Powerhouse Energy Group, a technology company commercialising hydrogen production from plastic, says Allan Vlah wishes to step down as non-executive director on 31 December 2021 to concentrate on other business interests.

The Bingley-headquartered company also says it has appointed Keith Riley, 72, as a non-executive director with immediate effect.

Riley is currently proprietor and chief executive officer of Vismundi Limited, a consultancy company providing services to the resources and waste management industry.

Prior to that, between 2005 and 2012 he worked for Veolia Environmental Services plc as group managing director for technology and as managing director for Group Technical Services.

Over the course of his career he has worked with a number of specialist waste and resource management companies and most recently has been non-executive director of Waste2tricity Limited.

He continues to be a partner of BH Energy Gap LLP on behalf of Vismundi, which develops projects in the renewables sector and raises the finance to implement them.

On joining the Board of Powerhouse, Riley said: “The DMG technology being developed by Powerhouse addresses two important issues – the need for energy free of climate change impacts, and the excess of plastic waste.

“I am pleased to be able to join the Board to help further the business of Powerhouse in addressing these two issues.”

James Greenstreet, non-executive chairman, added: “On behalf of the board I would like to thank Allan for his invaluable contribution over the last year and wish him well in his future ventures.

“I am delighted to welcome Keith who brings a wealth of relevant experience to the Board and very much look forward to working with him as we move Powerhouse forward.”


Leeds-based health software business, EMIS Group, has appointed Denise Collis to its Board as an additional independent non-executive director.

She will formally join the Board on 1 October 2021 and will be a member of the audit and nomination committees, as well as chair of the remuneration committee.

Collis has a breadth of business experience with a particular focus on people and talent management, development, retention and reward which the Group believes is particularly relevant given the heightened focus on employee engagement, communications and wellbeing.

She is currently non-executive director, chair of the remuneration committee and senior independent director at SThree plc and non-executive director and chair of the remuneration committee at Smiths News plc.

Her last executive role was as chief people officer at Bupa, the global healthcare business, between 2010 and 2014.

Prior to that, she held senior HR roles at a number of leading organisations including 3i Group plc, EY LLP, Standard Chartered Bank plc and HSBC over a 40 year executive career.

Patrick De Smedt, chairman of EMIS Group, said: “It gives me great pleasure to welcome Denise Collis to the Board.

“Denise has a wealth of HR and remuneration expertise gained from a successful career in people businesses, as well as strong business and commercial experience.”
