Technical Presentations from Practitioners, Academia Manufacturers, and other experts – Provisional Speaker List:


1.           100%  zero carbon energy for the UK – Cost and feasibility? Professor Mark Barrett, UCL3.      Energy modeling of UKs optimum energy supply system under various scenarios – chp, nuclear, heat pumps, hydrogen etc (provisional title)

Professor Barrett will talk about his group’s optimization studies of the least cost route to sustainable low carbon, heat, and power for the building, automotive, marine and power sectors.


2.           ‘Nuclear Power: Past present and future’   the full nuclear story, warts and all:  

Professor David Elliott. Open University. Prof Elliot has just completed a book for the Institute of Physics with that title.


3.           On-demand low-pressure hydrogen gas perfect feed gas for Fuel Cells.

A 2/3rd Methanol and 1/3rd H2O mix through a unique reformer can deliver low pressure hyrogen gas on demand.   The H2 mix is a low-pressure gas for PEM Fuel Cells. Fuel cell anodes are immune to trace methanol unlike trace ammonia which is very harmful.  These will deliver H2 gas for loads between 50kW to 500kW equivalent.  This technology is being rolled out in shipping and large trucks/trains. Methanol can be synthesized using renewables.  Its applications are only beginning to be realised.

4.           How to install heat pumps correctly, so they work properly and have a good winter and seasonal COP
Brendon Uys, Managing Director, Heacol.

5.           Marine Cloud Brightening

Stephen Salter. Emeritus Professor of Engineering Design, School of Engineering, University of Edinburgh. 0131 650 5704 or 662 1180.

Getting to zero emissions is highly desirable but totally inadequate on its own, because it will leave behind all that we have released so far PLUS all we will release between now and the zero date. Progress since the Stockholm Earth Summit in 1972 has not been encouraging. In parallel with reductions, we could use an idea by Latham to increase the reflectivity of clouds by increasing the concentration of cloud condensation nuclei to exploit the Twomey effect.  The presentation will explain physics and engineering.



6.           National Grid and low carbon future

Speaker from National Grid – to be announced


7.           Britain’s nuclear future.

Speaker from the nuclear industry – – to be announced


8.           Beyond space heating and cooling – Professor Bill Bordass

A century or more ago, space conditioning was progressively turned into a commodity. For example, in Air-conditioning America (Johns Hopkins University Press, 1998), Gail Cooper describes the outcome of a battle between advocates of natural and mechanical systems in New York in the 1920s:

“When the natural climate was the ideal, mechanical systems were found wanting, but when quantitative standards … became the measure, natural climate was found wanting.

When no town could deliver an ideal climate, all towns became potential markets.” – GAIL COOPER,

As comfort (often simplified to air temperature) became increasingly dependent on energy-hungry systems, occupants lost skills and abilities to adapt, while many buildings (both old and new) became progressively worse at moderating the indoor climate naturally. The wisdom of this is now being questioned.

But is the concept of space-conditioning itself beyond its sell-by date? The speaker will explore some principles and possible solutions.


9.              Heat Networks: recent progress and their future potential as part of decarbonizing heat

Dr Andrew Cripps.  Technical Director in the Clean Heat team at Triple Point Investment Management

Triple Point are the lead of a team who are the Delivery Partner for HNIP and GHNF, two major BEIS funded capital programmes to support heat networks in England. They form part of the broader Heat Networks Transformation Programme seeking to grow the share of heat supplied through networks from around 3% today to 15-20% by 2050. Through this work he has insight from over 40 projects being planned or built in the UK at present. In this presentation he will share learnings from the technologies used, approaches taken and scale of networks, and how this might progress in future. E W

10.       District Heating for Most of the UK; Far Better than Hydrogen

Gordon Taylor, B.Sc., M.Sc., M.I.Mech.E. Chartered Mechanical Engineer  District heating with hot water is the best match for most of the UK heat load, whereas hydrogen would incur significant conversion and mismatch losses. See my Submission to the House of Lords Select Committee on Hydrogen.



11.       HP with  DH, CHP  and heat pumps, running the BEIS SRBI project to deliver open control systems for renewables including a number of field trials from domestic installs through to heat networks. This includes a few flavours of heat pump including CO2

Richard Hanson-Graville <> We are running the BEIS SRBI project to deliver open control systems for renewables including a number of field trials from domestic installs through to heat networks. This includes a few flavours of heat pump including CO2. They will be fully documented, hydraulically and controls, and there will be real-time data from them all made public so its not based on opinions. (Historically a number of heat pump manufacturers have used us for training on integrating their kit into wider systems, and we have done thousands of domestic systems covering nearly all makes). At least one field trial will include CHP, again all open and documented with data.




12.       Renewables and flexibility markets

Colin Mallett. I have attached a recent paper which would form the basis of my contribution to your conference. However, as this topic is moving very fast, I always create papers from scratch.


13.           Tidal Energy Generation in the Bristol Channel: West Somerset Lagoon

Roger Falconer DSc(Eng) FREng ForMemCAE FEurASc FLSW. Emeritus Professor of Water and Environmental Engineering. Hydro-environmental Research Centre. School of Engineering, Cardiff University, UK. Mobile: +44(0)-7775-640468.

Roger will talk about the opportunities and benefits of tidal range energy and present the case for tidal energy being a key part of the energy mix. By way of presenting his case, he will use the proposed West Somerst Lagoon as an example to illustrate many of his points.



14.        building simulation/prediction of thermal performance and energy use

Eoin Clancy.  Lecturer in the Dept. of Mechanical & Electronic Engineering, School of Engineering, Dundalk Institute of Technology, County Louth, Ireland. Eoin Clancy <>,


15.       Whole-firm transition to working to fully sustainably & to a competitive advantage within environmental and Climate limits – For BMP, after submitting a possibly significant claim to the Serious Fraud Office that has held us back a long time, our interest is communicating the power of commercially advantageous, Sustainability Transition.

Ross King <  For example, a global, top three property/ construction/ building company with whom we have worked for over a decade, estimates that a universal Sustainability Transition training process over the next 7-10 years is likely to cut emissions and increase profitability by 90-100% and leave it steadily able to work both ecologically sustainably and more profitably than its main competition.
No matter where a firm starts or is now, a universal management process is consistent with, for example, work it has done on the ISO Environmental & Energy Management Standards, and just lifts it to another level that is also consistent with zero Climate Change and ecological damage and increasing commercial advantage. It also makes staff and stakeholders at all levels a lot happier.

I and three colleagues have led such developmental training processes (real site/ real time/ hands-on) on over 60 sites for mostly blue-chip operations including BA, BP, the RAF…



16.       How an Exergetic,  Second Law of Thermodynamic analysis can optimise energy resources.

Willam Orchard, Orchard Ptnrs


17.           Sustainable Biomass Fuel for C21 Owes Much To UK Investment in C20

Tom Jarman. Director, Biocentre Resources Ltd. Brief Synopsis: In the 1980’s and 1990’s the UK perfected a process to produce a high biomass, low chlorine, high CV pelletized fuel from residual waste, successfully used for many years in place of wood pellets and coal in industrial processes and boilers. With the emergence of the Waste Incineration Directive this technology all but disappeared as long-term Council contracts drove a focus on Energy from Waste plants. We now again recognize the carbon and cost benefits of a process with best-in-class OPEX, CAPEX for a high quality sustainable 90% biomass fuel. This paper looks at the process and fuel performance evidence and argues that the time has come for this technology to be rediscovered.
