Blockchain Executive Summit NY - Oct 2018 - Slides
| 9 November 2018
Over the past three years, blockchain technology’s potential to disrupt energy and mobility markets has been the topic of much hype and discussion. After the first trades of 2016 and the record investments of 2017, 2018 is the year blockchain is looking to scale up, especially in energy settings. However, getting to scale means overcoming significant technical, commercial and regulatory challenges. For three years, Cleantech Group has been at the forefront of covering this innovation wave, and helping our corporate, investor and government clients navigate it and make the right connections. After a successful first executive summit on the topic in November 2017 in Boston, we repeated the experience this October, and gathered a group of top executives from energy, industrial and mobility corporates, along with top innovators in the field. We switched our focus from use cases to the scale-up challenge.

Blockchain technology is currently one of the hottest topics in energy innovation. The number of investments, partnerships and consortia between start-ups and corporates keeps growing, and an increasing number of use cases are being piloted.

A Discussion on Innovation in Water Amidst Drought Conditions
| 10 December 2014
In September, innovators, cor porates, utilities, investors, and other stakeholders in the water sector gathered in Berkeley, California, in the shadow of the state’s severe drought conditions. Indeed, the wide ranging discussions at Cleantech Group’s third annual Water Innovation Summit all seemed to draw on the sense of urgency in the Golden State. A consensus was reached that this drought must not be wasted; that the case for adoption of innovative solutions toward sustainable water use must be strengthened by it. This was, of course, not the only theme to come out of the two days’ discussions. The gathering yielded several core learnings, of which four will be detailed in this white paper.

Partnering with Corporates -- An Important but Complicated Aspect of Growing Cleantech Companies
| 18 February 2014
In partnership with VantagePoint Capital Partners and Silicon Valley Bank, we have explored the role corporate partnerships play in the growth of cleantech companies. Corporates, with their capital, access to markets, technological know-how, and validation, often seem like obvious partners to help cleantech startups overcome two of their biggest barriers to success: adoption and scale. Yet despite all the noise and recognized importance of partnerships—amongst entrepreneurial companies (“startups”), large established corporations (“corporates”), and investors alike—the success rate from these complex relationships has been less than we expected.
