Countries E4tech is or has been active in

Our clients

E4tech worked closely with a senior team at Johnson Matthey over three months in 2015, helping us to assess the strategic outlook for one of our growth areas. Their team brought tremendous industry insight and contacts, together with strategic thinking and effective delivery, leading to outcomes that were well-received by the Executive Committee and the Board. I would be very pleased to work with E4tech again.

I have great pleasure in recommending E4tech to future clients. ETI has worked with E4tech since 2010 across a number of Bioenergy-related projects, encompassing a variety of technical, economic and environmental analyses of the UK bioenergy sector. The most significant piece of work has been the development of the ETI’s Bioenergy Value Chain Modelling toolkit – a circa £1.3 million project led by E4tech. I particularly value E4tech’s attention to detail, thoroughness, speed of working and ability to challenge – both on approaches taken and conclusions drawn.

E4tech have provided very useful insights in the area of quantification of land use change due to crop production, which helped us shape our research strategy. It has been a pleasure working with them in all stages; their professionalism, flexibility of approach, and continued contact allowed tailoring delivery to the evolving study. Their work has clearly benefited from their significant international network, a multidisciplinary team, and an integrated approach.

E4tech were retained to assess bids and carry out detailed due diligence in support of the Polymer Fuel Cell Challenge.   The project was a success resulting in investments being made into four companies.  A large part of this success can be attributed to E4tech’s attention to detail, quality of insight, communication, responsiveness, dedication and commitment. I have no hesitation in recommending E4tech whose work met and exceeded our expectations.
