Connect to the people and companies with the power to deliver a decarbonized future at Cleantech Forum San Francisco on 27-29 January 2020.

Since 2002, we’ve brought together global investors, innovators, corporates and change makers looking for answers to the biggest question: who will lead the transformation we’re all waiting for?

This year, the theme of the Forum echoes the growing pressure to deliver solutions: Welcome to the Chaos of the 2020s: Urgent Actions, Unusual Strategies, Unexpected Allies. Join us for three days of opportunities to discover how to succeed in increasingly turbulent times. In San Francisco, you’ll find the people and ideas that matter and leave with the contacts and network to help you take the next steps.

Who Attends

The Forum connects the latest generation of start-ups with investors and corporates looking for new partners.

Meet the people who attended our 2020 Forum.


What People Have to Say About the Forum

“One of the best conferences I have ever been to”
Gregorio Oberti, Managing Director, PwC

“Startups, entrepreneurs, investors, corporates – all the most influential leaders and innovators of the global cleantech industry gather at Cleantech Forum San Francisco to attend meaningful discussions and identify new trends, emerging innovations and their deployment. It really is a MUST in the cleantech industry.”
Andrée-Lise Méthot, Founder & Managing Director, Cycle Capital Management

“It was an absolute blast! Loved my first Cleantech Forum. What amazing people you gather. Feeling inspired and motivated.”
Claire O’Connor, Senior Advisor, International Affairs, US Department of Energy

“Thank you for a great forum! I was humbled by the smart and experienced people I met, it was great rubbing shoulders with such intelligent people. And I’m following up with several of them!”
Kathy Giori, Vice President, Arduino


Welcome to the Chaos of the 2020s: Urgent Actions, Unusual Strategies, Unexpected Allies

Our 2020 Forum theme Welcome to the Chaos of the 2020s: Urgent Actions, Unusual Strategies, Unexpected Allies will highlight what is occurring in response to the somewhat abnormal and chaotic next decade ahead (compared to the 2010s).

By 2030, we have the inconvenient challenge of needing to have halved carbon emissions globally, and we are clearly not on track. Meanwhile, societal forces are gathering in strength year on year to push brands, employers, elected governments, etc. into doing a whole lot more at pace.

Read more

All of this has us thinking that orderliness and the normal pace of things might go out the window, and corporations will have to struggle with the need to do more faster and adopt different strategies (where survival over growth might become the predominant imperative for a while). Part of adopting different strategies and transforming industries will also require different thinking and new business relationships.

Join us for Cleantech Forum San Francisco, and come ready to discuss new and innovative solutions to our pressing climate crisis.

    Changing the Rules of the Game for the 2020s: Ditching Dogma and De-Rigging the System

    As we hit the 2020s, our last shot at staying within reasonable global temperature rises, we’re excited to have with us Bertrand Piccard, explorer, pioneer and Chairman of the Solar Impulse Foundation. His 2016 Round-The-World Solar Flight, which itself followed his completing the first non-stop circumnavigation of the world in a balloon, was only the first phase in his vision.

    The second phase explains why he is here. The Solar Impulse Foundation is currently selecting #1000 SOLUTIONS that can protect the environment in a profitable way. Bertrand will then go around the world again to deliver these solutions to governments, corporations and institutions to demonstrate to them that more ambitious policies and more rapid action programs are possible. The solutions exist. The demand-side is the problem.

    Read more

    Believing that way more needs to be done by policy to grip the climate emergency (and its inherent opportunities) and to tilt the balance of the playing fields, to accelerate the adoption of sustainable and transformative innovations, Cleantech Group is committed to do what it can to help Bertrand and the Solar Impulse Foundation’s mission. Nothing could be more beneficial for this innovation community than people with the right access loudly and unapologetically lobbying for fast change to the rules of the game, and pushing back on the powerful forces at play, who are casting doubts and slowing change down.

  • Olympic Room
    Extra Time with Bertrand Piccard, the Solar Impulse Foundation and their #1000 SOLUTIONS program

    The main plenary room needs to be vacated at 6pm sharp. Bertrand and the team from the Foundation welcome anyone to come across the foyer to the Olympic Room and spend some time with them to follow up from his keynote and hear/learn more about becoming one of their #1000 SOLUTIONS. No more than 50 can be allowed into this room at any one time.

    Welcome to the Chaos of the 2020s: Urgent Actions, Unusual Strategies, Unexpected Allies

    We think it would be fair to say our theme is in good health, certainly compared to a few years back, and that, all things being equal and normal, we’d be justified to expect tailwinds to bring more progress and success over the coming decade, were it not for one inconvenient issue. It’s 2020 and we see no reason to expect anything other than a totally abnormal decade. By 2030, the world faces the inconvenient challenge of needing to have halved carbon emissions globally, and we are clearly not on track. They continue to rise.

    Read more

    We will introduce our overall Forum theme and provide some examples of the urgent actions, unusual strategies and unexpected allies we might see in the 2020s. We are expecting (and indeed hoping for) a totally abnormal and chaotic decade. If it isn’t, we will surely have achieved systemic lock-in to climate suicide, and attention and capital will shift from mitigation solutions to adaptation (some of which will be featured in the pre-event Climate Resiliency Summit).

    2-3 guest speakers will join the discussion to provide their own take on the 2020s, on both what could and should happen.

  • Metropolitan Foyer
    Networking Break

    From this point on, the majority of the Forum’s programming will take place in parallel tracks, offering you a wider variety of subjects to choose from and continuing our more casual and conversational Interaction Track.

    Time to be Inclusive and Pragmatic Before It’s Too Late: Advanced nuclear technologies must be a significant part of the solution set

    At this Forum in 2010, we recognized the good work and leadership of the Ecopragmatist, Stewart Brand, with an award. Ahead of his time, he was then explaining why, to solve the challenges we have of rising energy demand with a need for radical decarbonization at scale, nuclear had to be part of the solution set – including the newer, innovative versions that promise a revolution in economics and industrial utility for nuclear energy.

    Read more

    A decade later, this is still not accepted wisdom, and the runway to climate success is now ten years shorter. This session will explain the 2020 context, why and how innovations in nuclear energy have to be part of the solution set, and when, by using three examples of applications: electricity, industry and transport use cases.

    Urban Mobility: Lessons Learned and Future Innovative Solutions

    Mobility services are creating more congestion, more emissions and more frustrations in cities. With almost 70% of the world’s population expected to be in urban areas by 2050, ride services and micro-mobility (bikes, scooters, etc.) may become part of the solution, but have overwhelmed cities whose already overloaded infrastructure was designed for personal cars, trucks and varying degrees of public transit. In addition, new technologies (autonomous vehicles, connected vehicles, etc.) are ushering in new mobility models.

    Plastic in the 2020s: A rags to riches story?

    Plastic has been a revolutionary substance, but since its invention over 100 years ago our appetite for plastic continues to grow at an alarming and dangerous pace. Plastic is overflowing in our environment, threatening ecosystems and the resources they provide. However, the emerging solutions to close the loop on plastic from design to end-of-life are vast. This session will explore these innovations from biodegradable additives, to sensors which could reduce contamination and many more. We will also focus on corporate decision making and sustainable trade-offs, how to improve the system which underpins plastic recycling and whether innovation can enable a profitable trading market for waste.

    OK, Boomers: Let’s get serious on where we really are and what together we need to get done!

    We thought it would be fun to end the day with a non-confrontational and non-digital cross-generation interaction between two pioneer investors in our field (the “Boomers”), fielding questions from and putting questions to, two upcoming future leaders, with a particular focus on how they all see the decade ahead in terms of trends and business scenarios. 2030 (and the goal of halving emissions) is less than 10 years away.

    Areas of discussion will likely range from what might happen (as ugly as that could be) to what they hope will happen to address the critical problem set.

    Lunch Session: Power-to-X: Storing renewable energy by converting power into X (gas, fuels, chemicals, or other products)

    Power-to-X is an emerging topic of interest across the energy industry used to reference technologies that create new opportunities for the use, conversion, and storage of surplus electric power. As renewable generation continues to grow worldwide, more and more areas face constraints in effectively placing power generated into the hands of consumers due to lack of load growth, transmission constraints, or mere over-supply. As such, Power-to-X markets have emerged, with technologies utilizing power to create fuels, chemicals, gas, and other products. In many cases, renewable power in Power-to-X, creates a carbon free replacement for existing feedstocks in a range of processes.

    In this one hour lunch workshop, a panel of individuals from a variety of industries will share their viewpoint of the Power-to-X field, and what exciting technologies have emerged in recent years
