5 can't-miss innovation events at CERAWeek featuring Houston speakers

where to be online

While usually hundreds of energy experts, C-level executives, diplomats, members of royal families, and more descend upon Houston for the the annual CERAWeek by IHS Markit conference, this year will be a little different. Canceled last year due to COVID-19, CERAWeek is returning — completely virtually.

The Agora track is back and focused on innovation within the energy sector. The Agora track's events — thought-provoking panels, intimate pods, and corporate-hosted "houses" — can be accessed through a virtual atrium.

Undoubtedly, many of the panels will have Houston representatives considering Houston's dominance in the industry, but here are five innovation-focused events you can't miss during CERAWeek that feature Houstonians.

Monday — New Horizons for Energy & Climate Research

The COVID-19 pandemic has made vivid and real the risks of an uncontrolled virus. Risks posed by climate change are also becoming more palpable every day. At the forefront of understanding these risks, universities are developing solutions by connecting science, engineering, business, and public policy disciplines. Along with industry and governments, universities are critical to developing affordable and sustainable solutions to meet the world's energy needs and achieve net-zero emission goals. Can the dual challenge of more energy and lower emissions be met? What is some of the most promising energy and climate research at universities? Beyond research, what are the roles and responsibilities of universities in the energy transition?

Featuring: Kenneth B. Medlock, III, James A. Baker, III, and Susan G. Baker Fellow In Energy And Resource Economics, Baker Institute and Senior Director, Center For Energy Studies at Rice University

Tuesday — Conversations in Cleantech: Powering the energy transition

With renewables investment outperforming oil and gas investment for the first time ever in the middle of a pandemic, 2020 was a tipping point in the Energy Transition. Low oil prices intensified energy majors' attention on diversification and expansion into mature and emerging clean technologies such as battery storage, low-carbon hydrogen, and carbon removal technologies. Yet, the magnitude of the Energy Transition challenge requires an acceleration of strategic decisions on the technologies needed to make it happen, policy frameworks to promote public-private partnerships, and innovative investment schemes.

Three Cleantech leaders share their challenges, successes, and lessons learned at the forefront of the Energy Transition. What is their vision and strategy to accelerate lowering emissions and confronting climate change? Can companies develop clear strategies for cleantech investments that balance sustainability goals and corporate returns? What is the value of increasing leadership diversity for energy corporations? Can the Energy Transition be truly transformational without an inclusive workforce and a diverse leadership?
