Member News: Roy Stenhouse joins Apollo as Head of Built Environment

Leading engineering and advisory consultancy, Apollo, has appointed Roy Stenhouse as Head of Built Environment within its Sustainable Infrastructure business unit. Roy joins from the Net Zero Technology Centre (NZTC), where he served as Chief Impact Officer and Board member, leading more than £35 million of funded decarbonisation projects. His experience strengthens Apollo’s support for clients across the Sustainable Infrastructure business unit needing clearer routes to lower emissions. 

Apollo’s work in the built environment includes projects such as assessing the use of gas networks to provide resilient, lower-carbon power for data centres, industrial estate heating technology, hybrid heating systems to support social housing stock and assessments of BESS sites. 

Phil Westmorland, Sustainable Infrastructure Director at Apollo, said: 

“The built environment carries a large carbon footprint as well as accounting for significant GHG emissions whilst also an increased focus on improving energy efficiency. Roy will help clients move from plans to performance. That includes network infrastructure, estate decarbonisation, heat networks, grid and power resilience, data centres, microgrids, and new technology designed and delivered the Apollo way.” 

Roy brings 28 years of experience across the energy, infrastructure, and government sectors, with a strong track record in delivering complex, multi-stakeholder programmes that support the transition to net zero. 

Commenting on his appointment, Roy said: 

“The built environment is a large and wide ranging sector covering much of what we see and use every day. Our focus will be on efficiency, new technology, energy delivery, and everything in between. We support clients not only on their net zero journey, but also in day to day operations to help reduce costs and embed more sustainable practices. Apollo’s multidisciplinary advisory and engineering capability means strategy can be shaped, systems modelled, carbon measured, and economics assessed, followed by delivery of projects that work in the real world. I look forward to working with clients, delivering tangible outcomes and expanding Apollo’s capabilities.” 

Roy is a Chartered Engineer (CEng) and holds a BEng (Hons) in Mechanical Engineering.

AREG has played an important role in the growth of Scotland’s renewable energy sector, engaging the supply chain and developing the European Offshore Wind Deployment Centre. However, we are only at the very beginning of the transition that AREG was established to both lead and support so there are still opportunities for companies to get into the constantly evolving renewables supply chain. We look forward to continuing our work together as renewables builds on its place as Scotland’s main source of power, and as we seek to deliver real change in the crucial areas of heat and transport.

Aberdeen & Grampian Chamber of Commerce has worked closely with AREG since its formation. The recent progress in the developments of offshore wind projects by Equinor and Vattenfall are as a result of the work of the group over many years. The north-east is known as the oil and gas capital of Europe. At the Chamber, we believe the region must evolve its position to being recognised as the energy capital. Whilst hydrocarbons will continue to be essential in driving our economy for years to come, the generation of renewable resources will play an increasingly important role in providing cost-effective power, innovative development and economic growth.

The enthusiasm and dedication of the early group that would become AREG was fundamental in us choosing to launch All-Energy in Aberdeen. The first tiny show was held in 2001, and AREG’s Chairman at the time, Jeremy Cresswell, played such an active role that I often describe him in terms such as All-Energy’s ‘midwife’. All-Energy is now the UK’s largest renewable and low carbon energy exhibition and conference in terms of number of attendees, space booked, and number of exhibiting companies. As AREG became firmly established, their presence and support for the event grew spectacularly over the years. We thank them most sincerely for their invaluable input.

Vattenfall has forged a strong working relationship with AREG through the development of the European Offshore Wind Deployment Centre. AREG has worked tirelessly on behalf of the North East and it can take enormous credit for the growth of sustainable energy in the region and the path it has cleared for the region to capture further investment.

Aberdeen City and Shire is emerging as a key location for renewables by successfully transferring its world-class oil and gas expertise into the sector and AREG has done much to advance this through a broad range of initiatives. It has acted as a catalyst in driving further investment in the local economy by engaging with companies, Government, public bodies and existing projects and we have been pleased to support their efforts. Scottish Enterprise will continue to engage with AREG as we increase Scotland’s use of renewable energy.
