I first met Pete Armstrong as he was pitching at the Ecosummit event in Berlin in 2018 and last year. The scale of the impact possible in transforming our heating and water storage systems in our homes blew my mind. I’ve always been so involved in the ‘electrification of everything’, so I’ve watched since with interest. Mixergy were also mentioned in a recent podcast episode with Robert Trezona of IP Group, one of their early (and follow on) investors. So I thought I’d invite Dr Pete Armstrong to join us.

About our guest

Dr Pete Armstrong is CEO and co-founder of Mixergy, an Oxford University spin-out company which has brought to market a unique hot water tank. Pete completed his PhD on intelligent hot water tanks at Oxford Uni with fellow student and co-founder Ren Kang, before going on to win a Technical Innovation award within the 2013 Shell Eco-Marathon electric car competition, and a prize in a Climate KiC venture competition, which was the genesis of Mixergy in 2014. Mixergy has since received investment from IP Group, Oxford Science Innovation, Centrica Innovations and Foresight Williams to grow and develop the business.

About Mixergy

Mixergy has developed an intelligent hot water tank, which is unlike others on the market. The Mixergy tank operates on an integrated Internet of Things platform and is designed to selectively heat smaller portions of water. As a fleet, Mixergy aims to offer a Demand Side Response (DSR) service to the National Grid, absorbing excess power load and time shifting demand to help balance the grid. This “Internet of Tanks” vision will help to facilitate the generation and utilisation of more renewables nationwide to support a greener future. The Mixergy tank is also a benefit to consumers, saving up to 40% on hot water bills through sophisticated machine learning.

What’s it all about?

At Hyperion we love all things energy storage, and we’re always following new companies and technologies that can and will enable the energy transition. I recently met the team from Gravitricity at a trade show I was speaking at, and liked the look of their solution, anything that uses old and established technologies for new and innovative solutions is good as far as we’re concerned, so we asked their MD Charlie Blair to share more.

About our guest

Charlie joined Gravitricity as a founder shareholder in 2015, having worked with co-founders Peter Fraenkel and Martin Wright while in the Innovation Team at the Carbon Trust.  The team has grown since then and he’s been instrumental in developing the strategic relationships with manufacturing partners that will allow the technology to get to market fast.  Gravitricity is currently building at 250Kw, 50 tonne, Concept Demonstrator in Leith, Edinburgh.   Charlie has a Geography degree from Durham University and an Energy Systems MSc from Imperial College. He was elected a Fellow of the Energy Institute in 2019. 

Gravitricity is an energy technology company based in Edinburgh developing groundbreaking underground storage.  Grid-scale electricity storage spend is projected to grow from around $3 billion per year today to over $50 billion per year by 2040.   

Gravitricity’s patented technology is based on a simple principle: raising and lowering a heavy weight to store and release energy. The Gravitricity system suspends weights of 500 – 5000 tonnes in a deep shaft by a number of cables, each of which is engaged with a winch capable of lifting its share of the weight. Electrical power is then absorbed or generated by raising or lowering the weight. Gravitricity technology has fast response (<1s), extremely long life, high efficiency and levelised cost of storage almost half that of chemical batteries.   The technology will initially be deployed at existing mine-shafts; later on in purpose-sunk shafts exactly where the grid needs storage.

What’s it all about?

Solar power is my first love, and whilst in recent years it has been battery storage, EV Charging infrastructure and eMobility that has dominated my work at Hyperion, we’ve kept our love for and focus on the solar industry. I was introduced to Haggai by Ulrich Seitz at Bay Wa Ventures, and I love what they are doing. As ever it’s another great start-up story for an entrepreneur with a passion to make a difference to the world.

About our guest

Solar energy has been part of Haggai Hofland’s life for as long as he can remember. The CEO and founder of Raycatch was born and raised on a kibbutz in the Arava Desert in southern Israel, where his father built one of Israel’s largest solar energy companies. Solar energy has been the most installed energy source in the past few years. At Raycatch we believe that cutting-edge software will make it even more cost-effective and will enable a higher global adoption rate. The next leap in solar adoption will be led by the data revolution!

The Raycatch team includes solar industry experts and serial software entrepreneurs and the company is successfully enhancing over 2.5GW in solar assets worldwide. Raycatch’s leading solution, DeepSolar, is a pure SaaS AI solution that provides actionable insights for solar asset owners and operators to significantly enhance yield and improve asset ROI.

Haggai holds a B.A. in economics and management with a specialization in entrepreneurship, and has been working in tech companies in the renewable energy sector since 2010.

He is passionate about creating tech solutions for real-world problems with a global impact. Prior to Raycatch, Haggai co-founded Webper, a start-up that personalizes feeds in content websites and served as VP Business Development at Brighttech, a leading Israeli software developer. Haggai also advises public companies in PV production and data analysis of renewable energy assets.

What’s it all about?

I first heard Billy Wu speak at a renewable energy event in London about four years, and my inner battery nerd was born and thrust into the world. Dr Billy has the knack of being a fully fledged Dr of batteries, whilst being able to articulate to non scientific nerds like me, and possibly you, if you are reading this.  We talk batteries, supercapacitors, and of course Hydrogen Fuel Cells, where we are, what’s next, and who will win!

About our guest

Dr. Billy Wu is a senior lecturer in the Dyson School of Design Engineering at Imperial College London where he co-leads the Electrochemical Science and Engineering group. His research activities include: energy storage/conversion technologies (lithium-ion batteries, redox flow cells, supercapacitors and fuel cells) and manufacturing (3D printing, nanofibre electrospinning).

He has published 35 peer reviewed journal papers, 2 book chapters and 4 patents since completing his PhD in 2014 and sits on the editorial board of Scientific Reports. He has been an investigator in research projects worth in excess of £46M, directly managing a budget of >£2M and is a co-investigator for the UK Faraday Institution battery research centre. He directly leads a team of 7 post-docs and 6 PhD students within the wider Electrochemical Science and Engineering group which has >50 researchers. Prior to his PhD in automotive proton exchange membrane fuel cell-lithium-ion battery hybrid systems, he completed his masters in Mechanical Engineering from Imperial College London in 2010.
