Introducing our 2019 Sponsors

The global energy sector is experiencing massive change in the areas we call the 4D’s. Deregulation has opened the market to competition and a strong need to make distinctly valuable product offerings. Digitalisation has forced the energy sector to consider the impact of new data streams and how to capitalise on them. Decentralisation has turned the idea that energy must come from a single power plant on its head, as anyone with a solar panel and battery can effectively generate energy. Decarbonisation has followed the global imperative that we must reduce carbon-intensive forms of energy generation in order to mitigate climate change.

Japan is embracing these 4D’s strongly and at an enormous scale. Accelerating the global energy transition and facilitating innovation in the Japanese energy sector is an ambitious goal, and our sponsors for Japan Energy Challenge 2019 exhibit a spirit to be the leaders in this transition.

With the senior decisionmakers for these companies arriving in August for a week of events focused on energy sector innovation, it’s going to be an exciting event. Collectively, they control a commanding portion of the Japanese energy market, so the solutions that are a success at JEC2019 will have a great opportunity ahead of them. We look forward to welcoming them this year and working to advance the industry as a whole.
