Optimising thermal store design for CHP

In his second instalment on modern CHP design, Remeha’s Ryan Kirkwood explores use of thermal stores and how this can maximise CHP efficiency

Danish district heating – The heat of the moment

Copenhagen’s district heating relies largely on biomass and waste incineration power plants, but net-zero carbon targets are now encouraging suppliers to harness energy from renewables and industrial by-products. Alex Smith reports

Making the switch from gas-fired CHP to heat pump

Lower carbon factors for Grid electricity proposed for Part L are already in place in London. Andy Pearson looks at one scheme in North London where the design is switching from gas CHP to heat pump

Showcasing net-zero: Event Complex Aberdeen’s energy strategy

The Event Complex Aberdeen has a sophisticated energy strategy combining anaerobic digestion, hydrogen fuel cells and CHP plant. Andy Pearson talks to HDR | Hurley Palmer Flatt about the system design, which also produces hydrogen for a fleet of local buses

A condensing guide to CHP efficiency

CHP can offer savings in applications with high, constant heat demand, but how designers integrate it will impact on the benefits. Remeha’s Ryan Kirkwood considers the options in the first of a two-part series

Tackling NOx from CHPs

Policies encouraging gas-fired CHPs in London are going into reverse. David Blackman looks at how new air pollution policies will affect the future of heat in the capital

On the right track: services retrofit saves TfL’s Palestra £400,000

Like most large offices, TfL’s Palestra building is complex. To realise its true potential, it underwent significant interventions resulting in £400,000 of energy savings. Andy Pearson explains how an energy performance contract made the building 6% better than good practice

Why gas CHP still measures up

Despite the rapid decarbonisation of the UK electricity grid and lower wholesale prices, properly sized combined heat and power with thermal storage still offers an economic, lower-carbon energy option, explains director of Carbon Alternatives Martin Crane

National Gallery of Ireland’s hidden services

Refurbishment of the National Gallery of Ireland required tight environmental control in the galleries, but there was minimal space to make this happen, writes Chris Croly
