The future of long duration energy storage is here
We are Elestor
With a focus on decarbonization and societal impact, we aim to revolutionize the energy system, create green jobs, and contribute to a clean, resilient, and inclusive energy future.
Elestor was founded in 2014 by Wiebrand Kout, an experienced scientist. Kout was convinced that he could invent a technological solution to one of society’s greatest challenges, namely climate change.
The following year, he was joined by physics graduate and seasoned businessman Guido Dalessi. Dalessi was impressed with Kout’s vision for a new, clean energy system with robust electricity storage at its core.
The two went on to recruit a team that would fine-tune and expand Kout’s invention.
They also secured investment from some of the most forward leaning forces behind the energy transition.
In the process, Elestor has earned the respect and trust of both policy makers and the general public.
Elestor believes a clean and sustainable energy system will soon be at the very core of society. Large-scale, long-duration and affordable electricity storage will be at the very core of such an energy system, in the form of bi-directional power plants that will replace current plants powered by coal, gas or oil.
The power of renewables coupled with electricity storage extends well beyond their ability to supply affordable electricity to households, transport and industry. Tomorrow’s inclusive energy system will also provide clean air in cities, stable global temperatures that help reduce the damage caused by natural disasters, and economic prosperity that will arise from the thousands of green jobs in the energy sector and in the many new industries it will support.
The energy transition will unify the interests of the Planet, the People and business Profitability.
Reducing electricity storage costs to the absolute minimum will aid the creation of a new, clean energy system.
Elestor will do this in partnership with other players in the renewable energy industry, with committed, long-term investors, and with policy makers at both local, national and international levels.
This energy system will be based on three pillars:
One, renewable energy generated by solar and wind.
Two, large-scale, low-cost and long-duration energy storage that ensures electricity is available also when there is no sun and wind.
Three, sophisticated micro-grid, electricity grid and hydrogen pipeline infrastructure that helps distribute clean electricity to those who need it, whenever they need it.
Guido Dalessi, Chief Executive Officer
Guido Dalessi joined Elestor in May 2015, and is also one of the investors. He is a physics graduate (1986) who started his career in R&D of laser based measuring equipment. In 1996, he joined a high-tech startup, which developed high-tech equipment for optical disc production. As Director Sales & Marketing, Dalessi initiated the international business activities, established a sales and service network with global coverage, and headed local branch offices in Singapore and Los Angeles.
In 2004, the company was acquired by the publicly listed Singulus Technologies AG, after which Guido was promoted to Executive Vice President. Two years later the company acquired its main competitor and Dalessi was appointed CEO, where he managed the merge of both enterprises into Singulus Mastering BV. During his eight years in charge, the company rose to become the global market- and technology-leader in its field.
Pieter Pijper, Chief Financial Officer
Pieter Pijper joined Elestor in August 2023 , and is also one of the investors (MBI). Pieter Pijper, CFO
With an educational background in Business Economics, Pijper has enjoyed a successful career that spans more than 30 years in business. He has always been active in internationally operating organizations – amongst others Deltares (formely known as Delft Hydraulics), Oranjewoud/Antea Group and Strukton Group – companies with technical DNA at their core, resulting in cooperating with passionate experts and engineers. This mirrors the current situation at Elestor.
During his period as Group CFO of Oranjewoud N.V. (2010-2018) Pijper guided a buy and build strategy that resulted in a revenue increase from €300m to €2,300m and saw staff numbers rise from 3,000 to 10,500.
Aided by rigorous financial structures, Pijper will help ensure the rapid commercialisation of Elestor’s hydrogen bromine flow battery technology.
Wiebrand Kout, Founder & Chief Technology Officer
Wiebrand Kout founded Elestor in 2014 to fill the need for large scale, ultra low cost electricity storage. Kout is responsible for the development of the company’s core technology, intellectual property, cost modelling and product planning.
Previously during his career, Kout has pioneered three hydrogen electrochemical systems: the PEM fuel cell, the electrochemical hydrogen compressor and the Elestor HBr flow battery. Prior to founding Elestor, he served as COO and lead designer at HyET, where he co-developed the first electrochemical hydrogen compressor capable of reaching 1,000 Bar in 2013. Today these noiseless hydrogen compressors are considered for use in hydrogen refueling stations by Shell Hydrogen.
Kout started his career in 1999 at NedStack Fuel Cell Technology, where he headed the mechanical design of Europe’s first series produced PEM fuel cell stack. This fuel cell, which is still in production today, is used in several Megawatt scale power plants around the world.
Hylke van Bennekom, Chief Operating Officer
Hylke van Bennekom joined Elestor in April 2021 to lead the operational transition towards large-scale production, and is also one of the investors (MBI). With an educational background in Industrial Business and Administration, van Bennekom joined Tempress Systems in 2007. From various operational roles he had a key position in Tempress’ advancement from a niche player in the semiconductor market to innovative high volume manufacturing in solar and semicon applications. Over time gaining a broad international experience in strategic sourcing, establishing independent production locations in Europe as well as Asia, onboarding of M&A’s as well as an extensive experience in managing change processes within rapidly growing companies.
After obtaining his Master in International Business (MBA) in 2018, van Bennekom played a key role in the disaggregation and privatization of the divisions within in the Tempress Group, leading to the sales of all divisions as independent companies in 2020.
