‘Smart Energy’ camp opens eyes to promising energy-saving solutions

Energy-efficient equipment and materials were showcased recently at a demonstration camp set up at the military exercise “Capable Logistician 2013” in Slovakia in June. Over 500 visitors had their eyes opened to the security issues surrounding fuel supplies for deployed forces as well as to potential energy efficiency concepts and projects for the military.

Fuel convoys in Afghanistan have often come under attack and suffered casualties. “We are trying to make soldiers and commanders understand that saving energy has a direct effect on soldiers’ lives and security. It frees up capabilities for NATO’s core mission that are currently diverted for protecting fuel convoys,” explained Dr Susanne Michaelis, Smart Energy Action Officer at NATO Headquarters.

Germany, the Netherlands and the United Kingdom contributed equipment and materials to the ‘Smart Energy’ camp, including insulation for tents, an intelligent power storage and management system, solar panels and energy-saving light-emitting diode (LED) lights.

Reducing fuel consumption

One VIP visitor, Slovak President Ivan Gašparovič, was particularly interested in a Dutch initiative for producing electricity through solar cells.

“By using the sunshine during the past three days of the exercise, we produced about 35 kWh, most of which is fed into the Slovak power grid,” explained Lt Col Harm Renes, an expert from the Royal Netherlands Army. “Last year in Afghanistan, we installed 480 square metres of solar panels which currently produce 200 kWh per day. The investment has already paid off.”


The team of the CL13 Smart Energy camp included representatives of the British Ministry of Defence, the Royal Dutch Army, the German Fraunhofer Institute Chemical Technology and NATO.

Tom Barker of the UK Ministry of Defence demonstrated an intelligent power storage and management system that has proved successful in reducing fuel consumption in the British project ‘POWER Forward Operating Base’ (POWER FOB). The system allows the incorporation of any renewable energy source and energy-saving technologies.

POWER FOB proved that this power management system could typically save up to 30 per cent of fuel by storing the electricity produced by diesel generators and solar panels and redistributing it when and where required,” explained Mr Barker.

In addition, the POWER FOB project has shown that insulation material, load prioritisation and training could reduce diesel consumption in military camps even further. There are currently about 100 forward operating bases in Afghanistan, some of which could greatly benefit from such a system.

The Fraunhofer Institute for Chemical Technology, Pfinztal, Germany demonstrated a prototype of a portable hydrogen fuel cell that generates 2 kW of electricity, which was developed for the German Bundeswehr.

The hydrogen needed to fuel the cell can be produced using solar energy to split water into oxygen and hydrogen – a silent and environmentally friendly process,” said Dr Karsten Pinkwart. In future, such light-weight fuel cells could replace heavy diesel generators with the same dimension and power output.

Identifying best practices

In addition to raising awareness, the Smart Energy camp had another important goal: to help NATO’s Smart Energy Team (SENT) to formulate recommendations for improving NATO’s standards and best practices on saving energy.

Set up after the Chicago Summit in May 2012 and financed through the NATO Science for Peace and Security Programme, SENT is jointly directed by the Lithuania-based NATO Energy Security Centre of Excellence and by the Joint Environment Department of the Swedish Armed Forces. It is made up of experts from eight nations, including six Allies (Canada, Germany, Lithuania, the Netherlands, the United Kingdom and the United States) and two partners (Australia and Sweden).

The Team’s overarching goal is to identify the most promising energy-saving solutions and initiate multinational projects to make such solutions work together easily.

Towards the ''Green Soldier'' - Reducing fuel dependency in theatre 15 May. 2010 Fuel convoys in Afghanistan have often come under attack and suffered casualties. NATO and individual Allies are working towards energy efficiency and renewable energy technologies to reduce the dependence on fossil fuels and the logistical footprint of deployed troops, while enhancing their security.

Towards the ''Green Soldier'' - Keeping powered up in the field Solar panels are available as portable or wearable equipment. The person seen here is wearing a ''SWIPES'' (Soldier Worn Integrated Power Equipment System) - a portable power system built into a combat jacket, which enables soldiers in the field to power high-tech equipment. The jacket'™s two 150-Wh batteries each weigh almost a kilo, which is 30 per cent less than standard batteries. SWIPES jackets are easier to handle, reduce fatigue and cut the time needed to recharge the battery. 
Towards the ''Green Soldier'' - Making the most of the sun Using solar panels to generate electricity is one option for reducing fuel consumption. In October 2012, the Royal Netherlands Army tested their use at a 480 m2 field in Mazar-e-Sharif, Afghanistan. Currently producing 200 kWh per day, these solar cells made a return on investment in just nine months. (Photo courtesy of Dutch Ministry of Defence)

The shelter is made of flexible material and has advanced thermal insulation, photovoltaic panels and light-emitting diode (LED) lights. 
Towards the ''Green Soldier'' - Better insulating tents Lining a standard military tent with white insulation material reduces fuel consumption when heating or cooling is needed. The material was developed by DESTECH Technology Delivery Logistics Systems for the UK Ministry of Defence and tested in the British ''POWER Forward Operating Base€'' in 2011-2013. 
Towards the ''Green Soldier'' - Re-using shower water The United States has developed a shower water re-use system that recovers, purifies and recycles domestic waste water. The water that emerges is considered to be drinkable according to current quality standards. The system can treat up to 45,000 litres of water per day, of which 75 per cent are re-usable, saving some 34,000 litres of water per day. Over a year, it is estimated that the army could save over 12.1 million litres of water with just one such system. The system can be set up by two people in 30 minutes and operates automatically without supervision. 
Towards the ''Green Soldier'' - Storing and managing power intelligently 17 Jun. 2013 Storing surplus energy from diesel generators and renewable energy producers, this intelligent power storage and management system then distributes the energy when and where needed. The system was tested in 2011-2013 under the British project €œ''POWER Forward Operating Base''€, where it reduced fuel consumption by an average of 30 per cent. 
Towards the ''Green Soldier'' - Using hydrogen to produce electricity This prototype of a portable hydrogen fuel cell produces 2 kW of electricity. In future, such lightweight fuel cells could replace heavy diesel generators with the same dimensions and power output. The fuel cell was developed for the German Bundeswehr by the Fraunhofer Institute for Chemical Technology (ICT), Pfinztal, Germany, together with the company FutureE Fuel Cell Solutions GmbH.
