BP Officially Shuts Down Solar Efforts
If "BP" is short for Beyond Petroleum, it will have to change its name to just "P" now after it officially shut down its solar business last month, a key division in its quest to develop cleaner sources of energy. After 40 years, the final decision to shut the door on solar mostly comes from the impossible competition faced from China.
With the growth of Chinese manufacturing, a global surplus of panels and the subsequent collapse in prices, many solar companies have similarly been forced out of business over the last year.
"The continuing global economic challenges have significantly impacted the solar industry, making it difficult to sustain long term returns for the company, despite our best efforts," BP said in an internal letter to staff.
“Over the last six months we have realized that we simply can't make any money from solar,” a spokesman added.
Around 100 staff will be affected internationally and BP's remaining solar interests will be sold, but at least the proceeds will go towards BP's efforts to help recover some of the costs from last year's devastating explosion and oil spill in the Gulf of Mexico.

Furthermore, BP says its move away from solar won't necessarily mean a move away from its broader interests in renewable energy. In 2005, the company said it planned on investing $8 billion in alternative energy by 2015. Thus far, $7 billion has been invested in its U.S. wind power portfolio and biofuels business.
So can you blame BP?
Just as important is BP's failure to capitalize on innovative technologies that would have allowed the company to profit in the solar market. Nathan Stoddard, one BP's own researchers, invented a new way to make silicon wafers for solar cells that significantly cut the cost of high efficiency silicon solar panels. The technology was originally developed in 2006, but never fully commercialized.
Instead, the company spent the next three years in a testing phase, showing it off at trade shows, and shut down its manufacturing operations in 2010. The rights were then sold to the Dutch company AMG.
Publicizing the new technology and failing to mass produce the panels allowed others to swoop in and replicate similar concepts elsewhere. Although AMG has resumed development of the technology, the solar market is stalled and its efforts appear to be too little, too late.
Industry movement with heat decarbonisation
It is estimated that the heat network market requires approximately £30 billion of investment by 2050 to meet the UK Government’s net zero targets, and the decarbonisation of heat has been highlighted as a particular challenge.
The Climate Change Committee’s Sixth Carbon Budget states the UK should target 20% of UK heat demand through low-carbon heat networks by 2050 - but as with most discussions surrounding mass decarbonisation, even reaching that target won't be an easy task. In the UK approximately 40% of energy consumption and 20% of GHG emissions are due to the heating and hot water supply for buildings.
The International Energy Agency (IEA) estimate that globally, around half of all energy consumption is used for providing heat, mainly for homes and industry.

This week saw some positive movement, however, with gas distribution company SGN and UK renewable energy solutions provider Vital Energi announcing a 50:50 joint venture, which will create an Energy Services Company (ESCO) representing utility infrastructure and heat network providers.
This includes delivery of heat to developments planned by SGN’s property arm, SGN Place, and the local vicinities where there is a demand for low-carbon heat.
The objective is to supply new and existing residential, industrial and commercial facilities and development activity is already underway for two projects in Scotland and the South East, with another 20 in the pipeline. SGN is looking to develop alternative heat solutions alongside its core gas distribution business and expand into the growing district heating market, recognising the future of heat is likely to include a mix of technological solutions and energy sources.
Vital Energi is seeking to expand into asset ownership opportunities to complement its core design, build and operations businesses. The complementary skillsets of both organisations will offer a compelling proposition for developers, commercial and industrial users and public sector bodies seeking low-carbon heat solutions.
SGN’s Director of Commercial Services and Investments Marcus Hunt said: “Heat networks are likely to play an increasing role in the delivery of UK heat in the context of net zero. The creation of this joint venture with market-leading Vital Energi enables us to build a presence in this emerging market, delivering new heat infrastructure and supporting decarbonisation.”
Nick Gosling, Chief Strategy Officer at Vital Energi, said: “Combining the resources, expertise and know-how of both organisations will allow us to play a major role in delivering the UK’s transition to low and zero-carbon heat.”
In March, the European Marine Energy Centre (EMEC) starting collaborating with Highlands and Islands Airports Limited (HIAL) to decarbonise heat and power at Kirkwall Airport through green hydrogen technology. 2G Energy was selected to deliver a CHP plant which generates heat and electricity from 100% hydrogen.
Heat decarbonisation options
The Energy & Climate Intelligence Unit (ECIU) highlights the following options for decarbonising heating.
Use renewable electricity to generate heat in the home. As power sector emissions fall, emissions associated with electric heating are decreasing rapidly.
Low carbon gases
Replace natural gas that most homes use for heating with hydrogen, which releases energy but not carbon dioxide, the only waste product is water. Biomethane is also an option as it produces less carbon than natural gas over a full lifecycle.
For hydrogen to work, the pipes in the national gas grid would need to be replaced and home boilers would need to be adapted or changed. This is possible but could incur considerable cost.
Biomethane is chemically identical to methane from natural gas, so is suited to existing infrastructure and appliances. It is unlikely, however, that it can be produced in sufficient quantities to replace fossil gas entirely.
A hybrid system combining both electrification and hydrogen is a third option. Here, heat pumps could be used to meet the majority of heat demand, with a (low carbon) gas boiler taking over in extremely cold weather. Advantages of this approach include helping establish a market for heat pumps while hydrogen is developed to displace natural gas in the hybrid system eventually, and the ability to call on hydrogen when heat demand is at its very highest.
Heat networks connect a central heat source to a number of buildings via a series of underground hot water pipes, and are popular in countries such as Denmark, where heat networks supply 63% of households. The Government expects the heat networks market in the UK to grow quickly to supply up to 20% of heat demand over the next decade or so, investing £320 million into its flagship Heat Networks Investment Project to help get this underway.
Heat networks work particularly well in built-up urban areas or industrial clusters where there is a large and concentrated demand for heat. Over time, it is thought that if the central heat source can be low carbon, then there is the opportunity to ensure that multiple homes and buildings are decarbonised at once.
Biomass can be used to reduce emissions when used instead of more polluting fuels like oil in off gas grid properties. Support for biomass boilers has been available since 2011 via the Renewable Heat Incentive (RHI), but take-up has been low.
Supply constraints also restrict the role that biomass – burning solid material such as wood – can play. In any case, according to the Committee on Climate Change, this resource may be better used in other sectors of the economy such as construction, where it provides carbon storage without the need for CCS and reduces demand for carbon-intensive materials such as steel and cement.
The Energy Transitions Commission (ETC)'s latest report sets out how rapidly increasing demand for bioresources could outstrip sustainable supply, undermining climate mitigation efforts and harming biodiversity, unless alternative zero-carbon options are rapidly scaled-up and use of bioresources carefully prioritised.
"Alternative zero-carbon solutions, such as clean electrification or hydrogen, must be developed rapidly to lessen the need for bio-based solutions," it states.
The overall decarbonisation of industry is another major challenge, especially among four sectors that contribute 45 percent of CO2 emissions: cement, steel, ammonia, and ethylene, according to a McKinsey report.
The process demands reimagining production processes from scratch and redesigning existing sites with costly rebuilds or retrofits. Furthermore, companies that adopt low-carbon production processes will see a short- to mid-term increase in cost, ultimately placing them at an economic disadvantage in a competitive global commodities market.
Ken Hunnisett is Project Director for the Heat Network Investment Project (HNIP)’s delivery partner Triple Point, which is the delivery partner for the government's Heat Network Investment Project, which is responsible for investing up to £320million in strategic, low-carbon heat network projects across England and Wales.
He is calling for the urgent need to invest in the development of new heating infrastructure to support the nation’s decarbonisation effort. So far £165m of HNIP funds have prompted £421m CAPEX, providing more green jobs as the UK economy eases from the lows sustained from the pandemic.
Decarbonising the UK's heating infrastructure is critical if we are to reach our net-zero goals and it’s crucial that progress is made in this decisive decade, he added.
"Heat networks are a part of the lowest-cost pathway to decarbonising our homes and workplaces in the future but are also the bit of the jigsaw that we can be putting into place now," he said. "Penetration into the UK market is still low, despite heat representing 37% of UK greenhouse gas emissions, the largest single contributor by some way. Funding needs to be urgently directed towards reducing the environmental impact of the residential sector, particularly given the slow pace of the decline in residential emissions in comparison to those of business and transport."
Currently, just 3% of UK buildings are serviced by heat networks. "Further investment in this industry, using public and private funds, will not only drive wider sustainability targets but will boost the economy by providing more green jobs as the country emerges from the pandemic," he said.
