promote global ocean governance: strengthening multilateral mechanisms for international cooperation; building the maritime energy silk road; and enhancing blue energy partnerships.
